Abstract

Novel tools and techniques are provided for implementing intelligent alert automation (“IAA”). In various embodiments, IAA receives alert/event feeds from several different alerting and ticketing systems via input Redis queues, and uses a triage system to determine whether to process the alert/event or disregard it. If so, IAA may create a flow instance, assign a unique instance ID, and place the flow instance in one of a plurality of jobs queues based on alert/event type and/or or source. An abattoir system retrieves a flow instance from one of the jobs queues (in order of the queue's priority), and processes the next node or step in the flow instance. The flow instance is placed back into the jobs queue for subsequent processing by the same or different abattoir system until no additional nodes or steps remain in the flow, at which point the flow instance is considered complete.

Abstract

Improved methods for retrieval of content from CDNs is provided that includes a rendezvous controller that receives information of an identification of content being requested and an estimated location of a content requesting device. Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server.

Abstract

Aspects of the present disclosure involve systems for providing multiple egress routes from a telecommunications network for a client of the network. In general, the system provides for a client of the network to receive intended packets of information through multiple connections to the network such that load balancing and failover services for traffic to the customer are provided. The process and system allow for telecommunications network to utilize a common next-hop value of announced border gateway protocol (BGP) routes to advertise multiple routes to reach a destination customer network or address. By utilizing a common next-hop value in the announced BGP information, the devices of the network may load balance communication packets to the destination customer or address among the multiple egress locations from the network, as well as providing fast failover to alternate routes when a failure at the network or customer occurs.

Abstract

Implementations described and claimed herein provide systems and methods for a configurable optical peering fabric to dynamically create a connection between participant sites without any physical site limitations or necessity of specialized client and network provider equipment being located within such a facility. Client sites to a network may connect to a configurable switching element to be interconnected to other client sites in response to a request to connect the first client site with a second site, also connected to network, via the switching element. A request may trigger verification of the requested and, upon validation, transmission of an instruction to the switching element to enable the cross connect within the switching element. The first site and the second site may thus be interconnected via the switching element in response to the request, without the need to co-locate equipment or to manually install a jumper between client equipment.

Abstract

Systems and methods are provided for generating a network ingress filter based on both a customer's route object and recent traffic data for the customer. In examples, even though a customer of a provider network may have many routing prefixes in its route object, the customer may genuinely generate traffic from only a very small percentage of such prefixes. Accordingly, a combination of a system to generate all the prefixes based on a route object, along with the results of collected traffic data, may be used to generate a much smaller ingress filter. In examples, this filter may comprise an intersection of the prefixes generated by the customer's route object and the prefixes that have been actively generating traffic on the inbound interface of the router (or other provider edge system). This results in a smaller ingress filter that can be reliably configured on the provider edge system.

Abstract

A method is disclosed for testing network devices for networks with a large traffic load utilizing one or more traffic load amplifiers to amplify the traffic load. The load amplifiers connected to the device may receive packets of an initial traffic load, multiply or copy the received packet, alter the destination address information in the header of the copied packets to generate packets with different destination addresses, and transmit the altered packets back to the device for further routing. The altered or copied packets may then be routed via the device back to the load amplifier for further amplification. Through this amplification process, a small initial load of packets may be amplified over and over by the load amplifiers until a target traffic load is achieved at the device to test the device performance at a large traffic load.

Abstract

Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.

Abstract

A dynamic SRMS (DSRMS) in a MPLS network generates unique segment identifiers for nodes of the network lacking segment identifiers (SIDs). The DSRMS receives network information from other nodes of the network that may include, for example, Internal Gateway Protocol (IGP) routing information, advertised prefix values for the nodes, and label values used in MPLS routing. The DSRMS analyzes the information and identifies nodes of the network that are not associated with a SID. For each identified node, the DSRMS generates a unique SID and then announces the SID to other nodes within the network. Generating the unique SID may include executing a hashing function using the IP address of the identified node as an input.

Abstract

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for determining an estimated capacity for providing data from a telecommunications network to a plurality of end users. In one implementation, the estimated capacity for delivering the data to the end users is per transmission path or per access network connected to the telecommunications network. This information may be aggregated into a traffic flow table that illustrates the traffic flow and available capacity to one or more end user networks. Through analysis of the traffic flow table, the system determines an estimated available capacity to provide the data to the end users. The traffic flow table thus provides a more accurate estimate of the capacity of the telecommunications network to provide the data to the end users over previous capacity estimates.

A computer-implemented method may include listing in a suspect list every received stimulus including the faulty stimulus, and implicitly testing the stimuli by respectively acting upon those stimuli by a software application. Responsive to successfully acting upon each of the stimuli besides the faulty stimulus, each non-faulty stimulus is deleted from the suspect list and, responsive to such deletion, made available to a downstream node. Responsive to acting upon the faulty stimulus, the software application crashes which leaves the faulty stimulus listed in the suspect list. The software application then restarts and deems the faulty stimulus as being faulty based upon the faulty stimulus still being listed in the suspect list after the restart.

Abstract

Examples described herein relate to standardizing content requests and responses in a content delivery network (CDN). An edge node receives a control object including sets of instructions each implementing portions of a customer’s business logic. The edge node may receive, from a client, a content request identifying a content item, and may apply a set of the instructions which causes the edge node to (i) determine whether any changes are needed for the benefit of a cache server and whether any changes are need for the benefit of an origin server, and (ii) generate a processed client request identifying the content item and including, if needed, any changes for the benefit of the cache server and the origin server. The edge node transmits the processed client request to the cache server, receives a response from the cache server, and transmits a processed client response to the client.

Abstract

Systems and methods for routing traffic through a network along Label-Switched Paths (LSPs) that may extend across multiple autonomous systems include performing Internet Protocol (IP) routing lookups as a packet is transmitted along the LSP. In one implementation, a packet having a predetermined value (which may be inserted by an upstream network device) is received at a network device after travelling along a first segment of an LSP. In response to identifying the predetermined label value of the packet, the network device may perform an IP routing lookup using IP routing information included in the packet to identify a next hop for the packet. The network device may then update a label of the packet such that the packet is routed along a second segment of the LSP and transmit the communication packet to the next hop.

Abstract

A security platform of a data network is provided that includes security services for computing devices in communication with the data network. The security platform may apply a security policy to the computing devices when accessing the Internet via a home network (or other customer network) and when accessing the Internet via a public or third party network. To provide security services to computing devices via the home network, the security platform may communicate with a security agent application executed on the router (or other gateway device) of the home network. In addition, each of the devices identified by the security profile for the home network may be instructed or otherwise be provided a security agent application for execution on the computing devices. The security agent application may communicate with the security platform when the computing device connects to the Internet over a third party or public access point.

Abstract

Aspects of the present disclosure involve systems, methods, for encoding a firewall ruleset into one or more bit arrays for fast determination of processing of a received communication packet by a firewall device associated with a network. Through this bitmap, a number of computation operations needed to determine a processing rule for a received packet is significantly reduced compared to the traditional approach of using a hash or a longest prefix match technique. Rather, determining a processing rule for a received packet may include determining a bit value within one or more arrays. In one implementation, a firewall rule may be encoded into a 64-bit array of bit values in which each bit of the array corresponds to a particular processing rule for a particular network address. The firewall rule may be encoded into a bitmap array of bit values by asserting a particular bit within the array.

Abstract

Novel tools and techniques are provided for implementing name-based routing through networks. In various embodiments, a broker manager in each of a plurality of networks may receive a subscription request for a network device from a client device, each device being locally accessible or disposed in an upstream or downstream network. The broker manager uses its client broker to communicate with a locally accessible client device, and uses its mediator broker (and, sometimes, an intermediate device(s)) to communicate with a locally accessible network device. The broker manager otherwise uses its messaging brokers to communicate with control channels of one or more networks. Once subscription with the network device has been established, any commands and responses between the client device and the network device may be routed over pub/sub channels via the broker managers and their brokers using name-based routing, without routing based on IP address of the network device.

Abstract

Systems and methods for managing network devices include performing clustering operations for network devices based on attributes of the network devices. By comparing the results of subsequent clustering operations, changes in network device attributes can be readily identified and any network devices for which attributes have changed may be subject to further investigation or remedial action (e.g., blocking traffic to/from the network device). Clustering may also be used to conduct an inventory of network devices by identifying groups of network devices that have similar attributes.

Abstract

External customer data (ECD) may be efficiently stored in a network. When ECD is received at an edge node, the node may determine if the ECD is subject to a compiling procedure. For example, if the ECD comprises a list of entries that all have the same data type, the ECD may be placed into an array, and the array may be sorted and stored. In other examples, if the ECD received at a node includes references to other ECD, the referenced ECD may be retrieved, and the received ECD and referenced ECD may be combined and stored. In other examples, the ECD received at the node may be script instructions that can then be compiled into, and stored as, a runtime version. Any compiled ECD stored at nodes may be subject to the same invalidation and expiration policies as the uncompiled ECD from which it was derived.

This may result in an alternate billing option for the customer's use of the system. Further, a telecommunications network administrator may provide access to the collaboration conferencing system based on a total number of concurrently utilized ports rather than on a per conference or per minute basis. With the information of the number of purchased ports by the customer, the administrator may more accurately predict an available capacity for the collaboration conferencing system needed to support all of the users of the system and the potential collaboration conferences.

Abstract

Provided is a content delivery method and architecture for ways to improve the caching of content at one or more content providing devices of a Content Delivery Network (CDN). In particular, systems and methods are disclosed that vary the requirements to store resources or content within a caching device using a dynamic popularity threshold. This popularity threshold may be varied based on a measured fullness of the storage capacity of the cache device. In another example, the dynamic popularity threshold may be further varied based on a cache pressure, which is an indication of how often the cache replaces stored items with new items. The adjustment to the popularity threshold for caching particular content at the caching device may thus be based on a number of requests for content received at the device to tune the caching procedure for a particular region of the CDN.

Abstract

Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

Abstract

Implementations described and claimed herein provide systems and methods for correlating one or more service areas of a network with one or more geolocation coordinates to determine available services for customers to the network. A service polygon may be generated that define an area in which a particular service offered by a communications network is available. The boundaries of the service polygons may be adjusted based on information corresponding to physical features of the initial area. The service polygons may aid a communications network in providing a list of available services to potential customers or devices connected to the network by determining one or more geolocation coordinate values of a potential connection site and comparing the values to the service polygons. A network management system may determine the available services, current or in the future, to offer such services to a customer to the network.

Abstract

In an embodiment, a method monitors a plurality of data streams passing through a router in the connectivity service provider environment, and for each of the data streams, periodically samples packets at the router. The method further generates a stream signature based at least on the payload of the sampled packets. The method further includes, for each generated stream signature, attaching information to the stream signature. Such information may, for example, include time-stamp information for the stream signature, or an identification of the router. The method may further comprise storing the stream signatures corresponding to the data streams in a database. The stored stream signatures may be compared to determine matching stream signatures. Matching signatures may identify data streams that carry identical or similar content.

Abstract

Examples of the present disclosure describe systems and methods relating to adaptive virtual services. In an example, a user specifies a device configuration for a platform device. As a result, a service provider installs selected virtual-network functions and defines network connections as specified by the device configuration. Management software may also be installed, thereby enabling the service provider to communicate with and remotely manage the platform device. The installed virtual-network functions are activated on the platform device once it is delivered to the user. In some instances, the user changes the device configuration. For example, the user may install new virtual-network functions, reconfigure or remove existing virtual-network functions, or change defined network connections. As a result, the service provider reconfigures the platform device accordingly. Thus, the user need not purchase new specialized hardware in order to change the available functions of the computer network.

Abstract

Novel tools and techniques are provided for implementing intent-based orchestration using network parsimony trees. In various embodiments, in response to receiving a request for network services that comprises desired characteristics and performance parameters for the requested network services without information regarding specific hardware, hardware type, location, or network, a computing system might generate a request-based parsimony tree based on the desired characteristics and performance parameters. The computing system might access, from a datastore, a plurality of network-based parsimony trees that are each generated based on measured network metrics, might compare the request-based parsimony tree with each of one or more network-based parsimony trees to determine a fitness score for each network-based parsimony tree, and might identify a best-fit network-based parsimony tree based on the fitness scores. The computing system might identify and might allocate network resources based on the identified best-fit network-based parsimony tree, for providing the requested network services.

Abstract

Systems and methods for managing configuration changes to a network are provided. In examples, the configuration rules are received and stored in a staging directory. If the configuration rules are validated, the rules are moved to a running directory. Thereafter a request to make a change to a configuration parameter is received. The request may comprise a configuration change object, and the configuration change object may be stored in the staging directory. The configuration change object may be evaluated against the rule (and other rules of the network), and it may be moved to the running directory only after satisfying all applicable rules. In some examples, applying the rule(s) may include determining whether the configuration change exceeds a network limit on changes of a particular type with a preset time period.

Abstract

In an embodiment, a computer implemented method receives flow data for a network flows. The method extracts a tuple from the flow data and calculates long-term and short-term trends based at least in part on the tuple. The long-term and short-term trends are compared to determine whether a potential network anomaly exists. If a potential network anomaly does exist, the method initiates a heavy hitter detection algorithm. The method forms a low-complexity intermediate stage of processing that enables a high-complexity heavy hitter detection algorithm to execute when heavy hitters are likely to be detected.

Abstract

A routing system can provide a Dynamic-Hybrid Forwarding Information Base (DHFIB). A control component of the routing system can build a routing table that includes routing information (e.g., prefixes, addresses, etc.) for use by a first routing component. The routing table can be ordered or ranked based on traffic information from the first routing component. Then, the control component can create the DHFIB from the routing table, wherein the DHFIB is a portion of the routing table and related to the first routing component. As such, the portion of the routing table selected for the DHFIB can be the set of prefixes in the routing table that represent the most frequently routed or most important prefixes in the routing table. Finally, the control component can forward the DHFIB to the first routing component to allow the routing component to route communications.

Abstract

Aspects of present disclosure include devices within a transmission path of streamed content forwarding received data packets of the stream to the next device or “hop” in the path prior to buffering the data packet at the device. In this method, typical buffering of the data stream may therefore occur at the destination device for presentation at a consuming device, while the devices along the transmission path may transmit a received packet before buffering. Further, devices along the path may also buffer the content stream after forwarding to fill subsequent requests for dropped data packets of the content stream. Also, in response to receiving the request for the content stream, a device may first transmit a portion of the contents of the gateway buffer to the requesting device to fill a respective buffer at the receiving device.

Abstract

Systems and methods for network quality testing are provided. Synthetic traffic may be sent through a first flow path and a second flow path. The second flow path includes a portion apportionable to the first flow path, internal to a server, and a portion apportionable to an external flow path, external to the server. Durations of traffic traveling through the first flow path and the second flow path are compared to determine the portion of the second flow path apportionable to the external flow path. In an example, time stamping may be performed by component(s) of the server, such as a kernel, to determine the durations of the traffic traveling through the first flow path and the second flow path.

Abstract

Aspects of the present disclosure involve a CDN utilizing a Direct Server Return (DSR) request command to create a tunnel from one content server to another content server of the CDN. Through the DSR tunnel, a request for content may be served from a content server that is more advantageous for the CDN for any number of reasons, such as from a content server that is logically closer to the content server. In determining when a DSR tunnel is created to provide the content, the CDN may access a database storing various information concerning the CDN, such as the location of egress gateways of the CDN in relation to one or more content servers, connecting network location information, the capabilities of one or more content servers, and/or load information of available content servers.

Abstract

Improved methods for retrieval of content from CDNs is provided that includes a rendezvous controller that receives information of an identification of content being requested and an estimated location of a content requesting device. Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server.

Abstract

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for controlling a congestion window (CWND) value of a communication session of a CDN. In particular, a content server may analyze a request to determine or receive an indication of the type of content being requested. The content server may then set the initial CWND based on the type of content being requested. For example, the content server may set a relatively high CWND value for requested content that is not particularly large, such as image files or text, so that the data of the content is received at the client device quickly. For larger files or files that a have a determined smaller urgency, the initial CWND may be set at a lower value to ensure that providing the data of the content does not congest the link between the devices.

Abstract

A DNS resolution request for a hostname of a CDN is received. An edge server of the CDN may be identified, which may be associated with a subnet. The subnet is used to generate a response IP address, where the remaining bits of the response IP address may be used to store requestor information (e.g., a requestor IP address). When a client computing device uses the response IP address to access the edge server, requestor information is extracted and associated with client computing device information (e.g., an IP address and/or location, etc.) in an association record. Association records may be used to determine predicted characteristics for devices served by a requestor. When the authoritative DNS server resolves a request from the requestor, such predicted characteristics may be used rather than relying solely on information about a requestor. Thus, an edge server proximate to the predicted location may be returned instead.

Abstract

The present disclosure describes a system and method for providing automated policy enforcement. The system and method may be implemented by a service provider to enforce a policy related to copyright infringement activities. According to an example, the policy may define a system of penalty (strike) levels for violations of the policy up to a maximum number of strikes. When a notification of a policy violation is received, the system may operate to determine whether to issue a strike in association with the notification. When a determination is made to issue a strike in association with a received notification a set of enforcement actions to perform in association with the issued strike may be selected and executed. The set of enforcement actions may terminate detected copyright infringement activities and reduce or otherwise limit the service provider's liabilities when such copyright infringement activities may occur.

Abstract

Aspects of the present disclosure involve systems, methods, for encoding a firewall ruleset into one or more bit arrays for fast determination of processing of a received communication packet by a firewall device associated with a network. Through this bitmap, a number of computation operations needed to determine a processing rule for a received packet is significantly reduced compared to the traditional approach of using a hash or a longest prefix match technique. Rather, determining a processing rule for a received packet may include determining a bit value within one or more arrays. In one implementation, a firewall rule may be encoded into a 64-bit array of bit values in which each bit of the array corresponds to a particular processing rule for a particular network address. The firewall rule may be encoded into a bitmap array of bit values by asserting a particular bit within the array.
