Abstract

A system and associated methods provide procedures for establishing multicast connections and forwarding multicast content from a source to a subscriber when an ingress provider edge in communication with the subscriber is connected to an egress provider edge device belonging to an EVPN instance, especially in cases where the egress provider edge device is not receiving content from the source. The system configures "backup" provider edge devices belonging to the EVPN instance to temporarily forward the multicast content to the egress provider edge device on behalf of the source, enabling the ingress provider edge device and subscriber to continue to receive the multicast content from the source while the multicast network adjusts to recognize a new egress provider edge device. Methods of establishing connections between the ingress provider edge device and the correct egress provider edge device are also provided to avoid flooding and inefficient content forwarding throughout the network.

Abstract

Techniques for leveraging a software defined tracking architecture to track endpoint connected to a network fabric are described. An orchestrator of a network fabric receives port information indicating a port of a fabric edge device to which an endpoint is connected. The orchestrator transmits the port information to a netw ork node in the network fabric enabling data-plane traffic inspection. Using the port information, the network node detects traffic having a destination address corresponding to the endpoint. The network node transmits an indication that traffic was received by the network node having the destination address corresponding to the endpoint. Finally, onboarding of the endpoint into the network fabric is triggered at the fabric edge device.

Abstract

Techniques for leveraging a distributed Domain Name System (DNS) infrastructure for preserving Personally Identifiable Information (PII) data for distributed resolvers using a hash to policy pair (HPP) database are described. A DNS security service receives metadata including PII associated with a client. A cryptographic hash function is applied to the metadata including PII associated with the client to generate a client hash value. A client HPP is created by mapping the client hash value to a set of DNS policy instructions associated with the client. The client HPP is stored in a HPP database. A distributed resolver is authorized to provide DN S services to the client. Finally, the HPP database is published to the distributed resolver.

Abstract

Techniques are described herein for implementing and using a secure access service edge (SASE) exchange system to allow SASE providers to share SASE services with other providers. A SASE exchange system may be used by any number of SASE providers to support SASE roaming by user endpoints between different SASE providers. A user endpoint may use SASE roaming to access additional sets of SASE services and capabilities that cannot be provided by a home SASE provider and/or other current SASE provider(s) of the user endpoint. In some examples, a SASE exchange system may be used to transition user endpoints from one SASE provider to another. Additionally or alternatively, the SASE exchange system may determine a combination of SASE providers that can be used to provide different subsets of shared SASE services/ capabilities to a user endpoint.

Abstract

Techniques for monitoring data transport in a network virtualization function chain. A path tracing packet is generated having a Midpoint Compressed Data (MCD) to collect path tracing information of the network virtualization function chain. The network virtualization function node is configured to record an MCD containing Wide Local Path Tracing Identification (WL PT ID). The WL PT ID includes a first field having a value that indicates that a non-standard path tracing format is to be used and has a second field that indicates a particular path tracing format to be used. The path tracing packet is passed through the network virtualization chain and is then received back again after passing through the network virtualization function chain. Data collected by the path tracing packet is then analyzed to determine which network virtualization function nodes and network virtualization function chains the path tracing packet passed through and the amount of time taken for the path tracing packet to pass through the network virtualization function chain.

Abstract

A network of access points (AP) in a high-density environment may be provided. A number of packet transmission retries for one or more of the AP may be determined by setting a number, m, of retries for transmitting a data packet, where m is the upper limit of the number of retries. Data packets are then transmitted m times. Upon transmitting the data packet m times, a success probability SP(u,m) for transmission of the data packet, where u is the number of users, may be calculated. The transmission of the data packet may be repeated m-x times where x is an integer. Upon calculating the success probability for m-x times, a success probability SP(u,m-x) for transmission of the data packet may be calculated. If SP (u,m-x) is larger than SP(u,m) then x may be decreased by one and actions (b)-(f) may be repeated. If SP (u,m-x) is not larger than SP(u,m) then m-x may be set as the maximum number of retries for the data packet.

Abstract

Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority. The controller may then create a negotiation between the victim AP and the infringing AP, wherein the negotiation comprises managing future transmissions of the victim AP and the infringing AP.

Abstract

Techniques for using more-specific routing to perform scalable Layer-2 (L2) stretching of subnets across hybrid-cloud environments. Routing tables in a public cloud may allow for routes that are more specific than the default local route, and the more-specific routes may be used to send all traffic to a dedicated, cloud router. The more-specific routes are set up for a VPC where a subnet resides such that the more specific-routes cover at least a portion of subnet range. The next hop for the more-specific routes point to the cloud router which is capable of doing host routing and segmentation extension. Thus, traffic originating from endpoints in a VPC is routed to the cloud router, and the cloud router determines whether the traffic is to be re-routed back to a destination endpoint in the VPC (or another cloud location), or sent to a destination endpoint residing in the on-premises site.

Abstract

Techniques for migrating on-premises and/or cloud-based workloads to follow a network session as it potentially migrates, due to multipathing techniques, across multiple edge and/or cloud datacenters. The techniques may include determining, by a controller of a network, that a traffic flow between an endpoint device and a workload has migrated to a different path of a multipath flow such that the traffic flow terminates at a different termination point than the workload. Based at least in part on determining that the traffic flow has migrated, the controller may cause a migration of a state of the workload to a location associated with the different termination point. That is, the controller may cause the workload to be migrated in its current state, which may be specific to the endpoint device, to follow the traffic flow.

Abstract

Methods and a system described herein manage the power of loTs and smart devices operating on a wireless network. When an access point coupled to the network receives a low power indication from a battery-powered loT or smart device, it may take several actions in response. In one case, it extends the target wake time to become longer and longer to preserve the device' s battery. In addition, the device changes its operation to conserve power. In another case, it provides power over the wireless network to the wireless device. The access point restores the target wake time when the device returns to a power-ok condition. The device resumes operation according to the parameters in effect before the low power condition occurs.

Abstract

Techniques for leveraging efficient metadata communications to improve domain name system (DNS) security are described. The DNS service uses a hash value to uniquely identify a client, and detect any change in metadata in order to keep policies up-to-date for the client. In an example method a first DNS query for a client device is intercepted. A cryptographic hash function is applied to metadata associated with the client device to generate a hash value. The hash value is added to an additional records section of the first DNS query to generate a second DNS query. The second DNS query is transmitted to a DNS service. The metadata associated with the client device is transmitted to the DNS service on an out-of-band encrypted channel. A DNS response, including the hash value, is received from the DNS service and transmitted to the client device.

Abstract

Techniques for a hub node to, provisioned in a network site of a hub and spoke overlay network, to receive a network advertisement from the spoke, decode network routing requirements from a border gateway protocol (BGP) large community' associated with the network advertisement, and store the network routing requirements in association with a route associated with the spoke. The routing requirements may indicate one or more service(s) to be applied to the packet, a trust level associated with the spoke, and/or a. trust zone associated with the spoke. The hub node may receive a packet from the spoke to be transmitted to destination spoke. The hub node may then route the packet to the destination spoke, drop the packet, or send the packet to a service node configured to apply the one or more services to the packet based on the routing requirements.

Abstract

Described herein are systems and methods for reducing collisions in a wireless network with overlapping basic service sets by synchronizing contention slots among stations (access points or non-access point clients), some of which are out of range, competing for the use of the wireless medium. In some embodiments, the contention slots of competing stations are synchronized by controlling the time of transmission and the time of the spacing between frames to be an integer multiple of the time of a contention slot. In some embodiments, slot boundaries are enforced by controlling guard intervals or by trigger-based uplink communications. In other embodiments, a central network controller, such as a network controller, synchronizes slots when an access point or station joins the wireless network or uses a neighbor discovery protocol among access points. The contention slots are synchronous in all cases throughout the overlapping basic service sets.

Abstract

Methods and a system described herein form collections of stations based on capabilities and classification of the station and on radio capacity and link budgets of the bands in which the stations operate. Once a collection is formed, a check occurs to determine if there is a rebalancing event, such as a change in the capabilities and classification of a station or a change in the radio capacity and link budgets. If so, then the stations are reassigned to different collections. If no rebalancing event occurs, then the assignment is checked to determine if the loads on the links are well-balanced. If so, a radio link recommendation is sent to the stations.
