A content delivery resource in a cable network receives a request for specified content. The content delivery resource retrieves profile information assigned to the subscriber domain. The profile information indicates multiple different playback formats assigned to the subscriber domain. To service the request, the content delivery resource utilizes the profile information associated with the subscriber domain to select versions of the specified content encoded in accordance with the multiple different playback formats. The content delivery resource then initiates transmission of the versions of the specified content in the multiple different playback formats to the subscriber domain for playback on multiple types of playback devices.
A wireless access point employs a wireless configuration database for retrieving a stored wireless profile corresponding to a subscriber device from a remote location that enables the user to establish an Internet connection using their subscriber device with the same network identifiers and settings employed from the home wireless profile. The network identifier is typically an SSID (Service Set Identification), and labels the wireless configuration using a mnemonic name familiar to the user. The wireless configuration also denotes authentication and security (passphrase) tokens required for access, and would therefore enable the user to sign on at the remote wireless access point using the passphrase already known from their home WiFi arrangement. Subsequent attempts automatically establishing a connection to the subscriber device upon detection and authentication using the retrieved wireless profile without broadcasting an open SSID receivable by other wireless devices within range.
Techniques disclosed herein include systems and methods for providing active mobility of Wi-Fi enabled devices within a given wireless local area network (WLAN).

METHODS AND APPARATUS FOR SUPPORTING CONTENT DISTRIBUTION
Methods and apparatus for supporting content delivery service are described. In accordance with the invention content can be supplied to temporary storage of a regional or local server used to supply the content to a customer's premises when the requested content is not already available in the regional or local server. A content server hierarchy may be implemented with servers higher up in the hierarchy including more content, e.g., titles, than the number of titles stored in the lower level servers. By storing less frequently accessed content in servers higher in the hierarchy and frequently requested titles lower in the hierarchy, a vast number of titles can be supported without overburdening the storage available at local and regional servers. In addition, a national or other server high in the hierarchy can be used to store, move, and distribute local or other content as part of an on demand service.

METHODS AND APPARATUS FOR SELECTING DIGITAL TECHNOLOGY FOR PROGRAMMING AND DATA DELIVERY
Methods and apparatus for selecting digital technology for programming and data ~ delivery over, e.g., a content-based network. In one embodiment, the network comprises an HFC cable or satellite network that includes a server process interfacing with a plurality of customer premises equipment (CPE), and/or associated client devices, each having different capabilities profiles. The server determines the one or more capabilities possessed by the CPE, and evaluates one or more program or content choices for possible delivery to that CPE based on its profile. The server generates a list of programs or content based on this evaluation, and transmits this list to the CPE, which displays the list for viewing by a user. The user is therefore offered a list of available content that is compatible with their specific configuration. A business and operational rules engine is also optionally employed to control the operation of the foregoing processes to accomplish particular business or operational goals.
Methods and apparatus for assigning physical channels in a content-based network. In an exemplary embodiment, the network comprises a cable television network having a plurality of cable modems, and the physical channels are assigned to the cable modems based at least in part on any multicast transmissions that may exist on the system. When two cable modems are receiving the same multicast transmission, the invention causes tuning of one or more of the cable modems to the same physical channel in order to limit the total number multicast transmissions on the network. Multicast transmissions typically comprise video or audio information, but other types of information may also be multicast according to the invention. In another embodiment, a multicast transmission list (containing a list of multicast transmissions and the corresponding physical channels) is sent to the set of cable modems. This list is used by the modems (or associated CPE) to manage channel allocation and tuning.
Methods and apparatus for dynamically and automatically allocating network resources through anticipatory analysis and control. In an exemplary embodiment, the network comprises a broadcast switched digital architecture, and network bandwidth allocation to multiple digital program streams is performed by processing historical user tuning data, which is obtained directly from the subscriber's consumer premises equipment (e.g., DSTB). When an increase or decrease in bandwidth required to support certain programs is anticipated, network resource re-allocation is performed automatically by a software process running on the switching server. In this fashion, speculative but "intelligent" projections of bandwidth and program stream requirements can be made automatically by the server software, without operator intervention. The server also optionally dictates the optimal monitoring and data collection parameters to the DSTB.

METHOD TO BLOCK UNAUTHORIZED ACCESS TO TFTP SERVER CONFIGURATION FILES
The present invention teaches methods and systems for blocking unauthorized access to cable modem configuration files stored on trivial file transfer protocol (TFTP) servers. Filenames are modified by the DHCP to incorporate an authentication key (and optional cloaking) prior to transmission to the cable modem. When the TFTP server receives a modified filename, it also generates an authentication key. The authentication keys must match in order for the cable modem to receive the configuration file requested. At a minimum, authentication keys depend upon the un-modified filename, the cable modem IP address and a "coordination pass phrase" known to the TFTP server and DHCP server, but not known to the cable modem. Variations include optional cloaking, various actions performed for non-matching authentication keys, selection of authentication key generating algorithm and inclusion of cable modem MAC address in the authentication key for all cable modems or for premium service customer cable modems.

The cable modem termination system (CMTS) incorporates a data gateway agent that filters unauthorized traffic thereby eliminating consumption based subscribers from being responsible for related service charges. Embodiments incorporate the use of packet filtering, hybrid stateful packet filtering, content filtering, application layer filtering an time based filtering. Greater acceptance of consumption based billing is achieved by having the filter settings directed by the subscriber.
A system and method for managing provisioning parameters in a cable network. A dynamic TFTP (DTFTP) server and a CMTS manage the provisioning of devices in a cable network. The DTFTP server and the CMTS share common provisioning parameters. A provisioning parameter has a name and a value. When channel are made in the value of a provisioning parameter that is also used by n CMTSs supported by that DTFTP server, the DTFTP server securely communicates the new provisioning parameter values to each such CMTS. In one embodiment of the present invention, the DTFTP server pushes the new provisioning parameter values to the CMTSs. In another embodiment of the present invention, a poller pulls the provisioning parameters from the DTFTP server to a central datastore where changes in provisioning parameters used by the CMTSs supported by the DTFTP are identified. The changed provisioning parameter values are pushed from the central datastore to the CMTSs.

SYSTEM AND METHOD FOR PROVISIONING A PROVISIONABLE NETWORK DEVICE WITH A DYNAMICALLY GENERATED BOOT FILE USING A SERVER
A system and method for provisioning provisionable network devices with a dynamically created boot file using a server. A dynamic configuration server (DCS) generates one or more boot file templates, each boot file template comprising attributes having a name and value. A boot file request comprising a boot file template identifier is received by the DNS from a provisionable network device. The DCS uses the boot file template identifier to select a boot file template for the provisionable network device and to assign attribute values to the attributes of the selected boot file template. The boot file is used to provision the provisionable network device.

The present invention teaches methods and systems for monitoring and controlling bandwidth usage between an internal local area network and an external network. By providing controls from inside the external network connectivity point, greater detail in bandwidth control is possible. This in turn leads to less restrictive bandwidth restricting algorithms. Bandwidth restricting algorithms include various bandwidth limiting techniques. One such technique uses prioritized data transfer limits applied on an application, process or network interface basis. Another technique uses a configurable weighting factor for real-time prioritization of data traffic. Other techniques incorporate quality of service or model predictive control based bandwidth limiting.
