Abstract: A video coder includes a forward coder and a reconstruction module determining a motion compensated predicted picture from one or more previously decoded pictures in a multi-picture store. The reconstruction module includes a reference picture predictor that uses only previously decoded pictures to determine one or more predicted reference pictures. The predicted reference picture(s) are used for motion compensated prediction. The reference picture predictor may include optical flow analysis that uses a current decoded picture and that may use one or more previously decoded pictures together with affine motion analysis and image warping to determine at least a portion of at least one of the reference pictures.

Abstract: Optical safety functions are incorporated into protection switching modules which maintain redundant pathways to avoid interruptions in optical network connections. The optical safety functions which lower optical power levels upon interruptions of optical connections are effectively combined with protection switching procedures which are also triggered by interruptions in optical network connections. The interoperation of protection and safety processes keep optical power levels below hazardous levels at system points which might be accessible to human operators.

Abstract: Application message payload data elements are transformed within a network infrastructure element such as a packet data router or switch. The network element has application message transformation logic for receiving one or more packets representing an input application message logically associated with OSI network model Layer 5 or above; extracting an application message payload from the input application message; identifying one or more first content elements in the application message payload; transforming the first content elements into one or more second content elements of an output application message; and forwarding the output application message to a destination that is identified in the input application message. Transformations performed in the network element can include field reordering, field enrichment, field filtering, and presentation transformation.

Abstract: Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.

Abstract: Systems and methods for providing trigger based dynamic changes to a packet flow in a communication network are described. The trigger based dynamic changes can include upgrading and downgrading quality of service (QoS), processing the packet flow, and providing services to the packet flow. These changes can be provided by inspecting packets at a gateway for trigger conditions and setting up a proxy instance for the packet flows. The proxy can coordinate QoS changes and management of packet flows. The triggers can be based on the destination of the packet, for example, the uniform resource locator (URL) and/or by the services (e.g., email, video, messaging) that the subscriber is accessing. The triggers can also be based on the identity of the user or agreements a provider might have with an operator of network equipment for users accessing the provider's website.

Abstract: In one embodiment, a method for ensuring quality of a media message is provided. The method includes receiving information for a media message. At least a portion of the media is analyzed to determine a media quality for the media message. The method then determines if the media quality is acceptable. If the media quality is not acceptable, then an alert may be sent regarding the media quality of the media message. For example, a caller may be prompted to re-record a media message.

Also local deserializers serially receive first n-bit codes, respectively, from remote serializers, respectively. One of the first n-bit codes transmitted to one of the remote serializers indicates one of the local deserializers is not link aligned.

Abstract: An apparatus and method for emulating a shared or source distribution tree within an MPLS network. In one embodiment of the method, a router receives a multicast data packet. The router transmits the multicast data packet to a first router via a first point-to-point label switched path (LSP). The router replicates the multicast data packet to produce a replicated multicast data packet. Then the router transmits the replicated multicast data packet to a second router via a second point-to-point LSP. The first point-to-point LSP is distinct from the second point-to-point LSP.

Abstract: A system and method wherein mobile nodes scan both 802.16 and 802.11 radio channels for neighbor access points. A mobile node reports both WiMax and WiFi neighbor access points to its parent access point. A parent access point advertises both WiMax and WiFi neighbor access points to child mobile nodes to facilitate faster roaming and load balancing. A parent WiMax AP can direct a mobile node to roam to a neighbor WiFi access point that has a lighter load or offers enhanced services. As an option, a location tracking protocol is used to determine the location of a mobile node and the mobile node's parent AP advertises neighbor APs that offer services in the mobile node's location.

Abstract: In a wired data telecommunication network power sourcing equipment (PSE) coupled to a powered device (PD) carries out an inline power discovery process to verify that the PD is adapted to receive inline power, then a plurality of classification cycles are carried out to convey a series of inline power classes back to the PSE. The series of inline power classes may all be the same, in which case the PD is legacy equipment and is adapted to receive the power level corresponding to that class. If they are not all the same, information is thus conveyed to the PSE which may, for example, correspond to a specific power level to be applied or to other information.

Abstract: In one embodiment, a set of tunnels is determined that traverse a particular link connected to an intermediate node in a network. The intermediate node computes, in a coordinated path computation, paths for tunnels of the set of tunnels that do not include the particular link. The coordinated path computation considers each of the tunnels of the set of tunnels. The intermediate node selects one or more tunnels of the set of tunnels for preemption. The one or more tunnels are selected as tunnels that are reroutable by respective head-end nodes of the one or more other tunnels. Notifications are sent to one or more other intermediate nodes that inform the one or more other intermediate nodes of the one or more tunnels selected for preemption.

Abstract: In one embodiment, a spanning tree protocol (STP) is executed to assign a first port of an intermediate network device to a Root Port Role, a second port of the intermediate network device to an Alternate Port Role, a third port of the intermediate network device to a Designated Port Role, and a fourth port of the intermediate network device to a Backup Port Role. At least one bridge protocol data unit (BPDU) message is periodically sent from the first port assigned Root Port Role, the second port assigned Alternate Port Role and the fourth port assigned Backup Port Role, irrespective of receipt of any BPDU messages from neighboring intermediate network devices. In response to a failure to receive a BPDU message from a neighboring intermediate network device on the third port assigned Designated Port Role within a threshold amount of time, one or more actions are taken.
