摘要： An application programming interface for use in a network device includes at least one control module that is capable of controlling a forwarding plane of the network device. In particular, the network device forwards packets across a network, and includes the forward plane for processing data packets. The application programming interface includes an input module that receives function calls, at least one control module (mentioned above) that receives input control data via the function calls, and an output module that forwards output control data from the control module. The control module produces the output control data based upon the input control data. The output control data is capable of controlling execution of the forwarding plane.

摘要： A system, device, and method for distributing access control information in a communication system uses a reliable multicast mechanism for distributing access control information by a main server to multiple access control devices. A dedicated multicast group is established for distributing the access control information, and each access control device joins the dedicated multicast group. A reliable multicast mechanism is used to distribute the access control information to the multicast group members. Each access la control device obtains the access control information using the reliable multicast mechanism, and stores the access control information in a database for later use in making receiver access control decisions.

摘要： A system, device, and method for distributing link state information in a communication network combines a link state routing protocol with a sliding window mechanism in order to efficiently distribute link state information. The sliding window mechanism permits a predetermined number of unacknowledged link state advertisement protocol messages to be outstanding at any given time. Unacknowledged link state advertisement protocol messages are retransmitted after a predetermined timeout period.

摘要： A system, device, and method for receiver access control in a multicast communication network uses a policy service to determine whether a subscriber device can be admitted to a multicast group. The subscriber device accesses the multicast communication network via an access device. The access device uses a policy service to obtain a policy decision from a policy server, where the policy decision indicates whether or not the subscriber device can be admitted to the multicast group. The access device enforces the policy decision by admitting the subscriber device to the multicast group if and only if the policy decision indicates that the subscriber device can be admitted to the multicast group.

摘要： An apparatus and method of managing a router table that includes inter-router protocol information indexes the routing table to the inter-router protocol information. Such inter-router protocol information may include data identifying the name of protocol itself, or other related information. To that end, the routing information within the routing table first is indexed based upon the inter-routing protocol information to produce indexed routing information. A given routing information request then may be received. The given request requests both routing information from the routing table, and information relating to a given inter-router protocol. The indexed routing information then is accessed to retrieve the information requested in the request.

摘要： In a technique for priority forwarding, an upper layer protocol that requires priority forwarding includes a priority function that is invoked by a lower layer protocol in order to obtain the priority for a message. The upper layer protocol provides the priority function to the lower layer protocol when the upper layer protocol is installed in the protocol stack. The lower layer protocol invokes the priority function before passing a message to the upper layer protocol in order to determine a priority for the message. The lower layer protocol places the message in the appropriate queue based upon the priority indicator obtained from the upper layer protocol's priority function.

摘要： In a system, device, and method for expediting reconvergence in a communication network, a first indication of a communication link failure prompts a node to compute new routes. Upon receiving the first indication of the communication link failure, the node determines the nodes that are associated with the failed communication link. The node disassociates the failed communication link from all such nodes, and computes new routes. Subsequent indications of the same communication link failure are ignored.

摘要： A link state advertisement protocol message received from an originating device over an inbound interface is forwarded by the fast path according to a minimum spanning tree. Specifically, a minimum spanning tree is established based upon the topology information obtained from the link state routing protocol. The minimum spanning tree identifies the outbound interfaces to which the link state advertisement protocol message is to be forwarded. The link state advertisement protocol message is forwarded be the fast path according to the minimum spanning tree, and more specifically the link state advertisement protocol message is forwarded by the fast path to all outbound interfaces identified by the minimum spanning tree other than the inbound interface. The link state advertisement protocol message continues to be processed and forwarded by the control plane as usual for robustness.

摘要： A system, device, and method for sending keep-alive messages in a communication network involves determining a reliability factor for communicating with a neighbor and setting the frequency for sending keep-alive messages to the neighbor based upon the reliability factor. The reliability factor is determined based upon the reliability of the neighbor as well as the reliability of the communication link to the neighbor. The frequency for sending keep-alive messages to the neighbor is relatively high if the reliability factor is low. The frequency for sending keep-alive messages to the neighbor is relatively low if the reliability factor is high. The frequency for sending keep-alive messages to the neighbor is dynamically adjusted based upon an updated reliability factor.

摘要： An apparatus and method of communicating messages between a first application and a second application establishes a path between the first application and the second application. At least one channel is defined within the path, where each of the at least one channels is designated as forwarding a single type of message between the first application and the second application. A handler is assigned to each channel. In preferred embodiments, the handler processes messages in its assigned channel in a uniform manner.
