A system of route target filtering includes an import filter receiving a plurality of routes having a next hop routing information. The import filter accepts a first subset of the routes according to an import target policy. The system further includes a re-export filter also receiving the plurality of routes. The re-export filter modifies the next hop information of a second subset of the routes, and distributes the modified routes.

System and method of virtual private network route target filtering

A system, method, and computer-readable medium for IPv4 and IPv6 migration are provided. The invocation of NAPT-PT and NAPT are minimized inside a provider's network. NAPT-PT operations are invoked at most once inside the provider's network under all situations for a media path. Moreover, he minimum required NAPT operations are performed. If there is a required NAPT operation along the media path for IPv4 address realm mismatches, no NAPT-PT operation are performed solely for protocol conversion purposes.

System and method for IPv4 and IPv6 migration

A system and method for providing quality of service guarantees in a packet-switched network is provided. A network including nodes linked together by communication links includes a management node for governing the performance of the nodes. Ingress and egress rate restrictions are defined at the nodes and the management module may disallow a portion of a requested transmission to a node if the requested transmission would result in a violation of one of the ingress and egress rate restrictions. Disallowance of a requested transmission may be made by the management node if either an ingress rate restriction of the transmitting node or an egress of the receiving node would be violated by allowance of the requested transmission.

The invention discloses a method for dynamically allocating link bandwidth on resilient packet ring. This algorithm comprises the steps of measuring a group of variables in one advertisement interval, calculating the local fair rate using the measured variables, determining an advertising rate based on the local fair rate, and transmitting the data packets with the advertising rate. Compared with existing fairness algorithms, the new algorithm introduces integration for the idle rate to achieve 100% of bandwidth utilization. It also avoids using the concept of 'congestion state' which is essential in the existing fairness algorithm.

A method is provided for providing protection for connectionless signals in a telecommunications network comprising a plurality of nodes. A first protection path is generated from each of the nodes to a destination node. A second protection path is generated from each of the nodes to the destination node. The second protection path is distinct from the first protection path. Protection traffic is routed along one of the protection paths to the destination node.

A method for allocating and resizing a link on a communication medium is provided. The utilization of an allocated link is monitored and an unused bandwidth thereof is determined. Upon request for allocation of a second link, at least a portion of the unused bandwidth is included in the bandwidth of the second link allocated. A network including two nodes and a communication medium terminated thereby is operable to provide a plurality of communication links and is operable to resize the bandwidth of the allocated links is provided. The network is operable to monitor the utilization of an allocated bandwidth of an allocated link and deallocate a part of the allocated bandwidth that is non-utilized by the allocated link. The deallocated bandwidth, or a portion thereof, may then be included in a bandwidth allocation made for allocation of an additional link.

A method and system for providing an internal topology of a node within a network includes determining asymmetric connections between traffic bearing components in a network node. An intranode connectivity is determined between the traffic bearing components based on the asymmetric connections. A model of the node indicative of the intranode connectivity is distributed to a disparate node in a network with a node. The model is used at a disparate node in determining a routing path through the network.
