  • Publication number: 20240039827
    Abstract: A router advertises an aggregated service or route that can be evaluated by other routers as a unitary segment rather than as a group of individual links/paths associated with the aggregated service or route. The aggregated service or route can be based on service and topology state information received from one or more other routers and can be advertised with the router as the nexthop for the aggregated service or route. The router can advertise an aggregated metric for the aggregated service or route for use in such evaluation. An aggregated route can be associated with different aggregated metrics for different services.

  • Patent number: 11799760
    Abstract: A method and apparatus for routing a plurality of session packets across a network toward a destination modifies each packet to include a sequence number that is different from the sequence number of other packets in the plurality of packets. Accordingly, at this point, each of the plurality of packets is transformed into a corresponding plurality of processed packets. The method also duplicates the plurality of processed packets to produce a corresponding plurality of duplicated packets. Next, the method forwards the plurality of processed packets toward the destination using a first stateful path through the network, and correspondingly forwards the plurality of duplicated packets toward the destination using a second stateful path through the network. In preferred embodiments, the first stateful path is different from the second stateful path. For example, the two paths may be entirely distinct in that they share no common intermediary elements.

  • Patent number: 11652739
    Abstract: A method routes packets from a source to a destination across an IP network having a plurality of nodes (including the source and destination), and a plurality of network segments interconnecting the plurality of nodes. The source and destination are configured to use a given service. To those ends, the method receives information relating to the given service, and forms a path between the source and the destination. The path includes a) at least one intermediate node between the source and the destination and b) a plurality of specific network segments extending from the source to the destination. The plurality of specific network segments are a sub-set of the plurality of network segments. To form the path, the method assigns the plurality of specific network segments to the network path between the source and the destination as a function of the information relating to the given service.

  • Patent number: 11503116
    Abstract: A method and apparatus form and/or define a network topology in a Layer 3 network with a plurality of nodes, where each node has at least one interface. To that end, the method defines a plurality of neighborhoods, and assigns at least one interface of each node to at least one of the neighborhoods. The method also assigns a communication role to each interface so that each communication role is effective relative to one of the plurality of neighborhoods. The method then enables communication between the interfaces of the plurality of nodes as a function of the neighborhoods and the communication roles.

  • Publication number: 20220200915
    Abstract: Techniques are disclosed for the detection of different states of a session comprising a bidirectional flow of network traffic between client devices so as to enable a network device to apply different network policies to different states of the session. In one example, a computing device identifies multiple states of a session and defines a plurality of network policies. Each network policy defines performance requirements for network traffic during each state of the session. A network device receives the plurality of network policies and determines a state of the session. The network device selects a path based on the performance requirements of the network policy associated with the determined state of the session. The network device forwards traffic associated with the session along the selected path while the session is in the determined state.
