  • 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.

  • Patent number: 11496390
    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: 11075836
    Abstract: In exemplary embodiments of the present invention, a router determines whether or not to establish a stateful routing session based on the suitability of one or more candidate return path interfaces. This determination is typically made at the time a first packet for a new session arrives at the router on a given ingress interface. In some cases, the router may be configured to require that the ingress interface be used for the return path of the session, in which case the router may evaluate whether the ingress interface is suitable for the return path and may drop the session if the ingress interface is deemed by the router to be unsuitable for the return path. In other cases, the router may be configured to not require that the ingress interface be used for the return path, in which case the router may evaluate whether at least one interface is suitable for the return path and drop the session if no interface is deemed by the router to be suitable for the return path.

  • Patent number: 10999182
    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: 10432522
    Abstract: An intermediate node obtains a lead packet of a plurality of packets in a session having a unique session identifier, modifies the lead packet to identify at least the intermediate node and also to identify source and destination port numbers assigned by the intermediate node for a possible forward association, and then forwards the lead packet toward the destination node though an intermediate node electronic output interface to the IP network. The intermediate node also may receive, through an intermediate node electronic input interface in communication with the IP network, a backward message from a next node having a next node identifier. Both the intermediate node and the next node form an association between the intermediate node identifier, the next node identifier, and the source and destination port numbers assigned by the intermediate node. This association is part of a forward association for the intermediate node and is part of a return associate for the next node.

  • Patent number: 10432519
    Abstract: A packet routing method and apparatus for managing packets of a bi-directional session between a first node and a second node in an IP network receives a mid-stream packet at an intermediate node. The intermediate node is not part of the bi-directional session. Next, the method identifies the bi-directional session (“identified session”) from which the mid-stream packet originated. The identified session includes a bi-directional path between the first node and the second node, while the bi-directional path includes a plurality of nodes for bi-directionally forwarding packets between the first node and the second node. The method then directs that one or more packets of the identified session be routed to at least one of the plurality of nodes of the identified session.

  • Patent number: 10425511
    Abstract: A routing method checks a network path selected for transmitting a stream of packets between a first routing node and a second routing node in a computer network. The stream of packets complies with a first transport protocol. The method forwards, from the first routing node toward the second routing node, a set of handshake packets. The set of handshake packets includes change information indicating a change in the transport protocol for a plurality of the packets in the stream. The method modifies the plurality of packets in the stream (“modified packets”). Specifically, the method modifies the first transport protocol header in the plurality of packets in the stream to have a second transport protocol header of a second transport protocol. This modification preferably does not increase the packet size of each of modified packets.

  • Patent number: 10298616
    Abstract: An apparatus and/or method secures session communications between a first network (having a first encryption device configured to encrypt at least some session communications from the first network to the second network) and a second network. The apparatus and/or method receive, at the first network, given session packets of a given session between the first and second networks, and determine that at least one of the received given session packets is encrypted (“encrypted given session packet”). The given session involves a Layer 7 application that encrypted the at least one encrypted given session packet. Next, the apparatus and/or method controls, in response to determining that the given session packet is encrypted, the first encryption device to permit communication of the given session with the second network without further encrypting a plurality of the encrypted given session packets. Preferably, the first encryption device encrypts none of the given session packets.

  • Patent number: 10277506
    Abstract: A packet routing method for directing packets of a session in an IP network causes an intermediate node to obtain a lead packet of a plurality of packets in a given session. The intermediate node has an electronic interface in communication with the IP network and obtains the lead packet through that same interface. The method maintains, in a routing database, state information relating to a plurality of sessions in the IP network. Each session includes a single stateful session path formed by an ordered plurality of nodes in the IP network, and the state information includes information about the ordered plurality of nodes in the sessions. The method further accesses the routing database to determine the state of a plurality of sessions, and forms a stateful given path for packets of the given session across the IP network as a function of the state information in the routing database.
