  • Publication number: 20170346709
    Abstract: In exemplary embodiments of the present invention, special metadata is added to link monitoring protocol messages exchanged by pairs of adjacent nodes to allow such nodes to detect communication link failures and determine whether the failure affects an incoming communication link or an outgoing communication link. The link monitoring protocol messages may be augmented BFD messages.

  • Publication number: 20170339194
    Abstract: A method of routing data across a network receives a session request from a client node to access at least one node in a local network having a plurality of nodes. The method also receives a client certificate (e.g., a digital certificate at least partially specified by known standards, such as the “X509 Standard”) from the client node. The client certificate has client information specifying at least one node to receive packets from the client node. Next, the method uses the client certificate to execute an authentication process. If the authentication process authenticates the client node, then the method routes data packets from the client node to at least one node in the local network as specified by the client information in the client certificate.

  • Publication number: 20170339061
    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 then forwards the lead packet toward the destination node though an intermediate node electronic output interface to the IP network. The intermediate node also receives, 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. The backward message includes the next node identifier and the session identifier. The intermediate node forms an association between the next node identifier and the session identifier, stores the association in memory to maintain state information for the session, and obtains (e.g., receives) additional packets of the session. Substantially all of the additional packets in the session are forwarded toward the next node using the stored association.

  • Patent number: 9762485
    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.

  • Publication number: 20170250906
    Abstract: An advanced routing system and protocol (referred to herein as “Route Exchange” or “REX”) hides familiar IPv4 and IPv6 addresses and replaces traditional routing logic with words and relationships between named elements. Among other things, this makes IP routing tables significantly easier to understand. In addition, a single routing scheme can be used for any combination of private networks, public networks, IPv4 addressing models, and IPv6 addressing models. Underneath the words lie real IP addresses that move the packets from place to place. These routing addresses abstract away the underlying network.

  • Patent number: 9729682
    Abstract: A method processes a session having a first session packet received by a current node in an IP network having a plurality of nodes. The plurality of nodes includes a next node, and the current node that communicates with the next node using a Layer 3 protocol. The method receives the first session packet, which has a digital signature, payload data, and meta-data, at the current node. The method uses the payload data and meta-data to produce validation information, and uses the digital signature to produce a comparator digital signature. Next, the method compares the validation information with the comparator digital signature. If the validation information does not match the comparator digital signature, then the method discards the first session packet. If there is a match, then the method digitally signs the first session packet, and routes the first session packet to the next node via the IP network.

  • Publication number: 20160164780
    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.

  • Patent number: 8767715
    Abstract: Systems and methods of establishing IP telephony sessions between enterprises are disclosed. A first enterprise requests an association with a second enterprise. Both enterprises and the second enterprise belong to the same federation. The association request is accepted, to establish an association between the first and second enterprises. In response to the acceptance, a direct routed path is established between the first enterprise and the second enterprise. One of the associated enterprises requests activation of an IP telephony service. If the request to activate references the association, an IP telephony session is established using the direct routed path.
