  • Facilitating communication of routing information
    Patent number: 8755393
    Abstract: In certain embodiments, facilitating communication of routing information includes receiving, at a shim, incoming messages communicating routing information from a first protocol point of one or more protocol points operating according to a routing protocol. The shim belongs to an internal region separate from an external region, and a transport layer is disposed between the shim and the protocol points. The incoming messages are processed and sent to siblings that belong to the internal region. Each sibling implements a state machine for the routing protocol. Outgoing messages are received from a first sibling. The outgoing messages are processed and sent to a second protocol point of the one or more protocol points.
