Facilitating communication of routing information

摘要

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.

1. A method comprising:
receiving, at a shim, a plurality of incoming messages communicating routing information describing routes of an external region from a first protocol point of one or more protocol points, the one or more protocol points operating according to a routing protocol, the shim belonging to an internal region separate from the external region, a transport layer disposed between the shim and the one or more protocol points; processing and sending the incoming messages to a plurality of siblings, the siblings belonging to the internal region and at least one sibling located on a device separate from the shim, each sibling implementing a state machine for the routing protocol; receiving a plurality of outgoing messages from a first sibling; and processing and sending the outgoing messages to a second protocol point of the one or more protocol points.
