  • System and method for router data distribution
    Patent number: 8335219
    Abstract: Employing an asymmetric protocol, multiple sources reliably broadcast dynamically changing routing tables incrementally across multiple consumers from a single distributor. Each of multiple sources send current tables to the distributor using a snapshot mechanism. Message are buffered, segmented, paced by timers, and broadcast to the consumers repetitively at the distributor. Negative acknowledgments from the consumer request missing messages from the distributor after receipt of a keepalive message from the distributor. The distributor marks the missing messages and retransmits replacements from a history buffer only after firing of a resend timer. A unique Session ID included in all messages originating from each particular source facilitates reliable table distribution from multiple sources to multiple consumers via a single distributor.
