Abstract

A system and method supporting efficient, scalable stateful switchover of transport layer connections in a telecommunications network element. One method involves receiving, at a network element comprising an active transport protocol process coupled to a standby protocol process, a request to configure a first transport layer connection maintained at the active transport protocol process for stateful switchover; receiving an event associated with the first transport layer connection; creating a message containing replicated event information based on the received event; sending the message to the standby transport protocol process; and processing the message at the standby transport protocol process, wherein the standby transport protocol process replicates state information for the first connection.

First claim

What is claimed is:

1. A network element comprising:
an active route processor coupled to a computer-readable storage medium storing one or more first sequences of instructions comprising active high availability process logic and active transport communications logic;
a standby route processor coupled to a second computer-readable storage medium storing one or more second sequences of instructions comprising standby high availability process logic and standby transport communic…
