Abstract
A method of transferring application layer network information comprises the computer-implemented steps of electronically transferring, from a first electronic digital data processor to a second electronic digital data processor, one or more transport layer connections associated with one or more application layer sessions; creating and sending, to the second processor, one or more application layer messages that appear to initiate a new application session with a peer; creating and sending, to the second processor, one or more application update messages that transfer application data from the first processor to the second processor; repeating the creating and sending steps for all application layer sessions that are active at the first processor. One embodiment provides stateful switchover of BGP sessions when one BGP host in a redundant system restarts asynchronously with respect to another host, without problems associated with bulk transfer of BGP route information.
