COOPERATIVE TCP / BGP WINDOW MANAGEMENT FOR STATEFUL SWITCHOVER |
摘要 |
A system and method for performing stateful switchover with reduced data, such as only metadata about a TCP window state. The metadata comprises a size of TCP packets used to send BGP messages, and which of those have been acknowledged by a neighbor networking device. The networking device comprises a BGP module to establish a BGP session between the networking device and a neighbor networking device. An active transport module within the networking device synchronizes with a standby transport module within the networking device by sending the metadata. A fault detector within the networking device initiates a stateful switchover from the active transport module to the standby transport module responsive to detecting a failure of a process and/or processor. The standby transport module uses the metadata to determine stateful metadata for preserving current BGP and TCP sessions of the networking device.
