Systems and methods to cache packet steering decisions for a cluster of load balancers
Abstract:
The present disclosure is directed towards methods and systems for caching packet steering sessions for steering data packets between intermediary devices of a cluster of intermediary devices intermediary to a client and a plurality of servers. A first intermediary device receives a first data packet and determines, from a hash of a tuple of the first packet, a second intermediary device to which to steer the first packet. The first device stores, to a session for storing packet steering information, the identity of the second device and the tuple. The first device receives a second packet having a corresponding tuple that matches the tuple of the first packet and determines, based on a lookup for the session using the tuple of the second packet, that the second device is the intermediary device to which to steer the second packet. The first device steers the second packet to the second device.
