Abstract

See full text

Example methods and computer systems for packet handling for active-active stateful service insertion are disclosed. One example may involve in response to detecting a first packet from a first active logical service router (SR), a computer system generating and storing state information that associates (a) the first active logical SR and (b) first tuple information specified by the first packet. The first active logical SR and a second active logical SR may be both associated with the service endpoint address and configured to operate in an active-active mode. In response to detecting the second packet from a destination responsive to the first packet, the computer system may select the first active logical SR over the second active logical SR based on the state information and second tuple information specified by the second packet; and send the second packet towards the first active logical SR for processing according to a stateful service.
