Abstract
Systems and methods are provided to enable packets of network traffic to be routed to a network appliance. Bidirectional flows of network traffic can be routed to the same network appliance based on flow information of the corresponding packets. A network device may intercept the packet corresponding to a first flow and route the packet to a specific network appliance based on the first flow information. The network device may generate a direction agnostic tuple value based on data groups of the first flow information. The network device may propagate the direction agnostic tuple value across availability zones to a second network device in a different availability zone to store the direction agnostic tuple value for use for subsequent packets. The second network device can receive a second packet and transmit the second packet to the same network appliance based on the direction agnostic tuple value.
