Abstract
Two or more network traffic processors connected with the same LAN and WAN are identified as neighbors. Neighboring network traffic processors cooperate to overcome asymmetric routing, thereby ensuring that related sequences of network traffic are processed by the same network proxy. A network proxy can be included in a network traffic processor or as a standalone unit. A network traffic processor that intercepts a new connection initiation by a client assigns a network proxy to handle all messages associated with that connection. The network traffic processor conveys connection information to neighboring network traffic processors. The neighboring network traffic processors use the connection information to redirect network traffic associated with the connection to the assigned network proxy, thereby overcoming the effects of asymmetric routing. The assigned network proxy handles redirected network traffic in much the same way that it would handle network traffic received directly.
