Abstract
Some embodiments set forth a control message header rewriting methodology. Incoming packets are inspected to identify control messages. Each control message is then inspected to determine whether it originates from a client engaged in a session with a server or from an intermediary node along the path connecting the client and the server. The determination is predicated on a comparison of the addressing provided in the control message header and the addressing provided in the offending packet header, wherein the offending packet is the packet that triggers the intermediary node to issue the control message. If the addressing differs, the header addressing of control message is rewritten using the header addressing of the offending packet. Otherwise, a session table lookup is performed to identify which session the control message is directed to based in part on a hash of the control message header addressing.
