Abstract
A server detects a failure of an outbound path based on at least a measure of forward progress made on a connection between the server and an end point. In response to the failure, the server generates a hash value based at least on an identifying value of the connection and a failure counter associated with the measure of forward progress made on the connection. The server then selects a next outbound path for the packet flow based on at least the hash value generated in response to the failure. The server also sends the packet flow over the next outbound path to the end point.
