Enhanced packet redirect capabilities are disclosed herein for draining traffic to a server. In an implementation, a server in an infrastructure service receives a packet from a stateless load balancer. The packet may comprise a request for content. A user space program on the server determines whether a connection identified in the packet belongs to the server. If the connection belongs to the server, the user space program handles the request for the content. If not, the server forwards the packet to a secondary server in the infrastructure service. The secondary server, to which the connection may belong, can then handle the request.

User space redirect of packet traffic

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.

Fast reroute for connections over outbound paths
