Abstract
Multiplexing of encrypted tunnels is facilitated by the use of a custom header. Upon receiving a packet, information about the packet is collected stored, such as a port number, destination instance identifier, and a hash key. A custom packet is generated that includes the encrypted packet and a custom header including some or all of the collected information. Middleware may retrieve information from the custom header to perform load balancing, routing, or other function. The destination instance may use information from the custom header to obtain the port number, which may be changed in the custom packet to accommodate limitations of the middleware.
