US Patent 7292571 Load balancing with direct terminal response

Generally, a terminal can access a resource selection device to access a content source, the content source being structured and arranged to respond directly to the terminal. For example, a PC (“personal computer”) may be pointed at a load-balancing switch. The load balancing switch translates the PC's traffic and directs the PC traffic to a server (or switch) providing streaming services. The server responds directly to the terminal, but uses the IP address/identity of the load-balancing switch with which the terminal is communicating.
