Abstract
A system for use with communications according to TCP, or a similar protocol, includes a sender host, one or more routers, and a destination host. Each router includes means for generating acknowledgement packets and translating addresses associated with data packets. When a data packet is received by a router, an acknowledgement packet is returned with a source address corresponding to the router and a destination address corresponding to the sender host. The sender host perceives the acknowledgement packet as having been sent by the destination host. As the acknowledgment packet is sent by the router, and not the destination packet is sent by the router, and not the destination host, this system allows acknowledgment packets to be received on a shorter timescale, reducing the effects of a link delay. Although the route between the sender host and the destination host is divided into multiple connections, the hosts perceive a single, conventional connection.
