Abstract
The present invention includes an intelligent router and method for improving the routing of datagrams, resulting in increased effective bandwidth over networks of high latency. The intelligent router can be used alone or in combination with a second intelligent router. An intelligent router buffers data bound for a destination node within the router itself until the destination node has available space. In addition, the intelligent router of the present invention may continue to transmit a datagram without waiting for confirmation of receipt of a previous datagram. Also, retransmission requests can be ignored until a later time to accommodate for the delay in the network. When using multiple intelligent routers communicating with each other, only the erroneous portions of individual datagrams need to be resent. Routing between two intelligent routers eliminate or reduces the transmission of redundant data being sent.
