Enhanced large data transmissions and catastrophic congestion avoidance over IPv6 TCP/IP networks

摘要

A system and method of reducing network congestion whereby significant improvement can be gained by the elimination of catastrophic network congestion failure within a TCP/IP network. Exemplary embodiments are implemented by an improved process for dealing with data loss related to IPv6 fragmentation, in which a ICMPv6 error message is transmitted by a destination node containing a bitmap of the unreceived datagram fragments. The sending node receives the error message and prepares only those unreceived fragments for transmission.
