The splitter intercepts a message packet in the network layer and modifies the network routing header and transport header of the message packet to form a modified message packet. The dispatcher receives modified message packets from the transport layer, recovers information from the message packets, passes the modified message packets back to the transport layer and adapts the transport layer to adapt communication dependent upon the information recovered from the message packets. The connections database stores the original source address, the original destination address, the original source port identifier and the original destination port identifier of an incoming message packet. A message packet is modified, with reference to the connections database, so that message packets from the first and second nodes are routed through the dispatcher. | 2009-03-05 |
