Abstract:
1. A control method of a communication system, comprising: dividing a primary packet of an Internet Protocol (IP) output from a first information processor at a transmitting side into a plurality of secondary packets of said IP in a first communication controller at said transmitting side; sending said plurality of secondary packets to a network by said first communication controller; receiving said plurality of secondary packets in a second communication controller at a receiving side; generating, in said second communication controller, a reassembly header with an IP header and a Transmission Control Protocol (TCP) header for processing said primary packet to be reassembled, where said generating is performed by: sending said reassembly header from said second communication controller to a second information processor at said receiving side; executing, at said second information processor, protocol processing that includes analyzing said reassembly header to analyze the contents of said IP and TCP headers included in said reassembly header; temporarily storing a result of said protocol processing in said second information processor; reassembling said plurality of secondary packets into said primary packet in said second communication controller in parallel with said executing; upon completion of said reassembling, sending said reassembled primary packet from said second communication controller to said second information processor and allowing, at said second information processor, said temporarily stored result of said protocol processing to be reflected in a status of said protocol processing, wherein said protocol processing includes:
