Network protocol processing system and network protocol processing method

摘要

In a network protocol processing system in which variables of each of TCP transmission processing and TCP reception processing depend on each other, asynchronous parallel processing is realized between a transmission processing block and a reception processing block for updated protocol processing. Specifically, the system includes a high priority queue for transferring control data to be processed with high priority, a low priority queue for control data other than the above control data, and priority control means for distributing the control data to two kinds of queues. When a request for session establishment and the session disconnection of a new TCP session is issued from an application during transmission of TCP data, data related with the session establishment and the session disconnection is notified preferentially through the high priority queue, and other control data is transferred through the low priority queue.
