The controller performs the management based on the control frame received from the gateway. The network transfers the data frame received from the gateway to a destination communication device without through the controller.

Abstract: 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.

The communication system includes a group of switches which process a received packet(s) by referring to a flow entry that defines processing content to be applied to the packet(s) and a controller that controls the group of switches. The controller comprises a topology detection unit that detects a network topology composed of a link(s) satisfying predetermined transmission quality from among links connecting respective ones of the switches, based on information obtained from the group of switches.

Abstract: A packet retransmission control system has: a network control block configured to perform packet retransmission control in an upper layer; and a packet retransmission control block configured to perform packet retransmission control with a shorter retransmission timeout than the upper layer in a lower layer that is lower than the upper layer. If the network control block receives a duplicate acknowledge packet being an acknowledge packet notifying a same sequence number for a predetermined number of times, the network control block performs packet retransmission. The packet retransmission control block determines whether or not retransmission of a same packet is performed earlier in the upper layer than in the lower layer. If retransmission of the same packet is performed earlier in the upper layer than in the lower layer, the packet retransmission control block prohibits retransmission of the same packet in the lower layer.
