A memory bandwidth control device is capable of significantly improving efficiency of data transfer between an external device and a memory. This invention provides a memory 80 used for temporarily storing and outputting data to be communicated with external devices being connected via input / output ports, and an I / O buffer 2 for dynamically assigning memory bandwidth to external devices requesting data transfer when receiving the data transfer requests from the external devices to the memory 80. As compared with a case of assigning fixed memory bandwidth, efficiency of data transfer to the memory 80 can be significantly improved without wasting memory bandwidth.

The invention discloses a transmission control protocol method for a satellite network, which is a control method for data transmission in a transport layer of the satellite network and is used for flow control and error control of transmission in the network so as to realize high-efficiency data transmission. The method is mainly used for improving congestion avoidance in congestion control through the following steps of: probing an optimal transmission window by dichotomous increase; and then differentiating a congestion error code by a prediction method for calculating the number of data packets being transmitted in the current network so as to effectively solve the problem of high error rate. Meanwhile, a selective acknowledgement (SACK) mechanism is adopted to only retransmit the discarded packets as much as possible when the packets are discarded so as to reduce the possibility of discarding a plurality of packets in primary window data transmitted at a high error rate and improve the utilization ratio of the network. The method can realize high-efficiency data transmission when used in the satellite network with high error rate and large time delay.
