Abstract

The invention discloses a transmission system of grid-oriental configurable data which solves the problems of insufficient reliability existing in the prior protocol and high spending of the system operation. The invention comprises the following processes: data communication connection is built between two parties of the communication with a mode of three times handshake; when a fault occurs, the linkage of permanent connection is closed; a receiving and sending synchronization and a flow controlling of the information are carried out by a sliding window; in the data transmission protocol, an authentication technology is adopted for assuring the reliable transmission of the data. The invention, through the receiving and sending synchronization and the flow controlling of the information carried out by the sliding window, achieves function of stabilizing the rate, resending the lost packet and transmitting in sequence. The protocol realizes flow controlling. When the receiver has a value which increases to a right value in the receiving window, the receiver then sends a window notice to the sender under the condition of that the receiving window can be zero for a longer time in a large flow. Through effective controlling carried out for controlling a sending rate of the sender, the phenomenon of occurrence of an over congestion in the network in big flow can be avoided.
