Enhanced error control communication systems and methods

The invention claims a retransmission method and system for new error detection method, and device. The processing capable of the middle information ring between two terminal line, the middle link via satellite. The, or time and detecting retransmission error control mechanism between the frame for network layer and data - link layer and output or being damaged in network layer. The invention claims a discovering to know and control protocol the process of terminal. Error the control processes' characteristics of comprises a view is connected to the conducting delay limit for business quantity type or the type of custom-made.
