Abstract
The present invention provides a new synchronization method named Multi-Node Echo Method (MNEM), which settles the problem of clock/data synchronization with asymmetrical channels. In MNEM, the echo messages are relayed among multi-node loop both by clockwise and anti-clockwise. Based on Multi-Node Echo Method, the invention further provides a method to detect symmetrical status of a communication network, a method to detect asymmetrical status of any channel in a communication network, and a method to calculate the sending and receiving delay values of any channel in a communication network, even when the channel is asymmetrical.
