Abstract


In order to evaluate the network end-to-end system performance , network one-way delay measurement of performance parameters is essential . However, due to the host of the network clock is not synchronized , the one-way delay the measure of value is difficult to accurately measure . To this end , the paper studies and designs to achieve a network host -oriented one-way delay measurement multi-master clock synchronization system , the system is based on the model of the ring topology . Ie : when the stamp on each host in a logical ring topology packet data measurement and statistics , and clock synchronization model , and ring topology further collaboration with node synchronization . First , the system study node synchronization model reference Paxson, Moon and Li Zhang proposed clock synchronization method based on the improved design proposed AV synchronization method , to provide users with accurate high-precision synchronization of timestamps . Secondly , based on the research base of the existing tree, star , or P2P the synchronous mesh topology system proposed the the cyclic synchronization topology synchronization system design . The system after the establishment of the synchronous model in the junction point between the use of logic annular synchronization topology , the computation of the synchronizing clock ring on the accumulated error , the synergistic correction of the synchronization model for each node in the ring , in order to further improve the synchronization precision . Finally, the system provides dynamic ring logical topology establishment , release and self-maintenance . Shorter convergence time to establish independent , lifted its ring logical topology . Also provide self- maintenance capabilities of the synchronization topology ring , and that the subsequent node can join the established synchronization ring node on the ring initiative to evacuate synchronizer ring , synchronizer rings in synchronization If the judging ring on the failed node will the synchronization node passive evacuation synchronizer ring current . In summary , the system can be in the same logical ring topology host node clock synchronization , this value to provide an accurate time stamp data for measuring the network each host one-way delay .
