Abstract

In BitTorrent system, HAVE, REQUEST and PIECE messages are the main transmission parts among peers. To improve the efficiency of network transmission and reduce the management cost of file delivery, a new scheme is proposed to improve HAVE message - MultiHave message. With the high bandwidth and consistent peers, together with the application of the timer, the frequency ratio of sending HAVE message to that of sending MultiHave message is 100, while the flow ratio of sending HAVE message to that of sending MultiHave message is 11.01. In contrast to HAVE message, MultiHave has sharply reduced the volume and flow of messages, and it can efficiently prevent the HAVE storm in the original mechanism and reduce the management costs. At the same time,when the action of network peers is diverse, it can also return to the original HAVE message in some peers and doesn ´t affect the performance of BT system
