英文摘要	Optical burst switching (OBS) is thought to be the best way to adapt the bursty IP traffic over optical wavelength division multiplexing (WDM) networks. OBS technology facilitates the efficient integration of both IP and WDM, and it provides statistical multiplexing gains and avoids long end to end setup time of traditional virtual circuit configuration. However, burst contention is inescapable in OBS for connectionless transmission and the absence of optical random-access memory. So many contention resolution methods are proposed. In this paper, a novel decrease contention scheme--IP calking was proposed for optical burst switched networks. IF calking method uses IP packets to carry single-hop traffic and the burst to carry multihop traffic as well, filling gaps between bursts by stuffing IP packets between adjacent nodes. A statistical analysis model was developed to analyze the performance of this method. In an arbitrary network, the analyses indicate that the decrease of packet dropping probability is directly proportional to the link number and almost inversely proportional to the square of the node number. The theoretical results are validated through extensive simulations. Simulation results show that IP calking decreases about 50 % data drop probability of the no calking scheme and the link utilization is improved 5 similar to 25% which varying with the offered load in a simple network.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000253397500037&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Optics; Telecommunications; EI; CPCI-S(ISTP); 0
