【摘要】：P2P流量已成為網(wǎng)絡(luò)中的主要流量,但現(xiàn)有EPON系統(tǒng)不能很好的承載本地P2P業(yè)務(wù)。文中從MPCP協(xié)議的角度對(duì)邏輯鏈路標(biāo)簽及其過濾規(guī)則進(jìn)行擴(kuò)展,使本地P2P數(shù)據(jù)包不需經(jīng)OLT端二層交換即可實(shí)現(xiàn)下行轉(zhuǎn)發(fā),從而大大改善了P2P業(yè)務(wù)的QoS。并以此方案為基礎(chǔ),提出改進(jìn)EPON的DBA算法,設(shè)置專門的P2P時(shí)隙,實(shí)現(xiàn)P2P業(yè)務(wù)的全光域轉(zhuǎn)發(fā)。兩種方案的建模仿真結(jié)果表明,兩者均能明顯改善EPON對(duì)本地P2P業(yè)務(wù)的承載能力。
[Abstract]:P2P traffic has become the main traffic in the network, but the existing EPON system can not carry the local P2P services well. In this paper, the logical link label and its filtering rules are extended from the point of view of MPCP protocol, so that the local P2P packets can be transmitted downlink without the need of OLT two-layer switching, thus greatly improving the QoS. of P2P services. On the basis of this scheme, an improved DBA algorithm of EPON is proposed, and a special P2P time slot is set up to realize the all-optical forwarding of P2P services. The modeling and simulation results of the two schemes show that both schemes can obviously improve the bearing capacity of EPON to local P2P services.
