區(qū)分服務(wù)中一種TCP友好的公平數(shù)據(jù)包標(biāo)記算法
A TCP-Friendly Fair Packet Marking Algorithm in DiffServ
-
摘要: 在DiffServ網(wǎng)絡(luò)中,存在一些對(duì)帶寬利用的不公平性。為了解決這些不公平性,該文提出了一種基于TSW的標(biāo)記算法,稱之為T(mén)CP友好的公平數(shù)據(jù)包標(biāo)記算法,它能以一種近似按比例的方式在各個(gè)匯聚流之間公平地分配網(wǎng)絡(luò)中的剩余帶寬,同時(shí)還能在匯聚流內(nèi)部對(duì)TCP流和UDP流進(jìn)行公平的帶寬分配。通過(guò)仿真試驗(yàn)對(duì)算法進(jìn)行了驗(yàn)證,并與其它幾種標(biāo)記算法進(jìn)行比較,結(jié)果證實(shí)本算法比其它幾種算法具有更好的公平性。

Abstract: Researchers found unfairness in DifFServ network, to solve this problem, a TSW-based marker is proposed, which is called TCP-friendly Fair Packet Marking algo-rithm(TFPlV[). With this marker, proportional fair sharing of excess bandwidth among ag gregate can be achieved, and so the better fairness between TCP and UDP flows in an aggregate. The validation of this marking algorithm through simulation experimentation is made, and the simulation result is compared with some other marking algorithms, which verifies that the TFPM algorithm has better fairness than other algorithms. -
