A Traffic Engineering Algorithm Supporting QoS in MPLS Networks

摘要: 該文提出了一種改善QoS的隊(duì)列調(diào)諧算法(Queue Tuning Algorithm:QTA),該算法應(yīng)用于多協(xié)議標(biāo)簽交換(MPLS)流量工程.該算法通過把不同類別的業(yè)務(wù),如傳統(tǒng)的盡力而為(Best-Effort)業(yè)務(wù)和具有QoS需求的業(yè)務(wù),映射到不同隊(duì)列,然后根據(jù)鏈路的狀況以及業(yè)務(wù)的QoS需求來進(jìn)行隊(duì)列調(diào)諧.QTA在實(shí)現(xiàn)負(fù)載均衡的同時(shí)又支持業(yè)務(wù)流的QoS,優(yōu)化網(wǎng)絡(luò)資源的利用.仿真表明該算法在MPLS網(wǎng)絡(luò)中運(yùn)行良好.
