摘要:
在电信业务IP化趋势推动下,传送网承载的业务从以TDM为主向以IP为主转变。分组传送网(PTN)正是IP/MPLS,以太网和传送网3种技术相结合的适合分组传送的下一代传送网技术。在当前的T-MPLS、PBT二种主流的PTN技术中,T-MPLS在标准化过程中抢得先机,较为成熟。IP网络对服务质量(QoS)的支持一直是网络技术研究的热点,有几种协议支持IP网络的QoS。文中描述了综合服务结构模型(IntServ/RSVP)、区分服务结构模型(Diff-Serv)和MPLS TE的原理,分析了Diff-Serv TE的技术原理并提出了基于T-MPLS Diff-Serv TE实现多种业务服务质量保证的方案
Abstract:
Driven by the IP-based trend of telecommunication traffic,traffic carried by transport network changes from TDM-based to IP-based.Combining three technologies including IP / MPLS,Ethernet and transport network,packet transport network(PTN) is next-generation transport network technology which is proper to packet transport.In the current three PTN technologies including T-MPLS,PBB-TE,PVT,T-MPLS seize the initiative in the standardization process and is more mature.IP network supports Quality of Service(QoS) has been a hot research of network technology.There are several protocols to support IP network QoS.Describe the Integrated Services model(IntServ / RSVP),Differentiated Services model(Diff-Serv) and MPLS TE,and then analyze the technology principle of Diff-Serv TE and propose an implementation of technology to support data transmission QoS based on T-MPLS Diff-Serv TE
