PTN网络中基于Diff-Serv TE的QoS研究
QoS Research Based on Diff-Serv TE in PTN Network
摘要
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 (FTN) 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 .关键词
