Differentiated Service

Diffserv-aware and Traffic Engineering combine the advantages of MPLS, Traffic Engineering (TE) and Differentiated Services (Diffserv, DS) to provide high performance and Quality of Service(QoS) in networks. We have designed three scenarios on Juniper Networks platforms to analyze the packet loss rate and delay for video, voice and data. The results show that MPLS DS-TE can improve the QoS for differentiated service effectively. The research has practical value for the development of DS-TE based on MPLS.

Salient Features

When we call someone over the internet using a service such as Skype or Google talk, we may experience certain undesirable problems. For instance, we may not be able to hear the other person very well, or even worse, the call may be dropped. In order to eliminate these problems, the underlying IP network has to be able to provide quality of service guarantees. Several schemes have been developed that enable the IP network to provide such guarantees. Of these schemes, the multi-protocol label switching (MPLS) and the differentiated services (DiffServ) are the most widely used. In this chapter, some of the salient features of MPLS and DiffServ are reviewed.
