Mechanism for Per-Class QoS Monitoring in IP/MPLS Transport Networks

Overview

This paper presents a study on the usage of MPLS as the technology for transport networks which have to be sensitive to IP Differentiated Services. Advantages of MPLS for implementing Traffic Engineering and the capabilities that lead it towards integration with IP-DiffServ are discussed. Several solutions for DS-TE MPLS are exposed. On the other hand, a mechanism for monitoring classes of service per node in DS-TE MPLS networks is presented.
