A MPLS Traffic Engineering-based Route Selecting Mechanism

By the analysis of why and how the phenomena of oscillation to be happened in traditional IP QoS routing, the new concepts of call level QoS routing and packet level QoS routing as well as the Multi-Label QoS Routing (MLR) mechanism are proposed. As a mechanism of packet level QoS routing, the MPLS, it can overcome the oscillation theoretically, and also improve the overall network performance and network resource utilization rate as well. The experiment results of simulation are achieved by simultaneously running the real-time and non-real-time traffic.
