Abstract: In this paper implementation of the Class Based Tunnel Selection(CBTS) in MPLS network using TE is discussed. The objective of TE in MPLS network is to alternate data path link when the network is congested. It also provides the combination of ATM’s (Asynchronous Transfer Mode) TE capabilities along with CoS (Class Of Service)at layer 2.5 to reduce latency and hence speed is improved. Traffic Engineering (TE) in MPLS network using tunnel for transmission of data packets. RSVP protocol is being used for reserving bandwidth along the path from source to destination. Here a CBTS mechanism is used to reroute sensitive traffic based on the priority of the customer through tunnels. The tunnel formation along the LSP (Label Switch Path) for forwarding packets is simulated using GNS3 tool. The simulation result shows that the round trip time of tunnel1(high priority) with packet size of 8000 bytes takes 439milliseconds which is faster than tunnel2(medium priority) with packet size of 8000bytes.It also reroutr sensitive traffic in real time which is used in voice and data world for transmitting information.
