Protection Methods in Traffic Engineering MPLS Networks

The objective of this project was to perform a theoretical review of Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) technology and traffic protection methods in the Traffic Engineering on MPLS networks and implement traffic protection in an ISP’s (Internet Service Provider’s) network.\n\nThe project was carried out first by introducing VPN (Virtual Private Network) and its different categories and modes. VPN is closely related to MPLS. The MPLS-TE was introduced and its operations and protocols. Traffic Protection methods and schemes were also explained in depth. In particular, the focus was on link protection and the different schemes used for local protection. The link protection using FRR (Fast Rerouting) with 1:1 scheme was configured on an ISP network. Testing was done before and after a link failure. \n\nThe results from the implementation show that the traffic protection can be used to support the ISP’s network failure from affecting the customer’s traffic. This can be used to improve the reliability of the ISP’s network and reduce delays and communication failure caused by network failures.
