Performance evaluation of smart grid communication network using MPLS

The power grid integrates multiprotocol label switching (MPLS) technologies into existing backbone communication networks present between substations and control centers. MPLS is an emerging technology for smart grid communication networks. MPLS uses labels to identify the packets. This paper proposes path protection using MPLS traffic engineering for IEEE 30 bus system communication network for smart grid. Resiliency is achieved by means of end-to-end restoration capabilities that enable the network to reroute the path around a failure. The proposed approach is validated using OPNET.
