What is Multiprotocol Label Switching (MPLS)

Encyclopedia of Information Science and Technology, Third Edition
a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table.

This article is addressed to network engineers and managers of large enterprises that are interested in energy consumption of network devices. In the last years many efforts in telecommunications network research and design have been devoted to reduce energy consumption of network devices. Development of green routers aimed at saving energy when the input traffic is low is receiving increasing attention in the scientific community. In this article we face the problem of further reducing power consumption in transport networks adopting the Fast Reroute technique together with a low power idle approach, which result in substantial energy saving when the traffic on the network is low. We have run simulations using NS-2 and as test case, we developed the proposed approach on top of the NetFPGA architecture and results are very promising for larger exploitation.

Network Optimization Using Evolutionary Algorithms in Multicast Transmission
MPLS integrates the label switching forwarding paradigm with network layer routing. MPLS is an approach to packet forwarding whereby short fixed length labels are attached to IP packets by a LSR at the ingress to an MPLS domain. An ingress LSR attaches labels to packets based on the concept of forwarding equivalence classes (FEC), so that packets that belong to the same FEC are assigned the same label value and follow the same LSP.
