  6. MPLS is best summarized as a Layer 2.5 networking protocol. In the traditional OSI model:  Layer 2 covers protocols like Ethernet and SONET, which can carry IP packets, but only over simple LANs or point-to-point WANs.  Layer 3 covers Internet-wide addressing and routing using IP protocols

MPLS and Traffic Eng allows for one to spread the traffic and distribute it across the entire network infrastructure like magnetic fields between poles while also providing the redundancy required for high availability service MPLS is primarily used in two ways: to perform traffic engineering in IP networks, providing greater determinism and more efficient usage of network resources; and for enabling MPLS based L2 or L3 enterprise V irtual Private Network (VPN) services, which continue s to be one of more profitable services offered by ISPs 3 12.

MPLS Traffic Engineering (TE) Traffic engineering refers to the process of selecting LS paths chosen by data traffic in order to balance the load on various links, routers, and switches in the network. This is most important in networks where multiple parallel or alternate paths are available MPLS Traffic Engineering (MPLS TE) is a growing implementation in today's service provider networks. MPLS adoption in service provider networks has increased manifold due to its inherent TE capabilities. This chapter provides you with information on the operation and configuration of MPLS TE on Cisco routers

One of the applications of Multiprotocol Label Switching (MPLS) is Traffic Engineering (TE), which is used for manipulating traffic to fit a particular network. TE is important for service providers to efficiently use their backbones and provide high resiliency Some MPLS Benefits Traffic Engineering Traffic Engineering - the ability to set the path traffic will take through the network, and the ability to set performance characteristics for a class of traffic VPNs - VPNs - using MPLS, service providers can create IP tunnels throughout their network, without the need for encryption or end-user applications Layer 2 Transport Layer 2 Transport - New.

MPLS traffic engineering routes traffic flows across a network based on the resources the traffic flow requires and the resources available in the network.

Traffic Engineering • Institute of Transportation Engineers (ITE) • Traffic engineering is that phase of transportation engineering which deals with the planning, geometric design and traffic operations of roads, streets, and highways, their networks, terminals, abutting lands, and relationships with other modes of transportation infrastructure for any client traffic type. With the growth of packet-based services, operators are transforming their network infrastructures while looking at reducing capital and operational expenditures. In this context, a new technology is emerging: a transport profile of Multi-Protocol Label Switching called MPLS-TP

MPLS Labels • MPLS technology is intended to be used anywhere regardless of Layer 1 media and Layer 2 protocol. • MPLS uses a 32-bit label field that is inserted between Layer 2 and Layer 3 headers (frame-mode MPLS). • MPLS over ATM uses the ATM header as the label (cell-mode MPLS) [Latency inflation with MPLS-based traffic engineering, IMC 2011] Explain MPLS and tunnels.

The true advantages of MPLS and the reason for current interest in MPLS, however, lie not in the potential increases in switching speeds, but rather in the new traffic management capabilities that MPLS enables.
