MPLS Multi Protocol Label Switching

Means MPLS Multi Protocol Label Switching. It is a protocol rather than a specific type of service. It can be used to provide any type of circuit that the needs of customers, the DSL Optical connectivity.

Make better use of network paths and increase the speed of your Internet connection is one of the features of MPLS. It was formed by the Internet Engineering Task Force, or IETF. He used the same technology to make the current World Wide Web a better place. It is very important role to play in the management of large enterprises without coperate today. There are many previous technologies, such as frame relay and ATM sharing the same objective as MPLS, but they could not live up to the mark. MPLS is now himself keeping in mind the failures of the ATM. Some of these technologies are already replaced by MPLS. Although both MPLS and ATM to provide a connection orianted service for transporting data, the major difference is in the field of transport and means of encapsulation.

The best feature of MPLS is its ability to label data packets. In traditional IP networks, packets are routed based on data from the network layer header. The arrival of each packet to a router essentially forces to "decide" where it should go without regard to its actual content.

MPLS significantly accelerates the routing process by labeling each packet, it happens on the network. Each router stores information on how to handle different types of packages, as indicated by the head of their label. This directly translates into greater efficiency by reducing the load on the routers of the organization and free up resources. Speed packet transmission are increased by the load on the network infrastructure is reduced.

The advantages inherent in MPLS are most noticeable in situations where real-time traffic (voice, video) is set to be given preference over data packets that do not require the same amount of speed or priority such as electronic mail. In an IP network, all traffic is treated equally. This becomes a critical problem when demand for bandwidth to temporarily exceed the capacity of the circuit and the router starts to discard packets. Emails to receive the same network as a priority real-time video or audio conference, and often the result of telephone calls or video transmissions of inferior quality, as the two battle against one another priority. On the other hand, an MPLS network assigns high priority real-time voice and video. E-mail traffic and other links that are not as likely to be affected by the latency will be pushed to the back of a router's queue to make room for the movement of high priority, as MPLS offers different qualities of service (QoS) across the network. This significantly improves application performance in real time and has an imperceptible effect on lower priority, such as e-mail traffic, where delay in milliseconds is almost impossible to detect.

In a word, give your MPLS high priority, mission critical IP traffic priority to reach its destination without any interaction from you and without significant changes to your network infrastructure.
