What is MPLS?

MPLS (Multi Protocol Label Switching) technology-based package delivery that meets industry standards and is used to accelerate and facilitate the management of network traffic flows for higher QoS (Quality of Service), for example, provides time Real audio and video and meet the requirements of bandwidth, service level agreement (SLA).

The reason is that MPLS "Multi" is because that is compatible with asynchronous transport mode (ATM), Internet Protocol (IP)Frame Relay and network protocols.

In view of Open Systems Interconnection (OSI), MPLS allows most packets held on level 2 (switching) transferred layer on layer 3 (routing) level, although MPLS is out of the seven levels of the OSI model-the box as a forwarding Mechanisms are separated from their underlying data-link services.

The MPLS network is so versatile that technology can offer anything from IP VPNs to Metro Ethernet services overProvisioning optical performance.

Instead the router must "decide" where to send each bit or byte of information, through which he is, can delay MPLS and fragmentation of information through the assignment of any new package of online information, a FEC (Forwarding Equivalence Class wins a) Include a short "tag" or something identifiable information to the package.

Several labels are different FEC planned according to a table in each router runin a network.

This additional information eliminates the need for analysis and decision, the router must make a rule, and then accelerates and makes more organized information expressway (in volume in the Internet on a daily basis). Most of the major Internet Service Providers (ISPs) have already implemented the MPLS.

MPLS uses two types of routers in a network: Label Edge Router (governor) on the edge of the network to make peace andanalysis and calculations, the classification of packets before the packet enters the core network and the Label Switch Router (LSR), which rapidly analyze the FEC label and forwards the packet according to the manual.

Then the edge router at the receiving end remove the label from the package, so that, if translated only the original information as signals of a computer user.

MPLS is probably 3 based on Cisco Systems' Tag Switching LayerTechnology for use in Wide Area Networks (WAN) requires developed by many companies.
