Multiprotocol Label Switching


(MPLS) A ref="module.php?name=Lexikon&file=search&eid=1&query=packet switching">packet switching ref="module.php?name=Lexikon&file=search&eid=1&query=protocol">protocol developed by the ref="module.php?name=Lexikon&file=search&eid=1&query=IETF">IETF. Initially developed to improve switching speed, other benefits are now seen as being more important. MPLS adds a 32-ref="module.php?name=Lexikon&file=search&eid=1&query=bit">bit label to each ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet to improve ref="module.php?name=Lexikon&file=search&eid=1&query=network">network efficiency and to enable ref="module.php?name=Lexikon&file=search&eid=1&query=routers">routers to direct ref="module.php?name=Lexikon&file=search&eid=1&query=packets">packets along predefined routes in accordance with the required ref="module.php?name=Lexikon&file=search&eid=1&query=quality of service">quality of service. The label is added when the ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet enters the MPLS ref="module.php?name=Lexikon&file=search&eid=1&query=network">network, and is based on an analysis of the ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet ref="module.php?name=Lexikon&file=search&eid=1&query=header">header. The label contains information on the route along which the ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet may travel, and the ref="module.php?name=Lexikon&file=search&eid=1&query=forwarding equivalence class">forwarding equivalence class (FEC) of the ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet. Packets with the same ref="module.php?name=Lexikon&file=search&eid=1&query=FEC">FEC are routed through the ref="module.php?name=Lexikon&file=search&eid=1&query=network">network in the same way. Routers make forwarding decisions based purely on the contents of the label. This simplifies the work done by the ref="module.php?name=Lexikon&file=search&eid=1&query=router">router, leading to an increase in speed. At each ref="module.php?name=Lexikon&file=search&eid=1&query=router">router, the label is replaced with a new label, which tells the next ref="module.php?name=Lexikon&file=search&eid=1&query=router">router how to forward the ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet. The label is removed when the ref="module.php?name=Lexikon&file=search&eid=1&query=packet">packet leaves the MPLS ref="module.php?name=Lexikon&file=search&eid=1&query=network">network. Modern ref="module.php?name=Lexikon&file=search&eid=1&query=ASIC">ASIC-based routers can look up routes fast enough to make the speed increase less important. However, MPLS still has some benefits. The use of ref="module.php?name=Lexikon&file=search&eid=1&query=FEC">FECs allows ref="module.php?name=Lexikon&file=search&eid=1&query=QoS">QoS levels to be guaranteed, and MPLS allows ref="module.php?name=Lexikon&file=search&eid=1&query=IP">IP ref="module.php?name=Lexikon&file=search&eid=1&query=tunnel">tunnels to be created through a ref="module.php?name=Lexikon&file=search&eid=1&query=network">network, so that ref="module.php?name=Lexikon&file=search&eid=1&query=VPN">VPNs can be implemented without ref="module.php?name=Lexikon&file=search&eid=1&query=encryption">encryption. ref="http://www.mplsrc.com/">MPLS Resource Center .
