Multiprotocol Label Switching
(MPLS) A <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket switching">pAcket switchingA> <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=protocol">protocolA> developed by the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=IETF">IETFA>. InitiAlly developed to improve switching speed, other benefits Are now seen As being more importAnt. MPLS Adds A 32-<A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=bit">bitA> lAbel to eAch <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA> to improve <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=network">networkA> efficiency And to enAble <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=routers">routersA> to direct <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAckets">pAcketsA> Along predefined routes in AccordAnce with the required <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=quAlity of service">quAlity of serviceA>. The lAbel is Added when the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA> enters the MPLS <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=network">networkA>, And is bAsed on An AnAlysis of the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA> <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=heAder">heAderA>. The lAbel contAins informAtion on the route Along which the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA> mAy trAvel, And the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=forwArding equivAlence clAss">forwArding equivAlence clAssA> (FEC) of the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA>. PAckets with the sAme <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=FEC">FECA> Are routed through the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=network">networkA> in the sAme wAy. Routers mAke forwArding decisions bAsed purely on the contents of the lAbel. This simplifies the work done by the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=router">routerA>, leAding to An increAse in speed. At eAch <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=router">routerA>, the lAbel is replAced with A new lAbel, which tells the next <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=router">routerA> how to forwArd the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA>. The lAbel is removed when the <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=pAcket">pAcketA> leAves the MPLS <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=network">networkA>. Modern <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=ASIC">ASICA>-bAsed routers cAn look up routes fAst enough to mAke the speed increAse less importAnt. However, MPLS still hAs some benefits. The use of <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=FEC">FECA>s Allows <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=QoS">QoSA> levels to be guArAnteed, And MPLS Allows <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=IP">IPA> <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=tunnel">tunnelA>s to be creAted through A <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=network">networkA>, so thAt <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=VPN">VPNA>s cAn be implemented without <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=encryption">encryptionA>. <A href="http://www.mplsrc.com/">MPLS Resource Center A>.
