Ensuring that the network runs at optimal precision with data remaining accurate, traveling fast, and to the correct user are the main objectives of QoS. The various media that fly across the network including voice, video, and data have different idiosyncrasies that try the dimensions of the network. This malleable network architecture poses an always moving potential problem for the network professional.The authors have provided a comprehensive treatise on this subje 410 4$aThe Morgan Kaufmann Series in Networking 606 $aComputer networks$xQuality control 606 $aComputer networks$xReliability 606 $aIntegrated services digital networks$xQuality control 606 $aMPLS standard 606 $aMulticasting (Computer networks) 615 0$aComputer networks$xQuality control. 615 0$aComputer networks$xReliability. 615 0$aIntegrated services digital networks$xQuality control. 615 0$aMPLS standard. 615 0$aMulticasting (Computer networks) 676 $a004.6 700 $aEvans$b John$c(Engineer)$0386732 701 $aFilsfils$b Clarence$01700753 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910822796803321 996 $aDeploying IP and MPLS QoS for multiservice networks$94083986 997 $aUNINA
