Therefore, the reliability of a network as well as the satisfaction of its users relies largely on Quality of Service (QoS). Service quality through resource management in IP networks will ensure that sufficient resources are available to fulfil the delay of applications and packet loss requirements.This year several books on QoS from the angle of operators/engineers have bee 606 $aComputer networks$xQuality control 606 $aTelecommunication$xQuality control 606 $aTCP/IP (Computer network protocol) 615 0$aComputer networks$xQuality control. 615 0$aTelecommunication$xQuality control. 615 0$aTCP/IP (Computer network protocol) 676 $a004.6/6 676 $a621.3821 700 $aRa?isa?nen$b Vilho$0855344 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910143229803321 996 $aImplementing service quality in IP networks$91909552 997 $aUNINA
