However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in...It begins by examining the mechanisms that already existed in fixed IP data networks prior to the introduction of probe and agent technology. A look at these later developments is then supplemented with a real-world scenario of 606 $aComputer networks$xManagement 606 $aWireless communication systems$xManagement 606 $aCell phone systems$xManagement 606 $aCustomer services 615 0$aComputer networks$xManagement. 615 0$aWireless communication systems$xManagement. 615 0$aCell phone systems$xManagement. 615 0$aCustomer services. 676 $a384.5 676 $a621.3821 676 $a658.8/4 700 $aMassam$b Peter$01842011 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911019715103321 996 $aManaging service level quality across wireless and fixed networks$94421943 997 $aUNINA
