Context Broker Interfaces 330 $aFast and Efficient Context-Aware Services gives a thorough explanation of the state-of-the-art in Context-Aware-Services (CAS). The authors describe all major terms and components of CAS, defining context and discussing the requirements of context-aware applications and their use in 3rd generation services. The text covers the service creation problem as well as the network technology alternatives to support these services and discusses active and programmable networks in detail. It gives an insight into the practical approach followed in the CONTEXT project, supplying concrete guidelines for 410 0$aWiley series in communications networking & distributed systems. 606 $aComputer interfaces 606 $aComputer network architectures 615 0$aComputer interfaces. 615 0$aComputer network architectures. 676 $a006.3 676 $a658.812 701 $aRaz$b Danny$01727070 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910841742103321 996 $aFast and efficient context-aware services$94133785 997 $aUNINA
