(scalability!!) each point where CAC is performed should be loaded up to AC limit -> supplementary traffic generators cooperating with a resource reservation system are needed. Network Anomaly Detection should be oriented on traffic carried inside CoSs  Connection Admission Control Measurements Based AC (MBAC) is aimed to make CAC less preventive there are some methods for streaming traffic, e.g. Hoeffding bounds, methods for elastic traffic are also needed problems with methods/tools for measuring traffic load on high speed links and in short time scale call setup proceeding requires information about availability of QoS paths (routing). tools for routing acquisition are needed (especially inter-domain).  Traffic Engineering and Resource Optimisation (TERO) traffic matrix estimation for each CoS monitoring of overprovisioning ?
