Differentiated services enhancements for efficient IP QoS implementation
To enhance the deployment of DifServ network we propose two mechanisms, i.e. Connection Admission Control (CAC) facility and hierarchical scheduling. In this paper we describe both facilities and report the results of the simulation work. Simulation work was conducted using ns-2. The CAC scheme is p...
