Observations on Equation-Based Estimation of TCP-Compatible Rate for Multi-rate Multicast Scenariosd congestion control in principle. The benefit of such an approach is two-fold: on the one hand, participating receivers might base their join and leave decisions on the calculated rate, instead of probing for the appropriate subscription level; on the other hand, the sender side might adapt and opt

Smoothing the TCP Rate by Learning the Delay versus Window Size Dependencyetwork conditions are known to be unfavourable. TCP-L learns the relationship between its current (average) one-trip delay and its current window size when congestion occurs, leading to packet loss. After the learning phase, TCP-L will only probe for bandwidth by increasing its window if, under the

Most often analytical treatment falls short in being able to assess the overall system behaviour or performance. However, also simulation and testbed experiments alone often leave uneasiness with the results they deliver. The combination of simulation and testbed exper

Scheduling and Quality Differentiation in Differentiated Serviceservices. We focus on the differentiation of two important quality parameters, capacity and delay, and consider two models in detail: absolute capacity differentiation and proportional delay differentiation with delay bound. We suggest possible packet schedulers for implementing these models: DRR and

Performance Evaluation of the Preemptive Bandwidth Allocation Protocole limited resources of the network by preempting bandwidth of less prioritized streams. We assume that a connection will have different streams with predefined quality requirements and each stream will have a priority level assigned to it. When a new connection request comes to the network and there
