By extending the system theory under the (min,+)-algebra to the time varying setting, we solve the problem of constrained traffic regulation and develop a calculus for dynamic service guarantees. For a constrained traffic regulation problem with maximum to ...
Connection Admission Control (CAC) algorithms are used to decide whether an incoming connection should be accepted or rejected in a node of a network offering reservation based services in order to maintain the guaranteed Quality of Service (QoS) in the ne ...
The best-effort service offered by the Internet is not suitable for a large variety of multimedia applications, which require strict guarantees on losses and end-to-end delay. We design functionalities and mechanisms for RTP in order to provide a transport ...
The ever-growing popularity of the Internet is dramatically changing the landscape of the communications market place. The two separate worlds of the Internet and Telecommunications are converging. The respective advantages of the two environments are bein ...
Alternative Best-Effort (ABE) is a novel service for IP networks which offers applications the choice between receiving a lower end-to-end delay and receiving more overall throughput. Every best effort packet is marked as either green or blue. Green packet ...

We compare the performance of ABR and UBR for providing high-speed network interconnection services for TCP traffic. We test the hypothesis that UBR with adequate buffering in the ATM switches results in better overall goodput for TCP traffic than explicit ...
The performance limits of the current Internet make the integration of IP with ATM a hotly debated issue in the networking arena, leading to various competing approaches and products. Legitimate technical and market issues are, however, often intertwined w ...
Recent Linux kernels offer a wide variety of traffic control functions, which can be combined in a modular way. We have designed support for Differentiated Services based on the existing traffic control elements, and we have implemented new components wher ...
Recent developments in transmission and switching technology has made available low-cost gigabit network capacity forpacket-based WANs (e.g., IP over WDM), that will not require the intermediate SONET/SDH multiplexing layer. For competitive operators that ...
