This paper addresses efficient packet loss recovery by retransmission in window-based congestion control protocols. It builds on explicit congestion control mechanisms to decouple the packet loss detection from the congestion feedback signals. Implicit alg ...
We consider a FIFO multiplexer fed by flows that are individually constrained by arrival curves, and look for the best possible arrival curve for every output flow. This problem arises in scenarios where aggregate multiplexing is performed, such as differe ...
A stage-by-stage analysis of light propagation around a 90° corner in a two-dimensional photonic crystal waveguide was discussed. The coupling efficiency between the conventional ridge waveguide and the photonic crystal waveguide was quantified using a ser ...
We present practical and theoretical, stage-by-stage analysis of light propagation around a 90degrees corner in a two-dimensional photonic crystal waveguide. Using a series of different samples we quantify the coupling efficiency between the conventional r ...
We consider the transmission of variable bit rate video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming with a tr ...

The min-plus theory of greedy shapers has been developed after Cruz`s results on the calculus of network delays. An example of greedy shaper is the buffered leaky bucket controller. The theory of greedy shapers establishes a number of properties such as th ...
Numerous approaches have been proposed to manage Quality of Service in the Internet. However, none of them was successfully deployed in a commercial IP backbone, mostly because of their complexity. In this paper, we take advantage of the excess network ban ...
We consider the definition of the Expedited Forwarding Per-Hop Behaviour (EF PHB) as given in RFC 2598\ \cite{rfc2598}, and its impact on worst case end-to-end delay jitter. On one hand, the definition in RFC 2598 can be used to predict extremely low end-t ...
