Retroactive Packet Sampling for Traffic Receipts

Adrian Perrig, Christos Pappas, Pavlos Nikolopoulos

Is it possible to design a packet-sampling algorithm that prevents the network node that performs the sampling from treating the sampled packets preferentially? We study this problem in the context of designing a "network transparency" system. In this syst ...

Improved Utility-based Congestion Control for Low-Delay Communication

Pascal Frossard, Sergio Mena, Laura Toni, Stefano D'Aronco

Due to the presence of buffers in the inner network nodes, each congestion event leads to buffer queueing and thus to an increasing end-to-end delay. In the case of delay sensitive applications, a large delay might not be acceptable and a solution to prope ...
