Our paper submitted to the 21st International Teletraffic Congress (ITC 21) has been accepted for publication. Abstract:

The migration of voice communication from the Public Switched Telephone Network to the Internet pushes the need to adequately size network resources such as buffers and capacity. This paper addresses the problem of how these resources should be scaled in the number of voice flows N in order to guarantee predefined packet loss probabilities and end-to-end delays. By deriving non-asymptotic buffer overflow probabilities at both edge and interior network nodes, the paper demonstrates that O(1) buffers are sufficient to ensure probabilistic packet loss constraints at all utilizations. Also, by deriving end-to-end delay bounds, the paper shows that the required per-flow capacities decrease as O(1/N) when probabilistic end-to-end delay guarantees are sought. Numerical examples illustrate that statistical multiplexing dominates the effect of scheduling in multi-nodes scenarios with high capacities.

My journal paper entitled Stochastic Packet Loss Model to Evaluate QoE Impairments that appeared in issue 1 / 2009 of the PIK journal is now online.

At the KiVS 2009 conference, I received the Master Thesis Award from the communication in distributed systems (KuVS) group for my thesis entitled Statistical Error Model to Impair an H.264 Decoder. See a copy of the award here and retrieve the slides of my talk here. Please find below some pictures of the award session, taken by KiVS organisers.

Professor Lars Wolf, head of the award comitee, ceremoniously presented the KuVS award to me.

I’m leaving for KiVS’09 (conference on communication in distributed systems), where I will give a talk entitled “Stochastic Packet Loss Model to Evaluate QoE Impairments” in the award session (I will receive the master thesis award from the communication in distributed systems group). Although there is a paper deadline approaching, I hope to have a little blog coverage on the conference.

Hi everyone,

I’m glad to announce that I don’t belong to 82 % of authors whose paper has been rejected from the IEEE IWQoS 2008 (acceptance rate 18 % for full papers in 2006). So I’m currently preparing the camera ready version of my paper and looking forward to a trip to The Netherlands in order to present it in June. I’ll post more information regarding the paper as soon as I’m done with the camera ready version.
