Modeling and control of web servers

Participants : N. Marchand [contact person] , L. Malrait, S. Bouchenak [SARDES] .

This work focuses on the design of a server model, the design of admission control laws that allow the server to satisfy different Service Level Objectives, and the implementation of the latter. This work is in collaboration with Sardes team at INRIA, and is the topic of the Ph.D. thesis of Luc Malrait.

The first part of the work consisted in designing a continuous time model using a fluid flow approach. This model is then used for control purposes. We implemented this contribution on a real system which emulates an e-business environment [17] .

We are currently working on how this approach can be extended to multiserver systems, in the context of a new starting ANR project MyCloud.
