Éléments de gestion des ressources de calcul dans les réseaux actifs hétérogènes

Abstract : Active network technology envisions deployment of virtual execution environments within network elements, such as switches and routers, so that inhomogeneous processing can be applied to network traffic associated with services, flows, or even individual packets. To use such a technology safely and efficiently, individual nodes must have a meaningful understanding of the resource requirements for specifie network traffic. Well-accepted metrics exist for expressing bandwidth requirements (bits per second) and memory requirements (bytes) in units independent of the capabilities of particular nodes. Unfortunately, no well-accepted metric exists for meaningfully expressing processing (i.e., CPU time) requirements in a platform-independent form. Based on its execution trace, we model an active application as a set of scenario Each scenario has a probability of occurrence and is characterized by the set of node services called by the packets of the application during their execution. Node performances are captured by specific benchmarks. The combination of these information allows anode to predict how many CPU time an active application will need to execute. We show that the node can then use this prediction to manage more efficiently its resources. We also propose model evolutions to validate the approach in more general contexts.
