Abstract

We describe a new control protocol called Adaptive Gateway Location Protocol (AGLP). In this protocol, a client requests a computation on a multimedia stream. AGLP discovers programmable Internet servers that process multimedia streams, and assigns the computation to one of these so-called gateways. AGLP continuously searches for alternate gateways, and, transparent to users, migrates computations between them to improve efficiency. The AGLP protocol uses soft-states for robustness and scale. Simulation results support that our protocol quickly locates gateways and migrates computations while keeping the load on the network low. We also outline planned enhancements to AGLP.
