Abstract

Applications such as multimedia streaming for mobile users, or video conferencing, require support within the network for transcoding, compression etc. Proxylets running on servers within the network may be used to transform the media flows in order to meet application or QoS requirements. In this paper we examine the feasibility of performing constraint based configuration of the required proxylets. A set of constraints can be defined to select the required proxylets. A second stage is to define constraints relating to the placement of proxylets on nodes in the network. Eventually we will investigate the use of constraints for dynamic re-configuration to accommodate user mobility, or QoS variation. Some preliminary implementations of the architecture are presented and we discuss our approach to incorporate dynamic configuration to cater for load and QoS variations.
