Abstract:
Media content streaming and delivery is nowadays a high popularity service in Internet. Complex architectures like Content Delivery Networks, Content Aware/Oriented Networks have been proposed, where information/content objects are treated as first-class abstractions. As alternative, light architectures, are investigated and implemented, working on top of the current IP networking technologies. In both types of architectures, appropriate content server and path selection constitute the primary set of actions to be performed in the content delivery systems. Such a problem belongs to the general class of multi-criteria optimization problem, having (in our case) as input, some information on servers, network and user context. This paper contains an extension of a preliminary work, focused on algorithms and policies for optimized paths and server selection. Simulation study results are presented here, to illustrate the better performance of multi-criteria optimization algorithms versus random path and/or server selection. Flexibility of the solution is emphasized, including the possibility to naturally add new criteria (business, policies) in the selection process. This work is a part of a larger effort, aiming to finally implement a subsystem in the framework of a content delivery light architecture system.
