Analyzing possible caching gain in IP access networks

Background: Celtic IPNQSIS (http://ipnqsis.org) is a European research project with the aim of developing monitoring systems for studying the behaviour of Quality of Experience (QoE) through analysis of network and service performance and their impact on end customers. A part of the project is to analyze traffic in live IP access networks, in order to gain knowledge of traffic patterns and user behavior. Parameters of interest are e.g. applications used, traffic load, usage patterns etc. In this particular master project, the purpose is to investigate traffic traces with the aim of analyzing caching gain. Caching of content in the access network, closer to the end users is a possible strategy for offloading core network links and providing better performance for end users.
Tasks for the project worker:
• Analyze state of the art in caching
• Analyze existing caching strategies
• Analyze traffic traces, to compute possible bandwidth gain by providing local access to content
• Simulate the possible bandwidth gain by implementing various caching strategies
Requirements: Linux, linux admin, databases sql, networks - ethernet/IP, programming (e.g. C, C++, python)
