AbstractMultimedia and P2P le sharing applications (YouTube, online gaming, BitTorrent and live streaming of sporting events) are responsible for generating majority of the trac in the Internet. The ever increasing volume of trac o ers new challenges to trac optimizations in the network. Extracting the topolgical information from the ISPs via cross layer cooperation to direct trac is a promising solution. IETF is specifying a protocol called Application Layer Trac Optimization (ALTO) protocol that provides guidance to the overlay applications to route trac based on abstract network information from the unerlying network provider, typically ISPs. This research study focuses on implementation of a prototype called Multi-Cost ALTO extended DNS. Multi-Cost ALTO is a proposed extension of baseline ALTO which supports multiple cost types and cost modes in a single transaction of endpoint cost query. It is integrated with a DNS server for the prototype. The major part of the research is focused on design, implementation and analysis of the ALTO Quality Man- ager (AQM), which is the decision module of the prototype. To motivate the adoption of Multi-Cost ALTO, numerical results are provided in terms of the amount of trac volume saved from adopting Multi-Cost ALTO over baseline ALTO. The research study also focuses on bene ts of ALTO integration in Content Delivery Networks (CDN) and Peer to Peer (P2P) applications.
