Proposal of a price-based inter-AS policy routing to improve Ases' profits

摘要

At present, the global Internet consists of many ASes. Each AS pays a pre-determined connection fed to another AS for connecting its network with that AS's network. The con- Nection fee type charging may be rational in case of transferring The best-effort type traffic. However, usage charging is necessary To transferring the resource guaranteed type traffic such as the Intserv traffic and the Diffserv traffic. In this case, each AS pays A per-flow fee to another AS every time it routes a flow into an- Other AS. The per-flow fee paid by each AS becomes a part of The cost that AS. Thus, each AS needs to select a route with The lowest price to improve its own profit.
