Route Bazaar: Automatic Interdomain Contract Negotiation

8 Apr

Ignacio Castro, IMDEA Networks Institute and Internet Interdisciplinary Institute (IN3), Open University of Catalonia, Barcelona, Spain

In-house Presentation

While some see in Border Gateway Protocol (BGP) a routing ambrosia to be enshrined, others perceive a basis of serious Internet connectivity limitations. Because the interdomain routing protocol realizes contracts between Autonomous Systems (ASes), this paper argues that contractual and routing issues need to be tackled jointly to overcome the connectivity limitations. We propose Route Bazaar, a backward-compatible system for flexible Internet connectivity. Inspired by the decentralized construction of trust in cryptocurrencies, Route Bazaar uses a decentralized public ledger and cryptography to provide ASes with automatic means to form, establish, and verify end-to-end connectivity agreements.
