Incentive Based Inter-domain Routing

The Internet’s inter-domain routeing system has evolved to keep pace with the Internet’s rapid growth, from a few co-operatively managed administrative domains to a large number of competetive domains. This growth has brought to light one of the Internet’s shortcomings: lack of support for efficient control and management of traffic, particularly between domains. This paper presents an extension to BGP, the inter-domain routeing protocol, that enables congestion to drive route selection and thus allows economic incentives to play their part in traffic distribution. Implementation in a deployed BGP stack is discussed and a simple simulation presented, showing better traffic distribution.
