Proposed IPV6 Aggregation Scheme

Abstract

Ever since the inception of Internet, scalability has been a major concern to the Internet world. As many Internet Protocol addresses are allocated/assigned, there is rapid increase in the routing table. In view of ameliorating this pitfall, there is need for proper aggregation. Aggregation is the key solution to solving the increase of allocated addresses in the routing table, but the major problem is how aggregation can take into account multihoming, and traffic engineering while maintaining maximal reduction in routing table. Much has being said about the advantages of aggregation and how to reduce the Border Gateway Protocol (BGP) routing table, the impact of multihoming, traffic engineering, etc., but no extensive work has being done on the impacts of aggregation on routes as viewed by the up- and down-stream ISPs. In this research, we evaluate and quantify different routing table entries in three major aggregation strategies which includes - prefix, path and origin aggregations. In the analysis, we were able to justify these aggregations and proposed the best aggregation strategy for new IPv6.
