THE AMAZING DUAL ROLE PLAYER - BIGP

Abstract

The protocols EGP and IGP are the two key components of the present internet infrastructure. In a domain, routers forward IP packet within and between domains. Each domain uses an intra-domain routing protocol known as Interior Gateway Protocol (IGP) like IS-IS, OSPF, RIP etc to populate the routing tables of its routers. Between domains routing information must also be exchanged to ensure that a host in one domain can reach another host in remote domain. The inter-domain routing protocol performing this is called Exterior Gateway Protocol (EGP). Basically EGP used nowadays is Border Gateway Protocol (BGP). The fundamental difference between the two is that BGP has smaller convergence as compared to the IGP’s. On the other hand IGP has lesser scalability as compared to BGP. So through this paper there is a proposal to create a new protocol which can act as an IGP (when we consider inter-domain transfer of traffic) and also can act as BGP (when we consider intra-domain transfer of traffic).
