Improvements in the Path Vector Approach for Inter-Domain Routing
Jawwad Haider, Muhmmad A.U. Khan and Sohail Razzaq

Abstract: The Border Gateway Protocol (BGP) is an inter-autonomous system routing protocol designed for TCP/IP Internets. Currently in the Internet Border Gateway Protocol (IBGP) deployments are configured such that all Border Gateway Protocol (BGP) speakers within a single Autonomous System (AS) must be fully associated so that any external routing information must be re-distributed to all other routers within that Autonomous System (AS). This represents a serious scaling problem. It over loads the memory and processor utilization of Internet backbone routers, increases the traffic load on internet backbone links there by increasing the over all convergence time of the Internet. This document describes the use and design of a method known as Path Relay (PR) technique to alleviate the need for full association (IBGP). This technique results in increasing the network performance in terms of backbone router processor and memory utilization backbone link bandwidth utilization and over all convergence time of the network. This performance up gradation is clearly evident from the results of the pilot deployment of PR.
