Robert Raszuk, Cisco Systems

Robert Raszuk graduated with Master’s degree from Warsaw University of Technology, Faculty of Electronics in 1995. During last years of his university he established “Internet Access” company which focused on providing services of interconnecting enterprises to Internet via local ISPs in Poland.<BR> <BR> Shortly after graduation he started to work for Network Engineering at Nations Bank where his duties and responsibilities included running national routing backbone as well as designing migration of most campuses to ethernet catalyst switches from token ring and FDDI technologies.<BR> <BR> Since 1997 he has been working for routing equipment vendors initially in Customer Support team then from 1999 in the Routing Protocol Development Engineering teams.<BR> <BR> He is author & co-author of over 40 patents, number of IETF drafts and RFCs. His focus has been during last years concentrated on large scale routing (mainly BGP), mpls and it’s applications. He has over 16 years of practical experience in the computer networking industry. His priority has always been to help internet service providers to build and effectively operate IP networks.<BR> <BR> Currently he is Principal Engineer in IOS Routing Protocols Development group in Cisco Systems Engineering.
Abstract: The goal of the talk is to discuss applicability of add-paths scheme. It brings the original ISP design and demonstrates how with the current
set of available BGP tools achieve the same level of fast connectivity restoration or load balancing as one may claim to be possible only with add-paths.



An alternative to add-paths - diverse BGP paths distribution is presented. The analogy to MPLS networks is made with demonstration of it's original flat design scalability challenges and proposed industry solution.



Conclusion shows possible network design with main goals of simplicity, ease of deployment, ability to meet fast connectivity restoration goals and true multi service nature to carry any kind of application over IP.
