NANOG Meeting Presentation Abstract

BGP Error Handling
Meeting:	NANOG51
Date / Time:	2011-02-01 11:30am - 12:00pm
Room:	Grand
Presenters:	Speakers: Rob Shakir, Cable&Wireless Worlwide Rob works within the Network Design team in Cable&Wireless Worldwide, with a direct involvement in the architecture and design of global MPLS/IP platforms. His previous roles have been in operational teams - with experience in both network and hosting service providers. Rob maintains a strong interest in improving network protocols to meet the demands of operator networks, and is a regular contributor to various forums on this subject, with a particular focus on BGP-4.
Abstract:	BGP-4 is utilised as a key intra- and inter-Autonomous System routing protocol in modern IP networks. The failure modes as defined by the original protocol standards are based on a number of assumptions around the impact of session failure. Numerous failures, both within the Internet, and Service Provider networks have resulted in reacting to errors in a single UPDATE message resulting in large-scale failures in one or more Autonomous Systems' IP network. This presentation intends to support a draft describing the current use of BGP-4 within Service Provider networks, and outlining a set of requirements for further work to enhance the mechanisms available to a BGP-4 implementation when erroneous data is detected. It is intended that the draft supported by this presentation is reflective of operator's requirements, based on their BGP deployments, and forms a basis for an approach to BGP error handling enhancements.
