Global Routing Operations (grow) -------------------------------- Charter Last Modified: 2003-04-03 Current Status: Active Working Group Chair(s): David Meyer Vijay Gill Operations and Management Area Director(s): Randy Bush Bert Wijnen Operations and Management Area Advisor: Randy Bush Mailing Lists: General Discussion:grow@lists.uoregon.edu To Subscribe: majordomo@lists.uoregon.edu Archive: http://darkwing.uoregon.edu/~llynch/grow/ Description of Working Group: The Border Gateway Protocol (BGP) is fundamental to the operation of the Internet. In recent years, occurrences of BGP related operational issues have increased, and while overall understanding of the default-free routing system has improved, there is still a long and growing list of concerns. Among these are routing table growth rates, interaction of interior and exterior routing protocols, dynamic properties of the routing system, and the effects of routing policy on both the size and dynamic nature of the routing table. In addition, new and innovative uses of BGP, such as the use of BGP as a signaling protocol for some types of Virtual Private Networks, have created new and unexpected operational issues. The purpose of the GROW is continue and expand on the original charter of the PTOMAINE WG. In particular, the purpose of the GROW is to consider and measure the problem of routing table growth, the effects of the interactions between interior and exterior routing protocols, and the effect of address allocation policies and practices on the global routing system. Finally, where appropriate, the GROW documents the operational aspects of measurement, policy, security, and VPN infrastructures. GROW will also advise various working groups, including the IDR and RPSEC working groups, with respect whether it is addressing the relevant operational needs, and where appropriate, suggest course corrections. Finally, operational requirements developed in the GROW can also be used by any new working group charged with standardizing a next generation inter-domain routing protocol. GOALS: ----- (i). To provide a clear definition of the problems facing Internet Routing Scaling today. This includes routing table size and route processing load (former PTOMAINE goal). (ii). To collate measurements of routing table scaling data and publish a reference list (former PTOMAINE goal). (iii). To discuss and document methods of filtering/aggregating prefix information and to discuss and document what support from protocols or vendor knobs that might be helpful in doing this. In addition, to suggest policy guidelines to RIRs, LIRs and/or ISPs for allocations and aggregations,etc. that may be useful (former PTOMAINE goal). (iv). To determine the long and short term effects of filtering/aggregating prefixes to reduce router resource consumption. (v). To develop methods of controlling policy information propagation in order to limit the need for propagation of prefix sub-aggregates. (vi). To determine the effects of using BGP as a signaling mechanism on the scalability of BGP (e.g.,. draft-ietf-ppvpn-rfc2547bis-03.txt) (vii). To determine the effects of interaction of new IGP techniques (e.g., ISIS-TE) on the stability of BGP and in particular, what techniques are required to isolate the global infrastructure from the any of the dynamic properties of such TE systems. (viii). GROW will document operational aspects of routing security and will provide recommendations for protocol specific work to RPSEC, IDR, and other WGs in Routing area.
