Abstract
BGP-v4?s [RFC4271]path selection rule has been enforce since the
1990s. The Inter-Domain Working Group [IDR] will be considering
additions to the path selection [add-path][add-path-guidelines][path-
select-criteria] in 2011-2012.
This document provides a bibliography of publications (research and
public) regarding the bgp path selection.

Internet-Draft BGP Path Selection Bibliography 2011-10-23
1. Introduction
The IDR working group [IDR-WG] has several suggestion alternations to
the BGP route selection process [add-paths][add-path-guidlines][best-
path-select][aigp]
BGP-4?s current path selection has been encoded in routers for 20+
years and incorporates bgp update reception, bgp policy, and
convergence characteristics.
Any BGP-4?s current path selection requires careful consideration of
all the accumulated wisdom from academic research, industry research,
deployment investigations, and algorithm examinations. This document
seeks to provide a bibliography of this work that examines BGP basic
functions, performance, and suggested solutions.
Version-00 of this document is only a beginning of collecting these
resources.
2. Terminology
Atomized Routing ? modifying routing based on aggregate prefixes
into equivalence classes (policy atoms) based on common AS
path? from a topological perspectives [CAIDA-AR](section
3.8)
BGP-v4 [RFC 4721] ? Border Gateway Protocol version 4.
BGP Error reporting ? Errors reported within the BGP protocol.
BGP Flap Damping ? Damping of BGP route oscillations
BGP Monitoring messages ? Monitoring messages passed in the BGP
protocol
BGP Flap Damping ? Damping of BGP route oscillations
L3VPN ?Layer 3 MPLS VPN [RF
L2VPN ? Layer 2 MPLS VPN
L2VPN BGP Auto-discovery ? BGP distribution of L2 VPN endpoints
BGP Route Refresh ? Route Refresh Exchange in BGP to refresh the BGP
routes received from Peer.
