From the Traffic Properties to Traffic Engineering Inthe Internet: Implications of the Traffic Properties Ontraffic Engineering with Bgp: the View from Stub Ases.

Due to concerns about resilience and performance,more and more stub networks in the Internet rely on multi-homing. Multi-homing consists in connectinga network to the Internet at different access points. As traffic leaves and enters the networkthrough several access links, multi-homed networks need to control their traffic, also called trafficengineering. Multi-homed networks typically perform traffic engineering by tweaking the BGP routingprotocol. The purpose of BGP is to distribute the information about reachable networks across the wholeInternet, not to perform traffic engineering. It is thus important for multi-homed networks to knowthe complexity of traffic engineering with BGP. In this book, we explain how BGP can be used toengineer the traffic and what can be expected from doing it. The content of this book targets two typesof readers. First, the network managers of small to medium-size stub networks will better understandBGP and how to use it to engineer their traffic. Second, researchers in networking will learn aboutthree different research areas: Internet traffic characteristics, interdomain routing, andevolutionary optimization.
