Cooperative Interdomain Traffic Engineering Using Nash Bargaining and Decomposition

Using Redistribution Communities for Interdomain Traffic Engineering

Various traffic engineering techniques have been proposed and are used to control the flow of IP packets inside large ISP networks. However, few techniques have been proposed to control the flow of packets between domains. In this paper, we focus on the needs of stub ISPs that compose 80% of the global Internet. We first describe the typical traffic pattern of such a stub ISP. Then we briefly d...

Towards Coordinated Interdomain Traffic Engineering

We argue that today’s ad hoc inter-domain traffic engineering techniques be replaced with an architecture that is based on explicit coordination between ISPs. With explicit coordination, ISPs exchange information about their traffic and routing options, and all ISPs impacted by a potential routing change negotiate the actual change. This increases efficiency because it allows ISPs to find “win-...

BGP-based Interdomain Traffic Engineering

Preamble In a few years, the Internet has rapidly evolved from a research network serving a handful of users to a huge interconnection of about 350 million hosts (June 2005 [ISC05]). In this way, the Internet is the largest distributed system ever built. The Internet is organized in a multitude of administratively independent networks called domains or Autonomous Systems (AS). For example, an A...

Interdomain traffic engineering with MPLS

Interdomain traffic engineering with BGP

Traffic engineering is performed by means of a set of techniques that can be used to better control the flow of packets inside an IP network. We discuss the utilization of these techniques across interdomain boundaries in the global Internet. We first analyze the characteristics of interdomain traffic on the basis of measurements from three different Internet service providers and show that a s...
