Implications of Interdomain Traffic Characteristics on Traffic Engineering

Implications of Interdomain Traffic Characteristics on Traffic Engineering

We study the interdomain traffic as seen by a non-transit ISP, based on a six days trace covering all the interdomain links of this ISP. Our analysis considers the relationships between the interdomain traffic and the interdomain topology. We first discuss the day-to-day stability of the interdomain traffic matrix to evaluate the feasibility of interdomain traffic engineering. Then, we study th...

Implications of Traffic Characteristics on Interdomain Traffic Engineering

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...
