An Evaluation of BGP-based Traffic Engineering Techniques
نویسنده
چکیده
We analyze several types of interdomain traffic engineering techniques. First, we briefly describe interdomain routing and the BGP protocol. Then, we summarize the characteristics of interdomain traffic based on measurements with two different ISPs. We evaluate how a typical ISP can select its upstream providers and show that with the BGP decision process many routes are selected non-deterministically. We then evaluate with simulations the performance of BGP-based traffic engineering techniques that are currently used on the Internet and show their limitations.

Techniques for Interdomain Traffic Engineering
Network operators must have control over the flow of traffic into, out of, and across their networks. However, the Border Gateway Protocol (BGP) does not facilitate common traffic engineering tasks, such as balancing load across multiple links to a neighboring AS or directing traffic to a different neighbor. Solving these problems is difficult because the number of possible changes to routing p...
متن کاملTweak-it: BGP-based Interdomain Traffic Engineering for transit ASes
Today, engineering interdomain traffic in large transit ASes is a difficult task due the opacity of BGP and the complex interactions between the BGP decision process and IGP routing. In this paper we propose Tweak-it, a tool that, based on the steady-state view of BGP routing inside the AS and the traffic demands of the AS, computes the BGP updates to be sent to the ingress routers of a transit...
متن کاملOn the use of BGP communities for fine-grained inbound traffic engineering
In the context of Border Gateway Protocol (BGP), inbound inter-domain traffic engineering (TE) remains a difficult problem without panacea. Each of previously investigated method solves a part of the problem. In this study, we try to complement the map by exploring the use of BGP communities. With BGP community based polices enabled in transit provider networks, we are able to manipulate incomi...
متن کاملAchieving Fast BGP Reroute with Traffic Engineering Using Multiple Routing Planes
In today's BGP routing architecture, traffic delivery is in general based on single path selection paradigms. The lack of path diversity hinders the support for resilience, traffic engineering and QoS provisioning across the Internet. Some recently proposed multi-plane extensions to BGP offer a promising mechanism to enable diverse inter-domain routes towards destination prefixes. Based on thes...
متن کاملA performance evaluation of BGP-based traffic engineering
Many Internet Service Providers tune the configuration of the Border Gateway Protocol on their routers to control their traffic. Content providers often need to control their outgoing traffic while access providers need to control their incoming traffic. We show, by means of measurements and simulations, that controlling the flow of the incoming interdomain traffic is a difficult problem. For t...
