Developing the Fringe Routing Protocol

Abstract: 

The purpose of an ISP's network is to connect internal clients with a high speed external link. Most traffic on the network moves between an internal client and the external world via the backbone. But what about traffic between two clients of the ISP? Ideally, from the ISP point of view, this traffic will go up to the backbone and down again but it is possible that it may find another route along a redundant backup path. The Fringe Routing Protocol sits on the client fringes of this ISP style of network. It manipulates the route cost calculation so that paths towards backbone gateways become more attractive than paths away from the gateway, sending traffic in the preferred direction unless the 'shortcut' is very attractive or the backbone link has disappeared.

This presentation follows the development of the Fringe Routing Protocol from initial concept through to the realities and problems of creating a FRP daemon for the Quagga open source software routing suite.
