Dear all, We are pleased to announce a first implementation of Babel-S, a variant of Babel able to distribute source-specific routes. The code is available using git clone -b source-specific git://git.wifi.pps.univ-paris-diderot.fr/babels.git with a web inteface on http://git.wifi.pps.univ-paris-diderot.fr/?p=babels.git and a backup on https://github.com/boutier/babeld Motivation ========== Consider the case of a multihomed network (a network connected to two ISPs). If the network is using provider-specific addresses, a packet needs to be routed to the right ISP depending on its *source* address. This is in contrast to traditional routing, which only considers the *destination* when making a routing decision. ISP A ISP B \ / packets \ / packets sourced \ / sourced from A \ / from B end node Markus Stenberg has recently published a prototype of source-specific routing for OSPF[1]. Babel-S is our attempt at a production-quality implementation of source-specific routing within the Babel routing protocol[2]. -- Michael Richardson <[email protected]>, Sandelman Software Works
