Abstract (en)
[origin: WO2006128894A1] The invention relates to a method for providing substitute routes in rapid response to the failure of a link between two routing domains (AS-6, AS-8) in a packet-oriented network. According to the invention, an inter-domain router (R1) determines substitute routes for fault scenarios caused by link failures. The substitute routes are stored and are regularly checked for their availability. This makes it possible to ensure, to a high degree, that a substitute route which is suitable for diverting the traffic is ready in the event of a link failing.
