Abstract
A method of controlling routing in a packet network supported by a transport network allowing the dynamic creation/suppression of links for transporting packets of said packet network, said method including a routing step, a step of informing other routers of said network of the metric assigned to each link of the packet network, and a step of creating/destroying a link. The link may have three states: a non-connected state if said two routers cannot be directly connected, a virtual connection state wherein a virtual metric is assigned to said link between said head end router and said tail end router of the same communication, and a real connection state wherein a real metric is normally assigned to said link.
