Abstract
Node devices of a mesh communications network are interconnected by links. Forwarding tables are initially built following a link-state routing protocol. Each node device performs, upon detecting a link failure or a link recovery, determining and transmitting. Each end-point, when receiving said message(s) representative of said link failure or said link recovery, records an indication of whether each data path identified in the received message(s) can be activated or not. When the received message(s) is(are) representative of a link failure, each end-point performs selecting and transmitting.
