ABSTRACT:
A method for communicating risk information within a network including a plurality of domains connected to one another at the border nodes of said domains, characterized by steps consisting of:determining a connection path within a first domain (2), said path running between a border node (N21) of the first domain connected to a second domain and a recipient node,determining a set of shared risk groups of the first domain which the connection path crosses,assigning a shared risk identification code to said connection path,storing, within a shared risk group management device (28) associated with the first domain, a data structure associating said shared risk identification code with said set of shared risk groups.
