Disclosed are a cross-domain protection interacting method and system. The method comprises: an interconnecting node on a cross-domain working path between a first domain and a second domain sending second identification information of the second domain to a first node in the first domain, the first domain and the second domain being neighboring domains; when a link failure occurs in the first domain, an interconnecting backup node between the first domain and the second domain receiving first failure state information sent by the first node, the first failure state information carrying the second identification information; and the interconnecting backup node activating a second protection path in the second domain according to the second identification information, and using a first protection path in the first domain and the second protection path to implement cross-domain service transmission. The present invention can ensure protection independence in each domain and achieve an effect of interaction of cross-domain protection. |
