| description | A method and device for long-term storage of cross-domain path information are provided. The method is applied on a stateless PCE. In the method, a first PCE computes a path; a path head node sends, to the first PCE, query information for querying intra-domain path information of the first domain corresponding to a first PATH-KEY, generates, on the basis of a query result returned by the first PCE, a third PATH-KEY having a unique identifier and corresponding to the intra-domain path information of the first domain and stores the third PATH-KEY; the path head node sends, to a head node in a second domain, an inter-domain path establishment signalling comprising the third PATH-KEY and a second PATH-KEY, to make the head node in the second domain send, to a second PCE, query information for querying intra-domain path information of the second domain corresponding to the second PATH-KEY, generate, on the basis of a query result returned by the second PCE, a fourth PATH-KEY having a unique identifier and corresponding to the intra-domain path information of the second domain, and store the fourth PATH-KEY; and, the path head node modifies information of the path from the path head node to the path tail node on the basis of a reverse signalling returned by the path tail node and comprising the third PATH-KEY and the fourth PATH-KEY |
