The present invention provides a service deployment method and apparatus, and a network device. The method includes: receiving a service path computation request sent by a node; determining a first idle resource in all resources of a network except a critical resource, where the critical resource is a resource that enables an existing service path in the network to meet a survivability requirement; performing service path computation based on the first idle resource, to obtain a first service path; performing, based on the first idle resource, simulation survivability analysis on the first service path; and if the first service path meets the survivability requirement, sending the first service path to the node. In embodiments of the present invention, based on an idle resource except a critical resource that enables an existing service in a network to meet a survivability requirement, service path computation and simulation survivability analysis are performed on a new service. Therefore, a time for service deployment is reduced, and efficiency of establishing a new service path is improved. |
