Abstract: A method of sharing network resource and associated network coordination apparatus are provided. The method includes following steps. Firstly, a resource sharing request from a tenant is received. Then, a controller is requested to determine whether resource of a shared transport network is satisfied with the resource sharing request. A tenant ID is generated for the tenant when the controller determines the resource of the shared transport network is satisfied with the resource sharing request. The tenant ID is transmitted to the tenant. The controller is requested to generate at least one packet header for at least one transport service type corresponding to the each of at least one group ID, and further update a plurality of flow tables of the plurality of forward devices according to the at least one packet header.

Abstract: Accordingly, the disclosure provides a handover optimization method used by a network controller of a transport network and a network controller using the same method.
