Patent ID: 10411911

Abstract:
A network as a service (NaaS) service cross-domain orchestration method to implement an end-to-end NaaS service in a multi-domain network that includes multiple network domains where the method includes obtaining information about a first user-to-network interface (UNI) and information about a second UNI in a multi-domain network according to a received NaaS service request, where the NaaS service request is used to request to establish an NaaS service between a first terminal and a second terminal; querying domain resource information to obtain a cross-domain path between the first UNI and the second UNI; determining network domains that the cross-domain path passes through, and obtaining a first connection requirement and a second connection requirement of each network domain of the network domains that the cross-domain path passes through; and sending the first connection requirement and the second connection requirement to a control device in each network domain.
