Method and device for establishing multi-domain multi-layer connectivity service

An apparatus for establishing multi-domain multi-layer connectivity service, comprising:

• a processor and a storage medium storing programs, wherein the programs, when executed by the processor, comprises:
• a first receiving module, which is configured to receive a multi-domain multi-layer connectivity service establishment request, wherein the multi-domain multi-layer connectivity service establishment request is used for requesting establishment of multi-domain multi-layer connectivity service between a first service interface point of a first control domain and a second service interface point of a second control domain, and the multi-domain multi-layer connectivity service establishment request carries an identifier of the first service interface point, first configuration information of two or more network layer protocols of the first service interface point, an identifier of the second service interface point, and second configuration information of two or more network layer protocols of the second service interface point;
• and
• a first establishment module, which is configured to establish the multi-domain multi-layer connectivity service according to the multi-domain multi-layer connectivity service establishment request.
