With the information flow in the network growing rapidly and the size of network extending gradually, it is essential that SDON networking supports multi-domain optical services. Since the type of network has moved toward complicated and converged, the disparate network resource has interlaced, an isomerized network situation is the trend in the future. Accordingly, end-to-end (E2E) services have shifted from a single service provider domain towards a multi-domain service provider. On this condition, the traditional isolated networking mode is so difficult to meet the current demand. E2E multi-domain services are the trend in the future. This paper proposes a multi-domain service dispatching scheme based on SDON virtualized network. By sending concurrent http requests to controller multiple single-domain controllers, web service management will manage optical devices and achieve E2E multi-domain service requests over this scheme. The management layer establishes E2E services dispatching system in multi-domain virtual optical network and it changes the present situation of disparate single service provider incompatibility. The experiment also indicates the reality possibility of the multi-domain dispatching scheme. This scheme will provide basis for the large scale multi-domain networking based on SDON in the future.
