MULTI-DOMAIN CONTROLLER, SINGLE-DOMAIN CONTROLLER, AND SOFTWARE-DEFINED OPTICAL NETWORK SYSTEM AND METHOD

摘要

Disclosed are a multi-domain controller, a single-domain controller, and a software-defined optical network system and method. The multi-domain controller at least comprises a virtual network service manager. The virtual network service manager is configured to process a cross-domain or single-domain virtual optical network service (VONS) service request from an application layer. The cross-domain VONS service request is divided into two parts to be processed: an inter-domain part and each intra-single-domain part. The inter-domain part of the cross-domain VONS service request is processed by the multi-domain controller, wherein with regard to a service request for a bandwidth on demand (BOD) connection attribute in the cross-domain VONS service request, the request is forwarded to a routing connection controller, and with regard to a service request for an optical virtual private network (OVPN) attribute in the cross-domain VONS service request, OVPN service processing comprising establishment and deletion is performed according to acquired virtual network layer resources.
