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

摘要

A multi-domain controller, a single-domain controller, a software defined optical network system and a method are disclosed. The multi-domain controller at least comprises a virtual network service manager arranged to: process a cross-domain or single-domain Virtual Optical Network Service (VONS) request sent from an application layer and divide the cross-domain VONS request into an inter-domain part to be processed and an intra-domain part to be processed, the intra-domain part including multiple intra-single-domain parts; the inter-domain part of the VONS request is processed by a multi-domain controller, wherein the service request for a Bandwidth On Demand (BOD) connection attribute which is included in the cross-domain VONS request is forwarded by a routing connection controller, and an Optical Virtual Private Network (OVPN) service processing, which includes establishment and deletion, is performed on the service request for an OVPN attribute which is included in the cross-domain VONS request according to the virtual network layer resources acquired.
