Embodiment 1

[0078] Embodiment 1: An example of the component architecture of the SDON multi-domain controller in the SDON architecture system.

[0079] The SDON architecture system includes: an application layer, a controller layer, and a device layer, wherein the controller layer includes a multi-domain controller layer and a single-domain controller layer, such as Figure 4 Shown is an embodiment of the SDON architecture system. In this embodiment, the detailed description of the component functions of the component architecture of the SDON multi-domain controller is as follows:

[0080] 1. The virtual network service manager 101—belongs to the key component of the controller, and its main functions are as follows:

[0081] 1. Handle cross-domain or single-domain VONS service requests from application layer users. The cross-domain VONS service request is divided into two parts for processing: the inter-domain part and the part within each single domain. For the inter-domain part of th...

Embodiment 2

[0102] Embodiment 2: an example of the component architecture of the SDON single domain controller in the SDON architecture system.

[0103] The SDON architecture system includes: an application layer, a controller layer, and a device layer, wherein the controller layer includes a multi-domain controller layer and a single-domain controller layer, such as Figure 5 Shown is an embodiment of the SDON architecture system. In this embodiment, the detailed description of the component functions of the component architecture of the SDON single domain controller is as follows:

[0104] 1. The virtual network service manager 201—belongs to the key component of the controller, and its main functions are as follows:

[0105] 1. Process virtual network service requests from multi-domain controllers in this domain: service requests for connection attributes such as BOD will be forwarded to the routing connection controller; service requests for OVPN attributes will be based on the obtain...

Embodiment 3

[0126] Embodiment 3: an example of each message exchange protocol in the SDON architecture system.

[0127] 1. The content of the message exchanged between the application layer and the multi-domain controller is as follows:

[0128] a. Cross-domain virtual optical network service VONS request and response, the request includes the establishment, deletion, attribute modification, query and other operations of cross-domain BOD, OPVN and other services.

[0129] b. Single domain virtual optical network service VONS request and response.

[0130] c. Session and handshake messages of PCEP+ / OPENFLOW / Restful / SNMP protocol.

[0131] d. Reported by the multi-domain controller and provided according to the user level, limited and open cross-domain virtual optical network layer topology information.

[0132] e. Reported by the multi-domain controller, limited and open single-domain virtual optical network layer topology information provided according to the user level.

[0133] 2. Th...
