Embodiment Construction

[0019] In order to solve the problem that the DCN message forwarding between P-OTN equipment and OTN equipment cannot be realized in the prior art, the present invention provides a DCN message forwarding method based on P-OTN equipment. The following describes the present invention in conjunction with the accompanying drawings and embodiments For further details. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] There are PTN ports and OTN ports on the P-OTN equipment. As mentioned above, on the PTN port side, the P-OTN equipment naturally supports DCN intercommunication with other PTN equipment. For the situation on the OTN port side, the following The above method can realize DCN packet forwarding between the P-OTN equipment and other OTN equipment.

[0021] First of all, in terms of hardware environment, the PTN port is a port with the frame format defined by IEE...

Abstract

The invention discloses a data communication network message forwarding method base on a packet optical transport network device and an apparatus. Entire network routes at a PTN port side and an OTN port side in a P-OTN device are integrated to establish a DCN routing list. A three-layer conversion device receives DCN messages packaged in an Ethernet format of the P-OTN device, and the changing packaging is carried out on the DCN messages formats according to the types of a designation port, so that differences of concrete packaging formats between the PTN port and the OTN port are shielded, and DCN message forwarding between the PTN port and the OTN port in the P-OTN device is realized. Corresponding forwarding procedures are carried out at different ports, so that DCN intercommunication between the P-OTN device and an OTN device is realized. The data communication network message forwarding method base on the packet optical transport network device and the apparatus are used for solving problems of IP message intercommunication between the P-OTN port and an OTN port in the P-OTN device are solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for forwarding data communication network messages based on packet optical transport network equipment. Background technique [0002] Packet Transport Network (PTN) is an optical transport network architecture with packet services as the core and support for multi-service provision. Optical Transport Network (OTN) is a transport network that organizes networks at the optical layer based on wavelength division multiplexing technology. Packet Optical Transport Node (P-OTN) refers to an optical transport platform that integrates technologies such as PTN and OTN. Data Communication Network (DCN) is a network that supports layer 1 (physical layer), layer 2 (data link layer) and layer 3 (network layer) functions, and provides routing and switching functions, which can support The management communication of the management plane of PTN, P-OTN, OTN and other equip...
