Abstract

The invention discloses a DCN processing system of a packet and optical transport network fusion product. The DCN processing system comprises a packet control plane, a packet forwarding plane and an optical transport network forwarding plane. The invention further discloses a processing method of the file processing system. According to the invention, the corresponding virtual port of the OTN network is generated on the grouping equipment, and the PTN and the OTN are connected together according to different network forwarding characteristics through the corresponding relationship between thecontrol forwarding of the grouping and the OTN network, so that the purpose of transmitting the control information is achieved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a DCN processing method and system for a product integrating packet and optical transport network. Background technique [0002] A packet transport network (Packet Transport Network, PTN) is a transport network oriented to packet data services with packet switching as the core. PTN is also a packet forwarding, connection-oriented multi-service transmission technology. [0003] The optical transport network (OTN) technology is the product of the compromise between the electrical network and the all-optical network. It transplants the powerful and perfect OAM&P concept and functions of SDH into the WDM optical network, effectively making up for the shortcomings of the existing WDM system in performance monitoring and maintenance management. insufficient. [0004] As mobile services enter the 4G and 5G era, a large amount of information data needs to be sent from one...
