Example Embodiment

[0064] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0065] image 3 It is an optical network node structure diagram that includes a centralized scheduling unit. The optical network node structure proposed by the present invention includes a centralized scheduling unit, and the centralized scheduling unit includes a large-capacity transparent cross unit (Transparent-XC) and one or more dedicated cross units (Dedicated-XC) connected to the transparent cross unit. The transparent cross unit has the ability to cross dispatch all types of services, and the dedicated cross unit has the ability to handle one or more services. In the direction from the customer side to the line side, a variety of different customer-side signals are processed by the customer-side business processing unit and then input to the transparent ...

Abstract

Being as centralized dispatching unit, the disclosed dispatching unit is composed of a transparent cross unit in large capacity, and one or more dedicated cross units connected to the said transparent cross unit. Accessing service, the transparent cross unit in large capacity carries out cross configuration directly or dispatches the service to connected dedicated cross units for further processing based on configuration needed by accessed service. Being dispatched to required output port, the processed signal is sent to service process unit and WDM process unit for subsequent process. The method realizes syncretizing between original independent SDH and OTN equipment so as to be suitable to application scene of coexisting voice service and data service in larger granule. Features are: unitive bus architecture can be configured to different combinations in order to suit different needs of users; syncretizing SDH/SONET system and WDM system to implement unitive management.

Description

technical field [0001] The present invention relates to the optical transmission network in the communication technology, especially for designing a node structure, equipment and service scheduling method for the metropolitan area and core layer optical transport network, using the node structure, equipment or service scheduling method to realize different levels and different Business scheduling for application requirements. Background technique [0002] With the development of communication technology, the capacity of the transmission system is constantly increasing. For SDH / SONET (Synchronous Digital Hierarchy / Synchronous Optical Network) technology, the transmission capacity has increased from the initial 51Mbps to 155Mbps, 622Mbps, 2.5Gbps and 10Gbps, and 40Gbps also Gradually commercialized. At present, the transmission network mainly adopts SDH / SONET as the foundation, which is used to bear voice, data, video and other services. As broadband services gradually enter...
