Embodiment Construction

[0028] see Figure 4 , which is a schematic diagram of the internal board slots of the first embodiment of the data communication device disclosed in the present invention. Both the first main control board 11 integrated with the first service module 111 and the second main control board 12 integrated with the second service module 121 are inserted into the slots of the backplane 10 . If the service modules integrated on the main control board are insufficient to meet the user's service function requirements, service boards 13 can also be inserted separately in other slots of the backplane 10 . The business board 13 mentioned here refers to a traditional business board. It can be seen from the schematic diagram of the slots that since the business modules with business functions are integrated on the main control board, the volume of the entire communication device is smaller under the condition of realizing the same business functions.

Abstract

The disclosed data communication device includes first and second main control boards. Both of first and second main control boards include main control module and service module. Any one of main control modules is electrical connected to the service modules on two main control boards respectively. Main control module in mode of main use can control service modules on different main control boards. Thus, at any moment, service modules on two pieces of main control board (one in mode of main use, and the other in mode of standby) can be utilized simultaneously. Comparing with prior art, the invention raises use ratio.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a data communication device. Background technique [0002] With the development of data communication technology, data communication devices (such as routers, Ethernet switches, etc.) provide more and more functions and higher performance. Although there are many types of data communication devices, in terms of composition and structure, mid-to-high-end equipment is composed of a main control board (main and backup) and a service board. Among them, the main control board is responsible for providing the public functions of the entire device, such as configuration management, routing protocol processing, etc., which is equivalent to the manager of the entire device. The service board is responsible for providing external services, such as interface services (such as Ethernet ports, ATM interfaces) or services with certain special functions (such as network security services, etc...
