Embodiment Construction

[0024] figure 1 What is shown is the original backup system using the PCI bus. The communication between the main card and the line card is through the parallel PCI bus, which makes the design of the backplane complicated, the load capacity of a set of PCI bus is limited, and the work efficiency is reduced.

[0025] figure 2 Among them, the system described in the present invention includes not only the main card 30 and the line card 10, but also a core Ethernet switching module 20, and the communication connections between the above three are all performed through the Ethernet bus. The core Ethernet switching module 20 serves as a core switching circuit, realizing fast and non-blocking data interaction between each line card 10 and the main card 30 . The main card 30 then includes an Ethernet interface 301 for data transmission and reception, a main card processor 302 and a main card storage area 303 for storing data, and the Ethernet interface 301 and the main card storage...

Abstract

The back-up system based on fast Ethernet bus includes main card, N line cards, kernel Ethernet exchange module, through which the line cards are connected to the main card, and Ethernet bus for interacting information between the main card and the kernel Ethernet exchange module and between one of the line cards and kernel Ethernet exchange module. The present invention is used in the back-up and rearrangement of both hardware and software during inserting and withdrawing line card and in case of failure. The present invnetion is used to replace parallel bus for the information interaction and can simplify back board design, raise the anti-jamming capacity and increase the transmission distance. The present invention adopts spot-to-spot connection mode to ensure the simultaneous data interaction between each of the line cards and the main card.

Description

technical field [0001] The invention relates to the communication field, in particular to a backup system for large-scale network end equipment. Background technique [0002] In large-scale communication systems, such as program-controlled switches, in order to ensure long-term uninterrupted work of the equipment, the hardware and software of the system have adopted active-standby redundancy technology to realize hot backup and switching. The so-called hot backup of hardware refers to providing at least one backup board for a certain board of the system to avoid a single point of failure of the hardware; hot backup of software refers to that some software of the system runs on two boards, and continuously The mutual backup of software data can be carried out in a timely manner to ensure that if there is a problem with the software of one board, the other board can be remedied in time. Generally, the hot backup of hardware and software is closely combined and indispensable. ...
