Embodiment Construction

[0016] A kind of concrete steps of the Ethernet redundant backup method based on double blind hole VPX backplane are:

[0017] The first step is to build an Ethernet redundant backup system based on the double blind hole VPX backplane

[0018] Ethernet redundancy backup system based on double blind hole VPX backplane, including: backplane module, switching module, front board and rear board.

[0019] The switch module runs on the front board and the rear board, and both the front board and the rear board are placed on the backplane module.

[0020] The function of the backplane module is to realize bus interconnection and redundant backup of Ethernet bus;

[0021] The functions of the switch board module are: realize Ethernet switching;

[0022] Step 2 The backplane module completes the Ethernet bus interconnection

[0023] The backplane module determines the via holes that use the Ethernet signal on the backplane printed board as double-sided blind holes, so that the via h...

Abstract

The invention discloses an Ethernet redundant backup method based on a double-blind-hole VPX backplane. The method is realized through an Ethernet redundant backup system based on the double-blind-hole VPX backplane, wherein the Ethernet redundant backup system comprises a backplane module, a switching module, a front plugboard and a rear plugboard. Ethernet bus interconnection is completed by the backboard module, and Ethernet network exchange is completed by the exchange module. According to the invention, the number of the Ethernet buses is increased, and the number of the Ethernet buses can be doubled, so redundant backup is realized.

Description

technical field [0001] The invention relates to an Ethernet redundancy backup method of a VPX architecture, in particular to an Ethernet redundancy backup method based on a double-blind-hole VPX backplane. Background technique [0002] The bus technology based on the VPX hardware architecture has been widely used. As a commonly used bus, the Ethernet bus plays an important role in the VPX architecture. In the past, the VPX backplane printed board used through holes. Such a printed board hole can only Pass one signal, the backplane conforms to the VITA46.0 standard, and defines a maximum of 32 differential signals for each of the J1 and J2 connectors. The swapped front board and the swapped rear board cannot achieve redundant backup, and the swapped rear board only serves as an Ethernet Network port export function. Contents of the invention [0003] The purpose of the present invention is to provide an Ethernet redundancy backup method based on a double-blind-hole VPX bac...
