Abstract
The invention discloses an Ethernet redundancy backup method based on a double blind hole VPX back plate, which comprises the following steps: the Ethernet redundancy backup system based on the double blind hole VPX backboard is built by the backboard module, the exchange module, the front plugboard and the rear plugboard. The back board module completes Ethernet bus interconnection, and the exchange module completes Ethernet network exchange. The invention improves the number of the Ethernet buses, and can increase the number of the Ethernet buses by 1 time, thereby realizing redundant backup.
Description
Technical Field
The invention relates to an Ethernet redundancy backup method of a VPX framework, in particular to an Ethernet redundancy backup method based on a double blind hole VPX back plate.
Background
A bus technology based on a VPX hardware architecture is widely applied, an Ethernet bus is used as a common bus and plays an important role in the VPX architecture, a conventional VPX backboard printed board uses through holes, so that only one signal can be taken by a printed board hole position, the backboard accords with VITA46.0 standard, at most 32 differential signals of J1 and J2 connectors are defined, redundant backup cannot be realized by a front exchange plugboard and a rear exchange plugboard, and the rear exchange plugboard only plays a role in leading out an Ethernet port.
Disclosure of Invention
The invention aims to provide an Ethernet redundancy backup method based on a double blind hole VPX back plate, which solves the problem that the prior front and rear switch plugboards can not be redundantly backed up.
The Ethernet redundancy backup method based on the double blind hole VPX back plate comprises the following specific steps:
first step builds ethernet redundancy backup system based on two blind hole VPX backplanes
Ethernet redundancy backup system based on two blind hole VPX backplanes includes: the system comprises a back board module, a switching module, a front plug board and a rear plug board.
The exchange module runs on the front plug board and the rear plug board, and the front plug board and the rear plug board are both arranged on the back board module.
The function of the back plate module is as follows: realizing bus interconnection and redundancy backup of an Ethernet bus;
the function of the exchange board module is: realizing Ethernet exchange;
second step of the backplane module completing the Ethernet bus interconnection
The backplane module determines the via hole of the backplane printed board using the Ethernet signal as a double-sided blind hole, so that the via hole at a single position runs two paths of signals, and the Ethernet bus realizes redundancy backup.
The third step is that the exchange module completes the Ethernet network exchange
The exchange module utilizes the Ethernet interfaces with the same number of the front plugboards and the rear plugboards to carry out network exchange, thereby realizing the complete redundancy backup on the function.
Therefore, Ethernet redundancy backup based on the double blind hole VPX back plate is realized.
The invention improves the number of the Ethernet buses, and can increase the number of the Ethernet buses by 1 time, thereby realizing redundant backup.
