Problems solved by technology

The business data and management data of the above switching boards are generally time-division multiplexed on the same channel, and its stability is relatively poor.
In addition, the management and control protocols of the existing switch boards are mostly self-defined and do not support the standard IPMI protocol, which makes the compatibility of switch boards of different brands poor. sexually restricted

Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention more clear, the high-speed exchange board and control method based on the VPX standard provided in the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] In system applications, data processing modules are usually distributed on different function boards, and different function boards need to frequently exchange data to realize specific business processing functions. At present, for the transmission of large amounts of data, external optical fibers or backplane interconnection methods are not flexible enough, and the backplane connection topology is fixed, it is difficult to meet the needs of multiple signal processing systems, and the system cannot be reconfigured. Although the above problems can be solved by using dedicated switch boards, most of the switch boards based on the VPX standard are custo...

Abstract

The invention relates to a high-speed switch board based on the VPX standard. The switch board can be interconnected with a backboard meeting the VPX standard and implement SRIO switch and Ethernet switch of a function board by using the backboard; the switch board comprises a main control module for managing and controlling the switch board; and a switch module, comprising a high-speed data switch module for implementing high-speed data switch, and an Ethernet switch module for implementing the Ethernet switch, wherein the switch module is connected with the main control module and is managedand controlled by the main control module.

Description

technical field [0001] The invention relates to the technical field of communication calculation and signal processing, in particular to a high-speed switching board and a control method based on the VPX standard. Background technique [0002] With the continuous development of communication technology, the rapidly increasing amount of data has raised the requirements for transmission bandwidth, and also brought rapid progress in high-speed serial bus technology. In order to realize the flexible construction of the topology structure of data interaction, a dedicated switching board is often used to meet the requirements of the multi-signal processing system. [0003] The switching boards in the prior art generally only support one protocol switching, for example, switching based on PCIe, Gigabit Ethernet or 10G Ethernet, or a customized board based on the SRIO protocol. The service data and management data of the above switch boards are generally time-division multiplexed o...
