Problems solved by technology

For the SRIO network used by the SDR system, it is usually composed of nodes and switches. When some nodes or switches fail, the switches may not be able to exchange data packets normally, resulting in the inability to communicate between nodes, resulting in the failure of the entire network. , even cannot be restored online, and once this happens, it will cause the failure of the whole machine function

Abstract

The invention discloses a dual-SRIO network backup system oriented to a software radio system, which includes two GSIMs and several functional modules. Both the GSIM and the functional modules contain an SRIO switch, and one end of the SRIO switch inside the functional module is connected to the SRIO of the two GSIMs. The other end of the switch is connected to each computing node of this module, and the backup GSIM replaces the main GSIM after the main GSIM fails. The invention realizes that when the main network breaks down, the software radio system can switch to the backup network in time to prevent function failure.

Description

technical field [0001] The present invention relates to a high-speed bus network redundancy design in a software defined radio (Software Defined Radio, hereinafter referred to as SDR) system, and a master-standby switching method of a bus network, especially an SDR system based on a software communication architecture (Software Communication Architecture, hereinafter referred to as SCA) A method for switching between dual high-speed serial bus (Serial RapidIO, hereinafter referred to as SRIO) networks. Background technique [0002] The SDR system enables the radio frequency equipment to have reconfigurable capability through the combination of hardware and software. On the premise of not changing the hardware, different radio frequency functions can be realized by changing the software. It has changed the traditional concept, brought far-reaching influence on wireless communication from various aspects such as softwareization, intelligence, generalization, personalization an...
