A Priority Allocation Method Based on Bus Access Between Multi-Server Nodes

Abstract

The invention provides a priority allocation method based on bus access among multiple server nodes. Firstly, according to the bus communication requirements of the server nodes, the key physical signals participating in the bus communication logic are grouped and integrated using a programmable logic controller; at the same time, each node is parallelized The initial monitoring of high-speed data transmission; the time sequence of the bus signal, the trigger priority requirements and other actual values ​​are matched with the requirements in the DSP. The principle is that the bus is idle. Nodes are switched and connected sequentially; when the bus is busy, in addition to considering the natural ordering, the judgment of the waiting time is also added, and the nodes with a longer waiting time are given priority to access the bus communication; the time sequence and trigger requirements of each bus signal are adopted. DSP software language implementation; the programmable logic controller transmits the collected bus communication signals to the DSP data processing center, and the DSP judges the actual values ​​such as the time sequence and trigger requirements of the participating signals according to the pre-scheduled requirements, and then gives the judgment Whether it meets the requirements of bus switching and achieves a balanced allocation of resources.

Description

technical field [0001] The present invention relates to the field of computer communication, and specifically uses a priority allocation method based on bus access between multi-server nodes to solve the problem that the server system cannot communicate according to the current node-to-point communication data transmission process between the current server system nodes. , Real-time automatic deployment of computing resources when the bus is idle. The method ensures the real-time performance, reliability and stability of server node communication. Background technique [0002] Today's server systems often require multiple server nodes to cooperate to complete computing tasks, and the data and management channels between multiple server nodes are usually mounted and communicated equally on the bus. The server needs long-term uninterrupted operation and stability, and the reliability requirements of node communication are constantly increasing. In order to ensure the stable d...
