Scheduling method for fair round-robin output of switching system based on hardware

Abstract

A switching system fairness cycle output dispatching method based on hardware is used for carrying out reasonable and efficient output dispatching on a plurality of input ports in a switching system, and overcomes the defect that in an existing cycle dispatching output technology, efficiency is low and fairness is poor. According to the method, a multi-bit output application signal with a plurality of bits of binary system values being 1 is converted into a multi-bit output application signal, namely one-hot code with only one bit of binary system value being 1 and the rest of bits of binary system values being 0; then, due to the fact that only one bit of the multi-bit output application signal, namely the one-hot code is 1, an output port only needs to respond to the input port corresponding to the bit 1, and only one input port is selected from the multiple input ports sending the output application signals at the same time to achieve the fair cycle output dispatching process. The switching system fairness cycle output dispatching method is an efficient, fast and quite fair dispatching service method.

Description

technical field [0001] The invention relates to a round-robin-based scheduling strategy technology used in a communication switching system, to be precise, to a hardware-based scheduling method for switching system fairness round-robin output, and belongs to the technical field of digital communication. Background technique [0002] At present, due to the rapid development of computer and its interconnection technology, Ethernet has become the short-distance two-layer computer network with the highest penetration rate so far; and the core part of Ethernet is the switching system. A switching system is a communication system that completes data exchange. With the rapid development of Ethernet, users have higher and higher requirements for network performance, and the influence of switching system on network performance is becoming more and more important. Therefore, it is necessary to improve the scheduling method, one of the important technical components in the switching sy...
