Fairness scheduling device and method for multi-modal service traffic

Abstract

The invention belongs to the technical field of multi-modal networks, and particularly relates to a fairness scheduling device and method for multi-modal service traffic. The device comprises a modal classifier, a multi-modal queue, a multi-modal exchange scheduling center and an exchange structure, wherein the modal classifier identifies service traffic of different modals and sends the service traffic into different modal queues; the multi-modal queue bears different modal service traffic, each queue is identified as a class of modals, and the characteristics of the modal queues are uploaded to the multi-modal exchange scheduling center; the multi-modal exchange scheduling center is used for counting the characteristics of each modal queue, formulating an exchange scheduling strategy adaptive to the multi-modal service traffic, and loading the exchange scheduling strategy to the exchange structure; and the exchange structure receives the exchange scheduling strategy output by the multi-modal exchange scheduling center, executes exchange scheduling logic, opens a corresponding modal queue and outputs a service traffic. According to the fairness scheduling device and method, the fairness exchange scheduling among the multi-modal service traffic is ensured while the multi-modal service quality is met.

Description

technical field [0001] The invention belongs to the technical field of multimodal networks, and in particular relates to a fair scheduling device and method for multimodal service flows. Background technique [0002] After decades of rapid development, the Internet has increasingly become an important part of the national information infrastructure. With the diversified growth of Internet business traffic and the continuous expansion of network capacity, there is an urgent need for key technologies supporting the network to keep pace with the development of the Internet. At present, network nodes (routers, switches, etc.) are gradually becoming the key factors restricting the development of network infrastructure. Switching structures and scheduling algorithms are used as modules of network nodes to study hybrid switching technologies that support high bandwidth, multiple ports, and strong scalability. It is one of the important topics of bandwidth network at present. Due ...
