Abstract

The invention provides a scheduling method and device. The scheduling method comprises the steps of: receiving a first data packet, wherein the first data packet comprises flow information of a firstdata stream, and the first data stream comprises the first data packet; calculating a first weight value of the first data packet according to the flow information; packaging the first weight value inthe first data packet to obtain a second data packet; and sending the second data packet. The method and the device can be applied to various scheduling strategies, flexible switching of the variousscheduling strategies is achieved, and various service requirements are met.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a scheduling method and device. Background technique [0002] There are various services in the data center network, and different services have different requirements. Some services are sensitive to flow completion time (FCT), such as e-commerce services; some services are sensitive to deadlines (DDL). For example, the back-end data processing service of a bank; some services require fair queuing (fairing queuing, FQ), such as a cloud service leasing service. [0003] In related technologies, different scheduling methods are designed for different services. Among them, for FCT-sensitive services, based on whether the length of the flow is known, the small flow can be placed in the high-priority queue when the length of the flow is known, and the large flow can be placed in the high-priority queue. Exile to a low priority queue. When the length of the flow is unknown,...
