Server scheduling method and system, regional dispatching center and global scheduling center

Abstract

The invention provides a server scheduling method and system, a regional dispatching center and a global scheduling center. The server scheduling method comprises the following steps: receiving a service request from a user terminal, wherein the service request carries service type information; and scheduling a server the same as the service type in the region to process the service request of the user terminal, and sending response information of the service request to the user terminal. The technical scheme of the invention establishes a global resource scheduling allocation node, and distinguishes the server types for processing business of different types, thereby ensuring the classroom interaction and live broadcast effect, further accelerating the response speed and improving the user experience.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a server scheduling method and system, a regional scheduling center, and a global scheduling center. Background technique [0002] In the application of video teaching scenarios, the most common ones are classroom interaction and classroom live broadcast. Classroom interaction has strict requirements on real-time performance. The two-way delay is generally required to be within 1.5s. It has high requirements on screen fluency, audio and video synchronization, image quality, and sound noise and echo. Classroom live broadcast requires real-time performance. The requirements are slightly lower, generally acceptable in 5-10 seconds, and there is no echo problem, but the screen fluency and interaction are consistent, as long as the above one or two points are not satisfied, the user will feel uncomfortable and affect the user experience of the product. In most usage sce...

Classroom interaction has strict requirements on real-time performance. The two-way delay is generally required to be within 1.5s. It has high requirements on screen fluency, audio and video synchronization, image quality, and sound noise and echo. Classroom live broadcast requires real-time performance. The requirements are slightly lower, generally acceptable in 5-10 seconds, and there is no echo problem, but the screen fluency and interaction are consistent, as long as the above one or two points are not satisfied, the user will feel uncomfortable and affect the user experience of the product

In most usage scenarios, classroom interaction and classroom live broadcast rely on the public network, which has few resources and many users, such as the famous "last mile" problem, and there are many operators that make up the public network. The current situation of poor network interoperability between operators makes it difficult to perform audio and video interaction and live broadcast on the public network
