Load balancing method and device based on queue overhead under edge streaming media

Abstract

The invention provides a load balancing method and device based on queue overhead under edge streaming media, and the method comprises the steps: obtaining an access request sent by a user, and analyzing a channel and a code rate of a to-be-accessed live broadcast stream from the access request; if the channel of the to-be-accessed live stream is not matched with the channel served by each edge server in an edge server cluster at the current moment, determining the channel of the to-be-accessed live stream according to the CPU load overhead and bandwidth load overhead occupied by all users served by each edge server at the current moment; obtaining the total overhead queue length of each edge server at the current moment; and selecting a target edge server with the minimum total overhead queue length from the edge server cluster to serve a user, so that the target edge server transmits the to-be-accessed live broadcast stream to the user according to the channel and the code rate of the to-be-accessed live broadcast stream. According to the invention, load balancing is improved, and better service experience is provided for users.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a load balancing method and device based on queue overhead under edge streaming media. Background technique [0002] With the rapid development of the live broadcast business, the users of various crowdsourced live broadcast services are growing exponentially, which undoubtedly poses a challenge to the live streaming technology. The live broadcast technology is accelerated from the very beginning of CDN (Content Delivery Network, content distribution network), which brings good experience to users through load balancing and cache optimization; CDN has two parts: global load balancing and local load balancing, which can reduce delay and improve service quality and reduce the load pressure on the core network. However, the problems of high cost, limited storage space, and low scalability are difficult to solve. Later, in order to solve the above problems, the conce...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a load balancing method and device based on queue overhead under edge streaming media, which is used to solve the problem of the load and load of the edge server serving users when the client independently selects the code rate according to the state of the local network in the prior art. The transmission cost will also change randomly, resulting in the inability to provide users with a better service experience adaptively, and it is also impossible to guarantee the load balance of the edge server in real time, so as to improve load balance and provide users with a better service experience
