Problems solved by technology
For example, a DVD movie has a data volume of 4GB. If the system stores all the movies that may be on-demand in the local server, the storage cost will be quite expensive and it is not feasible. Treat differently according to the degree of popularity
Therefore, how much to store and how to store is also a problem that the load balancing mechanism needs to solve. However, there has been no good solution to this problem

The invention discloses a 3Tnet-based video-on-demand load balancing method. The method comprises the following steps of: receiving a video-on-demand request of a user by a central dispatcher; judging the type of the video-on-demand request, wherein the type of the video-on-demand request includes a video-on-demand request to the hot broadcast films and a video-on-demand request to the cold broadcast films; calculating the current load data of the video-on-demand streaming medium server MS-VOD storing all of the films corresponding to the video-on-demand request; sorting according to the load data; and, according to the sorting result, allocating at least one MS-VOD to provide service on the basis of the set probability. The technical scheme can fulfill the aims of balancing the data flow and fully utilizing the system resource.
Description
technical field [0001] The invention relates to the technical field of digital home and network, in particular to a load balancing method of video-on-demand based on 3Tnet. Background technique [0002] With the rapid development of communication network technology, people's demand for communication services has gradually changed from voice to comprehensive demand for data, images and voice, and strive to have a credible, safe and reliable network environment. Traditional communication networks have become increasingly It is becoming more and more difficult to meet the growing demand. New networks are required to provide a trusted, safe, and reliable network environment and provide rich voice, data, image, and multimedia services. The future network will be a low-cost access, universal 3Tnet (high-performance broadband information test network) emerged as the times require. It fundamentally breaks through the service concept and technical limit of the traditional network sy...
