Abstract

Disclosed are a child node, father node and buffer method and system for a multi-layer video network. The multi-layer video network comprises at least one father node and a plurality of child nodes connected to the father node. The method comprises: collecting the user request arrival rate for each content in the content set of each child node; and based on the user request arrival rates, the storage capacity and uploading bandwidth of each child node and the size of each content, determining an optimal storage policy and an optimal uploading bandwidth allocation policy of each child node for each content. By means of the above disclosure, the technical solution disclosed by the present invention can fully conserve the network bandwidth and enable cooperation among buffer nodes; in addition, the technical solution is compatible with a heterogeneous network resource environment.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to a child node, a parent node, and a caching method and system for a multi-layer video network. Background technique

[0002] With the rapid development of computer network technology and infrastructure construction, multimedia network services such as high-resolution video on demand provided by multimedia service providers are gradually emerging. These services usually utilize the bandwidth and storage resources in the cache system to provide high-quality and uninterrupted video streams to end users. However, the ever-increasing number of users and higher demands on service quality have also brought great pressure to service providers. The overall bandwidth and storage resources of the video-on-demand system are limited, so service providers have to increase investment in infrastructure construction to meet the growing user needs. In this context, how to effectivel...
