Abstract

The invention discloses a cloud video content distribution method and system based on content perception and group purchase strategy. The method includes the following steps: propose a fine-grained video content division method based on content perception to divide video content into different types, propose a group purchase strategy to allow Users form group buying alliances to obtain discounts, generate network topology, generate user requests and form group buying alliances, propose objective functions and constraints, and finally use GLPK to solve them. The cloud video content distribution method based on content awareness and group purchase strategy can effectively reduce the total cost of users under the premise of ensuring user QoS.

Description

technical field [0001] The invention relates to a cloud video content distribution method and system based on content awareness and group buying strategy. Background technique [0002] The emergence of Content Delivery Networks (CDNs) alleviates the occurrence of network congestion and reduces the network traffic in the link. CDNs providers set up servers in different regions and store content that users access multiple times on edge servers. When a user requests network resources, the CDN uses the redirection mechanism to direct the user's request to the local server closest to the user, which not only prevents a large number of users from accessing the source server, causing excessive load on the source server, but also reduces the number of links passed through the network topology. Network traffic, while also reducing the delay and improving the quality of service (Quality of Service, QoS). [0003] With the development of network technology, the emergence of commercia...
