Title: CONTENT DISTRIBUTION METHOD AND DEVICE FOR CLOUD COMPUTING SYSTEM, COMPUTING NODE AND SYSTEM
Abstract:
Provided are a content distribution method and device for a cloud computing system, a computing node and a system. The method comprises: receiving a content distribution instruction, the content distribution instruction comprising an identifier of content to be distributed and a distribution target node list, and the distribution target node list comprising an identifier of at least one distribution target node; according to physical networking topology, the state traffic of each node in the system and the distribution target node list, generating a content distribution path, the content distribution path being a one-way chain distribution path composed of a head node and at least one distribution target node; and sending a content distribution message to the at least one distribution target node. This method can ensure that the number of nodes connected to each node in the content distribution path is controlled by a distribution controller; therefore, the balance of the access bandwidth of each distribution target node can be realized. Moreover, it can also be ensured that the content distribution path generated each time content is distributed is the optimal distribution path.
