Multimedia Information Publishing Platform based on Server Cluster and Internet of Screens

In this paper, a Multimedia information publishing platform based on server cluster and Internet of screens is proposed, which is composed of four level hierarchical structure, including the screen identification layer, the network transport layer, the service management layer and the publishing application layer. The screen identification layer has realized the internet of screens in which geographically dispersed independent screens are connected to the internet by the customized set-top boxes. The service management layer uses the server cluster to balance the load across the application servers. And the storage cluster is used to storage and manage the promptly increasing multimedia publishing information. Meanwhile MQTT protocol to solve the bandwidth bottlenecks in constrained environments such as internet of things. The paper has designed and realized a prototype SzIoScreen, and give some related test results.
