Abstract

The invention discloses a data exchange method and system of the node media servers of a content delivery network (CDN). The method comprises the following steps: after starting, the media servers send the corresponding IP addresses and MAC addresses to an exchange controller and also inform the exchange controller when the IP addresses and / or MAC addresses are changed; the exchange controller establishes and updates the media forwarding table of the CDN node according to the received IP addresses and MAC addresses of the media servers, and also updates the media forwarding table in the media servers; when data exchange is performed between the media servers in the node, the MAC address of the target media server is obtained through the local media forwarding table and the IP Encapsulation of the data message is performed. By using the method and system of the invention, the problem that when data exchange is performed between the node media servers in the traditional CDN, data packet flooding may be caused, can be solved.

Description

technical field [0001] The present invention relates to the field of media data interaction, in particular to a method and system for media data interaction between media servers in CDN (Content Distribution Network, content distribution network) nodes. Background technique [0002] With the rapid development of the Internet and multimedia industry, various storage technologies and storage systems have also been developed rapidly. These storage systems provide convenient, fast and efficient storage and access services for massive Internet information and multimedia data information. [0003] As a part of the storage system, the media server is widely used in the servers of CDN services such as IPTV (Internet Protocol Television, interactive network television) system on-demand, and is used for data in a single node (each node provides services for an area or a part of users). storage and reading. With the improvement of user requirements, the amount of data to be stored in...
