The Research Of Digital Home Content Delivery Network

With the development of digital home services industry, digital media services asan important component of the digital home services, has also been considerabledevelopment, but the distribution and sharing of media resources becomes theconstraints of the development of digital media services. The digital home mediaservices to resource distribution network is the network nodes and resources foreffective management and control, the copyright protection of resources, resources inthe family high-speed, and orderly distribution.At present, the media services are mostly implemented by the P2P network andCDN network distribution and sharing of resources, mainly in the following questions:P2P network scalability, resource-rich and rapid distribution, but the lack of effectivemanagement and control of the access node, and easy to form a network flood impacton the backbone network; Resources are spread over a large number of network nodesso can’t guarantee the security of resources. CDN network alleviate the pressure onthe central server through the edge server, but the cost of network expansion is high,and lack of control of network nodes. Are unable to meet the needs of digital homeservices around the above-mentioned problems, this paper presents the contentdistribution network model for the digital home, and its key technologies research,including the following two aspects:1. The proposed digital home content distribution network control andmanagement of digital home-based service platform and family intelligentterminals, existing P2P and CDN integration network model modified for aregional breakdown of the network platform for the efficient control of theterminal, network node control and management of system resources to meetthe requirements of the digital home media network and resource control.2. The proposed digital home content distribution network resources copyrightprotection technology-the system encryption technology. Systemencryption technology to driver layer transparent encryption technology depends on the digital home content distribution network architecture, theresource copyright protection. In architecture, resources transparently for theuser, does not affect the normal use of the resources, once the resources toleave the system, you can’t use.
