| With the rapid development of the Internet, the problems of TCP/P network architecture in resource allocation, network control and many other areas are also becoming increasingly prominent, therefore, researchers from the further network research areas proposed to redesign the network and have promoted a number of highly important and significant research projects. Among them, the "content center network"(Content Centric Networking, CCN) is one of the most promising architectures for the further network. The key idea of CCN is content-based naming, namely the users will obtain the target content not based on the data address, but on the data name. CCN is originally designed to be a pull-based networking, that is, in order to obtain the target content, an interest packet (Interest) must be sent over the network to get the data packet (Data) with the same name. In a word, CCN is a user-driving-network.However, many applications like mail systems and RSS reading are push-based and the service provider will directly send the contents to the users once they complete the registration.As video business has become one of the dominating network applications, to optimize the universality of the CCN networking, it has to support the video service with high efficiency. Confined by the content-obtaining approach of the CNN networking, the service providers can only send out the data packet to the users after having received the corresponding interest packet. During this process, the interest packet can be lost or delayed for a long time caused by reasons like instable networking, thus the users will not be able to access the contents timely and their experience with the service will be negatively impacted. To address the shortage of the CCN live broadcasting system, in this paper by combining the existing Push technology, we have established the Push-living-based strategies, and further proposed the solving schemes for Push technology-based CCN network broadcasting system. |
