Embodiment Construction
[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0033] The purpose of the present invention is to propose a method for pre-publishing video services in the autonomous domain in NDN / CCN. On the basis of improving the universality of NDN / CCN, the method realizes pre-release of video services in NDN / CCN, and utilizes users to request video services. The feature of data continuity is that before the request is issued, the information manager (IM) in the autonomous domain collects the historical request records of the users in the domain. Notify the server in the form of a request packet. The server obtains the push target data through the request packet sent by IM, and actively pushes it to the autonomous domain during the idle period of the network link (such as the early morning period). For example, if an autonomous domain user visits a TV series that updates two episodes a day, and visi...

The invention relates to a method for pre-publishing video services in an autonomous domain in NDN / CCN, and belongs to the technical field of Internet communication. According to the request history information of the users in the autonomous domain and the request characteristics of the continuity of the video service, the method realizes pre-publishing the data to be requested by the users in the autonomous domain in the next period to the cache nodes in the autonomous domain. Through the information manager (IM) in the autonomous domain to collect and count the historical request information of the users in the domain, the IM obtains the data that the users in the domain want to request in the next cycle through the statistical results, and periodically notifies the server of the data information. The server uses the idle period of the network link to pre-publish the data to the node set cache to meet the requests of users in the domain in the next cycle. The invention utilizes the request information of users in the autonomous domain to release new video content to nodes in the autonomous domain in advance, reduces the user's access delay, avoids congestion during network peak periods, and improves the user's data acquisition experience.
Description
technical field [0001] The invention belongs to the technical field of Internet communication, and relates to a method for pre-publishing video services in an autonomous domain in NDN / CCN. Background technique [0002] With the development of Internet technology, user needs and communication methods have changed, from traditional end-to-end communication methods to content sharing and resource acquisition. Content is the trend of Internet development. Such a development trend makes the traditional TCP / IP network architecture face severe challenges, hinders the development of the Internet, and cannot meet people's needs. In order to break the shackles of the traditional Internet TCP / IP structure, researchers designed a new Internet architecture to completely solve the problems exposed by the current network architecture. Among them, Named Data Networking (NDN) / Content Centric Networking (CCN) is the most representative and promising development in the current new Internet ar...
