Study of Content-Based Distribution Network Architecture

Because different types of information contents have different requests for the QoS of transmission, the architecture of content-based distribution network (CBDN) is put forward in this paper. The network topology of CBDN is introduced. The working principle and key technologies of the architecture is explained in detail. According to the different requirements of the different types of information content, it adopts different transmission policy to schedule different transmission resources, so that the information, especially the survivable information are transmitted to the key locations in demands on time, on quantity and reliably.
