With the development of the Streaming media, the data transmission based network video is increasing. Moreover, the time-varying traffic volume of communication network leads to traffic congestion in the peak transmission period and under utilization of communication resources in the low peak transmission period. coded caching is a technology to solve the mismatch between data transmission services and communication resources. This technology can make use of the communication resources in the low peak period as much as possible to reduce the traffic congestion in the peak period, so as to improve the transmission efficiency of the communication system as a whole. For the centralized coded caching model, an array called placement delivery array (PDA) can describe the centralized coding cache scheme. Aiming at the centralized coded caching model, this paper constructs a class of PDA by using some methods based on combinatorial design.
