The dilemma will cause many services cannot be used due to limited network bandwidth and the transfer protocol. In order to solve the above problem, scholars have studied and proposed new transport architecture, and Content Centric Network (CCN) is one way to solve. Through data-based network to replace the existing IP address-based transmission. Using name data and content cache to improve network performance, but the data cache scheme is not stable yet. This will result in a waste of memory space, and compression of the other types of data storage space. Therefore cache node selection has become one of the hot topics. This research will present a new cache scheme, by calculating and give the client to the data repository path through router a weight value, and the choice of weights for the cache node. To reduce the client to obtain data the average hop count as its main objective, and at the same time reduces the number of router cache data. So can resolve the current caching scheme caused by the problem of waste and poor efficiency of internet space. This can provide greater flexibility in the use of space resources, and increasing the effectiveness of network transmission. In this paper we use the ndnSIM simulation of the proposed scheme compared with traditional methods. Result display proposed scheme improve the problems posed by the traditional caching scheme, and increase overall network efficiency.
