隨著近幾年網路迅速發展，使用者的增加伴隨行動裝置、物聯網的高速成長，Named Data Networking(NDN)的提出使得消費者發出資料的請求時，有機會透過儲存在路由器內的快取在路徑上就完成，可以有效地減少延遲。而在Information Centric Networking(ICN)的概念中，任何資訊都可以被命名後在網路上傳遞，可以利用此特性，服務更靠近邊緣的消費者，需求可以更快速滿足。

我們提出的Named Service Networks(NSN)將服務的映像使用NDN傳遞，能夠自動的選擇和替換服務，由距離、受歡迎度、時間和資源多個因素計算分數來決定是否將服務緩存在路由器上，提供最多服務且最高的命中率，減少網路上冗余的副本數量。並且使用了真實的拓墣評估，顯示出我們的方法的確優於傳統的快取策略。

With the rapid development of the Internet in recent years, the increase in users has been associated with the rapid growth of mobile devices and the Internet of Things (IoT). The proposal of Named Data Networking (NDN) allows consumers to send requests for data to be completed on the path through the cache stored in the router, which can effectively reduce delays.
In the concept of Information Centric Networking (ICN), any information can be named and delivered on the network, and services can take advantage of this feature to be closer to the consumers at the edge, so that the demand can be completed faster.

Our proposed Named Service Networks (NSN) delivers the service image using NDN, and calculates scores based on distance, popularity, time and resources to decide whether to cache the service on the router, with the goal of automatically selecting and replacing services, providing the most services with the highest hit rate, and reducing the number of redundant copies on the network. Moreover, real topology evaluation is used to show that our approach is indeed better than the traditional caching strategy.
