近年網路技術的快速發展，常見的Client/Server網路架構難以負荷日益漸增的使用者數量，為解決此問題，訊息中心網路(Information-Centric Network, ICN)的架構因此被提出，以符合眾多使用者的需求。訊息中心網路為一新型態的Client/Server網路，透過置入多個伺服器於網路中與ICN的資料命名技術，將可提升網路傳輸效率與提升所能承受的使用者數量。而為了提升網路應用服務品質，軟體定義網路(Software-Defined Networking, SDN)技術的應用逐漸提高，透過其控制層(Control Plane)與資料層(Data Plane)的分離，使管理者更易於控制網路。結合ICN網路架構與SDN的北向介面(Northbound Interface, NBI)進行網路環境建置，並透過Data Center Manager來實現Content Server與Cache Server的工作分配、系統監控、負載控制與內容配置等，藉此達到ICN網路的負載降低與提升整體運作效能，最後透過SDN Controller進行路徑配置。
本研究致力於軟體定義訊息中心網路之可適性內容管理機制研究，提出一Data Center Manager於ICN網路中，並由Data Center Manager中的各個模組進行工作指派、資源調配與負載控制的規劃，使網路中的Server能處於最佳運作效能，藉此打破傳統Client/Server網路所遇到的瓶頸。本研究針對工作分配與負載控制模組進行研究分析。首先，針對提出之負載控制進行分析，於負載量上設立門檻值進行機制研究，根據本研究結果顯示，負載控制能有效的監控負載過量的Server，配合工作指派模組進行負載的分擔，使超載的Server負載值降低至非超載狀態。

With the rapid development of the Internet, the most common network architecture is Client/Server which is not afford to the growing of users. In order to solve this issue, Information-centric networking (ICN) was developed to satisfy the users’ requirements and to reduce the loading of server. ICN is a new kind of Client/Server network. By insert several servers in network environment and architecture of ICN which is based on named information (or content or data) that can comes with potential for a wide range of benefits such as promote the delivery speed and ability to accommodate large number of user. Software-Defined Networking (SDN) used the centralized control architecture is different from the traditional network, which the control planes and data planes are decoupled. SDN allows the network to be configured and managed more flexible and programmable.
This work combines architecture of ICN and Northbound Interface (NBI) of SDN to establish network environment. The Data Center Manager provides several functions, such as job distribution, system analysis, loading control and content deployment. And the route path is planned by SDN Controller. This work develops a Data Center Manager in Software Defined Information Centric Networking (SDICN) for solve the problem of traditional Client/Server network. It is focus on job distribution and loading control function. First, the system calculates some variables that must be calculated to make the decisions to assign server. Second, set the threshold of the utilization state and analysis the load value of servers. Then, according the results to allocating server to clients. The results demonstrate that the server which is heavy load can be controlled until its loading is below the threshold. The system assigns the job to the other server which utilization is at normal level.
