命名数据网络（named data network，NDN）是正在研究中的以数据为中心的下一代互联网络，而路由转发机制是NDN的核心问题。为了更好地提高网络的整体性能，提出了端口优先级路由策略，基于蚁群优化算法，根据每个路由接口的转发概率分别设置转发接口优先级，引入兴趣包的错误反馈信息包，降低用户的请求失效率。实验结果表明，端口优先级路由策略在网络平均延迟和数据包投递率方面优于邻居缓存路由（neighbor cache explore routing， NCE）策略，验证了端口优先级路由策略在NDN网络中的有效性。
命名數據網絡（named data network，NDN）是正在研究中的以數據為中心的下一代互聯網絡，而路由轉髮機製是NDN的覈心問題。為瞭更好地提高網絡的整體性能，提齣瞭耑口優先級路由策略，基于蟻群優化算法，根據每箇路由接口的轉髮概率分彆設置轉髮接口優先級，引入興趣包的錯誤反饋信息包，降低用戶的請求失效率。實驗結果錶明，耑口優先級路由策略在網絡平均延遲和數據包投遞率方麵優于鄰居緩存路由（neighbor cache explore routing， NCE）策略，驗證瞭耑口優先級路由策略在NDN網絡中的有效性。

Named data network(NDN)is the next generation which is centered on data. Routing mechanism is the core issue of NDN. In order to better improve the overall function of network,this paper puts forward the port-priority-based routing strategy. On the ba?sis of ant colony optimization,it respectively sets up and forward the interface priority for the purpose of introducing the error feedback packets with interest packet and reduce the users’failure rate of request. The result of the experiment shows that port-priority-based rout?ing strategy is better than neighbor cache explore routing(NCE)on the aspects of network average delay and packet delivery ratio. It also proves the effectiveness of port-priority-based routing strategy in NDN.
