<strong>Named Data Networking in Local Area Networks</strong>

時間：2017年9月29日 地點：九龍湖計算機樓313

報告簡介：

The Named Data Networking (NDN) is a new Internet architecture that changes the network semantic from packet delivery to content retrieval and promises benefits in areas such as content distribution, security, mobility support, and application development. While the basic NDN architecture applies to any network environment, local area networks (LANs) are of particular interest because of their prevalence on the Internet and the relatively low barrier to deployment.
In this presentation, I first introduce NDN-NIC, a network interface card that performs name-based packet filtering, to reduce CPU overhead and power consumption of the main system during broadcast communication on shared media. Then I present a secure and efficient self-learning strategy for switched Ethernet, which discovers available contents via occasional flooding, so that the network can operate without manual configuration, and does not require a routing protocol or a centralized controller.
命名數據網絡（Named Data Networking, NDN）是一種新型互聯網體系結構。傳統IP網絡提供數據包傳輸服務，而NDN網絡提供了一種數據内容獲取的網絡語義。NDN網絡在内容分發、内容安全、移動性支持、以及應用程序開發等方面具有優勢。NDN的基礎架構适用于所有的網絡環境，但是我對局域網特别感興趣，因為局域網是互聯網的重要組成部分，而且在局域網中部署NDN的門檻比較低。
在這個演講裡，我首先介紹NDN-NIC，一種可以過濾NDN報文的網絡适配器，在局域網廣播通訊時降低計算機的CPU占用與能耗。然後我展示一個安全而高效的自學習轉發策略，通過廣播少量的報文令網絡學習到内容發布者的位置，從而使得NDN局域網可以無配置運行，既不需要路由協議、也不需要集中式的控制器。
