基于云计算的园区网群设计

Design for Campus Network Group Based on Cloud Computing

建造校园网群的目的是:提供单一、通用和公共的网络构架,以高速有效地传输数据、声音、图像和视频等信息,满足师生的需求。本文介绍了校园网群建设的几种关键技术(包括IP over SDH、IP over WDM和千兆以太网技术)及校园网群信息中心的云计算解决方案,并对它们进行了比较分析,在此基础上,提出了建设校园网群网络系统的核心层、汇聚层、接入层三层结构的层次化设计,以及数据中心分层设计、虚拟桌面方案,并实施于实际的系统中。

The purpose of constructing the campus network group is to provide a single, common and public network architecture to transmit data, voice, image and video information with efficiency and high-speed to meet the needs of teachers and students. This paper describes several key technologies including IP over SDH,IP over WDM and Gigabit Ethernet Technologies and cloud computing solu-tions of information center of campus network group, and makes comparison and analysis on them, On this basis, it proposes a three-layer hierarchical structure design such as core layer, aggregation layer and access layer of campus network group system construction, data center hierarchy design and virtual desktop solution, which is applied to the implementation in practical system.
