背景
随着社会的发展，企业信息化建设的推进，全国各大中型企业基本上都有了自己的网络，作为医院的决策者们来说，建立高速的网络，使信息流通更快速，将医院建成信息化的高效的医院，使医院立于不败之林。由于邳州人民医院的网络业务量并不大，主要应用是医院内部的信息传递，除此之外，Http、Ftp、Email便是医院与Internet连接的最大流量了。从技术上讲应该采用标准、开放、可扩充的、能与其它厂商产品配套使用的设计。根据用户的总体需求，结合对应用系统的考虑，我们提出网络系统的设计的原则是：可靠的技术选型、标准的体系结构、1000M骨干网、安全性较高、运行性能可靠以及遵循面向应用，注重实效，急用先上，逐步完善的原则。
- 实用性：根椐应用系统的要求确定整个系统的结构，即从系统功能和信息需求出发，拟建系统的结构必须满足系统的传输能力要求、信息安全要求、人机交互能力要求、信息处理要求等；
- 先进性：以先进、成熟的网络通信技术进行组网，并能确保网络技术和网络产品几年内不落后；
- 可靠性：系统必须可靠运行；
- 开放性：选择的产品应具有好的互操作性和可移植性，并符合相关的国际标准和工业标准；
- 可扩充性：系统是一个逐步发展的应用环境，在系统结构、产品系统、系统容量与处理能力等方面必须具有升级换代的可能，这种扩充不仅能充分保护原有资源，而且具有较高的性能价格比,使整个网络系统是可扩展的，便于系统升级，改装；
- 可伸缩性原则：网络的建设是一项持续性的系统工程项目，坚持网络建设规模的可伸缩性原则，将使得网络的建设费用降低，避免不必要的浪费，也体现了网络建设的灵活性；
- 安全性：信息系统安全问题的中心任务是保证信息网络的畅通，确保授权实体经过该网络安全地获取信息，并保证该信息的完整和可靠。网络系统的每一个环节都可能造成安全与可靠性问题。
