摘 要
随着新型网络技术的迅猛发展，网络信息技术、网络安全技术、数据备份技术、设备冗余技术以及加密等技术已逐步体现起来。随着校园网需求也就越来越大，所以需要规划建设一个与时俱进并且具备可用性高、冗余能力强的校园网网络，只有这样郑州铁路职业技术学院的网络架构才会越来越安全，防止重要数据被非法泄密。在本文中，将结合当前领先的信息技术来实现郑州铁路职业技术学院园网络设计以及实现的需要。
本文旨在研究与设计郑州铁路职业技术学院的校园网络规划。通过对校园网的需求进行深入分析，提出了一套总体设计方案。该方案涵盖了网络总体架构设计、关键技术的运用、设备选型与配置等多个方面。特别是在校园网络构建中创新性地应用了IPsec VPN技术，实现了校区间的互联与移动办公服务，不仅显著降低了运营成本，还提高了网络服务的效率和可靠性。在仿真阶段，利用华为eNSP软件进行了网络拓扑设计和设备配置，成功实现了校园网的各项功能，包括虚拟局域网VLAN、MSTP多生成树、VRRP虚拟路由器冗余协议、OSPF动态路由、访问控制技术ACL、DHCP、地址转换NAT以及IPsec VPN等配置。本文的研究与实践为铁路职业技术学院校园网络的优化与升级提供了有力的技术支撑。

Abstract
With the rapid development of new network technology, network information technology, network security technology, data backup technology, equipment redundancy technology and encryption and other technologies have been gradually reflected. With the increasing demand for campus network, it is necessary to plan and build a campus network with high availability and strong redundancy ability. Only in this way can the network architecture of Zhengzhou Railway Vocational and Technical College become more and more secure and prevent important data from being illegally leaked. In this paper, the current leading information technology will be combined to realize the network design and realization needs of Zhengzhou Railway Vocational and Technical College Park.
This paper aims to study and design the campus network planning of Zhengzhou Railway Vocational and Technical College. Through in-depth analysis of the needs of campus network, a set of overall design scheme. The scheme covers the overall network architecture design, the application of key technologies, equipment selection and configuration and other aspects. In particular, IPsec VPN technology has been innovatively applied in the campus network construction to realize the interconnection between campus and mobile office services, which not only significantly reduces the operating cost, but also improves the efficiency and reliability of network services. In the simulation stage, the network topology design and device configuration were used with Huawei eNSP software, and successfully realized the functions of campus network, including virtual LAN VLAN, MSTP multi-spanning tree, VRRP virtual router redundancy protocol, OSPF dynamic routing, access control technology ACL, DHCP, address conversion NAT and IPsec VPN configuration. The research and practice of this paper provide a strong technical support for the optimization and upgrading of the campus network of railway Polytechnic.
