摘要:随着世界的信息化技术、计算机网络技术的不断发展,银行信息化水平也应该随着大时代的环境而不断提高,同时银行网络用户数量和网络应用的种类也开始不断的增加,从而使网络的带宽和安全问题日渐成为银行信息化发展的瓶颈,因此,如何在现有的网络基础架构之上,构建出一个高安全性、高可用性、高效性、高扩展性网络系统是本文主要解决的问题。

  本文首先对农村信用社的网络系统现状进行分析,然后提出了现有网络系统的主要问题及新建网络的设计思想,最后设计出具体的网络改造实施方案。方案中通过替换交换机来提升核心设备交换能力并且核心交换机之间运用链路捆绑技术和热备份冗余协议来实现高效性和高可用性。在核心交换机和路由器之间部署动态路由协议OSPF来实现动态学习和通告路由。在安全性方面,使用VLAN技术,逻辑上隔离办公网,业务网以及监控网,同时增加防火墙来进一步提升整体网络的安全性。

关键词 网络改造;安全;路由;VLAN

 

Abstract:With the development of the world of information technology and  Internet technology  , the level of banking information should also continuously improved by the era of the environment  , while the number of bank network users and the types of network applications also began to increase , so the network bandwidth and security issues is becoming a bottleneck in the development of banking information , and how on top of existing network infrastructure to build a high- security , high availability , high efficiency , high scalability network system is this paper is a mainly problem to solve.

   This article is firstly to analysis of the status of the network system of rural credit union , and then put forward the thinking of the main problems of the existing network system and design the new network system , then finally design a specific network transformation embodiment . This proposal is mainly program by replacing the core switch to enhance the exchange capacity of the core equipment and the use of the link bundling technology and hot standby redundancy agreement between core switches to achieve high efficiency and high availability . Deployment of a dynamic routing protocol OSPF between core switches and core routers to dynamically learn and advertise routes . On the security , the use of VLAN technology , the logically isolated office network and service network , as well as the monitoring network , to further enhance the overall security of the network at the same time increase the firewall .
