摘要
通过分析我院传统的网络拓扑结构存在的不足,采用环网保护技术、链路聚合技术和动态路由协议对我院新门急诊大楼的网络进行优化设计。新门急诊大楼网络整体设计采用主流核心层、汇聚层、接入层三层网络架构。核心交换机采用双机组成冗余热备结构,核心交换机与汇聚交换机之间采用双千兆光纤链路组成环形拓扑,满足了新门急诊大楼现有业务对网络的需求,并具有很好的可扩展性。
By analyzing the shortage of traditional network topology in our hospital, this paper demonstrates the optimal design of the network of the new outpatient and emergency building by applying technologies of ring protection, link aggregation and dynamic source routing protocol. The design of the new building adopts three-tier network architecture of core layer, convergence layer and access layer. The core switch uses redundant heat standby structure with double-unit, and the ring topology is composed with double-GigaByte optical fibre link between core switch and convergence switch. It can completely satisfy the requirement of the hospital business, and has good scalability, and can upgrade with the technology development.
