智慧园区通信网络系统总体设计
Overall Design of Communication Network System for Smart Park

结合标准化体系架构、全面化系统组成、精准化技术指标的需求分析，综合考虑网络结构、网络地址、网络互联、网络策略、网络管理、网络可靠性，总体设计一套标准规范统一、组织管理便捷、体系保障可靠、信息收发具有低时延和高带宽的通信网络系统，作为基础平台和数字动脉更好地服务于园区智慧建设。按照信息系统技术体系，为了实现位置不同、功能独立、管理分散的智慧园区业务资源交互共享，通信网络系统总体设计中的网络结构包括核心层、汇聚层、接入层，网络地址包括业务地址、管理地址、互联地址、组播地址，网络互联包括物理接口、线缆连接、通信路由，网络策略包括QoS策略、VLAN划分、安全防护，网络管理包括拓扑显示、远程支持、性能评估、资源统计、故障分析，网络可靠性包括设备级可靠性、链路级可靠性、网络级可靠性。
Based on the demand analysis of the standardized system architecture, comprehensive system composition, and precise technical indicators, and taking into account the network structure, network address, network interconnection, network strategy, network management, and network reliability, a communication network system with unified standards and norms, convenient organization and management, reliable system guarantee, and low latency and high bandwidth for information transmission and reception is designed as a basic platform and digital artery to better serve the intelligent construction of the park. According to the information system technology system, in order to achieve the interaction and sharing of business resources in the intelligent park with different locations, independent functions, and decentralized management, the overall design of the communication network system includes the core layer, aggregation layer, and access layer in the network structure, business address, management address, interconnection address, and multicast address in the network address, physical interface, cable connection, and communication routing in the network interconnection, QoS strategy, VLAN division, and security protection in the network strategy, topology display, remote support, performance evaluation, resource statistics, and fault analysis in the network management, and equipment-level reliability, link-level reliability, and network-level reliability in the network reliability.
