随着“互联网+”时代的到来,产业园区为了便于管理均组件了功能完善的局域网。但是,由于产业园区引入的政企单位较多,分布也较为复杂,对通信网络的需求各异,因此亟需引入先进的局域网拓扑架构,构建一个三层的网络架构,将互联网划分为核心层、汇聚层和接入层,每一层都通过接口进行连接和通信,确保局域网结构简单,升级和维护方便,并且主干网络采用千兆以太网,提供更高的带宽资源,为产业园区提供强大的通信服务功能。
With the advent of “Internet + ” era, the industrial park has all-in-one LAN with complete functions for easy management. However, due to the large number of government and enterprise units introduced in industrial parks and the more complicated distribution and the different demands on communication networks, it is imperative to introduce advanced LAN topology to build a three-tier network architecture that divides the Internet into core layers , Convergence layer and access layer, each layer through the interface to connect and communicate to ensure that the LAN structure is simple, easy to upgrade and maintain, and the backbone network using Gigabit Ethernet, providing higher bandwidth resources for the industrial park to provide a strong Communication service function.
