<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在一所校园内,总有一部分区域是有线网络<span style="color: black;">不可</span><span style="color: black;">触及</span>的范围,<span style="color: black;">倘若</span>强行<span style="color: black;">部署</span>有线网,后果非常严重。<span style="color: black;">因此</span>,在上面<span style="color: black;">说到</span>的这些<span style="color: black;">地区</span>需要<span style="color: black;">部署</span>无线局域网,<span style="color: black;">才可</span>让<span style="color: black;">全部</span>校园都被网络覆盖。当然<span style="color: black;">咱们</span><span style="color: black;">亦</span><span style="color: black;">不可</span>在一所高校内<span style="color: black;">所有</span><span style="color: black;">部署</span>无线局域网,毕竟无线局域网的数据传输速度较慢,并不适合<span style="color: black;">有些</span>高带宽业务的处理。<span style="color: black;">因此呢</span>,一所校园的校园网应该是一个有线、无线网络的有机结合。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">校园网设计采用“单核心单链路”架构,分为核心层、接入层。采用“万兆核心、千兆接入”的建设思路,核心与接入之间采用千兆连接,所有接入交换机千兆到桌面,校园网整体建设为全千兆网络。</span></p>
