2、网络实验室，分504、508、511三个实验分室。电子楼内有数字媒体实验室、软件工程实验室和电子实验室。三号楼为教学楼，共5层，每层均需配置接入交换机。4) 校区内使用私有地址，外网出口地址为200.100.50.25/29；逸夫楼网络实验室可用地址为一个C类地址，电子楼可用地址为二个C类地址，三号楼可用地址为一个C类地址。5) 校区网络结构参考拓扑如图1所示。图1网络结构参考拓扑图2. 组网和配置1) 拓扑图说明：接入层交换机都选用24口交换机2）设备选型核心交换机：型 号：CISCO WS-C6509-E产品类型：企业级交换机 应用层级：三层 传输速率 ：10/100/1000Mbps 交

3、换方式:存储-转发背板带宽:720Gbps 包转发率 :387Mpps MAC地址表 :64K端口结构:模块化 扩展模块:9个模块化插槽 传输模式:支持全双工选型理由：该交换机工作在三层，适合于核心层使用路由功能。背板带宽720Gbps，适合于核心交换。模块化端口可选光口做链接，以及合适于以后扩充。汇聚交换机：型 号：CISCO WS-C4506-E选型理由：该交换机是三层，适合于汇聚层路由功能。背板带宽100Gps，适合做汇聚层转发速率。模块化结构，适合模块选取和扩充。产品类型企业级交换机应用层级三层传输速率10/100/1000Mbps交换方式存储-转发背板带宽100Gbps包转发率75M

4、pps端口结构模块化扩展模块1个超级引擎插槽数+5个线路卡插槽传输模式支持全双工接入交换机：型 号：CISCO WS-C2960-24TC-L选型理由：接入层交换机工作早二层，该交换机合适。背板带宽4.4Gbps，满足接入层交换速率。价格低廉，可以大量选取和扩充。产品类型智能交换机应用层级二层传输速率10/100MbpsDRAM内存64MBFLASH内存32MB交换方式存储-转发背板带宽4.4Gbps包转发率6.5MppsMAC地址表8K端口结构非模块化端口数量26个端口描述24个以太网10/100Mbps端口，2个两用上行端口传输模式全双工/半双工自适应路由器：型 号：CISCO-2911/

5、K9选型理由： 该路由器企业级路由，支持10/100/1000Mbps自适应，可以满足出 口路由需求。支持ipv4及ipv6。模块化借口便于扩充。路由器类型多业务路由器网络协议IPv4，IPv6，静态路由，IGMPv3，PIM SM，DVMRP，IPSec传输速率：10/100/1000Mbps端口结构：模块化广域网接口 3个其它端口2个外部USB闪存插槽1个USB控制台端口1个串行控制台端口1个串行辅助端口扩展模块1个服务模块插槽数+4个EHWIC插槽2个双宽度EHWIC插槽（使用双宽度EHWIC插槽将占用两个EHWIC插槽）1个ISM插槽2个板载DSP（PVDM）插槽3)原理描述核心交换机

6、与汇聚层之间路由交换采用ospf网络协议，该协议的特点为：a）最大特点就是绝对的无环路：SPF算法保证area内无环路。每个area必须与area 0 相邻，保证了area之间无环路 。所以ospf整体是绝对无环路的。b)快速收敛维护3张表。邻居表（显示邻接关系），拓扑表（列举所有收到的LSA（link state advertisement），是一个LSA数据库），路由表（记录到达某个网段的最佳路径，是由前边2个表算出来的）c)链路通告d)开放式所有厂家都支持，且数据包的格式都通用。便于延展。e)带宽开销少触发式路由更新。ospf交换的是LSA, 不是路由条目。汇聚层划分vlanVLAN的好

7、处主要有三个：a)端口的分隔。即便在同一个交换机上，处于不同VLAN的端口也是不能通信的。这样一个物理的交换机可以当作多个逻辑的交换机使用。b)网络的安全。不同VLAN不能直接通信，杜绝了广播信息的不安全性。c)灵活的管理。更改用户所属的网络不必换端口和连线，只更改软件配置就可以了4) IP地址规划以及VLAN划分网络实验室504为教室办公室，内有主机20台；网络实验室508内有主机50台；网络实验室511内有主机40台。电子楼数字媒体实验室有主机80台；软件工程实验室有主机160台；电子实验室有主机40台。三号楼共5层，每层均有25个信息点。网络中心核心交换机端口IP地址子网掩码说明F0/1
