一、知识回顾
1、OSI七层参考模型
物理层——定义电气电压接口规范光学特性 数据链路层
MAC媒介访问控制层LLC逻辑链路层为上层提供FCS校验
网络层——通过IP地址进行逻辑寻址代表设备路由器。 物理层数据链路层以及网络层能不能全网可达可以全网可达。 传输层——通过端口号区分不同的服务数据分段确认重传排序流控只针对于TCP。
TCP面向连接的可靠传输协议 面向连接 三次握手以及四次挥手主要体现 可靠 确认重传排序以及流控。 常见的四层协议 TCPUDP 常见的三层协议 IPICMPARPUDP非面向连接的不可靠传输协议
会话层——建立维持终止会话进程。 表示层——编码解码加密解密 应用层——实现人机交互的界面 数据封装以及解封装 以太网一类帧二类帧封装——IP——TCP/UDP——data数据包——FCS校验逻辑链路层提供 数据分段的标准MYU最大传输单元1500字节MSS最大段长度1480。原因是报头长度为20字节 TCP-IP协议栈与OSI模型对比
相同点 1、都是模型化层次 2、下层对上层提供服务支持 3、每层协议彼此相互独立不同点 1、TCP-IP协议栈先有协议后有模型只是使用于TCP-IP网络。 2、OSI七层参考模型先有模型后有协议。 3、层数不同 滑动窗口就是流控什么是滑动窗口其实是吞吐量的问题。 2、重要的几个协议报头格式
IPV4数据包结构 IPV4数据包格式
版本号 这4比特规定了数据报的IP协议版本。通过查看版本号路由器能够确定如何解释IP数据报的剩余部分。不同的IP版本使用不同的数据报格式。首部长度 因为IPV4数据报可包含一些可变数量的选项这些选项包括在IPV4数据报首部中故需要用这4个比特来确定IP数据报中载荷例如在这个数据报中被封装的运输层报文段实际开始的地方。大多数IP数据报不包含选项所以一般的IP数据报具有20字节的首部。服务类型 服务类型TOS比特包含在IPV4首部中以便使不同类型的IP数据报能相互与别开来例如将实时数据报如用于IP电话应用与非实时流量如FTP区分开也许是有用的。提供特定等级的服务是一个由网络管理员为路由器确定和配置的策略问题。数据报长度
二、静态实验
1、实验拓扑图 2、实验要求
1.全网可达2.拓扑中所需地址全部基于192.168.0.0/24划分所得3.静态路由不许使用其他动态4.R8环回需要汇总
3、实验思路
拓扑中所需地址基于192.168.0.0/24进行划分这里我们首先数图中需要多少个网段
骨干链路——6个网段R1的环回上——1个网段两个vlan——两个网段
所以我们首先进行划分网段
192.168.0.0/24需要划分9个网段——也就向后借位借4位
128-64-32-16-8-4-2-1
这里我们可以看到第四位为16
那么9个网段分别为
192.168.0.0/28——R1环回
192.168.0.16/28——骨干链路网段
192.168.0.32/28
192.168.0.48/28
192.168.0.64/28
192.168.0.80/28
192.168.0.96/28
192.168.0.112/28——两个vlan
192.168。0.128/28
剩下的作为保留网段而这里我们也需要对R1的环回进行划分由实验要求的拓扑图可知我们需要给它划分3个环回网段
192.168.0.0/28划分为3个网段我们需要向后借2位
也就成了
192.168.0.0/30
192.168.0.64/30
192.168.0.128/30
同时剩下的作为保留网段拓扑图如下
