IEEE Standard for Ethernet Amendment 3: Physical Layer Specifications and Management Parameters for 40 Gb/s and 100 Gb/s Operation over Fiber Optic Cables

IEEE802.11系列协议OPNET建模与性能测试，罗维，姜秀柱，本文讨论了IEEE802.11系列协议的建模与性能问题。基于对IEEE802.11a/b/g三个不同版本的协议和目前功能最强大的网络仿真工具OPNET软件的研究

IEEE 802.3以太网帧封装 一）设计内容 编写程序实现IEEE 802.3以太网帧封装。 二） 设计要求 1）基本要求： A)要求画出界面，以太网帧的数据部分、源MAC地址和目的MAC地址均从界面输入； B)计算后的校验和字段和封装后的结果可以从界面上输出； C) 生成多项式G（X）=X8+X2+X+1； D)使用的操作系统、语言和编译环境不限，但必须在报告中注明。 2）扩展要求： A) 能够实现CRC计算过程的可视化； B) 能够从界面上控制程序的运行。 3）相关理论知识 按802.3标准的帧结构如下表所示（802.3标准的Ethernet帧结构由7部分组成） 802.3标准的帧结构 前导码 帧前定界符 目的地址 源地址 长度字段 数据字段 校验字段 7B 1B (6B) (6B) (2B) (长度可变) (4B) 其中，帧数据字段的最小长度为46B。如果帧的LLC数据少于46B，则应将数据字段填充至46B。填充字符是任意的，不计入长度字段值中。 在校验字段中，使用的是CRC校验。校验的范围包括目的地址字段、源地址字段、长度字段、LLC数据字段。
