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。

IEEE Std 802.3-2012 Section One—Includes Clause 1 through Clause 20 and Annex A through Annex H and Annex 4A. Section One includes the specifications for 10 Mb/s operation and the MAC, frame formats and service interfaces used for all speeds of operation. Section Two—Includes Clause 21 through Clause 33 and Annex 22A through Annex 33E. Section Two includes management attributes for multiple protocols and speed of operation as well as specifications for providing power over twisted-pair cabling for multiple operational speeds. It also includes general information on 100 Mb/s operation as well as most of the 100 Mb/s Physical Layer specifications. Section Three—Includes Clause 34 through Clause 43 and Annex 36A through Annex 43C. Section Three includes general information on 1000 Mb/s operation as well as most of the 1000 Mb/s Physical Layer specifications. Section Four—Includes Clause 44 through Clause 55 and Annex 44A through Annex 55B. Section Four includes general information on 10 Gb/s operation as well as most of the 10 Gb/s Physical Layer specifications. Section Five—Includes Clause 56 through Clause 77 and Annex 57A through Annex 76A. Clause 56 through Clause 67 and Clause 75 through Clause 77, as well as associated annexes, specify subscriber access and other Physical Layers and sublayers for operation from 512 kb/s to10 Gb/s, and defines services and protocol elements that enable the exchange of IEEE Std 802.3 format frames between stations in a subscriber access network. Clause 68 specifies a 10 Gb/s Physical Layer specification. Clause 69 through Clause 74 and associated annexes specify Ethernet operation over electrical backplanes at speeds of 1000 Mb/s and 10 Gb/s. Section Six—Includes Clause 78 through Clause 90and Annex 83A through Annex 86A. Clause 78 specifies Energy-Efficient Ethernet. Clause 79 specifies IEEE 802.3 Organizationally Specific Link Layer Discovery Protocol (LLDP) type, length, and value (TLV) information elements. Clause 80 through Clause 89 and associated annexes includes general information on 40 Gb/s and 100 Gb/s operation as well the 40 Gb/s and 100 Gb/s PhysicalLayer specifications. Clause90 specifies Ethernet support for time synchronization protocols.
