Gigabit ethernet protocol and its advantages 千兆以太网的协议体系结构及优势分析
A simple realization of the transmitters with industrial ethernet protocol 工业以太网变送器的一种简易实现方法
Click " yes " to remove the dial - up connections created for the ppp over ethernet protocol " 按yes ,移除pppoverethernetprotocol的连线。
Then , about software design , this paper elaborates on the realization of the ethernet protocol and the interface drive of the ethernet 然后,在软件设计方面,对以太网协议及以太网接口驱动的实现、以太网协议的实现进行了详细论述。
This thesis begins with the introduction of some kernel protocols of tcp / ip stack and has realized the embedded termina with ethernet protocols 本论文主要介绍tcp ip协议簇的相关核心协议及以ethernet协议为代表的802 . 3协议在嵌入式dsp终端的实现。
Chapter two provides ethernet protocols , issues on ethernet packets , especially on ethernet frame , ip and udp packets . also it provides the protocols of ts packets which are transmitted in catv network 第二章给出了以太网网络协议,重点讨论了以太网数据报的协议,尤其是以太帧和ip及udp数据报协议,并且给出了在catv网络中传送的ts流的报文协议。
On the other hand , it is difficult to connect fieldbus to office network which mostly built in ethernet protocol . industrial ethernet will be the main orientation of control system network and can easily realize amalgamation of devices network with office network 但是传统的现场总线在设备级上已广泛使用并仍将长期存在,现实的情况是需要在不改变已有现场总线的基础上实现与企业信息网络的集成。
And xerox ' s palo alto research centre ( parc ) devised the personal computer ' s distinctive elements , including the mouse , the graphical user interface and the ethernet protocol for computer networking ( although it was criticised for failing to commercialise such leaps forward ) 施乐的帕洛阿尔托研究中心研制了个人电脑的独特部件,包括鼠标、图形用户界面和使计算机互联的以太网协议(尽管它因未能将这些飞跃商业化而遭批评) 。
But traditional fieldbus has been widly used in factory field and will act an important part for a long time , so it is necessary that to realize fieldbus connect to office network , make it has the capability of inter - connection and inter - operation , and keep it ’ s architecture unchanged . the paper discusses a method to slove the problem . that is making use of ethernet / ip protocol which is one of industrial ethernet protocols , to design an embedded fieldbus gateway . the gateway mainly consists of s3c2410 , a 32bit high performance microprocessor based on arm core , to realize interconnection devicenet network , controlnet to ethernet 本文提出利用高性能、低功耗32位risc结构的arm处理器与armlinux嵌入式操作系统相结合,并利用ethernet / ip工业以太网协议构造嵌入式网关,实现设备的现场总线与企业信息网络无缝链接,并保证了devicenet和controlnet两种网络的互操作性,构建一个可跨地域共享、便于实现高层次集中管理、监控和决策的新型嵌入式实时在线监控网络。
