Gigabit ethernet protocol and its advantages 千兆以太網的協(xié)議體系結構及優(yōu)勢分析
A simple realization of the transmitters with industrial ethernet protocol 工業(yè)以太網變送器的一種簡易實現(xiàn)方法
Click " yes " to remove the dial - up connections created for the ppp over ethernet protocol " 按yes ,移除pppoverethernetprotocol的連線。
Then , about software design , this paper elaborates on the realization of the ethernet protocol and the interface drive of the ethernet 然后,在軟件設計方面,對以太網協(xié)議及以太網接口驅動的實現(xiàn)、以太網協(xié)議的實現(xiàn)進行了詳細論述。
This thesis begins with the introduction of some kernel protocols of tcp / ip stack and has realized the embedded termina with ethernet protocols 本論文主要介紹tcp ip協(xié)議簇的相關核心協(xié)議及以ethernet協(xié)議為代表的802 . 3協(xié)議在嵌入式dsp終端的實現(xiàn)。
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 第二章給出了以太網網絡協(xié)議,重點討論了以太網數(shù)據報的協(xié)議,尤其是以太幀和ip及udp數(shù)據報協(xié)議,并且給出了在catv網絡中傳送的ts流的報文協(xié)議。
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 但是傳統(tǒng)的現(xiàn)場總線在設備級上已廣泛使用并仍將長期存在,現(xiàn)實的情況是需要在不改變已有現(xiàn)場總線的基礎上實現(xiàn)與企業(yè)信息網絡的集成。
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 ) 施樂的帕洛阿爾托研究中心研制了個人電腦的獨特部件,包括鼠標、圖形用戶界面和使計算機互聯(lián)的以太網協(xié)議(盡管它因未能將這些飛躍商業(yè)化而遭批評) 。
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結構的arm處理器與armlinux嵌入式操作系統(tǒng)相結合,并利用ethernet / ip工業(yè)以太網協(xié)議構造嵌入式網關,實現(xiàn)設備的現(xiàn)場總線與企業(yè)信息網絡無縫鏈接,并保證了devicenet和controlnet兩種網絡的互操作性,構建一個可跨地域共享、便于實現(xiàn)高層次集中管理、監(jiān)控和決策的新型嵌入式實時在線監(jiān)控網絡。
