PPPoE sawv cev rau qhov taw tes-to-point raws tu qauv ntawm Ethernet. Nws yog lub network tunnel raws tu qauv uas encapsulates point-to-point raws tu qauv (PPP) nyob rau hauv lub Ethernet moj khaum. Nws ua rau Ethernet hosts txuas mus rau cov chaw taws teeb nkag mus rau hauv cov chaw taws teeb ntawm cov khoom siv txuas yooj yim.Siv PPPoE, cov chaw taws teeb nkag tuaj yeem tswj hwm thiab suav nyiaj rau txhua tus neeg siv.Piv nrog rau hom kev siv ib txwm siv, PPPoE raws tu qauv muaj qhov ua tau zoo dua-rau-tus nqi piv. , nws yog dav siv nyob rau hauv ib tug series ntawm daim ntaub ntawv, nrog rau kev tsim kho ntawm tes networking, thiab lwm yam., tam sim no nrov broadband nkag hom ADSL siv PPPoE raws tu qauv. Feem ntau, PPPoE architecture muaj PPPoE tus thov kev pab, PPPoE server, host thiab ADSL modem.
Nrog PPPoE, cov neeg siv tuaj yeem hu los ntawm ib qhorouter(PPPoE tus thov kev pab) rau lwm tusrouter(PPPoE neeg rau zaub mov) los ntawm BRAS (Broadband Remote Access Server), thiab tom qab ntawd tsim kom muaj kev sib txuas ntawm taw tes rau-taw tes thiab hloov pob ntawv hla qhov kev sib txuas no. Txhawm rau siv PPPoE, koj xav tau tus neeg siv lub npe thiab lo lus zais muab los ntawm koj ISP los tsim kev sib txuas. Txawm li cas los xij, nyob rau niaj hnub no, txhawm rau muab lub modem rau hauv kev sib txuas, koj tsuas yog yuav tsum teeb tsa tus username thiab password ib zaug, thiab modem cia li txuas mus rau lub network sai li sai tau thaum koj qhib nws.
Txij li thaum BRAS (Broadband Remote Access Server) muaj suav tsis txheeb cov neeg siv sib koom tib lub cev kev sib txuas, uas xa cov tsheb mus rau thiab los ntawm cov chaw taws teeb nkag mus rau hauv ISP network, PPPoE raws tu qauv tuaj yeem taug qab cov neeg siv tsheb thiab tus neeg siv yuav tsum tau them nqi.
Cov txheej txheem ntawm PPPoE qhov kev tshawb pom thiab kev sib tham yog raws li hauv qab no:
Discovery theem: Hauv theem no, tus neeg siv lub tswv yim tshaj tawm kom pom tag nrho cov kev sib txuas nkag mus rau concentrators (los yog keyboards) thiab tau txais lawv qhov chaw nyob Ethernet MAC. Tom qab ntawd xaiv tus tswv tsev uas koj xav txuas mus rau thiab txiav txim siab PPP kev sib ntsib tus lej koj xav tsim. Muaj plaub kauj ruam nyob rau hauv lub sij hawm nrhiav pom: tus tswv tsev tshaj tawm xov xwm Initiating Packet (PADI), nkag mus rau lub concentrator, tus tswv tsev xaiv ib lub pob khoom tsim nyog PADO thiab npaj pib lub rooj sib tham PPP. Thaum lub sijhawm no tiav, ob sab ntawm kev sib txuas lus paub PPPoESESSION-ID thiab Ethernet chaw nyob ntawm cov phooj ywg, thiab ua ke lawv tshwj xeeb txhais lub PPPoE kev sib kho.
PPP kev sib kho: Tus neeg siv lub tswv yim thiab tus neeg siv nkag mus tau ua PPP ntu raws li PPP kev sib tham sib txuas tsis sib tham thaum lub sijhawm tshawb pom. Thaum pib qhov kev sib tham PPPoE, PPP cov ntaub ntawv tuaj yeem xa mus rau lwm daim ntawv PPP encapsulation. Txhua Ethernet thav duab yog unicast. Kev sib kho-ID ntawm PPPoE SESSION tsis tuaj yeem hloov pauv thiab yuav tsum yog tus nqi muab rau lub sijhawm tshawb pom.
Nov yog kev qhia txog PPPOE coj los rau koj los ntawm Shenzhen HDV Photoelectron Technology LTD. Shenzhen HDV Photoelectron Technology Ltd yog cov khoom siv sib txuas lus tshwj xeeb raws li cov khoom lag luam tseem ceeb, thiab PPPOE cov khoom muaj feem xyuam yog:olt uaonu, ac ibonu, Kev sib txuas lusonu, optical fiber ntauonu,cavonu,gpon uaonu, xpononu, thiab lwm yam, cov khoom siv saum toj no tuaj yeem siv rau cov xwm txheej sib txawv, thiab sib xwsONUseries khoom tuaj yeem kho raws li lawv tus kheej xav tau. Peb lub tuam txhab tuaj yeem muab kev txhawb nqa kev tshaj lij thiab zoo tshaj plaws. tos ntsoov rau koj mus ntsib.
