I-PPPoE imele iphrothokholi yephoyinti-kuya-iphuzu ku-Ethernet. Iphrothokholi yomhubhe wenethiwekhi ehlanganisa iphrothokholi ye-point-to-point (PPP) kuhlaka lwe-Ethernet. Inika amandla abasingathi be-Ethernet ukuthi baxhume kusixhumi sokufinyelela esiqhelile ngomshini olula wokuhlanganisa ibhuloho.Ngokusebenzisa i-PPPoE, amadivaysi okufinyelela kude angakwazi ukulawula futhi aphendule umsebenzisi ngamunye wokufinyelela.Uma kuqhathaniswa nemodi yokufinyelela evamile, umthetho olandelwayo we-PPPoE unesilinganiso esiphezulu sokusebenza nenani. , isetshenziswa kabanzi ochungechungeni lwezinhlelo zokusebenza, okuhlanganisa ukwakhiwa kwenethiwekhi yeselula, njll., imodi yokufinyelela ye-broadband edumile yamanje i-ADSL isebenzisa i-PPPoE protocol.Ngokujwayelekile, ukwakheka kwe-PPPoE kuqukethe iklayenti le-PPPoE, iseva ye-PPPoE, i-host host kanye nemodemu ye-ADSL.
Nge-PPPoE, abasebenzisi bangadayela besuka kweyodwaumzila(iklayenti le-PPPoE) kwelinyeumzila(Iseva ye-PPPoE) nge-BRAS (Iseva Yokufinyelela Isilawuli kude se-Broadband), bese usungula uxhumano lwephoyinti nephoyinti futhi udlulise amaphakethe kulokhu kuxhumana. Ukuze usebenzise i-PPPoE, udinga igama lomsebenzisi nephasiwedi enikezwe i-ISP yakho ukuze usungule uxhumano. Kodwa-ke, kumanethiwekhi anamuhla, ukuhlanganisa imodemu kuxhumo, udinga kuphela ukusetha igama lomsebenzisi nephasiwedi kanye, futhi imodemu ixhuma ngokuzenzakalelayo kunethiwekhi ngokushesha nje lapho uyivula.
Njengoba i-BRAS (Iseva Yokufinyelela Isilawuli kude se-Broadband) inabasebenzisi abangenakubalwa ababelana ngoxhumano olungokwenyama olufanayo, oluthumela ithrafikhi ukuya nokubuya kumadivayisi okufinyelela akude e-broadband kunethiwekhi ye-ISP, iphrothokholi ye-PPPoE ingakwazi ukulandelela ithrafikhi yomsebenzisi nokuthi yimuphi umsebenzisi okufanele akhokhiswe.
Inqubo yokutholwa kweseshini ye-PPPoE kanye neseshini imi kanje:
Isigaba sokutholwa: Kulesi sigaba, umsingathi womsebenzisi uyasakaza ukuze athole zonke izigxivizo zokufinyelela ezixhunyiwe (noma amaswishi) futhi athole amakheli azo e-Ethernet MAC. Bese ukhetha umsingathi ofuna ukuxhuma kuye bese unquma inombolo kamazisi yeseshini ye-PPP ofuna ukuyisungula. Kunezinyathelo ezine esigabeni sokutholwa: umsingathi usakaza Iphakethe Lokuqala (i-PADI), ukufinyelela indawo yokugxilisa ingqondo, umsingathi ukhetha iphakethe le-PADO elifanele futhi ulungiselela ukuqala iseshini ye-PPP. Uma lesi sigaba sesiphelile, zombili izinhlangothi zokuxhumana ziyazi i-PPPoESESSION-ID nekheli le-Ethernet lontanga, futhi ndawonye zichaza ngokuhlukile iseshini ye-PPPoE.
Iseshini ye-PPP: Umsingathi womsebenzisi kanye nesixhumi sokufinyelela baqhuba izikhathi ze-PPP ngokusekelwe kumapharamitha wokuxhumeka kweseshini ye-PPP okuxoxiswene ngawo phakathi nesigaba sokutholwa. Uma iseshini ye-PPPoE iqala, idatha ye-PPP ingathunyelwa nganoma iyiphi enye indlela ye-PPP encapsulation. Wonke amafreyimu e-Ethernet ayi-unicast. Iseshini-ID ye-PPPoE SESSION ayikwazi ukushintshwa futhi kufanele kube inani elinikezwe phakathi nesigaba sokutholwa.
Lesi isingeniso se-PPPOE esilethwe kuwe ngabakwa-Shenzhen HDV Photoelectron Technology LTD. I-Shenzhen HDV Photoelectron Technology Ltd iyimishini yokuxhumana ekhethekile njengabakhiqizi abakhulu bemikhiqizo, futhi imikhiqizo ehlobene ne-PPPOE yile:oltwena, acwena, Ukuxhumanawena, i-fiber opticalwena, ikatiwena,gphowena,xponwena, njll., okokusebenza okungenhla kungasetshenziswa ezimeni ezahlukene, kanye nokuhambisanayoI-ONUimikhiqizo yochungechunge ingenziwa ngokwezifiso ngokwezidingo zabo. Inkampani yethu inganikeza ukwesekwa kobuchwepheshe nobuchwepheshe obuhle kakhulu. Ngibheke ngabomvu ukuvakasha kwakho.
