Incazelo yephrothokholi ilebula yokuxhumana yekholomu, izinhlangothi ezimbili zokuxhumana zidinga ukwenza ngokuhlanganyela ukudluliswa kwedatha okujwayelekile ngokwaleli zinga. Ekuxhumaneni kwekhompyutha, iphrothokholi yokuxhumana isetshenziselwa ukubona ukulebula phakathi kwekhompyutha noxhumo lwenethiwekhi, uma ingekho iphrothokholi yokuxhumana ebumbene, ukudluliswa kolwazi phakathi kwamakhompyutha akukwazi ukuhlonzwa, iphrothokholi yokuxhumana iyimithetho yokuxhumana okuvunyelwene ngayo izinhlangothi ezimbili kusengaphambili. Kungaqondwa kalula njengolimi olujwayelekile olusetshenziswa amakhompiyutha ukukhuluma ngomunye nomunye
Isitaki sephrothokholi sisho uhlobo oluthile lokusetshenziswa lwephrothokholi, esivame ukukhuluma ngayo wumsebenzi womtapo wezincwadi osetshenziswa ngekhodi, ukuze kube lula ukubizwa kukanjiniyela. Isitaki sephrothokholi siyisamba samaphrothokholi kusendlalelo ngasinye senethiwekhi, futhi isithombe saso sibonisa inqubo yokudlulisa ifayela kunethiwekhi. Kusukela kuphrothokholi ephezulu kuya kweyomthetho olandelwayo ephansi, futhi kusukela kumthethonqubo ophansi kuya kwephezulu.
Abaqambi benethiwekhi basebenzisa i-hierarchical network architecture, inqubo yokuxhumana phakathi kwama-host amabili, kuhlanganise nokushintsha imishini, iphrothokholi isebenza njengesitaki, ngakho-ke ibizwa ngokuthi i-protocol stack.
Setha a: Isendlalelo sohlelo lokusebenza- -> Isendlalelo sokudlulisa- -> Isendlalelo senethiwekhi- -> Isendlalelo sesixhumanisi sedatha- -> Isendlalelo esibonakalayo, isikhungo esihambelanayo b: Isendlalelo esibonakalayo- -> Isendlalelo sesixhumanisi sedatha- -> Isendlalelo senethiwekhi- -> Isendlalelo sokudlulisa- -> Isendlalelo sohlelo lokusebenza
Okungenhla kuyincazelo emfushane yomehluko phakathi kwephrothokholi nesitaki sephrothokholi elethwa yi-Shenzhen HDV Phoelectron Technology Co., LTD. Impahla yenethiwekhi efanele ye-Shenzhen HDV Phoelectron Technology Co., LTD.. inesofthiwe ehambisana nemikhiqizo yethu, le mikhiqizo yenethiwekhiI-ONUuchungechunge, uchungechunge lwamamojula optical,OLTuchungechunge, uchungechunge lwe-transceiver. Siyakwamukela kubasebenzi abafuna ukuqonda okuningiliziwe komkhiqizo!
I-VLAN ibhekisela kunethiwekhi yendawo yendawo, iyiqembu lemishini enengqondo nabasebenzisi, ukuxhumana phakathi kwaleli qembu lemishini nabasebenzisi kuyafana engxenyeni yenethiwekhi efanayo, kungaba izindawo ezihlukene, amanethiwekhi ahlukene, abasebenzisi abahlukene ndawonye ukwakha i-virtual segment. imvelo yenethiwekhi, njengokusetshenziswa kwe-LAN yendawo njengento elula, eguquguqukayo, ephumelelayo. I-VLAN inganciphisa izindleko zokuphatha zokuhamba noma ukushintsha indawo yezindawo zokusebenza, ikakhulukazi kwezinye izinkampani ezinezinguquko ezivamile ezimweni zebhizinisi, le ngxenye yezindleko zokuphatha iyancipha kakhulu.
Ukuhlukaniswa kwe-Vlan empeleni kusekelwe endimeni yobuchwepheshe be-Vlan, ngokusebenzisa isigaba se-Vlan samachweba ahlukene, amatheminali wemishini, abasebenzisi ukuze bathole ukuhlukaniswa okuphelele kwedatha yebhizinisi. Ngaphezu kwalokho, ukuhlukaniswa kwe-Vlan kungase kusekelwe echwebeni le-shintshaI-Vlan partition for networking isolation, nayo ingasuselwa ku-IP Vlan partition ye-network isolation Ethernetshintshangaphansi kobuchwepheshe be-VLAN, ungakha i-LAN eminingi, empilweni yangempela, ufuna ukwakha i-LAN ehlukile yechweba ngalinye, Isibonelo, umnyango we-R&D, umnyango webhizinisi, umnyango wokusebenza, njll., wenkampani efanayo.
Siyabonga ngokubuyekeza ukwethulwa komsebenzi wokuhlukanisa we-VLAN we-Ethernetshintshailethwe yi-Shenzhen Haidwiwei Optoelectronic Technology Co., LTD., Yethushintshauchungechunge lomkhiqizo, futhi luhlanganisa imininingwane eminingi yeshintsha, njengokuthi: yonke imbobo yokubonashintsha,8 portshintsha, 100 MEGABItshintsha, ukuphathwa kwenethiwekhishintshanokunye, wamukelekile ukuvakasha.
16, I-Broadband ne-Dial-up
Sasivame ukusebenzisa i-Broadband ye-ADSL. I-ADSL: I-Asymmetric Digital Subscriber Line.
I-Broadband isetshenziswa ngokuxhuma ulayini wefoni osuka kusiphathi sakho se-broadband ukuya kumodemu yakho yasendlini (eyaziwa kakhulu ngokuthi ikati) bese kusetshenziswa ikhebula ukuxhuma kwamanye amadivayisi axhumeke ku-inthanethi.
Ngemva kweminyaka yokuthuthuka, i-ADSL isidlule ezizukulwaneni ezintathu, kusukela ku-ADSL yasekuqaleni kuya ku-ADSL2 ethuthukisiwe kamuva futhi manje i-ADSL2+, isivinini sokulanda manje singafinyelela ku-24M. I-ADSL isebenzisa i-frequency division multiplexing ukuze ibone ukuthi isignali yocingo, i-uplink ne-downlink amasignali ayithinti enye kwenye.
Namuhla, ukusetshenziswa okuningi kwe-fiber endlini (FTTH), ngemva kwakho konke, isivinini sokudlulisa ukukhanya kunesivinini sokudlulisa ugesi, sisebenza kahle kakhulu. I-FTTH isebenza ngokudonsa i-fiber optic ukusuka kusiphathi ukuya ekhaya lakho bese iyixhuma kumodemu ekhanyayo (eyaziwa kakhulu ngokuthi ikati elikhanyayo). Bese usebenzisa ikhebula le-inthanethi elisuka ekati elikhanyayo ukuholela ku-inthanethi.
I-inthanethi yokudayela ngokuvamile isho ukudayela kwe-PPPoe, okuyindlela yokufinyelela ku-inthanethi, kokubili i-ADSL broadband dial-up (ukuthumela ngocingo locingo) kanye ne-fiber optic dial-up (i-fiber optic transmission). I-PPPoe ibhekisela ku-Point-to-Point Protocol Over Ethernet, okusho ukuthi kukhona ubunikazi obubili beseva neklayenti kuphrothokholi yephoyinti-kuya-iphuzu i-PPPoe ku-inthanethi. Umsebenzisi uthola futhi athumele ulwazi kuklayenti labasebenzisi abajwayelekile njengeseva, okuyi-topology eyodwa kuya kwabaningi. Ukuze kuhlukanise ubunikazi nokufaneleka kweklayenti ngalinye, umsebenzisi ngamunye udinga ukubhalisa i-akhawunti nephasiwedi ku-opharetha, bese efaka i-akhawunti nephasiwedi kukhompyutha yakhe esebenzisa isofthiwe ethile ukuyithumela kuseva yomsebenzisi. Uma i-akhawunti isemthethweni, angangena kuyi-Internet ngendlela evamile. Yebo, ngezinye izikhathi sizothola ukuthi singakwazi ukungena ku-inthanethi ngaphandle kokufaka iphasiwedi ye-akhawunti kukhompuyutha. Lokho kungenxa yokuthi iphasiwedi ye-akhawunti isethwe kusengaphambili ekatini, ngakho-ke akudingekile ukuthi siyifake mathupha.
Okungenhla kuyincazelo emfushane ye-broadband kanye nokudayela okulethwe yi-Shenzhen HDV Phoelectron Technology Co., LTD. Impahla yenethiwekhi efanele ye-Shenzhen HDV Phoelectron Technology Co., Ltd. inesofthiwe ehambisana nemikhiqizo yethu, le mikhiqizo yenethiwekhiI-ONUuchungechunge, uchungechunge lwamamojula optical,OLTuchungechunge, uchungechunge lwe-transceiver. Siyakwamukela ukucela izisebenzi ukuze uthole ukuqonda okuningiliziwe komkhiqizo
