Inkcazo yeprotocol yileyibhile yonxibelelwano yekholamu, amacala amabini onxibelelwano kufuneka aqhube ngokudibeneyo ukuhanjiswa kwedatha eqhelekileyo ngokwalo mgangatho. Kunxibelelwano lwekhompyuter, iprothokholi yonxibelelwano isetyenziselwa ukuqonda ukuleyibhile phakathi kwekhompyuter kunye noqhagamshelo lwenethiwekhi, ukuba akukho protocol yonxibelelwano olumanyeneyo, ukuhanjiswa kolwazi phakathi kweekhompyuter akunakuchongwa, iprotocol yonxibelelwano yimithetho yonxibelelwano ekuvunyelwene ngayo. macala amabini ngaphambili. Inokuqondwa ngokulula njengolwimi oluqhelekileyo olusetyenziswa ziikhompyuter ukuthetha omnye komnye
Isitaki seprothokholi sibhekisa kuhlobo oluthile lophumezo lweprotokoli, sithetha ngokubanzi ngumsebenzi wethala leencwadi ophunyezwe ngekhowudi, ukuze kube lula ukufowunelwa komphuhlisi. Isitaki seprothokholi sisimbuku seprothokholi kumaleko ngamnye wothungelwano, kwaye umfanekiso wayo ubonisa inkqubo yokudlulisa iifayile kuthungelwano. Ukusuka kwiprotocol ephezulu ukuya kwiprotocol esezantsi, kwaye ukusuka kwiprotocol esezantsi ukuya kwiprotocol ephezulu.
Abaqulunqi benethiwekhi basebenzisa i-hierarchical network architecture, inkqubo yokunxibelelana phakathi kwemikhosi emibini, kuquka izixhobo zokutshintsha, iprotocol isebenza njenge-stack, ngoko ibizwa ngokuba yi-protocol stack.
Umamkeli a: Umaleko wesicelo- -> Umaleko wothumelo- -> Umaleko wothungelwano- -> Umaleko woNxibelelwano lweDatha- -> Umaleko obonakalayo, umamkeli ohambelanayo b: Umaleko obonakalayo- -> Umaleko woNxibelelwano lweDatha- -> Umaleko wothungelwano- -> Umaleko wothumelo- -> Umaleko wosetyenziso
Oku kungasentla yingcaciso emfutshane yomahluko phakathi kweprotocol kunye neprotocol stack eziswe yiShenzhen HDV Phoelectron Technology Co., LTD. Izixhobo zenethiwekhi ezifanelekileyo ze-Shenzhen HDV Phoelectron Technology Co., LTD.. inesoftware ehambelana nemveliso yethu, ezi mveliso zenethiwekhiI-ONUuthotho, uthotho lweemodyuli zokukhanya,OLTseries, transceiver series. Wamkelekile kwimfuno yabasebenzi ukuze ufumane ukuqonda okuneenkcukacha kwimveliso !
I-VLAN ibhekisa kuthungelwano lwendawo yengingqi, liqela lezixhobo ezinengqondo kunye nabasebenzisi, unxibelelwano phakathi kweli qela lezixhobo kunye nabasebenzisi luyafana kwicandelo lothungelwano olufanayo, lunokuba neendawo ezahlukeneyo, uthungelwano olwahlukeneyo, abasebenzisi abohlukeneyo kunye ukwenza i-virtual yenyani. ubume benethiwekhi, njengokusetyenziswa kwe-LAN yasekuhlaleni njengento elula, eguquguqukayo, esebenzayo. I-VLAN inokunciphisa iindleko zolawulo lokuhamba okanye ukutshintsha indawo yeendawo zokusebenzela, ngakumbi kwiinkampani ezithile ezinokutshintsha rhoqo kwiimeko zoshishino, le nxalenye yeendleko zolawulo ziyancipha kakhulu.
Ukuzihlukanisa kweVlan ngokwenene kusekelwe kwindima yeteknoloji yeVlan, ngokusebenzisa isahlulo seVlan samachweba ahlukeneyo, izixhobo ze-terminals, abasebenzisi ukuphumeza ukuhlukaniswa okupheleleyo kwedatha yezoshishino. Ukongeza, ukwahlukaniswa kweVlan kunokusekwa kwizibuko letshintshaUkwahlulahlula kweVlan kokwahlulahlula uthungelwano, nako kunokusekwa kwi-IP Vlan isahlulelo sokwahlula kuthungelwano lwe-Ethernettshintshaphantsi VLAN technology, ungakha LAN ezininzi, ebomini bokwenyani, ufuna ukwakha LAN eyahlukileyo kwizibuko ngalinye, Umzekelo, isebe R&D, isebe loshishino, isebe ukusebenza, njl, yenkampani enye.
Enkosi ngokuphonononga ukuqaliswa komsebenzi wokuhlukaniswa weVLAN we-Ethernettshintshaeziswa nguShenzhen Haidwiwei Optoelectronic Technology Co., LTD., Yethutshintshauthotho lwemveliso, ikwagubungela inani leenkcazo zetshintsha, njenge: zonke izibuko zamehlotshintsha, 8 izibukotshintsha, 100 MEGABIttshintsha, ulawulo lwenethiwekhitshintshanjalo njalo, wamkelekile ukutyelela.
I-16, i-Broadband kunye ne-Dial-up
Sasidla ngokusebenzisa i-ADSL Broadband. I-ADSL: I-Asymmetric Digital Subscriber Line.
Ibroadband isetyenziswa ngokudibanisa intambo yefowuni esuka kwisiphathi sakho sebroadband ukuya kwimodem yakho yangaphakathi (eyaziwa ngokuba yikati) emva koko usebenzisa intambo ukuqhagamshela kwezinye izixhobo eziqhagamshelwe kwi-Intanethi.
Emva kweminyaka yophuhliso, i-ADSL idlule kwizizukulwana ezithathu, ukusuka kwi-ADSL yasekuqaleni ukuya kwi-ADSL2 ephuculweyo kamva kwaye ngoku i-ADSL2 +, isantya sokukhuphela sinokufikelela kwi-24M. I-ADSL isebenzisa i-multiplexing ye-frequency division ukuze ibone ukuba isignali yefowuni, i-uplink kunye ne-downlink signals ayichaphazeli enye kwenye.
Namhlanje, ukusetyenziswa ngakumbi kwefayibha endlwini (FTTH), emva kwayo yonke loo nto, isantya sokuhambisa ukukhanya kunesantya sokuhambisa umbane, sisebenza ngakumbi. I-FTTH isebenza ngokutsala i-fiber optic ukusuka kumthuthi ukuya kwikhaya lakho kwaye idibanise nemodem ekhanyayo (eyaziwa ngokuba yikati ekhanyayo). Emva koko sebenzisa intambo ye-Intanethi esuka kwikati ekhanyayo ukukhokelela kwi-Intanethi.
I-intanethi ye-Dial-up ngokuqhelekileyo ibhekisela kwi-PPPoe yokudayela, eyindlela yokufikelela kwi-Intanethi, zombini i-ADSL broadband dial-up (ukuhanjiswa kwefowuni yomnxeba) kunye ne-fiber optic dial-up (i-fiber optic transmission). I-PPPoe ibhekisela kwiProtocol yePoint-to-Point Over Ethernet, oku kuthetha ukuba kukho iimpawu ezimbini zomncedisi kunye nomxhasi kwi-point-to-point protocol PPPoe kwi-Intanethi. Umsebenzisi ufumana kwaye athumele ulwazi kumxhasi wabasebenzisi abaqhelekileyo njengeseva, eyi-topology enye ukuya kwabaninzi. Ukuze ukwahlula isazisi kunye nesiqinisekiso somxhasi ngamnye, umsebenzisi ngamnye kufuneka abhalise i-akhawunti kunye negama lokugqitha kumsebenzisi, aze afake iakhawunti kunye negama lokugqitha kwikhompyuter yakhe esebenzisa isoftware ethile ukuyithumela kumncedisi womqhubi. Ukuba i-akhawunti isemthethweni, unokungena kwi-Intanethi ngokuqhelekileyo. Kakade ke, ngamanye amaxesha siya kufumanisa ukuba sinokungena kwi-Intanethi ngaphandle kokufaka igama eliyimfihlo kwikhompyutha. Kungenxa yokuba igama lokugqithisa leakhawunti licwangciswe kwangaphambili kwikati, ngoko akufuneki ukuba siyifake ngesandla.
Oku kungasentla yinkcazo emfutshane yebroadband kunye nokucofa-up eziswa yiShenzhen HDV Phoelectron Technology Co., LTD. Izixhobo zenethiwekhi ezifanelekileyo ze-Shenzhen HDV Phoelectron Technology Co., Ltd. inesoftware ehambelana neemveliso zethu, ezi mveliso zenethiwekhiI-ONUuthotho, uthotho lweemodyuli zokukhanya,OLTseries, transceiver series.
