Amathuba nezinselelo zamanethiwekhi e-POL campus
Eminyakeni yamuva nje, ekwakhiweni kwamanethiwekhi e-campus, izixazululo ze-POL (Passive Optical LAN) ziye zanda zaba yisinqumo sokuqala samakhasimende, futhi ukwakhiwa kwamanethiwekhi e-optical campus kuye kwaba ukuqonda okuhlangene kwemboni. Uma kuqhathaniswa ne-Ethernet LAN yendabuko, i-POL inezici zokuvikeleka okuphezulu, ukusetshenziswa kwamandla okuphansi, ibanga elide, impilo ende, inethiwekhi eyenziwe lula kanye nokusebenza okuphakathi nendawo nokugcinwa. Ngokusekelwe ekutshalweni kwezimali kwesikhathi eside kanye nokuqoqwa kobuchwepheshe ekuthuthukisweni kwenethiwekhi yokufinyelela ye-PON emakethe yasekhaya, opharetha bakhuthaza ngenkuthalo ukwakhiwa kwenethiwekhi ye-POL epaki. Isibonelo, inethiwekhi yangasese ye-China Telecom YOKUQALA yemfundo isebenzisa ubuchwepheshe be-PON, futhi imboni yamahhotela isivele imboze amanethiwekhi e-PON ngezinga elikhulu. Inkambu ye-inthanethi yezimboni iphakamise umqondo we-PON yezimboni futhi yenze ukulinganisa.
Uma kuqhathaniswa namanethiwekhi okufinyelela e-PON endabuko ekhaya lonke, i-POL isebenzisa ubuchwepheshe obufanayo be-PON, kodwa ibhekene nendawo yokuxhumana eyinkimbinkimbi kanye nezidingo eziphakeme zamakhasimende. Inethiwekhi yekhampasi ye-POL inalezi zimpawu nezidingo eziyisisekelo ezilandelayo.
1) Kunezinhlobo eziningi zezinsizakalo, ezifaka amasevisi e-inthanethi yehhovisi, izinsizakalo zokuqapha ukuphepha, amasevisi ezwi le-intranethi, izinsiza zokutholwa kwedatha yezimboni, kanye namasevisi enethiwekhi angasese ezemfundo.
2) Amatheminali okufinyelela ahlukahlukene, okuhlanganisa asanda kufakwaAma-ONU, i-Ethernet yendabukoamaswishi, ama-APs angenantambo, amatheminali okutholwa kwedatha yezimboni, njll.
3) Izimfuneko zokuphepha eziphezulu nokuthembeka. Akumele nje imelane nokuhlaselwa kwenethiwekhi yangaphandle, kodwa futhi ivimbele ukufinyelela komsebenzisi okungekho emthethweni kanye nokufinyelela ekugcineni okungagunyaziwe. Ukuthembeka okuphezulu kudinga ukuvikelwa kokungadingeki komsebenzi ezingeni lenethiwekhi kanye nezisetshenziswa, ikakhulukazi emkhakheni wezimboni, odinga ukutholakala kwesistimu okungu-99.999%.
4) Izidingo zokuphatha nokusebenza nokugcinwa zilula futhi ziyashesha. Inethiwekhi yekhampasi iyimakethe ehlukile. Umzimba osebenzayo oyinhloko kungaba ukunakekelwa komsebenzisi, ama-ejenti, izakhiwo zepaki, noma amayunithi ekhasimende. Ukuze kuncishiswe izindleko zokusebenza nezokulungisa, ukuthunyelwa kwebhizinisi kufanele kube lula ngangokunokwenzeka futhi nokuphathwa kokusebenza nokulungiswa kufanele kube lula ngangokunokwenzeka.
5) Ukufinyelela okuhlanganisiwe kwezintambo nokungenantambo. Ukufakwa kwe-Wi-Fi yekhampasi kudinga ukuthunyelwa kwenombolo enkulu yamadivayisi angenantambo we-AP, okuhlanganisa nokuphakelwa kwamanethiwekhi ayimfihlo e-5G. I-POL kufanele ibhekane nezinselele zokulawula ezibangelwa yilawa madivayisi enethiwekhi ahlukahlukene.
6) Ukusetshenziswa kobuchwepheshe bekhompiyutha onqenqemeni. Uhlelo lokusebenza olujwayelekile lwekhompuyutha enqenqemeni ukubonwa kwesithombe sokugadwa kwevidiyo. Ngokusekelwe kwizidingo zokuphepha kwedatha, izinsiza zekhompuyutha ezisemaphethelweni zidinga ukufakwa ngaphakathi kwekhampasi.
7) Izidingo zokubambezeleka eziphansi. Isistimu yokulawula yezimboni enembayo ephezulu idinga ukubambezeleka kwenethiwekhi yokulawula kube ngaphansi kwe-millisecond engu-1. Ubuchwepheshe be-PON bendabuko abukwazi ukuhlangabezana ngokugcwele nezimfuneko.
Ngaphezu kwalokho, ezimweni ezithile, ukuphathwa kwabaqashi abaningi emapaki ezimboni ezinkulu, ukuhlanganiswa kokuphathwa kwedijithali kwefekthri kanye nezinhlelo zokulawula izimboni, kanye nokuhlinzekwa okufanelekile kwezinsizakalo zezwi zegumbi lehhotela kuyizidingo eziyisisekelo zamakhasimende amanje.
Ukuze kufezeke umbono wokumbozwa kwekhampasi ebona konke, isizukulwane esisha samanethiwekhi ekhampasi ye-POL kufanele sihlangabezane nezidingo eziyisisekelo zamakhasimende njengokuvikeleka nokugcinwa kalula, kanye nekhono lekhompyutha eshumekiwe, i-PON ephansi, kanye nokuhlangana kwe-5G. .
Vula i-POL Campus Network
Kunethiwekhi yendabuko ye-POL, iOLTipayipi nje lokudlulisa isevisi, imisebenzi yemishini iyaqiniswa, futhi ukuthunyelwa kwesevisi entsha kunzima. Amakhasimende adinga ukutshalwa kwezimali okwengeziwe ukuze akhe amasistimu ebhizinisi afana nezinqamuleli zomlilo zenethiwekhi, izilawuli ezingenantambo, amasistimu okuphatha ulwazi, kanye nezinhlelo zolayini obumisiwe be-softswitch. Lezi zinhlelo zivame ukufakwa kumaseva ahlukene. Lawa madivayisi azimele akha inethiwekhi eyinkimbinkimbi, ekhulisa Izindleko zokusatshalaliswa kwenethiwekhi nokusebenza nokugcinwa.
Njengomhlinzeki ohamba phambili emhlabeni wemishini yenethiwekhi ye-PON, i-ZTE yethule ingqalasizinda ye-IT kuhleloOLTokokuqala. Ngokuklanywa kwebhodi elakhelwe ngaphakathi, i-ZTE ingakwazi ukwenza izinto ezibonakalayo ezizimele (ezifana ne-firewall, izilawuli ezingenantambo, njll.) njengoba kudingeka I-software ye-VNF isetshenziswa futhi ifakwe kunethiwekhi ye-PON, yakhe inethiwekhi evulekile elula. , kulula ukuyithuthukisa, kulula ukuyilungisa, futhi kulula ukungeza imisebenzi emisha. Izixazululo ezintsha zobuchwepheshe be-POL zizosiza amakhasimende akhe amanethiwekhi ekhampasi e-POL avulekile.
Inethiwekhi yekhampasi ye-POL evulekile idala inani elikhulu kumakhasimende.
Ukunika amandla ukuvikela: Faka i-firewall ebonakalayo ukuze usebenzise ukuqinisekiswa kwe-inthanethi nokuzivikela ekuhlaselweni kwenethiwekhi kubasebenzisi be-intranet.
I-Computing Empowerment: Sebenzisa i-Edge Computing ku-OLTukuze kuzuzwe ibhalansi engcono kakhulu phakathi kokusebenza nezindleko.
Ukuphatha nokulawula okungenantambo:OLTihlanganisa uhlelo lokusebenza lwe-vAC ukuze uthole ukuphathwa okuhlangene kwemishini ye-AP yekhampasi.
Ukusika kuya ekupheleni: Nikeza ngezinsiza zekhompuyutha ye-blade ukuze kuhlangatshezwane nezidingo zokusika futhi kuzuzwe izimfuneko zokuhlukaniswa okuphephile kanye nokuhlukaniswa kwe-QoS phakathi kwamasevisi ahlukene.
Yenza lula ukusebenza nokugcinwa: Yenza inethiwekhi ibe lula ngokusebenzisa i-virtualization, futhi umsebenzi wokusebenza nowokulungisa ugxile kakhuluOLTimishini, enciphisa ukusebenza kanye nomsebenzi wokulungisa.
Isixazululo sekhampasi ye-POL yokubambezeleka okuphansi
Ubuchwepheshe be-PON busebenzisa imodi yokusebenza ye-uplink TDM. Ukuze uthole okusanda kufinyelelwa noma okusanda kunikwa amandlaI-ONUngesikhathi, iOLTUhlangothi lwembobo ye-PON ludinga ukuvula iwindi njalo (njengamasekhondi angu-1 ukuya kwangu-10) ukuze iwindi elisha livuleke.I-ONUungaqedela ukubhaliswa okudingekayo ukuze ufinyeleleOLT, Ubude nezinye izinqubo. Ngesikhathi sokuvula iwindi, konkeAma-ONUesimweni esivamile sokusebenza misa ukuthumela idatha ye-uplink. Ngokwezinga, isikhathi sewindi lama-microseconds angu-250 sizobangela ukubambezeleka kwama-microseconds angu-250 ku-I-ONU.
Ukuze kuqedwe ukubambezeleka okubangelwa indlela yokubhalisa yewindi le-PON, i-ZTE incike eminyakeni yayo yokunqwabelana emkhakheni wezobuchwepheshe we-PON, kulandela isiphakamiso sokuqala nokukhishwa kwesixazululo se-Combo PON, futhi iphakamisa ngendlela entsha isisombululo se-PON esingabambeki kakhulu. Kusixazululo se-PON se-low-latency, iOLTUhlangothi lisebenzisa i-Combo PON, kanye neI-ONUuhlangothi lwethula ukubambezeleka okuphansiI-ONU. Isiteshi se-PON se-10G se-Combo PON sisetshenziselwa izinsizakalo zokudlulisela phambili, futhi isiteshi se-GPON sinikezelwe ekulawuleni nasekulawuleni ulwazi lwe-PON, okunciphisa kakhulu ukubambezeleka kokuthunyelwa kwesevisi. Ukubambezeleka kwe-10G PON kwehlisiwe kusuka kuma-millisecond kuya ngaphansi kwama-microseconds ayi-100, kuhlangabezana nezidingo zokubambezeleka eziphansi zokulawulwa kwezimboni.
Ubuchwepheshe be-PON obubambezeleke kancane bunweba inkambu yesicelo se-PON ezinkambini ezinezidingo zokulibaziseka ezinzima, ezibeka isisekelo sokwakha inethiwekhi yekhampasi ebona konke.
Ukuhlangana kwenethiwekhi yekhampasi ye-POL kanye nobuchwepheshe be-5G
Uma kuqhathaniswa ne-Wi-Fi, i-5G inezinzuzo ezimbili zokubambezeleka okuphansi nokuphikisana nokuphazanyiswa. Kuwumkhuba ukuwusebenzisa kunethiwekhi yangasese yekhempasi, futhi imboni iwuhlola ngenkuthalo. Isiteshi esikhulu sangaphandle se-5G kanye nohlelo oluncane lwegumbi lusatshalaliswa ekhempasini ye-POL evulekile. Ngamaphoyinti okuvama akhethekile, ingaxazulula izimfuneko zesimo i-Wi-Fi engakwazi ukuhlangabezana nazo.OLTingahlanganisa i-5G UPF engasindi futhi ifinyelele izikhungo ze-5G DU ukuze yenze isixazululo se-POL + 5G esinezintambo nesingenantambo esihlanganisiwe sesizukulwane esilandelayo sekhampasi.
Ithembele emandleni ezixazululo eziphelele zokuphela-kuya-ekupheleni, i-ZTE ihlela ukuhambisa ezindaweni ezibalulekile njengokuphatha nokulawula, i-PON,amaswishi, kanye ne-5G, futhi ngokuqhubekayo ikhuthaza ukuvela kwezobuchwepheshe kwezixazululo zenethiwekhi ye-POL yebhizinisi le-campus evulekile futhi isebenzisa umbono "we-5G ishintsha umphakathi".
