    Vula inethiwekhi ye-POL yekhampasi exhasa ukuhlangana kwe-5G

    Ixesha lokuposa: Dec-27-2019

    Amathuba kunye nemingeni yothungelwano lweekhampasi zePOL

    Kwiminyaka yakutshanje, ekwakhiweni kwamanethiwekhi e-campus, i-POL (i-Passive Optical LAN) izisombululo ziye zanda zibe yinto yokuqala yokukhetha abathengi, kwaye ukwakhiwa kweenethiwekhi ze-campus zokukhanya kuye kwaba yingqiqo edibeneyo yoshishino. Xa kuthelekiswa ne-LAN ye-Ethernet yendabuko, i-POL ineempawu zokhuseleko oluphezulu, ukusetyenziswa kwamandla aphantsi, umgama omde, ubomi obude, inethiwekhi elula kunye nokusebenza okuphakathi kunye nokugcinwa. Ngokusekelwe kutyalo-mali lwexesha elide kunye nokuqokelela iteknoloji ekuphuhliseni inethiwekhi yokufikelela kwi-PON kwimarike yasekhaya, abaqhubi bakhuthaza ngokunyanisekileyo ukwakhiwa kwenethiwekhi ye-POL epakini. Umzekelo, i-China Telecom 's Imfundo yokuQALA inethiwekhi yabucala isebenzisa iteknoloji yePON, kwaye ishishini lehotele sele ligubungele iinethiwekhi zePON ngomlinganiselo omkhulu. Intsimi ye-Intanethi ye-intanethi iphakamise ingcamango ye-PON yoshishino kwaye iqhube umgangatho.

    Xa kuthelekiswa nothungelwano lokufikelela kwiPON lwasekhaya ngokubanzi, i-POL isebenzisa itekhnoloji yePON efanayo, kodwa ijongene nemeko yonxibelelwano entsonkothileyo kunye neemfuno eziphezulu zabathengi. Inethiwekhi ye-POL campus ineempawu ezisisiseko ezilandelayo kunye neemfuno.

    I-1) Kukho iintlobo ezininzi zeenkonzo, ezibandakanya iinkonzo ze-intanethi ze-intanethi, iinkonzo zokubeka iliso zokhuseleko, iinkonzo zelizwi le-intranethi, iinkonzo zokufumana idatha yezoshishino, kunye neenkonzo zenethiwekhi zabucala zemfundo.

    2) Iitheminali zokufikelela kwiindlela ezahlukeneyo, kubandakanywa nokusasazwa ngokutshaIi-ONU, i-Ethernet yemveliiiswitshi, ii-APs ezingenazingcingo, iitheminali zokufumana idatha yeshishini, njl.

    3) Ukhuseleko oluphezulu kunye neemfuno zokuthembeka. Akufunekanga ixhathise kuphela uhlaselo lwenethiwekhi yangaphandle, kodwa kwakhona ithintele ukufikelela komsebenzisi ongekho mthethweni wangaphakathi kunye nokufikelela kwi-terminal engagunyaziswanga. Ukuthembeka okuphezulu kufuna ukukhuselwa kwe-network-level kunye nezixhobo-level redundancy, ngokukodwa kwi-industrial field, efuna i-99.999% yokufumaneka kwenkqubo.

    I-4) Iimfuno zokulawula ukusebenza kunye nokugcinwa zilungele kwaye zikhawuleza. Uthungelwano lwekhampasi yimarike ecacileyo. Elona qumrhu lisebenzayo linokuba lulondolozo lomsebenzisi, ii-arhente, iipropati zepaki, okanye iiyunithi zabathengi. Ukuze kuncitshiswe iindleko zokusebenza kunye nokugcinwa, ukuthunyelwa kweshishini kufuneka kube lula kangangoko kwaye ulawulo kunye nokusebenza nokugcinwa kufuneka kube lula ngokusemandleni.

    5) Ufikelelo oludityanisiweyo lwengcingo kunye nolungenacingo. I-Campus Wi-Fi coverage idinga ukuthunyelwa kwenani elikhulu lezixhobo ezingenazintambo ze-AP, kubandakanywa nokuthunyelwa kweenethiwekhi zangasese ze-5G. I-POL kufuneka ijongane nemingeni yolawulo eyenziwa zezi zixhobo zothungelwano zahlukeneyo.

    6) Ukusetyenziswa kweteknoloji ye-edge computing. Usetyenziso lwekhompuyutha oluqhelekileyo lujongwa kwividiyo ecupha umfanekiso. Ngokusekwe kwiimfuno zokhuseleko lwedatha, izibonelelo ze-edge computing kufuneka zifakwe ngaphakathi ekhampasini.

    I-7) Iimfuno eziphantsi ze-latency. Inkqubo yokulawula i-industrial echanekileyo ephezulu idinga ukulibaziseka kwenethiwekhi yokulawula ukuba ibe ngaphantsi kwe-1 millisecond. Itekhnoloji yePON yemveli ayinakuhlangabezana ngokupheleleyo neemfuno.

    Ukongezelela, kwiimeko ezithile, ulawulo lwabaqeshi abaninzi kwiipaki ezinkulu zoshishino, ukuhlanganiswa kokulawulwa kwedijithali kwefektri kunye neenkqubo zokulawula imboni, kunye nokubonelela ngokufanelekileyo kweenkonzo zelizwi zegumbi lehotele zizinto ezisisiseko zabathengi bangoku.

    Ukuqonda umbono wekhampasi yonke i-optical coverage, isizukulwana esitsha sothungelwano lwe-POL campus kufuneka sihlangabezane neemfuno ezisisiseko zabathengi ezifana nokhuseleko kunye nokugcinwa lula, kunye nokukwazi ukusebenzisa i-computing edibeneyo, i-low-latency PON, kunye ne-5G convergence. .

    Vula i-POL Campus Network

    Kwinethiwekhi ye-POL yemveli, iOLTngumbhobho wothumelo lwenkonzo nje, imisebenzi yezixhobo iyaqiniswa, kwaye nokusasazwa kwenkonzo entsha kunzima. Abathengi bafuna utyalo-mali olongezelelweyo ukwakha iinkqubo zoshishino ezifana ne-firewall yenethiwekhi, abalawuli abangenazintambo, iinkqubo zokulawula ulwazi, kunye neenkqubo ze-softswitch ezisisigxina. Ezi nkqubo ziqhele ukufakwa kwiiseva ezahlukeneyo. Ezi zixhobo ezizimeleyo zenza uthungelwano olunzima, ukwandisa Iindleko zokuthunyelwa kwenethiwekhi kunye nokusebenza kunye nokugcinwa.

    Njengomboneleli okhokelayo wehlabathi wezixhobo zenethiwekhi yePON, iZTE yazisa isiseko se-IT kwiOLTokokuqala. Ngoyilo lwebhodi yeblade eyakhelwe-ngaphakathi, i-ZTE inokwenza izixhobo ezibonakalayo ezizimeleyo (ezifana ne-firewall, abalawuli abangenazintambo, njl. njl.) njengoko kufuneka I-software ye-VNF isetyenziswe kwaye ifakwe kwinethiwekhi ye-PON, yenza inethiwekhi evulekileyo elula. , kulula ukuyiphucula, kulula ukuyilungisa, kwaye kulula ukongeza imisebenzi emitsha. Izisombululo ezintsha zeteknoloji ye-POL ziya kunceda abathengi bakhe iinethiwekhi ezivulekileyo ze-POL.

    Inethiwekhi ye-POL evulekileyo yekhampasi yenza ixabiso elininzi kubathengi.

    Uncedo lokhuseleko: Fakela i-firewall ebonakalayo ukuphumeza uqinisekiso lwe-intanethi kunye nokukhusela kuhlaselo lwenethiwekhi kubasebenzisi be-intranet.

    UXhotyiso lweKhompyutha: Beka i-edge computing kwiOLTukufezekisa ibhalansi engcono phakathi kokusebenza kunye neendleko.

    Ulawulo olungenacingo kunye nolawulo:OLTidibanisa isicelo se-VAC ukuqonda ulawulo olumanyeneyo lwezixhobo ze-AP zekhampasi.

    Ukuqhawula ukuphela kokuphela: Ukubonelela ngezixhobo zekhompyutheni ye-blade ukuhlangabezana neemfuno zokuqhawula kunye nokufezekisa iimfuno zokuzihlukanisa ngokukhuselekileyo kunye nokwahlula i-QoS phakathi kweenkonzo ezahlukeneyo.

    Yenza lula ukusebenza kunye nokugcinwa: Yenza lula inethiwekhi ngokusebenzisa i-virtualization, kwaye umsebenzi kunye nomsebenzi wokulondoloza ugxile kwiOLTizixhobo, ezinciphisa ukusebenza kunye nokugcinwa komsebenzi.

    Isisombululo sekhampasi ye-POL esezantsi

    I-teknoloji ye-PON isebenzisa indlela yokusebenza ye-uplink TDM. Ukuze ufumanise into entsha efunyenweyo okanye enikwe amandlaI-ONUekuhambeni kwexesha, iOLTIcala lezibuko le-PON lidinga ukuvula ifestile rhoqo (njengemizuzwana eyi-1 ukuya kweyi-10) ukuze entshaI-ONUungagqibezela ubhaliso olufunekayo ukufikelela kwiOLT, Uluhlu kunye nezinye iinkqubo. Ngexesha lokuvula ifestile, zonkeIi-ONUkwimeko yokusebenza eqhelekileyo nqumamisa ukuthumela idatha ye-uplink. Ngokomgangatho, ixesha lefestile le-250 microseconds liya kubangela ukulibaziseka kwe-250 microseconds ukuyaI-ONU.

    Ukuze kupheliswe ukulibaziseka okubangelwa yindlela yokubhalisa yefestile ye-PON, i-ZTE ixhomekeke kwiminyaka yayo yokuqokelela kwi-PON yezobuchwepheshe kwintsimi, emva kwesiphakamiso sokuqala kunye nokukhululwa kwesisombululo se-Combo PON, kwaye iphakamisa ngokutsha isisombululo se-PON ephantsi. Kwisisombululo se-PON esisezantsi, iOLTicala isebenzisa Combo PON, kunyeI-ONUicala lazisa i-low-latencyI-ONU. Isiteshi se-PON ye-10G ye-Combo PON isetyenziselwa ukuthunyelwa kweenkonzo, kwaye i-GPON ishaneli inikezelwe kulawulo nolwazi lolawulo lwe-PON, olunciphisa kakhulu ukulibaziseka kokuthunyelwa kweNkonzo. Ukulibaziseka kwe-PON ye-10G kuncitshiswe ukusuka kwi-milliseconds ukuya ngaphantsi kwe-microseconds ye-100, ukuhlangabezana neemfuno eziphantsi zokulinda ukulawulwa kwezoshishino.

    I-teknoloji ye-PON ye-low-latency yandisa intsimi yesicelo se-PON kwiinkalo ezineemfuno zokulibaziseka ezinzima, ezibeka isiseko sokwakha inethiwekhi ye-campus ye-optical.

    Ukudityaniswa kwenethiwekhi ye-POL campus kunye ne-5G iteknoloji

    Xa kuthelekiswa ne-Wi-Fi, i-5G ineenzuzo ezimbini ze-latency ephantsi kunye ne-anti-interference. Lumkhwa wokuwusebenzisa kuthungelwano lwabucala lwekhampasi, kwaye ishishini liyiphonononga ngokukhutheleyo. Isikhululo esikhulu sangaphandle se-5G kunye nenkqubo encinci yegumbi ibekwe kwikhampasi yePOL evulekileyo. Ngokusebenzisa amanqaku akhethekileyo amaza, inokusombulula iimfuno zemeko apho iWi-Fi ayinakuhlangabezana nazo.OLTinokudibanisa i-5G ye-UPF ekhaphukhaphu kunye nokufikelela kumaziko e-5G DU ukwenza i-POL + 5G enentambo kunye ne-wireless edibeneyo isisombululo se-campus esilandelayo.

    Ukuxhomekeka kwikhono lezisombululo ezipheleleyo zokuphela, i-ZTE iceba ukuhambisa kwiindawo ezibalulekileyo ezifana nokulawula kunye nokulawula, i-PON,iiswitshi, kunye ne-5G, kwaye ngokuqhubekayo ikhuthaza ukuziphendukela kwezobuchwepheshe kwi-POL evulekileyo yezisombululo zenethiwekhi ye-campus yeshishini kwaye iphumeze umbono "we-5G utshintsho kuluntu".
