Amahirwe nibibazo byurusobe rwibigo bya POL
Mu myaka yashize, mu iyubakwa ry’imiyoboro y’ikigo, ibisubizo bya POL (Passive Optical LAN) byarushijeho kuba amahitamo ya mbere y’abakiriya, kandi kubaka imiyoboro y’ibigo byose byahindutse imyumvire imwe y’inganda.Ugereranije na Ethernet LAN gakondo, POL ifite ibiranga umutekano muke, gukoresha ingufu nke, intera ndende, kuramba, umuyoboro woroheje no gukora no kubungabunga ibikorwa.Hashingiwe ku ishoramari rirambye hamwe no gukusanya ikoranabuhanga mu iterambere ry’umuyoboro wa PON ku isoko ryagutse, abashoramari bateza imbere kubaka umuyoboro wa POL muri parike.Kurugero, Ubushinwa bwa Telecom bwa mbere uburezi bwigenga bukoresha ikoranabuhanga rya PON, kandi inganda zamahoteri zimaze gukwirakwiza imiyoboro ya PON murwego runini.Urubuga rwa interineti rwinganda rwatanze igitekerezo cya PON yinganda kandi rwakoze ubuziranenge.
Ugereranije na gakondo murugo-rugari rwa PON rwinjira, POL ikoresha tekinoroji ya PON, ariko ihura nibidukikije bigoye kandi nibisabwa abakiriya benshi.Umuyoboro w'ikigo cya POL ufite ibimenyetso by'ibanze n'ibisabwa bikurikira.
1) Hariho ubwoko bwinshi bwa serivisi, harimo serivisi za interineti zo mu biro, serivisi zishinzwe gukurikirana umutekano, serivisi z’ijwi rya intranet, serivisi zo gukusanya amakuru mu nganda, hamwe na serivisi zigenga imiyoboro yihariye.
2) Gutandukanya uburyo butandukanye bwo kwinjira, harimo ONU nshya yoherejwe, imiyoboro ya Ethernet gakondo, imiyoboro idafite insinga, imiyoboro yo kugura amakuru mu nganda, nibindi.
3) Umutekano mwinshi nibisabwa byiringirwa.Ntigomba gusa kurwanya ibitero byurusobe rwo hanze, ahubwo igomba no gukumira abakoresha imbere batemewe no kwinjira kwa terefone itemewe.Ubwizerwe buhebuje busaba urwego-rwibikoresho hamwe n’ibikoresho byo kurinda ibicuruzwa, cyane cyane mu nganda, bisaba ko habaho 99,999%.
4) Gukora no gufata neza ibisabwa gucunga neza biroroshye kandi byihuse.Umuyoboro wikigo nisoko ryihariye.Urwego nyamukuru rukora rushobora kuba kubungabunga ibikorwa, abakozi, imitungo ya parike, cyangwa ibice byabakiriya.Kugirango ugabanye ibikorwa no kubungabunga ibiciro, kohereza ubucuruzi bigomba kuba byoroshye bishoboka kandi imikorere nogucunga bigomba kuba byoroshye bishoboka.
5) Kwinjizamo insinga kandi zidafite umugozi.Ikigo cya Wi-Fi gikwirakwiza gisaba kohereza umubare munini wibikoresho bya AP bidafite umugozi, harimo no kohereza imiyoboro yigenga ya 5G.POL igomba gukemura ibibazo byubuyobozi biterwa nibi bikoresho byurusobe rutandukanye.
6) Gukoresha tekinoroji yo kubara.Porogaramu isanzwe yo kubara ni amashusho yerekana amashusho.Ukurikije ibisabwa byumutekano, ibikoresho byo kubara bigomba koherezwa imbere yikigo.
7) Ibisabwa bitinze.Sisitemu yo kugenzura inganda ifite ibisobanuro bihanitse bisaba gutinda k'umurongo wo kugenzura kuba munsi ya milisegonda 1.Ubuhanga gakondo bwa PON ntibushobora kuzuza byuzuye ibisabwa.
Byongeye kandi, mubihe byihariye, imicungire yabapangayi benshi muri parike nini yinganda, guhuza imicungire yububiko bwa digitale hamwe na sisitemu yo kugenzura inganda, hamwe no gutanga serivisi nziza kumajwi yicyumba cya hoteri nibyo byifuzo byabakiriya ba none.
Kugirango tumenye icyerekezo cyo gukwirakwiza ikigo cyose, ibisekuru bishya byicyatsi kibisi cya POL bigomba guhuza ibyifuzo byibanze byabakiriya nkumutekano no kubungabunga byoroshye, hamwe nubushobozi bwa mudasobwa yashyizwemo, PON-itinda cyane, hamwe na 5G ihuza .
Fungura umuyoboro wa POL Campus
Mumuyoboro gakondo wa POL, OLT numuyoboro wohereza serivisi gusa, imikorere yibikoresho irakomeye, kandi kohereza serivisi nshya biragoye.Abakiriya bakeneye ishoramari ryinyongera kugirango bubake sisitemu yubucuruzi nka firewall yumurongo, umugenzuzi udafite umugozi, sisitemu yo gucunga amakuru, hamwe na sisitemu ya softswitch.Ubusanzwe sisitemu zashyizwe kuri seriveri zitandukanye.Ibi bikoresho byigenga bigize urusobe rugoye, byongera Ikiguzi cyo kohereza imiyoboro no gukora no kuyitaho.
Nka mbere ku isi itanga ibikoresho byurusobe rwa PON, ZTE yinjije ibikorwa remezo bya IT muri OLT kunshuro yambere.Hamwe nigishushanyo mbonera cyubatswe, ZTE irashobora kwifashisha ibikoresho byigenga byigenga (nkumuriro wumutekano, ibyuma bidafite umugozi, nibindi) nkuko bikenewe Porogaramu VNF ikoreshwa kandi igashyirwa mumurongo wa PON, ikora umuyoboro ufunguye byoroshye , byoroshye kuzamura, byoroshye guhindura, kandi byoroshye kongera imikorere mishya.Udushya twa tekinoroji ya POL izafasha abakiriya kubaka imiyoboro ya POL yikigo.
Gufungura ikigo cya POL ikigo gikora agaciro gakomeye kubakiriya.
Gushoboza umutekano: Shyiramo firewall kugirango ushyire mubikorwa kwemeza kumurongo no kwirinda ibitero byurusobe kubakoresha intranet.
Ubushobozi bwo Kubara: Kohereza impande zo kubara kuri OLT kugirango ugere ku buringanire bwiza hagati yimikorere nigiciro.
Gucunga no kugenzura bidasubirwaho: OLT ihuza porogaramu ya VAC kugirango imenye imiyoborere ihuriweho nibikoresho bya campus AP.
Gukata kugeza ku ndunduro: Gutanga ibikoresho byo kubara kugirango uhuze ibikenewe byo gukata no kugera kubisabwa byo kwigunga neza hamwe na QoS itandukanye hagati ya serivisi zitandukanye.
Koroshya imikorere no kuyitaho: Koroshya umuyoboro ukoresheje virtualisation, kandi ibikorwa no kubungabunga byibanze kubikoresho bya OLT, bigabanya imikorere no kubungabunga imirimo.
Umuvuduko muke wa POL igisubizo cyikigo
Tekinoroji ya PON ikoresha uburyo bwakazi bwo kuzamura TDM.Kugirango tumenye ONU nshya yinjiye cyangwa ifite ingufu mugihe, uruhande rwicyambu cya OLT PON rugomba gukingura idirishya buri gihe (nka buri masegonda 1 kugeza 10) kugirango ONU nshya irangize kwiyandikisha bisabwa kugirango ubone OLT, Ranging hamwe nizindi nzira.Mugihe cyo gufungura idirishya, ONUs zose zisanzwe zikora zihagarika kohereza amakuru ya uplink.Ukurikije ibisanzwe, igihe cyidirishya cya microseconds 250 bizatera ubukererwe bwa microseconds 250 kuri ONU.
Mu rwego rwo gukuraho ubukererwe bwatewe nuburyo bwo kwandikisha idirishya rya PON, ZTE yishingikiriza kumyaka yayo imaze yegeranya murwego rwikoranabuhanga rwa PON, nyuma yicyifuzo cya mbere no gusohora igisubizo cya Combo PON, ikanatanga uburyo bushya bwo gukemura igisubizo cya PON.Mubisubizo bito-PON igisubizo, uruhande rwa OLT rukoresha Combo PON, naho uruhande rwa ONU ruzana ubukererwe buke ONU.Umuyoboro wa 10G PON wa Combo PON ukoreshwa mugutanga serivisi, kandi umuyoboro wa GPON wahariwe kugenzura no gucunga amakuru ya PON, bigabanya cyane gutinda kwa serivisi.Gutinda kwa 10G PON byagabanutse kuva kuri milisekondi kugera kuri microseconds munsi ya 100, byujuje ibyangombwa bitinda byo kugenzura inganda.
Ikoreshwa rya tekinoroji ya PON yagura ikibanza cyo gusaba cya PON kumurima hamwe nibisabwa bitinze cyane, bitanga umusingi wo kubaka umuyoboro wuzuye wa optique.
Guhuza umuyoboro wikigo cya POL hamwe nikoranabuhanga rya 5G
Ugereranije na Wi-Fi, 5G ifite ibyiza bibiri byubukererwe buke no kurwanya kwivanga.Nuburyo bwo kubishyira mubikorwa byikigo cyigenga, kandi inganda zirimo kubishakisha.5G yo hanze ya macro sitasiyo & icyumba-sisitemu yoherejwe mumashuri afunguye POL.Binyuze mu ngingo zidasanzwe, irashobora gukemura ibisabwa Wi-Fi idashobora kuzuza.OLT irashobora guhuza 5G UPF yoroheje kandi ikagera kubikoresho bya 5G DU kugirango ikore POL + 5G insinga kandi idafite umugozi winjiza ibisekuruza bizaza.
Ashingiye ku bushobozi bwibisubizo byuzuye kugeza ku ndunduro, ZTE irateganya kohereza mubice byingenzi nko kuyobora no kugenzura, PON, switch, na 5G, kandi igakomeza guteza imbere ikoranabuhanga ryiterambere rya tekinoroji ya POL yikigo cya enterineti kandi igashyira mubikorwa icyerekezo. ya “5G ihindura sosiyete”.
