Mikana uye matambudziko ePOL campus network
Mumakore achangopfuura, mukuvaka kwekampasi network, POL (Passive Optical LAN) mhinduro dzave kuwedzera kuve sarudzo yekutanga yevatengi, uye kuvakwa kweall-optical campus network kwave kunzwisisa kwakabatana kweindasitiri.Kana ichienzaniswa neyechinyakare Ethernet LAN, POL ine hunhu hwekuchengetedza kwakanyanya, kuderera kwesimba rekushandisa, kureba, hupenyu hwakareba, kurerutswa network uye centralized mashandiro nekugadzirisa.Zvichienderana nekudyara kwenguva refu uye kuunganidza tekinoroji mukuvandudza kwePON yekuwana network mumusika wakafara wemba, vashandisi vanoshingairira kusimudzira kuvakwa kwePOL network mupaki.Semuyenzaniso, China Telecom's FIRST dzidzo yakavanzika network inoshandisa PON tekinoroji, uye indasitiri yemahotera yakatovhara maPON network pamwero mukuru.Iyo indasitiri yeInternet yeindasitiri yakaronga iyo pfungwa yeindasitiri PON uye yakaita kumira.
Kuenzaniswa neyechinyakare pamba-pase PON yekuwana network, POL inoshandisa imwecheteyo PON tekinoroji, asi inotarisana neyakaomarara nharaunda yetiweki uye yepamusoro zvinodiwa nevatengi.Iyo POL campus network ine anotevera akakosha maitiro uye zvinodiwa.
1) Kune akawanda marudzi emasevhisi, anosanganisira hofisi Internet masevhisi, kuchengetedzwa kwekutarisa masevhisi, intranet izwi masevhisi, maindasitiri ekutora data masevhisi, uye dzidzo yakavanzika network masevhisi.
2) Diversified access terminals, kusanganisira ichangobva kuiswa ONUs, yechinyakare Ethernet switch, isina waya APs, maindasitiri data acquisition terminals, nezvimwe.
3) Kuchengetedza kwakanyanya uye kuvimbika zvinodiwa.Haifanire kungoramba kurwiswa kwenetiweki yekunze chete, asiwo kudzivirira kupinda kwemukati kwemushandisi zvisiri pamutemo uye kuwana isina kutenderwa terminal.Kuvimbika kwepamusoro kunoda network-level uye michina-level redundancy kuchengetedzwa, kunyanya mundima yeindasitiri, iyo inoda 99.999% system kuwanikwa.
4) Kushanda uye kugadzirisa manejimendi zvinodiwa zviri nyore uye nekukurumidza.Iyo campus network imusika wakasarudzika.Muviri mukuru unoshanda unogona kuve gadziriso yemushandisi, vamiririri, zvivakwa zvepaki, kana zvikamu zvevatengi.Kuti uderedze mutengo wekushanda nekugadzirisa, kutumirwa kwebhizinesi kunofanirwa kunge kuri nyore sezvinobvira uye kushanda nekugadzirisa manejimendi kunofanirwa kuve nyore sezvinobvira.
5) Yakabatanidzwa wired uye isina waya yekuwana.Campus Wi-Fi coverage inoda kuiswa kwenhamba huru yewireless AP zvishandiso, kusanganisira kutumirwa kwe5G yakavanzika network.POL inofanirwa kugadzirisa matambudziko ekutonga anounzwa neaya heterogeneous network zvishandiso.
6) Kushandisa edge komputa tekinoroji.Iyo yakajairika kumucheto komputa application ndeye vhidhiyo yekutarisa mufananidzo kuzivikanwa.Zvichienderana nezvinodiwa zvekuchengetedza data, edge computing zvivakwa zvinofanirwa kuiswa mukati mekambasi.
7) Low latency zvinodiwa.Iyo indasitiri yekudzora sisitimu ine yakakwirira chaiyo inoda kunonoka kweiyo control network kuve isingasviki 1 millisecond.Iyo yechinyakare PON tekinoroji haigone kuzadzisa zvizere zvinodiwa.
Pamusoro pezvo, mumamiriro ezvinhu chaiwo, manejimendi akawanda mumapaki makuru emaindasitiri, kubatanidzwa kwefekitori yedhijitari manejimendi uye maindasitiri ekudzora masisitimu, uye kupihwa kuri nyore kwehotera yekamuri masevhisi ndizvo zvinodikanwa zvevatengi vemazuva ano.
Kuti uone chiono chezvese-optical campus coverage, chizvarwa chitsva chegirinhi POL campus network chinofanira kusangana nezvinodiwa zvevatengi sekuchengetedza uye kugadzirisa zviri nyore, pamwe nekugona kweyakadzamirwa komputa, yakaderera-latency PON, uye 5G convergence. .
Vhura POL Campus Network
Mune yechinyakare POL network, iyo OLT ingori sevhisi yekufambisa pombi, mabasa emidziyo anosimbiswa, uye kutsva kwesevhisi kwakaoma.Vatengi vanoda imwe mari yekudyara kuvaka masisitimu ebhizinesi senge network firewall, mawireless controllers, information management system, uye softswitch yakatarwa-mutsara masisitimu.Aya masisitimu anowanzo kuiswa pamaseva akasiyana.Aya maturusi akazvimirira anoumba network yakaoma, ichiwedzera Mutengo wekutumira network uye kushanda uye kugadzirisa.
Semupi anotungamira pasirese wePON network michina, ZTE yakaunza IT zvivakwa muOLT kekutanga.Nekugadzirwa kweakavakirwa-mukati blade board, ZTE inogona kuona yakazvimirira michina yemuviri (senge chengetedzo firewalls, mawireless controllers, nezvimwewo) sezvinodiwa Iyo software VNF inoiswa uye yakaiswa muPON network, ichigadzira network yakavhurika iri nyore. , nyore kusimudzira, nyore kugadzirisa, uye nyore kuwedzera mabasa matsva.Innovative POL tekinoroji mhinduro ichabatsira vatengi kuvaka yakavhurika POL campus network.
Iyo yakavhurika POL campus network inogadzira yakawanda kukosha kune vatengi.
Chengetedzo yekugonesa: Isa chaiyo firewall yekushandisa online chokwadi uye dziviriro pakurwisa network yevashandisi ve intranet.
Computing Empowerment: Deploy edge computing paOLT kuti uwane yakanakisa chiyero pakati pekuita uye mutengo.
Wireless manejimendi uye kutonga: OLT inobatanidza vAC application kuona yakabatana manejimendi yekambasi AP michina.
Kupera-kusvika-kumagumo slicing: Ipa blade computing zviwanikwa kuti zvizadzise zvinodikanwa zvekucheka uye kuzadzisa zvinodiwa zvekuzviparadzanisa zvakachengeteka uye kusiyanisa QoS pakati pemasevhisi akasiyana.
Rerutsa kushanda nekugadzirisa: Rerusa network kuburikidza nekuona, uye kushanda uye kugadzirisa basa rinonangidzirwa pamidziyo yeOLT, iyo inoderedza kushanda nekugadzirisa basa.
Yakaderera-latency POL campus mhinduro
Iyo PON tekinoroji inoshandisa nzira yekushanda yeuplink TDM.Kuti uwane ichangobva kuwanikwa kana kuti ichangobva kuve nemagetsi ONU nekufamba kwenguva, iyo OLT PON port side inoda kuvhura hwindo nguva nenguva (sesese 1 kusvika 10 masekonzi) kuitira kuti ONU itsva ipedze kunyoreswa kunodiwa kuti uwane iyo OLT , Ranging. nemamwe maitiro.Munguva yekuvhura hwindo, ese maONU mune yakajairika kushanda mamiriro anomisa kutumira uplink data.Zvinoenderana nechiyero, nguva yehwindo ye250 microseconds ichakonzera kunonoka kwe250 microseconds kuONU.
Kuti ibvise kunonoka kunokonzerwa nePON hwindo rekunyoresa michina, ZTE inovimba nemakore ayo ekuunganidza mumunda wePON tekinoroji, ichitevera chirevo chekutanga uye kuburitswa kweCombo PON mhinduro, uye nehunyanzvi inopa yakaderera-latency PON mhinduro.Mune yakaderera-latency PON mhinduro, rutivi rweOLT runoshandisa Combo PON, uye rutivi rweONU runosuma yakaderera-latency ONU.Iyo 10G PON chiteshi cheCombo PON inoshandiswa pakutumira masevhisi, uye iyo GPON chiteshi yakatsaurirwa kune kutonga uye manejimendi ruzivo rwePON, iyo inoderedza zvakanyanya kunonoka kweSevhisi kunonoka.Iyo 10G PON kunonoka yakaderedzwa kubva kumamilliseconds kusvika pasi pe100 microseconds, ichisangana yakaderera latency zvinodiwa zvekutonga kwemaindasitiri.
Iyo yakaderera-latency yePON tekinoroji inowedzera nzvimbo yekushandisa yePON kuminda ine zvakanyanya kunonoka zvinodiwa, izvo zvinoisa hwaro hwekuvaka iyo yose-optical campus network.
Convergence yePOL campus network uye 5G tekinoroji
Kuenzaniswa neWi-Fi, 5G ine mabhenefiti maviri epasi latency uye anti-kupindira.Iyo itsika yekuishandisa kune iyo campus yakavanzika network, uye iyo indasitiri iri kushingaira kuiongorora.Iyo 5G yekunze macro chiteshi & kamuri sub-system inoiswa munzvimbo yakavhurika yePOL campus.Kuburikidza neakakosha mapoinzi mapoinzi, inogona kugadzirisa mamiriro ezvinhu ayo Wi-Fi asingakwanise kusangana nawo.OLT inogona kubatanidza lightweight 5G UPF uye kuwana 5G DU zvivakwa kugadzira POL + 5G wired uye isina waya yakabatanidzwa inotevera-chizvarwa campus solution.
Zvichivimba nekugona kwekupedzisira-kusvika-kumagumo mhinduro dzakakwana, ZTE inoronga kuendesa munzvimbo dzakakosha senge manejimendi uye kutonga, PON, switch, uye 5G, uye inoramba ichisimudzira shanduko yetekinoroji yekuvhurika POL enterprise campus network mhinduro uye inoshandisa chiratidzo. ye "5G inoshandura nzanga".
