Mwayi ndi zovuta zama network a POL campus
M'zaka zaposachedwa, pomanga ma campus networks, mayankho a POL (Passive Optical LAN) akhala akusankha makasitomala, ndipo kumanga ma network a all-optical campus kwakhala kumvetsetsa kwamakampani. Poyerekeza ndi LAN yachikhalidwe ya Ethernet, POL ili ndi mawonekedwe achitetezo apamwamba, kugwiritsa ntchito mphamvu zochepa, mtunda wautali, moyo wautali, maukonde osavuta komanso magwiridwe antchito apakati ndi kukonza. Kutengera ndalama zanthawi yayitali komanso kuchuluka kwaukadaulo pakukula kwa netiweki ya PON pamsika wapanyumba, ogwira ntchito amalimbikitsa ntchito yomanga ma network a POL paki. Mwachitsanzo, China Telecom's FIRST education network network imagwiritsa ntchito ukadaulo wa PON, ndipo makampani amahotelo adaphimba kale ma network a PON pamlingo waukulu. Malo ogulitsa pa intaneti apereka lingaliro la PON yamakampani ndipo achita zoyimira.
Poyerekeza ndi ma netiweki amtundu wa PON apanyumba, POL amagwiritsa ntchito ukadaulo wa PON womwewo, koma amayang'anizana ndi malo ochezera ovuta kwambiri komanso zofunikira zamakasitomala. Netiweki yapampasi ya POL ili ndi izi ndi zofunika zotsatirazi.
1) Pali mitundu yambiri ya mautumiki, kuphatikizapo mautumiki apa intaneti a maofesi, ntchito zowunikira chitetezo, mautumiki a pa intaneti, ntchito zopezera deta ya mafakitale, ndi maphunziro achinsinsi pa intaneti.
2) Malo olowera osiyanasiyana, kuphatikiza omwe angotumizidwa kumeneONU, Ethernet yachikhalidwemasiwichi, ma AP opanda zingwe, malo opezera deta ya mafakitale, ndi zina.
3) Chitetezo chachikulu ndi zofunikira zodalirika. Siziyenera kungolimbana ndi kuwukiridwa kwa maukonde akunja, komanso kuletsa kulowa kwa ogwiritsa ntchito osaloledwa ndi anthu osavomerezeka. Kudalirika kwakukulu kumafuna chitetezo chapaintaneti komanso zida zodzitetezera, makamaka m'mafakitale, zomwe zimafuna kupezeka kwadongosolo kwa 99.999%.
4) Zofunikira zoyendetsera ntchito ndi kukonza ndizosavuta komanso zachangu. Network campus ndi msika wamba. Gulu lalikulu logwira ntchito litha kukhala kukonza kwa wogwiritsa ntchito, othandizira, malo osungira, kapena mayunitsi amakasitomala. Pofuna kuchepetsa ndalama zogwirira ntchito ndi kukonza, kutumizira bizinesi kuyenera kukhala kosavuta momwe zingathere ndipo kasamalidwe ka ntchito ndi kukonza kuyenera kukhala kosavuta momwe zingathere.
5) Integrated mawaya ndi opanda zingwe mwayi. Kufalikira kwa Wi-Fi ku Campus kumafuna kutumizidwa kwa zida zambiri zopanda zingwe za AP, kuphatikiza kutumizidwa kwa ma network achinsinsi a 5G. POL iyenera kuthana ndi zovuta zowongolera zomwe zimayambitsidwa ndi zida zapaintaneti izi.
6) Kugwiritsa ntchito ukadaulo wa komputa wam'mphepete. Ntchito yodziwika bwino yama komputa yam'mphepete ndikuzindikira zithunzi zowonera makanema. Kutengera ndi zofunikira zachitetezo cha data, zida zama komputa zam'mphepete ziyenera kuyikidwa mkati mwa kampasi.
7) Zofunikira zochepa za latency. Dongosolo loyang'anira mafakitale lomwe lili ndi mwatsatanetsatane kwambiri limafuna kuchedwa kwa maukonde owongolera kukhala osachepera 1 millisecond. Ukadaulo wakale wa PON sungathe kukwaniritsa zofunikira.
Kuonjezera apo, muzochitika zenizeni, kasamalidwe ka anthu ambiri m'mapaki akuluakulu a mafakitale, kuphatikiza kwa kayendetsedwe ka digito ya fakitale ndi machitidwe olamulira mafakitale, komanso kupereka bwino kwa mautumiki a mawu a chipinda cha hotelo ndizofunika kwambiri kwa makasitomala amakono.
Kuti muzindikire masomphenya a kufalikira kwa masukulu onse, mbadwo watsopano wa ma network obiriwira a POL uyenera kukwaniritsa zofunikira zamakasitomala monga chitetezo ndi kukonza kosavuta, komanso kuthekera kwa makompyuta ophatikizika, low-latency PON, ndi 5G convergence. .
Tsegulani POL Campus Network
Mu network yachikhalidwe ya POL, aOLTndi payipi yotumizira mautumiki, ntchito za zida zimakhazikika, ndipo kutumiza kwatsopano kumakhala kovuta. Makasitomala amafunikira ndalama zowonjezera kuti amange mabizinesi monga ma network firewall, owongolera opanda zingwe, kasamalidwe ka zidziwitso, ndi masinthidwe amizere a softswitch. Machitidwewa nthawi zambiri amaikidwa pa ma seva osiyana. Zipangizo zodziyimira pawokha izi zimapanga maukonde ovuta, kuchulukitsa Mtengo wotumizira ndikugwiritsa ntchito ndi kukonza.
Monga otsogola kwambiri padziko lonse lapansi pazida zapaintaneti za PON, ZTE idakhazikitsa maziko a IT muOLTkwa nthawi yoyamba. Ndi mapangidwe a bolodi lopangidwa ndi tsamba, ZTE imatha kugwiritsa ntchito zida zodziyimira pawokha (monga ma firewall, owongolera opanda zingwe, ndi zina) monga pakufunika Pulogalamu ya VNF imayikidwa ndikuyika mu netiweki ya PON, kupanga maukonde otseguka omwe ndi osavuta. , yosavuta kukweza, yosavuta kusintha, komanso yosavuta kuwonjezera ntchito zatsopano. Mayankho aukadaulo a POL athandiza makasitomala kupanga maukonde otseguka a POL.
Network yotseguka ya POL campus imapanga phindu lalikulu kwa makasitomala.
Kuthandizira chitetezo: Ikani zozimitsa moto kuti mugwiritse ntchito kutsimikizika kwapaintaneti ndikudzitchinjiriza motsutsana ndi ma netiweki kwa ogwiritsa ntchito intaneti.
Kupititsa patsogolo makompyuta: Gwiritsani ntchito makompyuta am'mphepeteOLTkuti akwaniritse bwino pakati pa ntchito ndi mtengo.
Kuwongolera ndi kuwongolera opanda zingwe:OLTimaphatikiza ntchito ya vAC kuti ikwaniritse kasamalidwe kogwirizana kwa zida zapasukulu za AP.
Kudula mpaka kumapeto: Perekani zida zamakompyuta kuti zikwaniritse zosowa za slicing ndikukwaniritsa zofunikira zodzipatula ndikusiyanitsa QoS pakati pa mautumiki osiyanasiyana.
Kuchepetsa magwiridwe antchito ndi kukonza: Kufewetsa maukonde kudzera mu virtualization, ndipo ntchito ndi kukonza zimayang'ana paOLTzida, zomwe zimachepetsa ntchito ndi kukonza ntchito.
Njira yotsika kwambiri ya POL campus solution
Tekinoloje ya PON imagwiritsa ntchito njira yogwirira ntchito ya uplink TDM. Kuti mupeze zomwe zangopezeka kumene kapena zoyendetsedwa kumeneONUmu nthawi,OLTMbali ya doko ya PON imayenera kutsegula zenera pafupipafupi (monga masekondi 1 mpaka 10) kuti zatsopano zitheke.ONUakhoza kumaliza kulembetsa kofunikira kuti mupeze maOLT, Kuthamanga ndi njira zina. Pa nthawi yotsegula zenera, zonseONUm'malo ogwirira ntchito imitsani kutumiza deta ya uplink. Malinga ndi muyezo, nthawi yazenera ya ma microseconds 250 ipangitsa kuchedwa kwa 250 microseconds kupita kuONU.
Kuti athetse kuchedwa komwe kumachitika chifukwa cha makina olembera zenera la PON, ZTE imadalira zaka zake zakudzikundikira m'munda waukadaulo wa PON, kutsatira lingaliro loyamba ndi kutulutsidwa kwa yankho la Combo PON, ndikupangira mwatsopano yankho la PON locheperako. Mu njira yotsika kwambiri ya PON, aOLTMbali imagwiritsa ntchito Combo PON, ndiONUmbali imayambitsa low-latencyONU. Njira ya 10G PON ya Combo PON imagwiritsidwa ntchito potumiza mautumiki, ndipo njira ya GPON imaperekedwa ku chidziwitso chowongolera ndi kasamalidwe ka PON, zomwe zimachepetsa kwambiri kuchedwa kwa Utumiki. Kuchedwa kwa 10G PON kwachepetsedwa kuchokera ku ma milliseconds kufika ku ma microseconds osachepera 100, kukwaniritsa zofunikira zochepa za latency ya kayendetsedwe ka mafakitale.
Ukadaulo wocheperako wa PON umakulitsa gawo logwiritsira ntchito PON m'minda ndi zofunika zochedwa kwambiri, zomwe zimayala maziko omanga ma network a all-optical campus network.
Kulumikizana kwa POL campus network ndi teknoloji ya 5G
Poyerekeza ndi Wi-Fi, 5G ili ndi maubwino awiri a low latency ndi anti-interference. Ndichizoloŵezi chochigwiritsa ntchito ku campus private network, ndipo makampani akufufuza mwakhama. The 5G outdoor macro station & room sub-system imayikidwa pamalo otseguka a POL. Kupyolera mu ma frequency apadera, imatha kuthetsa zofunikira zomwe Wi-Fi singathe kukwaniritsa.OLTikhoza kuphatikiza 5G UPF yopepuka ndikupeza malo a 5G DU kuti apange njira yothetsera POL + 5G yolumikizana ndi ma waya komanso opanda zingwe.
Kutengera kuthekera kwa mayankho athunthu, ZTE ikukonzekera kuyika m'malo ofunikira monga kasamalidwe ndi kuwongolera, PON,masiwichi, ndi 5G, ndipo amalimbikitsa mosalekeza kusinthika kwaukadaulo kwa mayankho otseguka a POL Enterprise campus network ndikukhazikitsa masomphenya a "5G amasintha anthu".
