Ntchito yapano ya netiweki ya DCI (Gawo Loyamba)

Netiweki ya DCI itayambitsa ukadaulo wa OTN, ndizofanana ndi kuwonjezera gawo lonse la ntchito lomwe silinakhalepo kale pankhani yogwira ntchito.Netiweki yapakatikati ya data ndi netiweki ya IP, yomwe ndi yaukadaulo waukadaulo wapaintaneti.OTN mu DCI ndi ukadaulo wosanjikiza wakuthupi, ndipo momwe mungagwirire ntchito ndi IP wosanjikiza mwaubwenzi komanso yosavuta ndi njira yayitali yogwirira ntchito.

Pakadali pano, cholinga cha OTN-based operation ndi chofanana ndi cha subsystem iliyonse ya data center.Zonsezi ndi cholinga chofuna kupititsa patsogolo mphamvu zazinthu zomwe zimayikidwa muzitsulo zotsika mtengo komanso kupereka chithandizo chabwino kwambiri cha ntchito zakumtunda.Kupititsa patsogolo kukhazikika kwa dongosolo loyambira, kuwongolera magwiridwe antchito ndi kukonza bwino, kuthandizira pakugawika kwabwino kwazinthu, kupanga zomwe zidaperekedwa kuti zigwire ntchito yayikulu, ndikugawa chuma chomwe sanagwiritse ntchito moyenera.

Kugwira ntchito kwa OTN makamaka kumakhudza magawo angapo: kasamalidwe ka data, kasamalidwe ka zinthu, kasamalidwe ka masinthidwe, kasamalidwe ka ma alarm, kasamalidwe ka magwiridwe antchito, ndi kasamalidwe ka DCN.

1 Ntchito Data

Pangani ziwerengero pazambiri zolakwika, kusiyanitsa zolakwika za anthu, zolakwika za Hardware, zolakwika zamapulogalamu, ndi zolakwika za gulu lachitatu, ndikusanthula zowerengera pamitundu ya zolakwika zazikulu, pangani mapulani okonzekera, ndikutsegulirani njira yosinthira zolakwika pambuyo pokhazikika .Malinga ndi kusanthula kwa data yolakwika, dongosololi limakometsedwa kuti lizigwira ntchito zamtsogolo monga mapangidwe a zomangamanga ndi kusankha zida, kuti achepetse mtengo wogwirira ntchito pambuyo pake ndi kukonza.Kwa OTN, tsatirani ziwerengero za zolakwika kuchokera ku ma amplifiers owoneka bwino, ma board, ma module, ma multiplex, ma jumper a zida, ma trunk fibers, ma netiweki a DCN, ndi zina zotero, kutenga nawo gawo pazopanga, miyeso ya chipani chachitatu, ndi zina zambiri, ndikuchita zambiri kusanthula kwa deta yolondola kwambiri.Itha kuwonetsa bwino momwe intaneti ilili.

Pangani ziwerengero pakusintha kwa data, kusiyanitsa zovuta ndi zovuta zakusintha, kugawa antchito, ndikusintha molingana ndi njira yowunikira zofunikira, kusintha dongosolo, kuyika zenera, kudziwitsa ogwiritsa ntchito, kugwirira ntchito, ndikuwunikanso mwachidule, ndipo pamapeto pake mutha kupanga kusintha kosiyana Amagawidwa mazenera, ngakhale kukonzedwa kuti aphedwe masana, kotero kuti kugawa kwa ogwira ntchito kusintha kumakhala koyenera, kuchepetsa kupanikizika kwa ntchito ndi moyo, komanso kupititsa patsogolo chisangalalo cha akatswiri oyendetsa ntchito.Ikhozanso kuphatikizira ziwerengero zomaliza ndikuzigwiritsa ntchito ngati chiwongolero cha ogwira ntchito moyenera komanso luso lantchito.Nthawi yomweyo, imalolanso kusintha kwanthawi zonse kuti kukhale kokhazikika pakupanga ma standard ndi automation, kuchepetsa ndalama zosiyanasiyana.

Sungani ziwerengero pakugawa kwa ntchito za OTN kuti zikuthandizeni kudziwa kagwiritsidwe ntchito ka netiweki ndikuwongolera kagawidwe ka netiweki pamanetiweki ndi kagawidwe ka ntchito pambuyo pakuwonjezeka kwa bizinesi.Ngati mukupanga zovuta, mutha kudziwa kuti ndi njira yanji yomwe njira imodzi ikugwiritsa ntchito, monga maukonde akunja, intranet, HPC network, network service network, etc. kugwiritsa ntchito magalimoto ena abizinesi.Mitengo yosiyanasiyana ya bandwidth imagawidwa m'madipatimenti osiyanasiyana amabizinesi kuti awathandize kukhathamiritsa kuchuluka kwa kuchuluka kwa mabizinesi, kukonzanso ndikusintha njira zogwirira ntchito zochepa nthawi iliyonse, ndikukulitsa njira zamabizinesi ogwiritsidwa ntchito kwambiri.

Deta yokhazikika ya Statistical, yomwe ndi data yayikulu ya SLA, ilinso lupanga la Damocles pamutu wa ogwira ntchito ndi kukonza.Ziwerengero zokhazikika za OTN ziyenera kuzindikirika chifukwa cha chitetezo chawo.Mwachitsanzo, ngati njira imodzi ikusokonezedwa, chiwerengero chonse cha bandwidth pa IP layer sichidzakhudzidwa, kaya chidzaphatikizidwa mu SLA;ngati bandwidth ya IP ili ndi theka, koma bizinesiyo sidzakhudzidwa, kaya idzaphatikizidwa mu SLA;Kaya kulephera kwa njira imodzi kumaphatikizidwa mu SLA;kuwonjezeka kwa kuchedwa kwa njira yotetezera sikukhudza bandwidth ya intaneti, koma kumakhudza bizinesi, kaya ikuphatikizidwa mu SLA, ndi zina zotero.Mchitidwe wamba ndikudziwitsa mbali zabizinesi za zoopsa monga jitter ndikuchedwetsa kusintha musanamangidwe.SLA yamtsogolo imawerengedwa kutengera kuchuluka kwa mayendedwe olakwika * bandwidth ya njira imodzi yolakwika, yogawidwa ndi kuchuluka kwa mayendedwe * kuchuluka kwa bandwidth yofananira, kenako kuchulukitsidwa ndi Kutengera nthawi yomwe yakhudzidwa, mtengo womwe wapezeka. imagwiritsidwa ntchito ngati mulingo wowerengera wa SLA.

2 Kasamalidwe ka Katundu

Katundu wa zida za OTN amafunikiranso kasamalidwe ka moyo (kufika, pa intaneti, kupukuta, kuwongolera zolakwika), koma mosiyana ndi ma seva, ma switch switch ndi zida zina, kapangidwe ka zida za OTN ndizovuta kwambiri.Zida za OTN zimaphatikizapo matabwa ambiri ogwira ntchito, choncho m'pofunika kupanga njira yoyendetsera chuma chonse panthawi yoyang'anira.Pulogalamu yayikulu yoyang'anira chuma cha IP mu data center imachokera pa ma seva ndi masinthidwe, ndipo mlingo wa chipangizo cha master-kapolo udzakhazikitsidwa.Pamaziko awa a OTN, gawo la kapolo-kapolo lidzakhudza kasamalidwe ka utsogoleri, koma pali zigawo zambiri.Mulingo wowongolera umachitika makamaka ndi network element-> subrack-> board card-> module:

2.1.Network element ndi chida chenicheni, popanda zinthu zakuthupi.Imagwiritsidwa ntchito poyang'anira ndi mfundo yoyamba yomveka mu netiweki ya OTN, ndipo ndi ya gawo loyamba mu kasamalidwe ka netiweki ya OTN.Chipinda cha zida zakuthupi chikhoza kukhala ndi NE imodzi kapena ma NE angapo.Ma network ali ndi ma subrack angapo, monga ma optical layer subracks, magetsi osanjikiza magetsi, ndi ma multiplexer akunja ndi ma demultiplexers amawonedwanso ngati subrack.Subrack iliyonse imatha kulumikizidwa mndandanda ndipo ndi ya subrack mkati mwa tsamba limodzi lamaneti.Kuwerengera.Kuphatikiza apo, gawo la maukonde lilibe nambala ya SN, chifukwa chake liyenera kulumikizidwa ndi nsanja yoyang'anira pankhaniyi, makamaka ndi chidziwitso chomwe chili pamndandanda wogulira komanso nsanja yoyendetsera ntchito ndi kukonza, kuti mupewe kufufuza zinthu. zomwe sizikufanana.Kupatula apo, chinthu cha netiweki ndi chinthu chamtengo wapatali..

2.2.Chigawo chachikulu kwambiri chakuthupi cha zida za OTN ndi chassis, ndiye kuti, subrack, yomwe ndi gawo lachiwiri la gawo loyamba la netiweki.Ndi gawo lachiwiri, ndipo chinthu cha netiweki chimakhala ndi chipangizo chimodzi chocheperako.Ma subracks awa amagawidwa mumitundu yosiyanasiyana ya opanga osiyanasiyana, okhala ndi ntchito zosiyanasiyana, kuphatikiza ma subracks amagetsi, ma photon subracks, subracks general, ndi zina zotero.Subrack ili ndi nambala yeniyeni ya SN, koma nambala yake ya SN siyingapezeke mosavuta kudzera pa nsanja yoyang'anira maukonde, ndipo imatha kuyang'aniridwa patsamba.Sikovuta kusuntha ndikusintha subrack ikapita pa intaneti.Ma board osiyanasiyana amayikidwa mu subrack.

2.3.Mkati mwa gawo lachiwiri la OTN, pali malo enaake othandizira kuti akhazikitsidwe.Malowa ali ndi manambala ndipo amagwiritsidwa ntchito kuyika matabwa osiyanasiyana a ma network optical.Ma board awa ndiye maziko othandizira mautumiki a netiweki a OTN, ndipo gulu lililonse limatha kufunsa SN yake kudzera pamanetiweki oyang'anira.Ma board awa ndi gawo lachitatu mu kasamalidwe ka katundu wa OTN.Ma board a bizinesi osiyanasiyana ali ndi makulidwe osiyanasiyana, amakhala ndi mipata yosiyanasiyana, ndipo amakhala ndi ntchito zosiyanasiyana.Choncho, pamene bolodi ikufunika kuperekedwa ku gawo lachiwiri la unit subrack, nsanja ya chuma iyenera kulola bolodi imodzi kuti igwiritse ntchito mipata yambiri kapena theka kuti igwirizane ndi nambala za slot pa subrack.

2.4.Kasamalidwe ka chuma cha Optical module.Ma modules amadalira kugwiritsa ntchito matabwa a utumiki.Ma board onse abizinesi akuyenera kuloleza umwini wa ma module, koma si ma board onse a zida za OTN omwe ayenera kulumikizidwa mu ma module opangira, kotero ma board ayeneranso kuloledwa Palibe module yomwe ilipo.Gawo lililonse la optical lili ndi nambala ya SN, ndipo gawo lomwe limayikidwa pa bolodi liyenera kulumikizidwa ndi nambala ya doko la bolodi kuti mufufuze mosavuta malo.

Zonse izi zitha kusonkhanitsidwa kudzera mu mawonekedwe a kumpoto kwa pulatifomu yoyang'anira maukonde, ndipo kulondola kwa chidziwitso cha katundu kumatha kuyendetsedwa kudzera pakusonkhanitsa pa intaneti ndikutsimikizira popanda intaneti ndi kufananiza.Kuphatikiza apo, zida za OTN zimaphatikizanso zowongolera zowonera, zodumpha zazifupi, ndi zina zambiri. Zida zogwiritsira ntchitozi zitha kuyendetsedwa mwachindunji ngati zogwiritsidwa ntchito.
