Malinga ndi mawonekedwe awa, pali njira ziwiri za DCI:
1. Gwiritsani ntchito zida zoyera za DWDM, ndipo gwiritsani ntchito mtundu wa optical module + DWDM multiplexer/demultiplexer pakusintha.Pankhani ya single-channel 10G, mtengo wake ndi wotsika kwambiri, ndipo zosankha zamagulu ndizochuluka.Mtundu wa kuwala kwa 10G uli m'nyumba Zapangidwa kale, ndipo mtengo wake ndi wotsika kwambiri (kwenikweni, dongosolo la 10G DWDM linayamba kutchuka zaka zingapo zapitazo, koma ndi kufika kwa zofunikira zina zazikulu za bandwidth, zinali nazo. kuti athetsedwe, ndipo gawo la kuwala kwa mtundu wa 100G linali lisanapezeke.) Pakalipano, 100G yangoyamba kuonekera ku China yokhudzana ndi ma modules optical color, ndipo mtengo wake siwochepa, koma nthawi zonse udzapereka chithandizo champhamvu. ku netiweki ya DCI.
2. Gwiritsani ntchito zida za OTN zotumizira kwambiri, ndi 220V AC, zida za 19-inchi, 1 ~ 2U m'mwamba, ndipo kutumizidwa ndikosavuta.Ntchito ya SD-FEC imazimitsidwa kuti ichepetse kuchedwa, ndipo chitetezo chamayendedwe pagawo la kuwala chimagwiritsidwa ntchito kuti chikhale chokhazikika, ndipo mawonekedwe owongolera a kumpoto amathandiziranso luso lachitukuko cha ntchito zowonjezera zida.Komabe, ukadaulo wa OTN ukadali wosungidwa, ndipo kasamalidwe kadzakhalabe kovuta.
Kuphatikiza apo, zomwe omanga ma netiweki amtundu woyamba wa DCI akuchita pakadali pano ndikuchotsa ma netiweki a DCI, kuphatikiza kuphatikizika kwa optical pa wosanjikiza 0 ndi magetsi pa wosanjikiza 1, komanso zida za NMS ndi zida za opanga azikhalidwe. .kudula.Njira yachikhalidwe ndi yoti zida zopangira magetsi za wopanga wina ziyenera kugwirizana ndi zida zowonera za wopanga yemweyo, ndipo zida za Hardware ziyenera kugwirizana ndi mapulogalamu amtundu wa NMS owongolera.Njira yachikhalidwe iyi ili ndi zovuta zingapo zazikulu:
1. Ukadaulo watsekedwa.Mwachidziwitso, mulingo wa optoelectronic ukhoza kuchotsedwa wina ndi mzake, koma opanga miyambo mwadala samachotsa dala kuti athe kuwongolera ulamuliro waukadaulo.
2. Mtengo wa ma netiweki opatsirana a DCI umakhala wokhazikika pagawo lamagetsi amagetsi.Mtengo woyamba wa dongosololi ndi wotsika, koma mphamvu ikakulitsidwa, wopanga adzakweza mtengowo powopsezedwa ndi luso lapadera, ndipo mtengo wokulirapo udzawonjezeka kwambiri.
3. Pambuyo pa kuwala kwa magetsi a DCI transmission network akugwiritsidwa ntchito, angagwiritsidwe ntchito ndi zida za magetsi za wopanga yemweyo.Kugwiritsidwa ntchito kwa zida ndi zotsika, zomwe sizikugwirizana ndi momwe ma network akugwiritsidwira ntchito, komanso sizikugwirizana ndi ndondomeko yogwirizana ya optical layer resource.Decoupled Optical layer imayikidwa mosiyana koyambirira kwa ntchito yomanga, ndipo sikuli ndi malire ndi kugwiritsa ntchito mtsogolo kwa gulu limodzi la optical layer ndi opanga angapo, ndikuphatikiza mawonekedwe a kumpoto kwa mawonekedwe owoneka bwino ndi ukadaulo wa SDN kuti achite kuwongolera njira. zothandizira pa optical layer , Sinthani kusinthasintha kwa bizinesi.
4. The zida maukonde seamlessly zikugwirizana ndi Intaneti kampani kasamalidwe nsanja Intaneti mwachindunji kudzera dongosolo deta ya YANGmodel, amene amapulumutsa ndalama chitukuko cha nsanja kasamalidwe ndi kuchotsa NMS mapulogalamu operekedwa ndi Mlengi, amene bwino dzuwa kusonkhanitsa deta ndi kasamalidwe ka maukonde.kasamalidwe bwino.
Choncho, optoelectronic decoupling ndi njira yatsopano yopangira ma netiweki a DCI.M'tsogolomu, mawonekedwe a kuwala kwa DCI transmission network akhoza kukhala teknoloji ya SDN yopangidwa ndi ROADM + kumpoto-kum'mwera kwa mawonekedwe, ndipo njirayo ikhoza kutsegulidwa, kukonzedwa ndi kubwezeretsedwa mwachisawawa.Zidzakhala zotheka kugwiritsa ntchito zida zosakanikirana zamagetsi za opanga, kapena kugwiritsa ntchito mosakanikirana kwa ma Ethernet olumikizirana ndi mawonekedwe a OTN pamakina omwewo.Panthawiyo, ntchito yogwira ntchito pokhudzana ndi kukulitsa dongosolo ndi kusintha zidzasintha kwambiri, ndipo mawonekedwe a kuwala adzagwiritsidwanso ntchito.Ndikosavuta kusiyanitsa, kasamalidwe ka netiweki kamvekedwe bwino, ndipo mtengo wake udzachepetsedwa kwambiri.
Kwa SDN, maziko apakati ndi kasamalidwe kapakati komanso kugawa kwazinthu zama network.Ndiye, ndi zida zotani zotumizira ma DWDM zomwe zitha kuyendetsedwa pa netiweki yamakono ya DCI?
Pali njira zitatu, njira, ndi ma bandwidths (mafupipafupi).Choncho, kuwala mu mgwirizano wa kuwala + IP kwenikweni ikuchitika mozungulira kasamalidwe ndi kugawa mfundo zitatuzi.
Njira za IP ndi DWDM zimaphwanyidwa, kotero ngati mgwirizano wogwirizana pakati pa IP logical link ndi DWDM channel ikukonzekera kumayambiriro, ndipo mgwirizano wogwirizana pakati pa njira ndi IP uyenera kusinthidwa pambuyo pake, mungagwiritse ntchito OXC. Njirayi imagwiritsidwa ntchito popanga masinthidwe ofulumira pamlingo wa millisecond, zomwe zingapangitse kuti IP wosanjikiza zisadziwe.Kudzera mu kasamalidwe ka OXC, kasamalidwe kapakati pa njira yopatsira patsamba lililonse zitha kuzindikirika, kuti mugwirizane ndi bizinesi ya SDN.
Kusintha kwa njira imodzi ndi IP ndi gawo laling'ono chabe.Ngati mukuganiza zosintha bandwidth mukusintha mayendedwe, mutha kuthana ndi vuto lakusintha zofunikira za bandwidth za mautumiki osiyanasiyana munthawi zosiyanasiyana.Sinthani kwambiri kuchuluka kwa kugwiritsidwa ntchito kwa bandwidth yomangidwa.Chifukwa chake, polumikizana ndi OXC kuti musinthe tchanelo, kuphatikiza ma multiplexer ndi demultiplexer a flexible grid technology, njira imodzi ilibenso utali wokhazikika wapakati, koma imalola kuphimba ma frequency osiyanasiyana, kuti ikwaniritse kusintha kosinthika. kukula kwa bandwidth.Komanso, pankhani yogwiritsa ntchito mautumiki angapo pamaneti topology, kuchuluka kwa ma frequency ogwiritsira ntchito dongosolo la DWDM kumatha kupititsidwa patsogolo, ndipo zida zomwe zilipo zitha kugwiritsidwa ntchito pakudzaza.
Ndi mphamvu zoyendetsera zoyambira ziwiri zoyambirira, kasamalidwe ka njira zotumizira mauthenga kungathandize kuti topology yonse ya netiweki ikhale yokhazikika.Malinga ndi mawonekedwe a netiweki yopatsirana, njira iliyonse ili ndi zida zodziyimira pawokha, kotero ndikofunikira kwambiri kuyang'anira ndikugawa njira panjira iliyonse yopatsirana mwanjira yolumikizana, yomwe ipereka njira yabwino yosankha mautumiki amitundu yambiri , ndi kukulitsa kugwiritsa ntchito zida zamakina panjira zonse.Monga ku ASON, golidi, siliva ndi mkuwa zimasiyanitsidwa ndi mautumiki osiyanasiyana kuti zitsimikizire kukhazikika kwa ntchito zapamwamba kwambiri.
Mwachitsanzo, pali maukonde a mphete omwe ali ndi malo atatu a data A, B, ndi C. Pali ntchito ya S1 (monga intranet data data service), kuchokera ku A mpaka B mpaka C, yokhala ndi mafunde 1 ~ 5 a network ya mphete iyi, funde lililonse lili ndi 100G bandwidth, ndipo nthawi yafupipafupi ndi 50GHz;pali utumiki S2 (utumiki wakunja wapaintaneti), Kuyambira A mpaka B mpaka C, mafunde 6 ~ 9 a netiweki iyi ya mphete amakhala, mafunde aliwonse amakhala ndi bandwidth ya 100G, ndipo nthawi yafupipafupi ndi 50GHz.
Munthawi yanthawi zonse, mtundu uwu wa bandwidth ndi kugwiritsa ntchito njira zimatha kukwaniritsa zofunikira, koma nthawi zina, mwachitsanzo, malo atsopano a data akuwonjezeredwa, ndipo bizinesi imayenera kusamuka pakanthawi kochepa, ndiye kufunika kwa bandwidth ya intranet mu nthawi iyi idzakhala Yawirikiza kawiri, choyambirira 500G bandwidth (5 100G), tsopano ikufunika 2T bandwidth.Ndiye mayendedwe omwe ali pamlingo wopatsira amatha kuwerengedwanso, ndipo njira zisanu za 400G zimayikidwa mu gawo la mafunde.Nthawi yafupipafupi ya njira iliyonse ya 400G imasinthidwa kuchoka pa 50GHz yoyambirira kupita ku 75GHz.Ndi flexible grating ROADM ndi multiplexer/demultiplexer, njira yonse yomwe ili pamtunda wotumizira, kotero njira zisanuzi zimakhala ndi 375GHz spectrum resources.Pambuyo pazithandizo zomwe zili pamlingo wotumizira zakonzeka, sinthani OXC kudzera pagawo loyang'anira pakati, ndikusintha njira zotumizira zomwe zimagwiritsidwa ntchito ndi mafunde apachiyambi a 1-5 azizindikiro zautumiki wa 100G kupita ku 5 yokonzedwa kumene ndikuchedwa kwa millisecond Service 400G. njira imakwera, kotero kuti ntchito yosinthika yosinthika ya bandwidth ndi njira molingana ndi zofunikira zautumiki wa DCI imatsirizidwa, yomwe ingathe kuchitika mu nthawi yeniyeni.Zoonadi, ogwirizanitsa maukonde a zipangizo za IP amafunika kuthandizira 100G / 400G mlingo wosinthika ndi optical signal frequency (wavelength) kusintha ntchito, zomwe sizidzakhala vuto.
Ponena za ukadaulo wapaintaneti wa DCI, ntchito yomwe imatha kumalizidwa ndikutumiza ndi yotsika kwambiri.Kuti mukwaniritse netiweki yanzeru ya DCI, iyenera kuzindikirika pamodzi ndi IP.Mwachitsanzo, gwiritsani ntchito MP-BGP EVPN+VXLAN pa intranet ya IP ya DCI kuti mutumize mwachangu netiweki ya 2 pa ma DCs, yomwe ingakhale yogwirizana kwambiri ndi zida zomwe zilipo kale ndikukwaniritsa zofunikira zamakina a lendi kuti aziyenda momasuka kudutsa ma DC.;Gwiritsani ntchito magawo agawo pamaneti akunja a IP a DCI kuti mukonzekere njira zamagalimoto potengera kusiyana kwa bizinesi, kukwaniritsa zofunikira pakuwonera magalimoto apakati pa DC, kubwezeretsanso njira mwachangu, komanso kugwiritsa ntchito bandwidth yayikulu;maukonde opatsirana oyambira amagwirizana ndi ma OXC amitundu yambiri, Poyerekeza ndi ROADM wamba, imatha kuzindikira ntchito yokonza njira yoyendetsera bwino;kugwiritsa ntchito ukadaulo wosagwiritsa ntchito magetsi wotembenuza wavelength kumatha kuthetsa vuto la kugawikana kwazinthu zamakanema.Kuphatikizika kwa zida zapamwamba komanso zotsika pakuwongolera bizinesi ndi kutumizidwa, kutumiza kosinthika, komanso kugwiritsa ntchito bwino zinthu kudzakhala njira yosapeŵeka m'tsogolomu.Pakalipano, makampani ena akuluakulu apakhomo akuyang'anitsitsa derali, ndipo makampani ena apadera oyambitsa kale akupanga kafukufuku ndi chitukuko cha zinthu zokhudzana ndi luso.Ndikuyembekeza kuwona mayankho okhudzana ndi msika chaka chino.Mwina posachedwapa, OTN idzasowanso m'magulu onyamula katundu, ndikusiya DWDM yokha.
