Kana varidzi venzvimbo yedata vachivaka cross-data center network network, ivo vanonyanya kufunga nyaya dzakadai sehombe bandwidth, low latency, high density, kukurumidza kuendesa, nyore kushanda uye kugadzirisa, uye kuvimbika kwakanyanya.Parizvino, iyo mainstream hombe-bandwidth OTN tekinoroji inonyanya kudzorwa neakawanda mahombe-akakura emagetsi ekugadzira zvigadzirwa zvefoni (machipisi anokurukurwa zvakasiyana), seHuawei, ZTE, uye Aran.Vatengi vakuru vavanosangana navo ndevechinyakare telecom operators, saka zvigadzirwa zveOTN zvinonyanya kugadzirwa kuti zvisangane nehunhu hwesevhisi yevashandi ava.Nekuda kweizvi, OTN iri kuwedzera kushandiswa muDCI network application muindasitiri yeInternet.Matambudziko mazhinji ekusawirirana.
Hunhu hwemichina yeOTN ndiwo matambudziko akafanana akasangana neDCI, bhizinesi rakapfuma pamusoro, simba reOAM retiweki, kuronga uye kuwedzeredza kugona kweakasiyana granular bandwidths, mutsara kukanganisa kushivirira pasi pemamiriro ekureba, uye kushandiswa kweyakaderera-voltage yakananga. current.Zvimiro zvakaita sekuderera kwekushandisa mwero wesimba rekushandisa kwemidziyo.
1. Kugona kushandisa bhizinesi rakapfuma kunoda kuti vashandi veO&M vawedzere hunyanzvi, kuvimba zvakanyanya nerutsigiro rwehunyanzvi kubva kuvagadziri, uye kuve nehunyanzvi hwakavharika.
2. Simba reOAM rine simba, zvisingaenderani zviyero, zvakanyanya kuoma uye zvakanyanya kuzvimiririra kuwirirana ne-cross-network, uye mabasa asina maturo anounzawo mari yakawanda yekufambisa uye kushanda kune network yeDCI.
3. Yakasiyana granule kuronga kugona kunoita sevhisi encapsulation furemu chimiro ive yakaoma uye yakawanda nested bytes.
4. Mutsara wakareba-refu kukanganisa kukanganisa kunoita kuti FEC algorithm yakaoma, inodya zvakanyanya pamusoro uye inotora nguva yakareba kuti igadziriswe.
5. Iyo 48V-DC magetsi emagetsi emagetsi eOTN yakasiyana neyakajairwa 19-inch 220V-AD (kana 240V-DC) makabati anoshandiswa munzvimbo dzakawanda dze data.Iko kuiswa kwakaoma uye kunoda shanduko yemagetsi muimba yekombuta
6. Zvigadzirwa zveOTN zvechinyakare zvine furemu yakakura, iyo isingakodzeri kuisirwa mumakabati akajairwa, uye huwandu hwesimba hahuna kukwirira.Gare gare kuwedzera kunonetsa uye kunoda kuti makabati afambiswe kana kuvakwa patsva.
Parizvino, yedu DCI network inonyanya kupa mapaipi ekuyambuka-data data data.Hunhu hunokosha hwemuenzaniso webhizimisi ndeiyi: yakabatana uye imwe chete bandwidth granularity zvinodiwa, bandwidth yakakura, cross-data center services (kunyanya multi-active IDC, makuru data services) ) ine zvishoma latency zvinodiwa uye zvinodiwa zvakanyanya pakugadzikana kwemambure;panguva imwecheteyo, nekuda kwekushaikwa kwevashandi vakakodzera uye vehunyanzvi muindasitiri yeInternet, kushanda uye kuchengetedza network yeDCI inoda kuve "yakapusa" "yakapusa" uye "yakapusa" - zvinhu zvakakosha zvinotaurwa katatu (apo Isn Handiti imhando yetiweki?);kuputika kweInternet kunoita kuti kuvaka uye kuwedzera kutenderera kupfupi kupfupi (vashandisi 'OTN yekuwedzera kutenderera kazhinji hafu yegore kusvika kune rimwe gore, nepo iyo Internet yega DCI yekuwedzera zvinodiwa ndeye 1 kusvika 3 mwedzi), Naizvozvo, zvakakosha kumanikidza. nguva muzvikamu zvose.
Naizvozvo, OTN inopa mhinduro inoshandisika yeDCI, asi OTN haisiriyo mhinduro yakakodzera kuDCI.Zvino sezvo network yeDCI iri kuwedzera, pane kudiwa kuri kuwedzera kwemhinduro dzakakodzera dzekugadzirisa matambudziko kubva pamutengo kusvika pakuvaka, kushanda uye kugadzirisa.matambudziko akasiyana-siyana akasangana nawo.Uye matambudziko aya haasi chinhu kunze kwezvitanhatu zvinodiwa zveDCI network (yakakura bandwidth, low latency, high density, kukurumidza kutumirwa, kushanda nyore uye kugadzirisa, uye kuvimbika kwakanyanya):
1. Yakakura bandwidth, DCI transmission network haina mhando dzakapfuma dzegranules sevashandi, bandwidth granules yeDCI transmission network iri nyore, ikozvino inowanzoshandiswa 10G kana 100G, mune ramangwana 200G / 400G, nezvimwewo, saka hapana chikonzero. kuti uzviite nehukuru bandwidth Bandwidth pane mamwe granularities.Nekuda kwekuti kureba kweiyo DCI transmission network kazhinji haina kurebesa, uchishandisa iyo 400G sisitimu yakavakirwa pa200G PM-16QAM dual-carrier modulation, nhambwe yekufambisa isina relay yemagetsi inogona kuita makiromita mazana mashanu (PM-64QAM iri. anenge 200 makiromita) , kuitira kuti metro backbone transmission yeDCI irege kuganhurirwa nechinhambwe.
2. Low latency, DCI bhizinesi zvinodiwa, kunyanya kana cloud computing inoshandiswa kuvhara zviwanikwa uye akawanda-anoshanda data centers, iyo latency inotarirwa pa microsecond level, saka nguva yekufambisa data inofanira kuva shoma sezvinobvira, ichishuva kudarika kumhanya kwechiedza.Bvisa basa risingakoshi rekugadzirisa data uye kuderedza nzira dzekutumira masaini.Semuenzaniso, nekubvisa iyo SD-FEC basa rinoshandiswa ne100G OTN, imwe chete-kumashure-kumashure inogona kuchengetedza 200 microseconds, uye kubvisa iyo cross-level OTN encapsulation inogona kuchengetedza makumi emamicroseconds, uye zvine musoro kushandisa hubspoke topology yebasa rakakosha. kuve nechokwadi nzira ipfupi.Ehe, inogona zvakare kubatirana neMPLS neQOS padanho reIP kuyedza kuona kuti kunonoka padanho rekutumira data zvakare kuri nani.
3.High density, imwe U, kana 2U, inogona kuwana bandwidth kusvika kuT, DWDM optical layer uye magetsi emagetsi emagetsi ekuparadzanisa, kuvandudza kushandiswa kwehutano hwechigadzirwa, uye kuderedza ukuru hwe optical module.Semuenzaniso, kushandiswa kweQSFP28 optical modules kunogona kuvimbisa kuti 100G yekuwana kukwanisa kwechigadziro chimwe chete inovandudzwa zvikuru, uye kushandiswa kweCFP2 daylighting modules pamutsara wemutsara unogona kuvimbisa kuti bandwidth yekufambisa kwechigadzirwa chose inovandudzwa, 1U inogona. kuva 1.6T, 3.2T.Parizvino, zvigadzirwa zvakawanda zvine hukama zvakaonekwa munyika, senge ADVA, coriant, ciena nemamwe makambani.Ehe, Huawei wepamba akatangisa zvine hukama zvigadzirwa zve902.Zvakadaro, pakupedzwa kwechinyorwa chino, zvinoita sekunge bvunzo yekuwana network yeBazi reIndasitiri neInformation Technology haisati yapera.High density ichakonzera kushandiswa kwesimba guru uye kupisa kupisa.Naizvozvo, nzira yepakutanga yeOTN yekubvisa kupisa kwemhepo yekuruboshwe nekurudyi mukati nekunze, uye kumusoro nekudzika mhepo mukati nekubuda inofanira kuraswa.
Device kutonhora zvinodiwa.
4. Kukurumidza kutumira, uchishandisa yazvino yakajairwa IDC 19-inch rack, yakafanana nechimiro chesevha huru, uchishandisa AC-220V yemagetsi yakananga, kubvisa kudiwa kwesimba neshanduko yekabati, uye kuona kuti zvinhu zvinogona kuiswa. masherufu pakarepo mushure mekunge vasvika mukamuri yekombuta, uye anogona kugadzirwa mushure mekubaya mumagetsi.bhizinesi, uye ita basa rakanaka mubasa rakamisikidzwa rekugamuchira kuti uwane kukurumidza kutumirwa.
5. Kushanda nyore uye kugadzirisa, DCI bhizinesi modhi zvinodiwa, chinhambwe chepakati pe data data hachizove kure, uye yakaoma manejimendi pamusoro, OAM uye mamwe mabasa haafanirwe kuita basa rakakura muchiitiko ichi, uye kugadzirisa kwakaoma kunoderedzwa zvakare. Inovandudza kufambiswa kwedata, inovandudza nguva yekugadzirisa data, uye ine zvinodiwa zvepamusoro zvetekinoroji uye yakavharwa zvakanyanya.Kubatanidza masaini zvakananga kuburikidza neEthernet kunobvisa iyo yakaoma pamusoro peOTN, saka yechinyakare IP network mainjiniya anogona kushanda uye kuchengetedza iyo DCI system.Mushure mekubatanidza nzvimbo itsva dzekuchamhembe dzakaita seYANG modhi, REST API, uye netconf, DCI kutapurirana michina manejimendi uye IP network yemidziyo manejimendi inogadzirwa neiyo yakafanana interface, kuitira kuti iite zvirinani kuita yakabatana-yakavakirwa centralized network manejimendi.
6. Kuvimbika kwepamusoro, kutenderera kwemaitiro akawanda uye tekinoroji yekudzivirira iyo isingazivi pamusoro pepamusoro icharamba ichiita basa muDCI transmission network.Kutadza padanho repazasi rekubatanidza hakufanire kuve nemhedzisiro pamasevhisi kunze kwekunge avhiringwa zvachose.Maonero kana kukanganisa, kungave kuri kudzivirira switching, link jitter, kunonoka kuwedzera, nezvimwe.
