chii chinonzi dci.

Kusangana nezvinodiwa zvemabhizinesi erutsigiro rwe-multi-service uye vashandisi vemhando yepamusoro network zviitiko munzvimbo dzese, nzvimbo dze data hadzisisiri "zvitsuwa";ivo vanofanirwa kubatanidzwa kuti vagovane kana kutsigira data uye kuwana kuyera kuyera.Sekureva kwemushumo wekutsvagisa musika, musika wepasi rose wedhata yekubatanidza musika unotarisirwa kukura kusvika pamabhiriyoni manomwe neshanu emadhora ekuAmerica muna 7.65, paine huwandu hwekukura kwepagore hwe14% kubva 2021 kusvika 2026, uye data centre yekubatanidza yave tsika.

Chechipiri, chii chinonzi data center interconnection

Data Center Interconnect (DCI) imhinduro yetiweki inoita kuti nzvimbo dzekuyambuka-data dzitaurirane.Iyo inoratidzira inochinjika yekubatanidza, kugona kwakanyanya, chengetedzo, uye kurerutswa mashandiro nekugadzirisa (O&M), kusangana nezvinodiwa zvekuchinjana data kwakanyatso uye kudzoreredza njodzi pakati penzvimbo dzedata.

Data center interconnection inogona kuiswa maererano nedata centre yekufambisa kureba uye network yekubatanidza nzira:

Zvinoenderana nedhiza rekutumira:

1) Chinhambwe chipfupi: mukati me5 km, general cabling inoshandiswa kuona kubatana kwenzvimbo dzedata mupaki;

2) Chinhambwe chepakati: mukati me80 km, kazhinji inoreva kushandiswa kwemamodule optical mumaguta ari padyo kana nzvimbo dzepakati penzvimbo kuti uwane kubatana;

3) Chinhambwe chakareba: zviuru zvemakiromita, kazhinji zvinoreva optical kutapurirana michina kuti iwane kureba kureba data centre yekubatanidza, senge submarine tambo network;

Maererano nzira yekubatanidza:

1) Network layer matatu yekubatanidza: iyo yekumberi-yekupedzisira network yenzvimbo dzakasiyana dzedata inopinda yega yega data data kuburikidza neIP network, kana yekutanga data data saiti ikatadza, iyo data yakakopwa kune yekumira saiti inogona kudzoserwa, uye application. inogona kutangwazve mukati menguva pfupi yekukanganisa hwindo, zvakakosha kuchengetedza iyi traffic kubva kune yakaipa network kurwiswa uye inogara iripo;

2) Layer 2 network yekubatanidza: Kuvaka yakakura Layer 2 network (VLAN) pakati penzvimbo dzakasiyana dze data zvinonyanya kusangana nezvinodiwa zvekutenderera kwekuchinja kwesevha masumbu.Zvinhu zvinotevera zvinofanira kufungwa nezvazvo:

Low latency: Layer 2 yekubatanidza pakati pe data data inoshandiswa kuita kure kure VM kuronga uye cluster kure maapplication.Kuti uite izvi, izvo zvinodikanwa zvekunonoka zvekusvika kure pakati peVMS uye cluster kuchengetedza zvinofanirwa kusangana

Yakakwira bandwidth: Chimwe chezvakakosha zvinodiwa zve data centre yekubatanidza ndeye kuona VM kutama munzvimbo dzese dze data, izvo zvinoisa zvakakwirira zvinodiwa pa bandwidth.

Kuwanikwa Kwepamusoro: Imwe yedzakanakisa nzira dzekuvandudza kuwanikwa ndeye kugadzira backup links kutsigira kuenderera kwebhizinesi.

3) Kuchengetedzwa kwetiweki yekubatanidza: Kudzokororwa kwedata pakati penzvimbo yekutanga nenzvimbo yekudzoreredza njodzi kunoitwa nenzira yekufambisa matekinoroji (bare optical fiber, DWDM, SDH, nezvimwewo).

Chechitatu, maitiro ekuwana data center interconnection

1) MPLS tekinoroji: Iyo yekubatanidza chirongwa yakavakirwa paMPLS tekinoroji inoda kuti iyo yekubatanidza network pakati penzvimbo dzedata ndiyo musimboti wetiweki yekuendesa MPLS tekinoroji, kuitira kuti yakananga layer 2 yekubatanidza yedata data ipedze zvakananga kuburikidza neVLL neVPLS.MPLS inosanganisira Layer 2 VPN tekinoroji uye Layer 3 VPN tekinoroji.VPLS protocol ndiyo Layer 2 VPN tekinoroji.Chakanakira ndechekuti inogona kuita zviri nyore kutumira metro/wide area network, uye inoiswa mumaindasitiri mazhinji.

2) IP tunnel tekinoroji: Iyo packet encapsulation tekinoroji, inogona kuona iyo heterogeneous network layer 2 yekubatanidza pakati peakawanda data nzvimbo;

3) VXLAN-DCI tunnel tekinoroji: Ichishandisa tekinoroji yeVXLAN, inogona kuona Layer 2 / Layer 3 yekubatanidza yeakawanda-data centre network.Kubva pane yazvino tekinoroji kukura uye bhizinesi kesi ruzivo, VXLAN network inochinjika uye inodzoreka, yakachengeteka yekuzviparadzanisa nevamwe, uye yepakati manejimendi uye kutonga, iyo yakakodzera kune ramangwana mamiriro e-multi-data center interconnection.

4. Data center interconnection solution maficha uye mazano echigadzirwa

Scheme features:

1) Flexible interconnection: Flexible interconnection mode, kunatsiridza kushanduka kwetiweki uye scalability, kusangana neInternet kuwana, kugoverwa kutumirwa kwenzvimbo dze data, hybrid cloud networking uye kumwe kuwedzera kuri nyore kushanduka pakati penzvimbo dzakawanda dze data;

2) Kuchengetedzeka kwakasimba: DCI tekinoroji inobatsira kukwirisa mhiri-dhata nzvimbo yekuremerwa, kugovera zviwanikwa zvenyama uye zvechisikigo mumatunhu ese kukwirisa data basa rekuita, uye kuve nechokwadi chekugovera kunobudirira kwetiweki traffic pakati pemaseva;Panguva imwecheteyo, kuburikidza neyakavharidzirwa encryption uye yakasimba yekuwana kutonga, kuchengetedzeka kwe data rakadzama senge kutengeserana kwemari uye ruzivo rwemunhu rwunovimbiswa kuve nechokwadi chekuenderera kwebhizinesi;

4) Rerutsa kushanda nekugadzirisa: Gadzirisa network masevhisi zvinoenderana nezvinodiwa nebhizinesi, uye uwane chinangwa chekurerutsa kushanda nekugadzirisa kuburikidza nesoftware tsananguro / yakavhurika network.

HUA6800 - 6.4T DCI WDM kutapurirana chikuva

Iyo HUA6800 ndeye innovative DCI kutapurirana chigadzirwa.Iyo HUA6800 ine hunhu hwehukuru hudiki, hukuru-hukuru hwekugona sevhisi yekuwana, ultralong-chinhambwe kutapurirana, nyore uye nyore mashandiro uye manejimendi ekugadzirisa, kushanda kwakachengeteka, kuchengetedza simba uye kuderedza emission.Inogona kuzadzisa zvinodikanwa zvekureba-kure, hombe-bandwidth Zvinodiwa zvekubatanidza uye kutapurirana kwevashandisi data centers.

Iyo HUA6800 inotora modular dhizaini, iyo isingangotsigire photoelectric decoupling kuderedza mutengo, asi zvakare inotsigira yakasanganiswa manejimendi yephotoelectricity mune imwechete furemu.Iine SDN basa, inogadzira yakangwara uye yakavhurika network yekuvaka yevashandisi, inotsigira YANG modhi interface yakavakirwa paNetConf protocol, uye inotsigira akasiyana manejimendi akadai seWebhu, CLI, uye SNMP, uye inofambisa mashandiro nekugadzirisa.Inokodzera masevhisi epakati senge nyika backbone network, provincial backbone network, uye metropolitan backbone network, uye data center interconnection, kusangana nezvinodiwa zvehombe-kugona node pamusoro pe16T.Ndiyo inonyanya kudhura-inoshanda kutapurirana chikuva muindasitiri.Iyo yekubatanidza mhinduro yeIDC uye Internet vashandisi kuvaka yakakura-inokwana data nzvimbo.
