dci yog.

Txhawm rau ua kom tau raws li cov kev xav tau ntawm cov lag luam rau ntau qhov kev pabcuam kev pabcuam thiab cov neeg siv rau kev ua haujlwm zoo hauv kev sib txuas lus thoob plaws thaj chaw, cov chaw khaws ntaub ntawv tsis yog "cov kob" lawm;lawv yuav tsum muaj kev sib txuas los sib qhia lossis thaub qab cov ntaub ntawv thiab ua tiav cov khoom sib npaug.Raws li cov ntaub ntawv tshawb fawb txog kev lag luam, lub ntiaj teb cov ntaub ntawv chaw sib cuam tshuam kev lag luam yuav tsum loj hlob mus rau 7.65 billion US las hauv 2026, nrog kev loj hlob txhua xyoo ntawm 14% los ntawm 2021 txog 2026, thiab cov ntaub ntawv chaw sib cuam tshuam tau dhau los ua ib qho qauv.

Qhov thib ob, dab tsi yog data center interconnection

Data Center Interconnect (DCI) yog lub network daws teeb meem uas ua rau cov chaw hla cov ntaub ntawv sib txuas lus.Nws nta kev sib txuas tau yooj yim, kev ua haujlwm siab, kev ruaj ntseg, thiab kev ua haujlwm yooj yim thiab kev saib xyuas (O&M), ua tau raws li qhov yuav tsum tau muaj rau kev sib pauv ntaub ntawv zoo thiab kev puas tsuaj rov qab ntawm cov chaw zov me nyuam.

Data center interconnection tuaj yeem raug cais raws li cov ntaub ntawv chaw sib kis deb thiab txoj kev sib txuas hauv network:

Raws li qhov kis tau tus mob:

1) Kev ncua deb: nyob rau hauv 5 km, dav dav siv cabling kom paub txog kev sib tshuam ntawm cov ntaub ntawv chaw hauv lub tiaj ua si;

2) Qhov nruab nrab deb: nyob rau hauv 80 km, feem ntau yog hais txog kev siv cov khoom siv kho qhov muag hauv cov nroog uas nyob ib sab lossis thaj chaw nruab nrab ntawm thaj chaw kom ua tiav kev sib txuas;

3) Kev ncua deb: ntau txhiab mais, feem ntau yog hais txog cov khoom siv kho qhov muag kom ua tiav cov ntaub ntawv txuas mus ntev, xws li submarine cable network;

Raws li txoj kev sib txuas:

1) Network txheej peb kev sib txuas: lub hauv ntej-kawg network ntawm cov chaw sib txawv nkag mus rau txhua qhov chaw hauv cov ntaub ntawv los ntawm IP network, thaum cov ntaub ntawv tseem ceeb ntawm qhov chaw tsis ua haujlwm, cov ntaub ntawv uas tau muab theej rau hauv qhov chaw tos txais tuaj yeem rov qab tau, thiab daim ntawv thov tuaj yeem rov pib dua nyob rau hauv lub qhov rai cuam tshuam luv luv, nws yog ib qho tseem ceeb los tiv thaiv cov tsheb khiav los ntawm kev ua phem hauv network thiab ib txwm muaj;

2) Layer 2 network interconnection: Tsim kom muaj txheej txheej loj 2 network (VLAN) ntawm cov chaw sib txawv cov ntaub ntawv feem ntau ua tau raws li qhov yuav tsum tau muaj ntawm kev hloov pauv hloov pauv ntawm cov neeg rau zaub mov.Cov hauv qab no yuav tsum tau xav txog:

Tsis tshua muaj latency: Txheej 2 kev sib txuas ntawm cov chaw zov me nyuam yog siv los siv cov chaw taws teeb VM teem caij thiab cov ntawv thov cov chaw taws teeb.Txhawm rau ua tiav qhov no, cov kev cai latency rau kev nkag mus rau tej thaj chaw deb ntawm VMS thiab pawg cia yuav tsum tau ua tiav

High bandwidth: Ib qho ntawm cov kev cai tseem ceeb ntawm cov ntaub ntawv chaw sib cuam tshuam yog kom ntseeg tau tias VM tsiv teb tsaws chaw nyob hauv cov chaw khaws ntaub ntawv, uas tso cov kev xav tau siab dua ntawm bandwidth

Muaj Muaj Peev Xwm: Ib txoj hauv kev zoo tshaj plaws los txhim kho kev muaj yog los tsim cov ntawv txuas txuas ntxiv los txhawb kev lag luam txuas ntxiv

3) Kev sib txuas ntawm cov ntaub ntawv khaws cia: Cov ntaub ntawv rov ua dua ntawm thawj qhov chaw thiab qhov chaw rov qab los ntawm kev puas tsuaj yog pom tau los ntawm kev siv thev naus laus zis (pob tshab fiber ntau, DWDM, SDH, thiab lwm yam).

Thib peb, yuav ua li cas kom ua tiav cov ntaub ntawv chaw sib cuam tshuam

1) MPLS thev naus laus zis: Cov txheej txheem kev sib txuas ua ke raws li MPLS thev naus laus zis xav kom cov kev sib txuas sib txuas ntawm cov chaw zov me nyuam cov ntaub ntawv yog lub hauv paus tseem ceeb rau kev siv MPLS thev naus laus zis, kom cov txheej txheem ncaj qha 2 kev sib tshuam ntawm cov chaw zov me nyuam tuaj yeem ua tiav ncaj qha los ntawm VLL thiab VPLS.MPLS suav nrog Txheej 2 VPN thev naus laus zis thiab Txheej 3 VPN thev naus laus zis.VPLS raws tu qauv yog Txheej 2 VPN tshuab.Nws qhov zoo dua yog tias nws tuaj yeem siv tau yooj yim rau kev xa tawm ntawm metro / dav cheeb tsam network, thiab nws tau xa mus rau ntau qhov kev lag luam.

2) IP qhov thev naus laus zis: Nws yog pob ntawv encapsulation thev naus laus zis, uas tuaj yeem paub txog txheej txheej txheej txheej txheej txheej txheej 2 kev sib txuas ntawm ntau lub chaw cov ntaub ntawv;

3) VXLAN-DCI qhov thev naus laus zis: Siv VXLAN thev naus laus zis, nws tuaj yeem paub Layer 2 / Layer 3 interconnection ntawm ntau cov ntaub ntawv chaw network.Raws li kev paub txog technology tam sim no thiab kev paub txog kev lag luam, VXLAN network yog hloov tau thiab tswj tau, kev sib cais ruaj ntseg, thiab kev tswj hwm hauv nruab nrab thiab kev tswj hwm, uas tsim nyog rau yav tom ntej scenario ntawm ntau cov ntaub ntawv chaw sib cuam tshuam.

4. Data center interconnection solution nta thiab cov khoom pom zoo

Scheme nta:

1) Kev sib txuas tau yooj yim: Kev sib txuas yooj yim sib txuas, txhim kho kev sib txuas yooj yim thiab kev ua kom muaj zog, kom tau raws li kev siv Is Taws Nem, faib cov ntaub ntawv xa tawm, hybrid cloud networking thiab lwm yam yooj yim nthuav dav ntawm ntau lub chaw cov ntaub ntawv;

2) Kev ruaj ntseg zoo: DCI thev naus laus zis pab txhim kho cov ntaub ntawv hla cov chaw ua haujlwm, sib koom cov peev txheej ntawm lub cev thiab virtual thoob plaws cheeb tsam kom ua kom zoo dua cov ntaub ntawv ua haujlwm, thiab xyuas kom muaj txiaj ntsig zoo ntawm kev sib txuas hauv network ntawm servers;Nyob rau tib lub sijhawm, los ntawm kev nkag siab zoo encryption thiab kev tswj xyuas nruj, kev ruaj ntseg ntawm cov ntaub ntawv rhiab xws li kev lag luam nyiaj txiag thiab cov ntaub ntawv tus kheej tau lees paub los ua kom muaj kev lag luam txuas ntxiv;

4) Ua kom yooj yim rau kev khiav lag luam thiab kev saib xyuas: Kho cov kev pabcuam network raws li kev xav tau ntawm kev lag luam, thiab ua tiav lub hom phiaj ntawm kev ua haujlwm yooj yim thiab kev saib xyuas los ntawm software txhais / qhib network.

HUA6800 – 6.4T DCI WDM kis tau tus mob platform

HUA6800 yog ib qho khoom siv tshiab DCI kis tau tus mob.HUA6800 muaj cov yam ntxwv ntawm qhov me me, qhov muaj peev xwm loj tshaj plaws, kev sib kis ntev ntev, kev ua haujlwm yooj yim thiab yooj yim thiab kev tswj xyuas, kev ua haujlwm nyab xeeb, txuag hluav taws xob thiab txo qis emission.Nws tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov ntev-ntev, loj-bandwidth Yuav tsum muaj rau kev sib tshuam thiab kev sib kis ntawm cov neeg siv cov ntaub ntawv chaw.

Lub HUA6800 txais yuav tus qauv tsim, uas tsis yog tsuas yog txhawb nqa photoelectric decoupling kom txo cov nqi, tab sis kuj txhawb kev tswj kev sib koom ua ke ntawm photoelectricity hauv tib lub thav duab.Nrog SDN muaj nuj nqi, nws tsim ib qho kev txawj ntse thiab qhib network architecture rau cov neeg siv, txhawb YANG qauv interface raws li NetConf raws tu qauv, thiab txhawb ntau yam kev tswj xws li Web, CLI, thiab SNMP, thiab txhawb kev khiav hauj lwm thiab kev saib xyuas.Nws yog qhov tsim nyog rau cov tes hauj lwm tseem ceeb xws li cov pob txha hauv teb chaws, cov pob txha hauv lub xeev, thiab cov pob txha hauv nroog loj, thiab cov ntaub ntawv chaw sib txuas, ua tau raws li qhov xav tau ntawm cov peev txheej loj tshaj 16T.Nws yog tus nqi sib kis tau zoo tshaj plaws hauv kev lag luam.Nws yog ib qho kev daws teeb meem sib txuas rau IDC thiab cov neeg siv Is Taws Nem los tsim cov chaw muaj peev xwm loj.
