Qhov no tso cai rau BGP txoj kev sib pauv nrog lub nraub qaum yam tsis tas yuav tsum muaj cov khoom siv sib cais.
Intent-Driven Networks: networks uas txheeb xyuas kev xav
Huawei Intent-Driven Network (IDN) tswvyim rov qab rau xyoo 2018. Txij thaum ntawd los, lub tuam txhab tau txuas ntxiv ua haujlwm ntawm cov tes hauj lwm uas siv cov cuab yeej siv huab cua, cov ntaub ntawv loj thiab kev txawj ntse txawj ntse los txheeb xyuas cov hom phiaj thiab kev xav ntawm cov neeg siv.
Qhov tseem ceeb, peb tab tom tham txog kev txav los ntawm automation mus rau autonomy. Tus neeg siv lub hom phiaj qhia tau rov qab los ntawm cov lus pom zoo los ntawm cov khoom lag luam network txog kev siv lub hom phiaj no. Lub hauv paus ntawm qhov kev ua haujlwm no yog Agile Controller-DCN peev xwm uas yuav muab ntxiv rau cov khoom lag luam kom ntseeg tau tias kev ua raws li IDN lub tswv yim.
Nyob rau hauv lub neej yav tom ntej, nrog rau kev qhia ntawm IDN, nws yuav muaj peev xwm mus xa cov kev pab cuam network nyob rau hauv ib tug nias, uas implies lub siab tshaj plaws degree ntawm automation. Cov qauv tsim qauv ntawm kev ua haujlwm hauv network thiab kev muaj peev xwm los ua ke cov haujlwm no yuav tso cai rau tus thawj coj tsuas yog qhia cov kev pabcuam uas yuav tsum tau ua kom muaj nyob rau ntawm ntu ntu.
Txhawm rau ua tiav qib ntawm kev tswj hwm no, ZTP (Zero Touch Provisioning) txheej txheem tseem ceeb heev. Huawei tau ua tiav qhov kev vam meej loj hauv qhov no, ua tsaug uas nws muaj peev xwm ua kom tag nrho xa tawm lub network tawm ntawm lub thawv.
Cov txheej txheem txuas ntxiv thiab xa tawm yuav tsum suav nrog cov txheej txheem rau kev tshuaj xyuas kev sib txuas ntawm cov peev txheej (kev sib txuas hauv network) thiab ntsuas kev hloov pauv hauv kev ua haujlwm hauv network nyob ntawm nws cov qauv kev ua haujlwm. Cov theem no suav nrog kev simulation ua ntej pib ua haujlwm tiag tiag.
Cov kauj ruam tom ntej yog teeb tsa cov kev pabcuam kom haum rau cov neeg siv khoom xav tau (kev pabcuam) thiab lawv cov ntawv pov thawj, ua los ntawm cov cuab yeej tsim hauv Huawei. Tom qab ntawd txhua yam uas tseem tshuav yog txhawm rau txheeb xyuas qhov tshwm sim.
Tam sim no nws muaj peev xwm mus hla tag nrho txoj kev piav qhia uas siv ib qho kev qhia dav dav raws li iMaster NCE platform uas muaj Agile Controller-DCN thiab eSight network element Management system (EMS).
Tam sim no, Agile Controller-DCN tuaj yeem tshawb xyuas qhov muaj peev xwm thiab muaj kev sib txuas, nrog rau kev ua haujlwm zoo (tom qab kev pom zoo los ntawm tus thawj tswj hwm) teb cov teeb meem hauv lub network. Ntxiv cov kev pabcuam tsim nyog tam sim no ua tiav manually, tab sis yav tom ntej Huawei npaj siab yuav ua haujlwm rau qhov no thiab lwm yam haujlwm, xws li kev xa tawm neeg rau zaub mov, kev teeb tsa network rau cov tshuab khaws cia, thiab lwm yam.
Service chains thiab micro-segmentation
Agile Controller-DCN muaj peev xwm ua cov kev pabcuam headers (Net Service Headers, lossis NSH) muaj nyob rau hauv cov pob ntawv VXLAN. Qhov no muaj txiaj ntsig zoo rau kev tsim cov kev pabcuam pabcuam. Piv txwv li, koj npaj siab yuav xa ib yam ntawm cov pob ntawv raws li txoj kev uas txawv ntawm qhov muab los ntawm tus txheej txheem routing raws tu qauv. Ua ntej lawv tawm hauv lub network, lawv yuav tsum mus dhau qee yam khoom siv (firewall, thiab lwm yam). Txhawm rau ua qhov no, nws yog qhov txaus los teeb tsa cov kev pabcuam uas muaj cov cai tsim nyog. Ua tsaug rau cov txheej txheem zoo li no, nws muaj peev xwm, piv txwv li, txhawm rau txhim kho kev ruaj ntseg cov cai, tab sis lwm qhov chaw ntawm nws daim ntawv thov kuj ua tau.
Daim duab qhia tau meej meej txog kev ua haujlwm ntawm RFC-tshaj cov kev pabcuam raws li NSH, thiab tseem muab cov npe ntawm cov khoom siv hloov kho uas txhawb nqa lawv.
Huawei cov kev pabcuam chaining muaj peev xwm ua tiav los ntawm micro-segmentation, cov txheej txheem kev ruaj ntseg network uas cais cov ntu kev ruaj ntseg mus rau ib tus neeg ua haujlwm. Txhawm rau zam qhov yuav tsum tau teeb tsa tus lej loj ntawm ACLs pab tau nyob ib puag ncig Access Control List (ACL) lub tog raj kheej.
Kev ua haujlwm ntse
Tsiv mus rau qhov teeb meem ntawm kev lag luam network, ib tus tsis tuaj yeem hais txog lwm yam khoom ntawm iMaster NCE kaus hom - FabricInsight ntse network analyzer. Nws muab ntau lub peev xwm los sau cov telemetry thiab cov ntaub ntawv hais txog cov ntaub ntawv ntws hauv lub network. Telemetry yog sau los ntawm gRPC thiab sau cov ntaub ntawv ntawm cov ntawv xa tawm, tsis pub dhau thiab ploj pob ntawv. Qhov thib ob loj ntawm cov ntaub ntawv yog sib sau ua ke siv ERSPAN (Encapsulated Remote Switch Port Analyzer) thiab muab lub tswv yim ntawm cov ntaub ntawv ntws hauv cov ntaub ntawv chaw. Qhov tseem ceeb, peb tab tom tham txog kev sau TCP headers thiab tus nqi ntawm cov ntaub ntawv xa mus rau txhua lub sijhawm TCP. Qhov no tuaj yeem ua tiav siv ntau yam khoom siv Huawei - lawv cov npe tau nthuav tawm hauv daim duab.
SNMP thiab NetStream tseem tsis tau hnov qab, yog li Huawei tau siv ob qho tib si qub thiab tshiab mechanisms txhawm rau txav los ntawm lub network li "black box" mus rau lub network uas peb paub txhua yam hais txog.
AI Npuag: Lossless Smart Grid
AI Fabric nta txhawb nqa los ntawm peb cov khoom siv kho vajtse yog tsim los hloov Ethernet rau hauv kev ua haujlwm siab, qis-latency, tsis muaj pob ntawv poob. Qhov no yog qhov tsim nyog los siv cov txheej txheem kev xa tawm yooj yim hauv cov ntaub ntawv chaw network.
