OLTCov khoom siv muaj ob lub ntsiab lus hauv qab no: thawj, kev txhawb nqa rau 10G PON board daim npav, suav nrog kev nce ntawm ib qho kev sib pauv peev thiab tag nrho cov peev txheej pauv, thiab qhov chaw nres nkoj uplink txhawb rau cov chaw nres nkoj loj dua xws li 10GE, thiab lwm yam; Thib ob, nrog tag nrho cov qauv network ntawm txhua tus neeg teb xov tooj hloov mus rau SDN / NFV,,OLTkhoom siv nws tus kheej ntsib teeb meem ntawm kev hloov mus rau SDN / NFV.
(1) Kev them nyiaj yug rau 10 GPON rau cov khoom siv network tam sim no
Cov khoom siv ntawm lub network tam sim no tuaj yeem txhawb nqa 10G PON board daim npav los ntawm kev kho dua tshiab ntawm daim npav tswj hwm lub ntsiab thiab cov khoom siv hluav taws xob. Tom qab kho dua tshiab, cov khoom siv uas twb muaj lawm feem ntau kuj txhawb 10G PON. Yog li ntawd, thaum lub sij hawmOLTcov khoom siv tau teeb tsa nrog 10G PON board, ntxiv rau kev txhawb nqa ntawm cov khoom siv nws tus kheej, txhua tus tub lag luam kuj yuav tsum tau txhim kho cov kev tswj hwm network thiab cov khoom siv.
(2) Kev hloov pauv mus rau SDN / NFV
SDN / NFV tuaj yeem faib cov peev txheej nkag, pab tswj kev pabcuam, thiab paub txog kev nqa ntau yam kev pabcuam. Los ntawm SDN / NFV, cov haujlwm hauv qab no tuaj yeem pom tau: cov khoom siv kho vajtse ywj pheej, VLAN cov peev txheej, MAC rooj, rooj sib tham, QoS cov khoom siv ywj pheej; software nta ywj siab, thiab cov yam ntxwv tuaj yeem teeb tsa sib txawv thiab sib txawv customization; tswj decentralization domain, configuration pipeline rho tawm ntawm vOLT, nrog rau kev pab cuam,, kev khiav hauj lwm thiab txij nkawm, tswb, cav, thiab lwm yam.
OLTpab kiag li lawm raws li kev nkag tau mus rau SDN / NFV, lub ntsiab saib yog hais tias nws yog ib qho nyuaj rau ua tiav "dawb lub thawv", feem ntau kom paub txog network-theem kev tswj thiab nce mus txog ntawm ib co kev tswj uas tsis yog-lub sij hawm. Nyob rau hauv thawj theem, tus sau feem ntau paub txog network slicing, namelyOLTvirtualization, ib qho virtualOLThauv ntau OLTs. Tam sim no, nws tuaj yeem pom tau los faib virtualizationOLTRaws li daim npav board, PON chaw nres nkoj, lub davhlau ya nyob twg thiab cov neeg siv chaw nres nkoj (UNI). Nyob rau theem tom ntej, tus qauv sab qaum teb-sab qab teb interface (Netconf / YAGN, OpenFlow) tau maj mam paub, thiab kev tswj hwm thiab kev xa tawm raug cais los ntawm SDN maub los.
Cov xwm txheej tseem ceeb ntawm SDN / NFV yog lub nroog nyab xeeb (kev soj ntsuam video), PON nqa cov kev pabcuam LSN, lub tsev kawm ntawv network, chaw nres tsheb me me rov qab, tsev so txawv teb chaws, thiab lwm yam.
(3) Lwm tiamOLTcov khoom
Tam sim no, tiam tom ntej kho qhov muag nkag platform feem ntau yog raws li cov khoom uas twb muaj lawm kom paub txog kev hloov mus rau tiam tom ntej 100G nkag thiab SDN, thiab kev hloov pauv ntawmOLTcov khoom siv rau hauv SDN yog qhov tseem ceeb tseem nyob rau theem kev npaj, yog liOLTtsis muaj cov xwm txheej rau SDN nyob rau lub sijhawm luv.
Saum toj no yog tus qauv ntawm txoj kev loj hlob ntawmOLTkhoom, Shenzhen HDV photoelectron technology co., LTD.is muaj zog, cov khoom kub tseem ceeb nrogOLTkhoom siv: khib homolt ua, me meolt ua, compactolt ua, olt uahloov, olt uamodule, kev sib txuas lusolt ua, thiab lwm yam, kev loj hlob ntawmOLTcov khoom siv yog ntsuas tsis tau nyob rau hauv lub era ntawm network,OLTkuj yog ib qho ntawm cov khoom siv sib txuas lus tseem ceeb hauv cov khoom siv network, yog tias tsim nyog, koj tuaj yeem kawm los ntawm peb lub tuam txhab, peb yuav muab kev tshaj lij ua ntej muag thiab kev pab cuam tom qab muag.
