Lub network xyuas qhov system occupies ib tug kiag li txoj hauj lwm nyob rau hauv qhov kev ruaj ntseg project. Nyob rau hauv lub high-txhais network video soj ntsuam system, muaj feem ntau phenomena xws li daim duab qeeb thiab freezes. Muaj ntau qhov laj thawj rau cov xwm txheej no, tab sis feem ntau, qhov hloov pauv tsis tsim nyog txaus, ua rau tsis txaus bandwidth. Qhov hloov pauv yog ib qho khoom siv tsis tseem ceeb rau tag nrho lub cev. Txawm hais tias nws tau teeb tsa kom raug lossis tsis ncaj qha cuam tshuam rau kev ruaj ntseg tom qab ntawm lub network saib xyuas qhov system.

Thaum xaiv qhov hloov pauv, koj yuav tsum xaiv los ntawm bandwidth thiab pob ntawv xa mus. Lub backplane bandwidth yog qhov siab tshaj plaws ntawm cov ntaub ntawv uas tuaj yeem ua haujlwm ntawm qhov hloov pauv interface processor lossis daim npav interface thiab cov ntaub ntawv npav. Nws cim tag nrho cov ntaub ntawv sib pauv muaj peev xwm ntawm qhov hloov pauv, qhov siab dua qhov backplane bandwidth, lub peev xwm ua tau zoo dua cov ntaub ntawv. Pob ntawv xa tawm tus nqi kuj tseem hu ua chaw nres nkoj hla, uas yog hais txog lub peev xwm ntawm lub router xa cov ntaub ntawv xa mus rau ntawm qhov chaw nres nkoj. Qhov siab dua cov pob ntawv xa mus, qhov zoo dua.

Nyob rau hauv cov nqe lus ntawm network topology, ib tug nruab nrab thiab loj-txhais network video soj ntsuam system yuav tsum tau txais ib tug peb-txheej network architecture: nkag mus rau txheej, convergence txheej, thiab core txheej.

Yuav xaiv li casaccess txheej hloov?
Cov txheej txheem nkag mus yog feem ntau txuas nrog rau pem hauv ntej-kawg network high-txhais lub koob yees duab thiab txuas nrog kev sib sau ua ke. Raws li 4M code kwj ntawm 1080P network koob yees duab, muaj pes tsawg txoj kev ntawm 1080P network koob yees duab tuaj yeem txuas rau ib qho 100M chaw nres nkoj nkag mus?

Qhov tseeb bandwidth ntawm peb cov keyboards nquag siv yog 50% -70% ntawm tus nqi theoretical, yog li qhov tseeb bandwidth ntawm 100M chaw nres nkoj yog 50M-70M. 4M * 12 = 48M, yog li nws tau pom zoo tias ib qho 100M nkag mus tau tuaj yeem txuas mus rau qhov siab tshaj plaws ntawm 12 1080P network koob yees duab. Nyob rau tib lub sijhawm, txiav txim siab tias tam sim no kev saib xyuas network tau txais kev hloov pauv hloov pauv, tus nqi siab tshaj plaws ntawm lub koob yees duab code kwj yuav dhau 4M bandwidth, thiab bandwidth redundancy tsim kuj raug txiav txim siab. Yog li ntawd, nws yog qhov zoo tshaj plaws thaum lub 100M nkag mus hloov tau tswj nyob rau hauv 8 units, thiab ntau tshaj 8 units raug pom zoo. Gigabit chaw nres nkoj. Nyob rau hauv ib co ultra-high-txhais network saib xyuas systems, thiaj li yuav ua kom paub tseeb cov duab video thiab kev ntseeg siab ntawm cov ntaub ntawv xa mus, cov txheej txheem nkag tau ncaj qha xaiv tag nrho Gigabit keyboards.

Yuav ua li cas xaiv aggregation txheej hloov?

Cov txheej txheej sib sau ua ke feem ntau txuas nrog cov txheej txheem nkag mus thiab cov tub ntxhais hloov pauv ntawm qhov chaw saib xyuas uplink. Qhov kev ua tau zoo yog siab dua li ntawm kev nkag mus. Raws li qhov xwm txheej ib txwm muaj, qhov kev sib sau ua ke yuav tsum xaiv txheej txheej 2 hloov nrog qhov chaw nres nkoj gigabit upload. Lub 100M chaw nres nkoj ntawm qhov hloov pauv txuas nrog qhov hloov pauv, thiab Gigabit chaw nres nkoj txuas nrog cov tub ntxhais hloov ntawm qhov chaw saib xyuas. Tus naj npawb ntawm kev sib txuas ntawm qhov sib txuas sib txuas yuav tsum tau tswj tsis pub dhau 30. Nws tseem suav nrog 4M code kwj ntawm 1080P network koob yees duab. Txhua txheej nkag mus rau ntawm qhov kawg ntawm sab xub ntiag muaj 6 1080P network koob yees duab, thiab cov kev sib txuas sib txuas txuas nrog 5 nkag txheej hloov. Tag nrho cov bandwidth ntawm kev sib sau ua ke yog 4M * 6 * 5 = 120M, yog li qhov chaw nres nkoj cascade ntawm kev sib sau ua ke thiab cov tub ntxhais hloov yuav tsum yog qhov chaw nres nkoj gigabit.

Yuav ua li cas xaiv core hloov?

Cov txheej txheem tseem ceeb yog txuas nrog cov txheej txheej sib sau ua ke, lub uplink saib xyuas qhov chaw saib xyuas video, chaw cia khoom, digital matrix thiab lwm yam khoom siv, uas yog cov tub ntxhais ntawm tag nrho cov ntsiab lus network saib xyuas qhov system.then xaiv cov tub ntxhais hloov, koj yuav tsum xav txog lub peev xwm bandwidth ntawm tag nrho cov kab ke thiab yuav ua li cas teeb tsa cov txheej txheem tseem ceeb hloov tsis raug, uas yuav ua rau qhov kev tshuaj ntsuam video tsis pom zoo.yog li ntawd, lub chaw saib xyuas pom zoo kom xaiv ib tug tag nrho gigabit core hloov. Yog tias muaj ntau lub ntsiab lus, VLANs yuav tsum tau muab faib, thiab peb txheej tag nrho Gigabit core hloov yuav tsum raug xaiv. Kev soj ntsuam loj loj nrog ntau dua 150 lub koob yees duab yuav tsum xav txog peb txheej 10 Gigabit core hloov.

Cov ntsiab lus tseem ceeb ntawm kev xaiv hloov pauv
Thaum xaiv qhov hloov pauv rau kev soj ntsuam video hauv ib cheeb tsam hauv cheeb tsam network, vim hais tias lub siab tseem ceeb yog nyob rau ntawm cov txheej txheem sib sau ua ke, cov txheej txheem sib sau ua ke yuav tsum tau dais lub siab ntawm kev saib xyuas thiab khaws cov tsheb khiav nrog rau lub siab ntawm lub sijhawm saib thiab hu. saib xyuas. Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los xaiv qhov kev hloov pauv uas siv tau. Nws raug nquahu kom xaiv lub gigabit tswj kev hloov, uas tuaj yeem teeb tsa lub network, ua kom zoo dua thiab ua kom qhov kev siv bandwidth, thiab xyuas kom meej qhov kev sib kis.

Cov kev ceev faj
Yog tias koj xaiv Web-managed hloov tswj, nws yuav yooj yim dua. Nws yog qhov zoo tshaj plaws los xaiv qhov hloov pauv ceev, thiab thaum xaiv qhov hloov pauv nrog lub cache loj, tib lub sijhawm, lub network saib xyuas yuav tsum muaj kev ruaj ntseg thiab kev ua haujlwm tiag tiag, thiab cov cuab yeej ua haujlwm ib puag ncig yog qhov nyuaj thiab hnyav, yog li rau kev tiv thaiv Rau kev ruaj khov thiab ua haujlwm tau zoo ntawm cov ntaub ntawv kaw lus, nws raug nquahu kom xaiv cov khoom lag luam Ethernet hloov khoom nrog kev ua haujlwm siab thiab kev ruaj ntseg zoo.
