Li cas SBC ua haujlwm hauv Ip xa tawm system thiab kev soj ntsuam cov kab ke
• Txheej txheem cej luam
Nrog kev txhim kho sai ntawm IP thiab cov ntaub ntawv thev naus laus zis, kev sib ntaus hluav taws thiab kev cawm kom xwm txheej ceev yog kev txhim kho thiab kev txhim kho. IP cov ntawv xa tawm ua ke nrog lub suab, video thiab cov ntaub ntawv tau dhau los ua kev kub ntxhov, kom paub cov kev cai sib txawv, thiab kom tau txais kev soj ntsuam tiag tiag, thiab ua kom sai thiab muaj txiaj ntsig zoo rau kev ruaj ntseg xwm txheej.
Txawm li cas los xij, kev xa tawm ntawm IP cov txheej txheem Displatch kuj tseem ntsib cov kev cov nyom tshiab.
Yuav ua li cas kom ntseeg tau tias cov txheej txheem tseem ceeb thiab tiv thaiv kev tawm tsam network thaum lub lag luam server thiab media tshaj tawm hauv Is Taws Nem?
Yuav ua li cas kom ntseeg tau tias qhov kev sib cuam tshuam ib txwm muaj ntawm cov ntaub ntawv txaus khiav hauv hla Network Nat ib puag ncig thaum tus neeg rau zaub mov tau tom qab firewall?
Kev soj ntsuam video, Video Stream Suppieval thiab lwm cov kev pabcuam feem ntau muaj qee cov txheej txheem tshwj xeeb siph headers thiab cov txheej txheem tshwj xeeb. Yuav ua li cas kom tau kev sib txuas lus ruaj khov ntawm kev kos npe thiab xov xwm nruab nrab ntawm ob tog?
Yuav ua li cas muab kev sib txuas lus ruaj khov thiab txhim khu kev qha, kom QOS ntawm audio thiab video ntws, signaling tswj thiab kev nyab xeeb?
Deploying kev sib koom tes sib koom tes ciam teb ntawm ntug kev xa tawm thiab Media server tuaj yeem daws cov kev cov nyom saum toj no.
Topology ntawm Scenario

SIP Header thiab Tooj Mothaw kom tau raws li cov kev xav tau ntawm cov xwm txheej sib txawv.
Kev muaj peev xwm muaj: 1 + 1 kho vajtse refundancy kom ntseeg tau kev ua haujlwm txuas ntxiv.
Rooj plaub 1: SBC hauv Hav Zoov Video Saib Xyuas System
Chaw nres tsheb hluav taws, uas yog lub luag haujlwm rau cov hluav taws hav zoov thiab lwm yam kev sib txuas lus uas tsis muaj kev sib txuas lus, thiab xa cov vis dis aus, thiab xa tawm cov yeeb yaj kiab tiag tiag los ntawm Wireless Network rau cov ntaub ntawv chaw. Lub kaw lus lub hom phiaj kom luv luv lub sijhawm teb thiab pab txhawb cov chaw taws teeb nrawm nrawm thiab cov lus txib. Hauv cov kab ke no, nyiaj txiag sbc tau tso tawm hauv cov ntaub ntawv chaw ntawm cov chaw sib koom ua ke ntawm cov kev pabcuam firewall, nat traversal thiab video streaming subscription kev pab rau lub system.
Network Topology
Cov Nta Tseem Ceeb
Kev Tswj Xyuas: Cov Neeg Tswj Cov Neeg Ua Haujlwm, Kev Tswj Xyuas Pab Pawg, ib puag ncig thiab kev sib koom tes nrog pawg neeg thiab cov haujlwm
Yees duab soj ntsuam: REO-lub sijhawm video playback, video kaw cia thiab cia thiab lwm yam.
IP suab tawm: ib qho hu, paging pawg thiab lwm yam.
Kev sib txuas lus xwm ceev: Kev Ceeb Toom, kev qhia, cov ntawv sib txuas lus thiab lwm yam.
Cov txiaj ntsig
SBC ua haujlwm li sab nraud SIP proxy. Kev xa tawm app thiab txawb app kawg twg tuaj yeem sau npe nrog kev sib txuas lus hauv SBC.
RTMP streaming Media Proxy, SBC forwards qhov video ntws ntawm UAV rau Media Server.
Cov chaw nres nkoj khov thiab HTTXY.
Paub txog tus neeg siv FEC video tso cov kev pab ua ntej los ntawm SBC header passthrough.
Lub suab kev sib txuas lus, SIP intercom ntawm kev xa cov console thiab txawb app.
SMS Kev Ceeb Toom, SBC txhawb nqa SMS Ceeb Toom ntawm SAM kev qhia.
Tag nrho cov paib thiab xov xwm tshaj tawm yuav tsum tau xa mus rau cov ntaub ntawv chaw los ntawm SBC, uas tuaj yeem daws cov teeb meem ntawm raws tu protocol sib txuam, nat traversal thiab kev nyab xeeb.
Rooj plaub 2: SBC pab petrochemical qhauj petrochemical ntse ua tiav cov video screenillance system
Qhov kev tsim ntau lawm ntawm cov chaw lag luam tshuaj yog feem ntau raws li qhov kub, kev kub siab, kev kub siab, thiab lwm yam kev mob siab. Cov ntaub ntawv muaj kev cuam tshuam nrog cov nplaim taws, tawg, muaj kuab heev, thiab corrosive. Yog li ntawd, kev nyab xeeb nyob rau hauv kev tsim khoom yog qhov ua ntej ntawm kev khiav ntawm kev ua lag luam tshuaj lom neeg. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, kev soj ntsuam video tau dhau los ua ib feem tseem ceeb ntawm kev nyab xeeb kev nyab xeeb ntawm cov kev lag luam tshuaj lom neeg. Kev soj ntsuam video yog teeb tsa nyob rau hauv thaj chaw txaus ntshai, thiab thaj chaw deb chaw tuaj yeem soj ntsuam qhov xwm txheej deb ntawm kev raug mob ntawm cov xwm txheej thiab ua kom muaj kev kho mob kom ceev.
Lub ntsiab
Cov Nta Tseem Ceeb
