Yuav ua li cas Sbc ua haujlwm hauv IP Dispatching System thiab Surveillance System
• Txheej txheem cej luam
Nrog rau kev loj hlob sai ntawm IP thiab thev naus laus zis, lub kaw lus tua hluav taws thiab kev cawm neeg thaum muaj xwm txheej ceev tau txhim kho thiab hloov kho tas li. IP dispatching system sib xyaw nrog lub suab, video thiab cov ntaub ntawv tau dhau los ua ib feem tseem ceeb ntawm kev kub ntxhov, kev hais kom ua thiab kev xa tawm, kom paub txog kev hais kom ua thiab kev sib koom tes ntawm ntau qhov chaw thiab cov chav haujlwm, thiab kom ua tiav kev saib xyuas tiag tiag, kev teb sai thiab ua tau zoo rau cov xwm txheej kev ruaj ntseg.
Txawm li cas los xij, kev xa tawm ntawm IP dispatch system kuj tseem ntsib teeb meem tshiab.
Yuav ua li cas kom ntseeg tau tias muaj kev ruaj ntseg ntawm lub hauv paus system thiab tiv thaiv kev tawm tsam hauv network thaum lub lag luam server thiab media server sib txuas lus nrog cov khoom siv sab nraud los ntawm Is Taws Nem?
Yuav ua li cas kom ntseeg tau tias kev sib cuam tshuam ib txwm ntawm cov ntaub ntawv lag luam ntws hauv ib puag ncig NAT thaum lub server raug xa mus tom qab firewall?
Kev saib xyuas video, kev nrhiav cov yeeb yaj kiab thiab lwm yam kev pabcuam feem ntau yuav siv qee cov SIP headers tshwj xeeb thiab cov txheej txheem tshwj xeeb. Yuav ua li cas kom ntseeg tau tias kev sib txuas lus ruaj khov ntawm kev xa xov thiab xov xwm ntawm ob tog?
Yuav ua li cas los muab kev sib txuas lus ruaj khov thiab txhim khu kev qha, xyuas kom meej QoS ntawm cov suab thiab video kwj deg, kev tswj hwm kev taw qhia thiab kev ruaj ntseg?
Kev siv Cashly Session Border Controller ntawm ntug kev xa tawm thiab lub server xov xwm tuaj yeem daws tau cov teeb meem saum toj no.

Rooj Plaub 1: Sbc hauv Hav Zoov Video Saib Xyuas System
Ib lub chaw tua hluav taws hauv hav zoov, uas yog lub luag haujlwm rau hluav taws hauv hav zoov thiab lwm yam kev cawm neeg thaum muaj xwm txheej ntuj tsim, xav tsim kom muaj ib lub tshuab sib txuas lus IP, uas feem ntau siv Unmanned Aerial Vehicle (UAV) los saib xyuas thiab tshaj tawm cov xov tooj, thiab xa cov yeeb yaj kiab tiag tiag los ntawm wireless network mus rau lub chaw khaws ntaub ntawv. Lub hom phiaj ntawm lub tshuab no yog kom luv lub sijhawm teb thiab pab txhawb kev xa tawm thiab kev hais kom ua sai sai. Hauv lub tshuab no, Cashly Sbc tau muab tso rau hauv lub chaw khaws ntaub ntawv ua lub rooj vag ciam teb ntawm cov neeg rau zaub mov media stream thiab lub tshuab xa tawm tseem ceeb, uas muab cov signaling firewall, NAT traversal thiab kev pabcuam streaming video rau lub tshuab.
Network Topology
Cov Nta Tseem Ceeb
Kev Tswj: kev tswj cov neeg ua haujlwm, kev tswj pab pawg, saib xyuas ib puag ncig thiab kev koom tes ntawm cov pab pawg thiab cov chav haujlwm uas tau faib ua pawg
