Yuav Ua Li Cas Sbc Ua Haujlwm hauv IP Dispatching System thiab Kev Tshawb Fawb
• Txheej txheem cej luam
Nrog rau kev txhim kho sai ntawm IP thiab cov ntaub ntawv thev naus laus zis, kev sib ntaus sib tua hluav taws thiab kev pabcuam thaum muaj xwm txheej ceev tau txhim kho thiab kho dua tshiab.IP dispatching system ua ke nrog lub suab, yees duab 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 sib koom ua ke thiab kev sib koom ua ke ntawm cov chaw sib txawv thiab cov chaw ua haujlwm, thiab ua tiav kev saib xyuas lub sijhawm, sai thiab muaj txiaj ntsig zoo rau kev nyab xeeb. xwm txheej.
Txawm li cas los xij, kev xa tawm IP xa tawm kuj tseem ntsib cov teeb meem tshiab.
Yuav ua li cas kom muaj kev ruaj ntseg ntawm lub hauv paus system thiab tiv thaiv kev tawm tsam network thaum lub lag luam server thiab media server sib txuas lus nrog lwm cov khoom siv hauv Is Taws Nem?
Yuav ua li cas kom ntseeg tau qhov kev sib cuam tshuam ntawm kev lag luam cov ntaub ntawv ntws hauv cross network NAT ib puag ncig thaum lub server raug xa mus tom qab firewall?
Kev saib xyuas yees duab, yees duab kwj retrieval thiab lwm yam kev pab cuam feem ntau koom nrog qee qhov tshwj xeeb SIP headers thiab cov txheej txheem teeb liab tshwj xeeb.Yuav ua li cas kom muaj kev sib txuas lus ruaj khov ntawm kev teeb tsa thiab kev tshaj tawm ntawm ob tog?
Yuav ua li cas muab kev sib txuas lus ruaj khov thiab txhim khu kev qha, ua kom QoS ntawm lub suab thiab video kwj, teeb liab tswj thiab kev ruaj ntseg?
Siv Cashly Session Ciam Teb Tswjhwm ntawm ntug ntawm kev xa tawm thiab cov neeg siv xov xwm tuaj yeem daws cov teeb meem saum toj no.

Case 1: Sbc in Forest Video Surveillance System
Lub chaw tua hluav taws hauv hav zoov, uas yog lub luag haujlwm rau kev tua hluav taws thiab lwm yam kev puas tsuaj ntuj tsim, xav tsim kom muaj kev sib txuas lus IP, uas feem ntau yog siv Unmanned Aerial Vehicle (UAV) los saib xyuas ib puag ncig thiab tshaj tawm xov tooj, thiab xa cov vis dis aus real-time los ntawm wireless. network rau cov ntaub ntawv center.Lub kaw lus aims kom luv luv lub sij hawm teb thiab pab sai sai tej thaj chaw deb dispatching thiab hais kom ua.Hauv cov kab ke no, Cashly Sbc tau xa mus rau hauv cov ntaub ntawv chaw ua haujlwm ciam teb ntawm cov xov xwm kwj server thiab cov tub ntxhais xa xov xwm, uas yog muab cov phiaj xwm hluav taws xob, NAT traversal thiab video streaming subscription service rau lub kaw lus.
Network Topology
Cov yam ntxwv tseem ceeb
Kev tswj hwm: kev tswj cov neeg ua haujlwm, kev tswj xyuas pab pawg, saib xyuas ib puag ncig thiab kev sib koom tes ntawm cov pab pawg thiab cov tuam haujlwm
Kev saib xyuas video: real-time video playback, video kaw thiab cia thiab lwm yam.
IP audio dispatching: ib leeg hu, pab pawg paging thiab lwm yam.
Kev sib txuas lus xwm ceev: ceeb toom, qhia, kev sib txuas lus thiab lwm yam.
Cov txiaj ntsig
Sbc ua hauj lwm raws li outbound SIP proxy.Dispatching app thiab mobile app endpoints tuaj yeem sau npe nrog kev sib txuas lus server los ntawm Sbc.
RTMP streaming media proxy, Sbc xa tawm cov kwj video ntawm UAV rau cov neeg siv xov xwm.
ICE chaw nres nkoj mapping thiab HTTP npe.
Paub txog cov neeg siv khoom FEC video stream subscription service los ntawm Sbc header passthrough.
