Isebenza njani i-Sbc kwi-IP Dispatching System kunye neNkqubo yokuHlola
• Isishwankathelo
Ngophuhliso olukhawulezayo lwe-IP kunye nobuchwepheshe bolwazi, ukulwa nomlilo kunye nenkqubo yokuhlangula ngokukhawuleza ihlala iphucula kwaye iphucula. Inkqubo yokuthunyelwa kwe-IP edibeneyo kunye nezwi, ividiyo kunye nedatha ibe yinxalenye ebalulekileyo yexakeka, umyalelo kunye nenkqubo yokuthumela, ukuqonda umyalelo odibeneyo kunye nokulungelelaniswa phakathi kweendawo ezahlukeneyo kunye namasebe, kunye nokufezekisa ukubeka iliso ngexesha langempela, ukuphendula ngokukhawuleza nangokufanelekileyo kukhuseleko. iziganeko.
Nangona kunjalo, ukuthunyelwa kwenkqubo yokuthunyelwa kwe-IP nayo ijongene nemingeni emitsha.
Indlela yokuqinisekisa ukhuseleko lwenkqubo engundoqo kunye nokuthintela ukuhlaselwa kwenethiwekhi xa umncedisi woshishino kunye nomncedisi weendaba enxibelelana nezixhobo zangaphandle nge-Intanethi?
Indlela yokuqinisekisa ukusebenzisana okuqhelekileyo kokuhamba kwedatha yeshishini kwindawo ye-NAT yomnqamlezo xa iseva ibekwe emva komlilo?
Ukujongwa kwevidiyo, ukubuyiswa kwevidiyo kunye nezinye iinkonzo zihlala zibandakanya iintloko ze-SIP ezikhethekileyo kunye neenkqubo ezikhethekileyo zokubonisa. Indlela yokuqinisekisa unxibelelwano oluzinzileyo lokusayina kunye nemidiya phakathi kwamaqela omabini?
Indlela yokubonelela ngonxibelelwano oluzinzileyo noluthembekileyo, uqinisekise i-QoS yomsindo kunye nevidiyo yomsindo, ukulawula ukubonakaliswa kunye nokhuseleko?
Ukuthumela i-Cashly Session Border Controller kumda wokuthumela kunye nomncedisi weendaba unokusombulula ngempumelelo le mingeni ingentla.

I-Case 1: Sbc kwi-Forest Video Surveillance System
Isikhululo somlilo wehlathi, ojongene nomlilo wehlathi kunye nolunye uhlangulo lwentlekele yendalo, ufuna ukwakha inkqubo yonxibelelwano yokuthumela i-IP, esebenzisa kakhulu i-Unmanned Aerial Vehicle (UAV) ukujonga ngeenxa zonke kunye nokusasaza iifowuni, kunye nokuhambisa ividiyo yexesha langempela nge-wireless. inethiwekhi kwiziko ledatha. Inkqubo ijolise ekunciphiseni kakhulu ixesha lokuphendula kwaye iququzelele ukuthunyelwa ngokukhawuleza kunye nomyalelo. Kule nkqubo, i-Cashly Sbc isetyenziswe kwiziko ledatha njengesango lomda we-media stream server kunye ne-core dispatching system, ebonelela nge-firewall yokubonisa, i-NAT traversal kunye nenkonzo yokubhaliselwa kwevidiyo kwi-system.
I-Network Topology
Ezona mpawu
Ulawulo: ulawulo lwabasebenzi, ulawulo lweqela, ukubeka iliso kwimo engqongileyo kunye nentsebenziswano phakathi kwamaqela asasaziweyo kunye namasebe
Ukujongwa kwevidiyo: ixesha lokwenyani lokudlala ividiyo, ukurekhodwa kwevidiyo kunye nokugcinwa njl.
Ukuhanjiswa komsindo we-IP: umnxeba omnye, iqela lepheyija njl.
Unxibelelwano olungxamisekileyo: isaziso, umyalelo, unxibelelwano lombhalo njl.
Iingenelo
I-Sbc isebenza njengommeli we-SIP ophumayo. Ukuthumela i-app kunye neendawo zokuphela ze-app eziphathwayo zinokubhalisa kunye neseva yonxibelelwano olumanyeneyo nge-Sbc.
I-RTMP yokusasaza i-proxy yemidiya, i-Sbc idlulisela phambili ividiyo ye-UAV kwiseva yemidiya.
