Isebenza kanjani i-Sbc Kusistimu Yokuthumela I-IP kanye Nohlelo Lokubheka
• Uhlolojikelele
Ngokuthuthuka okusheshayo kwe-IP kanye nobuchwepheshe bolwazi, uhlelo lokulwa nomlilo kanye nesistimu yokuhlenga izimo eziphuthumayo ihlala ithuthuka futhi ithuthukiswa.Isistimu yokuthunyelwa kwe-IP ehlanganiswe nezwi, ividiyo kanye nedatha isiyingxenye ebalulekile yesimo esiphuthumayo, umyalo kanye nohlelo lokuthunyelwa, ukuze kufezeke umyalo ohlangene nokuxhumana phakathi kwamasayithi ahlukene neminyango, kanye nokufeza ukuqapha kwesikhathi sangempela, ukusabela okusheshayo nangempumelelo kwezokuphepha. izehlakalo.
Kodwa-ke, ukuthunyelwa kohlelo lokuthunyelwa kwe-IP nakho kubhekene nezinselelo ezintsha.
Ungaqinisekisa kanjani ukuphepha kwesistimu ewumgogodla futhi uvimbele ukuhlaselwa kwenethiwekhi lapho iseva yebhizinisi neseva yemidiya ixhumana namadivayisi angaphandle nge-inthanethi?
Ungaqinisekisa kanjani ukusebenzisana okujwayelekile kokugeleza kwedatha yebhizinisi endaweni ye-NAT yenethiwekhi lapho iseva isetshenziswa ngemuva kwe-firewall?
Ukuqapha ividiyo, ukubuyiswa kokusakaza kwevidiyo nezinye izinsiza ngokuvamile kuhilela izihloko ezikhethekile ze-SIP nezinqubo ezikhethekile zokusayina.Ungaqinisekisa kanjani ukuxhumana okuzinzile kokusayina kanye nabezindaba phakathi kwezinhlangothi zombili?
Indlela yokuhlinzeka ngokuxhumana okuzinzile nokuthembekile, ukuqinisekisa i-QoS yokusakaza komsindo nevidiyo, ukulawula ukusayina nokuphepha?
Ukukhipha Isilawuli Somngcele Wesikhathi Se-Cashly Session emaphethelweni okuthumela kanye neseva yemidiya kungaxazulula izinselele ezingenhla ngempumelelo.
I-Topology ye-Scenario
Izici&Izinzuzo
Ukuvikela ukuhlasela kwe-DOS / DDoS, ukuvikela ukuhlasela kwe-IP, ukuvikela ukuhlasela kwe-SIP nezinye izinqubomgomo zokuphepha zokuvikela uhlelo.
Ukunqamula kwe-NAT ukuze kuqinisekiswe ukuxhumana kwenethiwekhi okushelelayo.
Izinsizakalo ze-QoS, ukuqapha ikhwalithi/ukubika ukuthuthukisa ikhwalithi yomsindo nevidiyo.
Ukusakazwa kwemidiya ye-RTMP, imephu ye-ice port kanye nommeleli we-HTTP.
Sekela indlela yengxoxo nengaphandle kwengxoxo SIP MESSAGE, kulula ukubhalisa ukusakazwa kwevidiyo.
Isihloko se-SIP nokukhohlisa kwenombolo ukuze kuhlangatshezwane nezidingo ezihlukahlukene zezimo ezihlukene.
Ukutholakala Okuphezulu: 1+1 i-hardware redundancy ukuze kuqinisekiswe ukuqhubeka komsebenzi.
Ikesi 1: I-Sbc ku-Forest Video Surveillance System
Isiteshi somlilo wehlathi, esibhekele ukusha kwehlathi nokunye ukuhlenga izinhlekelele zemvelo, sifuna ukwakha uhlelo lokuxhumana lokuthunyelwa kwe-IP, olusebenzisa kakhulu i-Unmanned Aerial Vehicle (UAV) ukuqapha nokusakaza izingcingo, nokudlulisa ividiyo yesikhathi sangempela nge-wireless. inethiwekhi eya esikhungweni sedatha.Uhlelo luhlose ukufinyeza kakhulu isikhathi sokuphendula kanye nokwenza lula ukuthunyelwa nokuyala okukude ngokushesha.Kulolu hlelo, i-Cashly Sbc isetshenziswa esikhungweni sedatha njengesango lomngcele leseva yokusakaza kwemidiya kanye nesistimu yokuthumela ewumgogodla, ehlinzeka ngohlelo lokuvikela olubonisa izimpawu, i-NAT traversal kanye nesevisi yokubhalisela ukusakaza ividiyo ohlelweni.
I-Network Topology
Izici Eziyinhloko
Ukuphatha: ukuphathwa kwabasebenzi, ukuphathwa kweqembu, ukuqapha izimo kanye nokusebenzisana phakathi kwamaqembu neminyango esabalalisiwe
Ukuqapha ividiyo: ukudlala ividiyo ngesikhathi sangempela, ukuqoshwa kwevidiyo nokugcinwa njll.
Ukuthunyelwa komsindo we-IP: ikholi eyodwa, iqembu lokupheja njll.
Ukuxhumana okuphuthumayo: isaziso, imiyalelo, ukuxhumana ngombhalo njll.
Izinzuzo
I-Sbc isebenza njengommeleli we-SIP ophumayo.Ukukhipha ama-app kanye neziphetho zohlelo lokusebenza lweselula zingabhalisa neseva yokuxhumana ehlanganisiwe nge-Sbc.
I-RTMP isakaza ummeleli wemidiya, i-Sbc idlulisela phambili ukusakazwa kwevidiyo ye-UAV kuseva yemidiya.
Imephu yembobo ye-ICE kanye nommeleli we-HTTP.
Qaphela isevisi yekhasimende ye-FEC yokusakaza ividiyo ngokudlula kwesihloko se-Sbc.
Ukuxhumana ngezwi, i-SIP intercom phakathi kokuthumela ikhonsoli nohlelo lokusebenza lweselula.
Isaziso se-SMS, i-Sbc isekela isaziso se-SMS ngendlela ye-SIP MESSAGE.
Konke ukusayinda nokusakazwa kwemidiya kudinga ukudluliselwa esikhungweni sedatha yi-Sbc, engaxazulula izinkinga zokuhambisana kwephrothokholi, ukuvundla kwe-NAT nokuvikeleka.
Icala lesi-2: I-Sbc isiza amabhizinisi e-petrochemical ukuthi akhiphe ngempumelelo isistimu yokuqapha ividiyo
Indawo yokukhiqiza yamabhizinisi amakhemikhali imvamisa ingaphansi kwezinga lokushisa eliphezulu, ukucindezela okukhulu, isivinini esikhulu, nezinye izimo ezimbi kakhulu.Izinto ezihilelekile ziyavutha, ziyaqhuma, zinobuthi kakhulu futhi ziyagqwala.Ngakho-ke, ukuphepha ekukhiqizeni kuyisisekelo sokusebenza okuvamile kwamabhizinisi amakhemikhali.Ngokuthuthuka kwesayensi nobuchwepheshe, uhlelo lokubhekwa kwevidiyo seluyingxenye ebalulekile yokukhiqizwa kokuphepha kwamabhizinisi amakhemikhali.Ukubhekwa kwevidiyo kufakwa ezifundeni eziyingozi, futhi isikhungo esikude singaqapha isimo sikude futhi ngesikhathi sangempela, ukuthola izingozi ezingaba khona zezingozi esizeni futhi senze ukwelashwa okungcono kwezimo eziphuthumayo.
I-Topology
Izici Eziyinhloko
Amakhamera afakwe endaweni ngayinye ebalulekile epaki ye-petrochemical, futhi inkundla yokuqapha ekude ingabuka ividiyo ngokungahleliwe.
Iseva yevidiyo ixhumana neseva ye-SIP ngephrothokholi ye-SIP futhi isungula uxhumano lwenethiwekhi phakathi kwekhamera nesikhungo sokuqapha.
Inkundla yokuqapha idonsa ukusakazwa kwevidiyo yekhamera ngayinye ngendlela ye-SIP MESSAGE.
Ukuqapha ngesikhathi sangempela esikhungweni esikude.
Ukurekhodwa kwevidiyo kugcinwa endaweni eyodwa ukuze kuqinisekiswe ukuthi inqubo yokuthumela neyomyalo irekhodwa kahle.
Izinzuzo
Xazulula udaba lwe-NAT futhi uqinisekise ukuxhumana okushelelayo phakathi kwamakhamera nesikhungo sokuqapha esikude.
Hlola ividiyo yekhamera ngobhalisile we-SIP MESSAGE.
Lawula i-engeli yamakhamera ngesikhathi sangempela usebenzisa i-SIP signaling passthrough.
Ukudlula kwesihloko se-SDP kanye nokukhohlisa ukuze kuhlangatshezwane nezidingo zebhizinisi ezahlukahlukene.
Xazulula izinkinga zokusebenzisana nge-sbc SIP unhlokweni ngokukhohlisa ngokumisa imilayezo ye-SIP ethunyelwe amaseva evidiyo.
Dlulisela phambili isevisi yevidiyo emsulwa ngomlayezo we-SIP (umlayezo wontanga we-SDP uhlanganisa ividiyo kuphela, awukho umsindo).
Khetha ukusakazwa kwevidiyo kwesikhathi sangempela sekhamera ehambisanayo ngesici sokukhohlisa inombolo ye-sbc.
