Indlela i-Sbc Esebenza Ngayo Kuhlelo Lokusabalalisa i-IP kanye Nohlelo Lokuqapha
• Ukubuka konke
Ngokuthuthuka okusheshayo kwe-IP kanye nobuchwepheshe bolwazi, uhlelo lokulwa nomlilo kanye nohlelo lokutakula oluphuthumayo luhlala luthuthuka futhi luthuthukiswa. Uhlelo lokuthumela i-IP oluhlanganiswe nezwi, ividiyo kanye nedatha seluyingxenye ebalulekile yohlelo oluphuthumayo, lokulawula kanye nokuthumela, ukuze kufezwe umyalo kanye nokuxhumana okuhlangene phakathi kwezindawo ezahlukene kanye neminyango, kanye nokufeza ukuqapha ngesikhathi sangempela, impendulo esheshayo nephumelelayo ezigamekweni zokuphepha.
Kodwa-ke, ukuthunyelwa kohlelo lokuthumela i-IP nakho kubhekene nezinselele ezintsha.
Ungaqinisekisa kanjani ukuphepha kwesistimu eyinhloko nokuvimbela ukuhlaselwa kwenethiwekhi lapho iseva yebhizinisi kanye neseva yemidiya bexhumana namadivayisi angaphandle nge-inthanethi?
Ungaqinisekisa kanjani ukusebenzisana okujwayelekile kokugeleza kwedatha yebhizinisi endaweni ye-NAT yenethiwekhi lapho iseva isetshenziswa ngemuva kwe-firewall?
Ukuqapha ividiyo, ukubuyisa ukusakazwa kwevidiyo kanye nezinye izinsizakalo ngokuvamile kuhilela izihloko ezithile ze-SIP ezikhethekile kanye nezinqubo ezikhethekile zokubonisa izimpawu. Ungaqinisekisa kanjani ukuxhumana okuzinzile kokubonisa izimpawu kanye nabezindaba phakathi kwezinhlangothi zombili?
Ungakunikeza kanjani ukuxhumana okuzinzile nokuthembekile, uqinisekise i-QoS yokusakazwa komsindo nevidiyo, ukulawula izimpawu kanye nokuphepha?
Ukufaka i-Cashly Session Border Controller emaphethelweni okuthumela kanye neseva yemidiya kungaxazulula ngempumelelo izinselele ezingenhla.
I-Topology ye-Scenario
Izici nezinzuzo
Ukuvikela ukuhlasela kwe-DOS / DDoS, ukuvikela ukuhlasela kwe-IP, ukuvikela ukuhlasela kwe-SIP kanye nezinye izinqubomgomo zokuphepha ze-firewall ukuvikela uhlelo.
Ukuhamba kwe-NAT ukuqinisekisa ukuxhumana kwenethiwekhi okubushelelezi.
Izinsizakalo ze-QoS, ukuqapha/ukubika ikhwalithi ukuthuthukisa ikhwalithi yomsindo nevidiyo.
Ukusakaza kwemidiya ye-RTMP, ukumepha i-ice port kanye ne-HTTP proxy.
Sekela indlela ye-SIP MESSAGE engaphakathi kwengxoxo kanye nendlela ye-out-of-dialog, kulula ukubhalisela ukusakazwa kwevidiyo.
Isihloko se-SIP kanye nokuguqulwa kwezinombolo ukuze kuhlangatshezwane nezidingo ezahlukene zezimo ezahlukene.
Ukutholakala Okuphezulu: Ukuphindaphinda kwehadiwe okungu-1+1 ukuqinisekisa ukuqhubeka kokusebenza.
Icala 1: Uhlelo Lokuqapha Amavidiyo e-Sbc Ehlathini
Isiteshi somlilo wehlathi, esinomthwalo womlilo wehlathi kanye nokunye ukuhlenga izinhlekelele zemvelo, sifuna ukwakha uhlelo lokuxhumana lokuthumela i-IP, olusebenzisa kakhulu i-Unmanned Aerial Vehicle (UAV) ukuqapha nokusakaza izingcingo, nokudlulisa ividiyo yesikhathi sangempela ngenethiwekhi engenantambo esikhungweni sedatha. Uhlelo luhlose ukufinyeza kakhulu isikhathi sokuphendula futhi lwenze kube lula ukuthumela ngokushesha nokuyala okukude. Kulesi simiso, i-Cashly Sbc isetshenziswa esikhungweni sedatha njengesango lomngcele leseva yokusakaza imidiya kanye nohlelo lokuthumela oluyinhloko, oluhlinzeka nge-firewall yesignaling, i-NAT traversal kanye nensizakalo yokubhalisa ukusakaza ividiyo ohlelweni.
I-Topology Yenethiwekhi
Izici Eziyinhloko
Ukuphatha: ukuphathwa kwabasebenzi, ukuphathwa kwamaqembu, ukuqapha izindawo kanye nokubambisana phakathi kwamaqembu neminyango esakazekile
Ukuqapha ividiyo: ukudlala ividiyo ngesikhathi sangempela, ukuqoshwa kwevidiyo kanye nokugcina njll.
Ukuthunyelwa komsindo we-IP: ucingo olulodwa, iqembu le-paging njll.
Ukuxhumana okuphuthumayo: isaziso, imiyalelo, ukuxhumana ngombhalo njll.
Izinzuzo
I-Sbc isebenza njengommeleli we-SIP ophumayo. Ama-endpoints okuthumela uhlelo lokusebenza kanye nohlelo lokusebenza lweselula angabhaliswa kuseva yokuxhumana ehlanganisiwe nge-Sbc.
I-RTMP idlulisela ividiyo ye-UAV kuseva yemidiya.
Ukumapha kwe-ICE port kanye ne-HTTP proxy.
Qaphela isevisi yokubhalisa ukusakazwa kwevidiyo ye-FEC yamakhasimende nge-passthrough yekhanda le-Sbc.
Ukuxhumana ngezwi, i-intercom ye-SIP phakathi kwekhonsoli yokuthumela kanye nohlelo lokusebenza lweselula.
Isaziso se-SMS, i-Sbc isekela isaziso se-SMS ngendlela ye-SIP MESSAGE.
Konke ukusakazwa kwesignali kanye nemidiya kudinga ukuthunyelwa esikhungweni sedatha yi-Sbc, okungaxazulula izinkinga zokuhambisana kwephrothokholi, ukuzulazula kwe-NAT kanye nokuphepha.
Icala 2: I-Sbc isiza amabhizinisi e-petrochemical ukuthi asebenzise ngempumelelo uhlelo lokuqapha ividiyo
Indawo yokukhiqiza yamabhizinisi amakhemikhali ngokuvamile ingaphansi kokushisa okuphezulu, umfutho ophezulu, isivinini esikhulu, nezinye izimo ezimbi kakhulu. Izinto ezihilelekile ziyavutha, ziyaqhuma, zinobuthi kakhulu, futhi ziyagqwala. Ngakho-ke, ukuphepha ekukhiqizeni kuyisiqalo sokusebenza okuvamile kwamabhizinisi amakhemikhali. Ngokuthuthuka kwesayensi nobuchwepheshe, uhlelo lokuqapha ividiyo selube yingxenye ebalulekile yokukhiqizwa kokuphepha kwamabhizinisi amakhemikhali. Ukuqapha ividiyo kufakwa ezindaweni eziyingozi, futhi isikhungo esikude singaqapha isimo kude nangesikhathi sangempela, ukuthola izingozi ezingaba khona endaweni futhi senze ukwelashwa okuphuthumayo okungcono.

Izici Eziyinhloko
Amakhamera afakwa endaweni ngayinye ebalulekile epaki likaphethiloli, futhi ipulatifomu yokuqapha ekude ingabuka ividiyo ngokungahleliwe.
Iseva yevidiyo ixhumana neseva ye-SIP ngephrothokholi ye-SIP futhi isungula uxhumano lwenethiwekhi phakathi kwekhamera nesikhungo sokuqapha.
Ipulatifomu yokuqapha idonsa ukusakazwa kwevidiyo kwekhamera ngayinye ngendlela ye-SIP MESSAGE.
Ukuqapha ngesikhathi sangempela esikhungweni esikude.
Ukuqoshwa kwamavidiyo kugcinwa phakathi nendawo ukuqinisekisa ukuthi inqubo yokuthumela kanye neyokuyala iqoshwa kahle.
Izinzuzo
Xazulula inkinga yokudlula kwe-NAT futhi uqinisekise ukuxhumana okubushelelezi phakathi kwamakhamera nesikhungo sokuqapha esikude.
Hlola ividiyo yekhamera ngobhalisile we-SIP MESSAGE.
Lawula i-engeli yamakhamera ngesikhathi sangempela nge-passthrough yesignali ye-SIP.
Ukudlula kanye nokuphathwa kwekhanda le-SDP ukuze kuhlangatshezwane nezidingo zebhizinisi ezahlukahlukene.
Xazulula izinkinga zokuhambisana ngokushintsha izihloko ze-sbc SIP ngokwenza imiyalezo ye-SIP ethunyelwe ngamaseva evidiyo ibe yifomethi efanayo.
Dlulisa isevisi yevidiyo emsulwa ngomlayezo we-SIP (umyalezo we-peer SDP uhlanganisa ividiyo kuphela, awukho umsindo).
Khetha ukusakazwa kwevidiyo kwesikhathi sangempela kwekhamera ehambisanayo ngesici sokushintshanisa izinombolo ze-sbc.
