• Kuyini ukulawulwa komngcele weseshini (SBC)
Isilawuli sesikhathi seseshini (SBC) iyinto esetshenziselwa inethiwekhi ukuvikela izwi elisekelwe kwi-SIP ngaphezulu kwamanethiwekhi we-Intanethi (VoIP). I-SBC isibe yi-De-Facto Standard ye-Telephony and Multimedia Services of NGN / IMS.

Izinkinga Zokuxhumana
I-Nat Guqula i-IP yangasese kwi-IP yangaphandle kepha ayikwazi ukuguqula i-IP yokufaka uhlelo lokusebenza. Ikheli le-IP le-IP alilungile, ngakho-ke alikwazi ukuxhumana nama-Endpoint.
I-NAT Transversal
I-Nat Guqula i-IP yangasese kwi-IP yangaphandle kepha ayikwazi ukuguqula i-IP yokufaka uhlelo lokusebenza. I-SBC ingakhomba i-NAT, shintsha ikheli le-IP le-SDP. Ngakho-ke thola ikheli le-IP elilungile ne-RTP kungafinyelela ama-Endpoints.

Izinkinga Zokuphepha
Ukuvikelwa Kokuhlasela
Q: Kungani kudingeka isilawuli somngcele weseshini sokuhlaselwa yi-VOIP?
A: Konke ukuziphatha kokuhlaselwa okuthile kwe-VOIP kuvumelana ne-protocol, kepha izimilo azivamile. Isibonelo, uma imvamisa yezingcingo iphezulu kakhulu, izodala ukulimala kwengqalasizinda yakho ye-VoIP. Ama-SBC angahlaziya ungqimba wohlelo lokusebenza futhi akhombe isimilo somsebenzisi.
Ukuvikelwa ngokweqile
Q: Yini ebangela ukulayisha ngokweqile komgwaqo?
A: Imicimbi eshisayo yimithombo ye-Trigger ejwayelekile kunazo zonke, efana nokuthenga okungu-11 eChina (njengoLwesihlanu Olumnyama e-USA), imicimbi eminingi, noma ukuhlaselwa okubangelwa izindaba ezingezinhle. Ukuhlinzwa okungazelelwe kokubhaliswa okubangelwa ukwehluleka kwamandla wedatha, ukwehluleka kwenethiwekhi nakho kungumthombo ojwayelekile we-trigger.
Q: I-SBC ivimba kanjani ukulayisha ngokweqile kwethrafikhi?
A: I-SBC ingahlela ukushushumbisi ngobuhlakani ngokuya ngezinga lomsebenzisi kanye nokubekwa phambili kwebhizinisi, ngokuqina okuphezulu kakhulu: isikhathi esigcwele esigcwele, ibhizinisi ngeke liphazanyiswe. Imisebenzi efana nomkhawulo / ukulawula, uhlu olunamandla olushukumisayo, ukubhaliswa / isilinganiso sokulinganisa umkhawulo njll.
Izindaba zokuhambisana
Ukusebenzisana phakathi kwemikhiqizo ye-SIP akuqinisekisiwe ngaso sonke isikhathi. Ama-SBC enza ukuxhumana komthungo.
Q: Kungani izinkinga zokusebenzisana zenzeka lapho wonke amadivaysi esekela i-SIP?
A: I-SIP iyindinganiso evulekile, abathengisi abahlukahlukene bavame ukuba nezincazelo ezahlukahlukene kanye nokuqalisa, okungadala ukuxhumana futhi
/ noma izindaba zomsindo.
Q: I-SBC ixazulula kanjani le nkinga?
A: Ama-SBCS asekela ukusatshalaliswa kwe-SIP nge-SIP umlayezo we-SIP kanye nokukhohlisa kwezinhloko. Inkulumo ejwayelekile nokungezwa / ukususa / ukuguqula / ukuguqula kutholakala kuma-Dinstar SBCS.
Ama-SBC aqinisekisa ikhwalithi yensiza (QOS)
Ukuphathwa kwezinhlelo eziningi kanye ne-multimedia kuyinkimbinkimbi. Umzila ojwayelekile
Kunzima ukubhekana ne-multimedia traffic, okuholele ekuxinekeni.
Hlaziya izingcingo zomsindo nevidiyo, ngokususelwa ekuziphatheni komsebenzisi.Call control
Ukuphatha: Umzila onobuhlakani osuselwa kumuntu ofonayo, amapharamitha we-SIP, isikhathi, Qos.
Lapho i-IP I-IP ingazinzile, ukulahleka kwephakethe nokubambezeleka kweJitter kubangela ikhwalithi embi
yenkonzo.
Ama-SBC aqapha ikhwalithi yocingo ngalunye ngesikhathi sangempela futhi uthathe izenzo ezisheshayo
ukuqinisekisa ama-Qos.
