• Kuyini iSession Border Controller (SBC)
I-Session Border Controller (SBC) iyisici senethiwekhi esisetshenziselwa ukuvikela amanethiwekhi ezwi asekelwe ku-SIP nge-Internet Protocol (VoIP). I-SBC isibe yindinganiso yangempela yezinsizakalo zefoni nezokuxhumana ze-NGN / IMS.

| Ukuxhumana phakathi kwamaqembu amabili. Lokhu kungaba umlayezo wokubonisa ucingo, umsindo, ividiyo, noma olunye ulwazi kanye nolwazi lwezibalo zezingcingo kanye nekhwalithi. | Iphuzu lokuhlukanisa phakathi kwengxenye eyodwa ye inethiwekhi kanye nokunye. | Ithonya labalawuli bemingcele yeseshini abanalo emifudlaneni yedatha ehlanganisa izikhathi ezifana nokuphepha, ukulinganisa, ukulawula ukufinyelela, ukuqondisa, isu, ukusayina, imidiya, i-QoS kanye nezindawo zokuguqula idatha zezingcingo abazilawulayo. |

| Akukho zwi/izwi elivela ohlangothini olulodwa elibangelwa yi-NAT phakathi kwamanethiwekhi amancane ahlukene. | Ngeshwa, ukusebenzisana phakathi kwemikhiqizo ye-SIP yabathengisi abahlukene akuqinisekisiwe ngaso sonke isikhathi. | Ukungena kwezinsizakalo, ukulalela izindaba, ukwenqatshwa kokuhlaselwa kwezinsizakalo, ukubanjwa kwedatha, ukukhwabanisa ngezindleko zomgwaqo, amaphakethe e-SIP angasebenzi kahle kungadala ukulahlekelwa okukhulu kuwe. |
Izinkinga Zokuxhumana
I-NAT iguqula i-IP yangasese ibe yi-IP yangaphandle kodwa ayikwazi ukuguqula i-IP yesendlalelo sohlelo lokusebenza. Ikheli le-IP yendawo alilungile, ngakho-ke ayikwazi ukuxhumana nama-endpoints.
I-NAT Transversal
I-NAT iguqula i-IP yangasese ibe yi-IP yangaphandle kodwa ayikwazi ukushintsha i-IP yesendlalelo sohlelo lokusebenza. I-SBC ingakwazi ukubona i-NAT, ishintshe ikheli le-IP le-SDP. Ngakho-ke ithole ikheli le-IP elifanele futhi i-RTP ingafinyelela amaphuzu okuphela.
Isilawuli Semingcele Yeseshini sisebenza njengommeleli wethrafikhi ye-VoIP
Izinkinga Zokuphepha
Ukuvikelwa Kokuhlasela
Q: Kungani kudingeka iSession Border Controller ekuhlaselweni kwe-VoIP?
A: Zonke izindlela zokuziphatha zokuhlasela kwe-VoIP ezithile ziyahambisana nephrothokholi, kodwa izindlela zokuziphatha azivamile. Isibonelo, uma imvamisa yokushaya ucingo iphezulu kakhulu, izodala umonakalo engqalasizinda yakho ye-VoIP. Ama-SBC angahlaziya ungqimba lohlelo lokusebenza futhi abone izindlela zokuziphatha zomsebenzisi.
Ukuvikelwa Kokulayisha Okungaphezu Komthwalo
Q: Yini ebangela ukugcwala ngokweqile kwethrafikhi?
A: Imicimbi eshisayo iyimithombo evame kakhulu yezimbangela, njengokuthenga kabili kwe-11 eShayina (njenge-Black Friday e-USA), imicimbi emikhulu, noma ukuhlaselwa okubangelwa izindaba ezimbi. Ukwanda okungazelelwe kokubhaliswa okubangelwa ukwehluleka kwamandla esikhungo sedatha, ukwehluleka kwenethiwekhi nakho kuwumthombo ovamile wezimbangela.
Q: i-SBC ikuvimbela kanjani ukugcwala kwethrafikhi?
A: I-SBC ingahlela ithrafikhi ngobuhlakani ngokuya ngezinga lomsebenzisi kanye nokubaluleka kwebhizinisi, ngokumelana okuphezulu kokulayisha ngokweqile: ukulayisha ngokweqile okuphindwe kathathu, ibhizinisi ngeke liphazanyiswe. Imisebenzi efana nokunciphisa/ukulawula ithrafikhi, uhlu olumnyama oluguquguqukayo, ukubhalisa/ukunciphisa izinga lokushaya ucingo njll. iyatholakala.
Izinkinga Zokuhambisana
Ukusebenzisana phakathi kwemikhiqizo ye-SIP akuqinisekisiwe ngaso sonke isikhathi. Ama-SBC enza ukuxhumana kube lula.
Q: Kungani kuvela izinkinga zokusebenzisana lapho wonke amadivayisi esekela i-SIP?
A: I-SIP iyindinganiso evulekile, abathengisi abahlukene bavame ukuba nezincazelo ezahlukene kanye nokusetshenziswa, okungabangela ukuxhumana kanye
/noma izinkinga zomsindo.
Q: I-SBC iyixazulula kanjani le nkinga?
A: Ama-SBC asekela ukwenziwa kwe-SIP kube ngokwejwayelekile ngomyalezo we-SIP kanye nokuphathwa kwekhanda. Ukuvezwa okuvamile kanye nokufakwa/ukususwa/ukuguqulwa okuhleliwe kuyatholakala kuma-Dinstar SBC.
Ama-SBC aqinisekisa ikhwalithi yesevisi (QoS)
Ukuphathwa kwezinhlelo eziningi kanye ne-multimedia kuyinkimbinkimbi. Umzila ojwayelekile wokuhambisa izinto
Kunzima ukubhekana nethrafikhi yemidiya ehlukahlukene, okubangela ukuminyana.
Hlaziya izingcingo zomsindo nezevidiyo, ngokusekelwe ekuziphatheni komsebenzisi. Ukulawula izingcingo
ukuphathwa: Umzila ohlakaniphile osekelwe kumuntu oshayela ucingo, amapharamitha e-SIP, isikhathi, i-QoS.
Uma inethiwekhi ye-IP ingazinzile, ukulahleka kwephakethe kanye nokubambezeleka kwe-jitter kubangela ikhwalithi embi
yenkonzo.
Ama-SBC aqapha ikhwalithi yocingo ngalunye ngesikhathi sangempela futhi athathe izinyathelo ezisheshayo
ukuqinisekisa i-QoS.
