Yintoni umlawuli weseshini yomsebenzi (SBC)
Umlawuli weSeshini (i-SBC) yinkanuko yenethiwekhi ekuthunyelwe ukukhusela ilizwi elisekwe kwi-SIP kwi-Intanethi yomgaqo we-Intanethi (VIIP). I-SBC iye yaba ngumgangatho we-de-facto yefowuni yefowuni kunye neenkonzo zemultimedia ze-NGN / IMS.

Oku kunokuba ngumyalezo osayiniweyo, umsindo, ividiyo, okanye enye idatha kunye nolwazi lweenkcukacha-manani kunye nomgangatho. | Inqaku lokucandwa kwenxalenye nganye ye Inethiwekhi kunye nenye. | Impembelelo ekuthintelwa ngemisitho yemidlalo yeseshoni ineeseshini zokuthatha iiseshoni zokhuseleko njengokhuseleko, ulawulo lokufikelela, ukuhambisa, iziseko zonxibelelwano, i-QOS kunye nedatha yokuguqula abalawulayo. |

Imicimbi yoNxibelelwano
I-Nat iguqula i-IP yabucala kwi-IP yangaphandle kodwa ayikwazi ukuguqula i-IP ye-IP. Idilesi ye-IP ye-IP ayilunganga, ngenxa yoko ayikwazi ukunxibelelana neziphelo.
Nat themba
I-Nat iguqula i-IP yabucala kwi-IP yangaphandle kodwa ayikwazi ukuguqula i-IP ye-IP. I-SBC inokuchonga i-Nat, iguqule idilesi ye-SDP. Ke ngoko idilesi ye-IP echanekileyo kunye ne-RTP inokufikelela kwiindawo zokugqibela.

Imiba yezokhuseleko
Ukhuseleko lokuhlasela
Q: Kutheni umlawuli wesesi semvelaphi uyafuneka kwi-voip uhlaselo?
A: Zonke iindlela zokuziphatha ezihlanyeneyo zihambisa iprotocol, kodwa indlela yokuziphatha ingaqhelekanga. Umzekelo, ukuba i-frequency yefowuni iphezulu kakhulu, iya kubangela ukonakala kwiziseko zakho zeVOIP. Ii-SBCs zihlalutya ungqimba lwesicelo kwaye ichonge indlela yokuziphatha yomsebenzisi.
Ukhuseleko ngaphezulu
Q: Yintoni ebangela ukugcwala kwezithuthi?
AIminyhadala eshushu yeyona mithombo ixhaphakileyo ye-trigger, njengokuthenga i-11 ivenkile e-China (njengowesihlanu omnyama e-USA), imicimbi eninzi, okanye uhlaselo olungelwe ziindaba ezimbi. Ukupheliswa ngesiquphe kobhaliso olubangelwa kukungapheli kwamandla edatha, ukusilela kwenethiwekhi kukwangumthombo oqhelekileyo.
Q: I-SBC inqanda njani ukugcwala kwezithuthi?
A: I-SBC inokuhlela i-Traffics ngengqondo yenqanaba lomsebenzisi kunye neshishini eliphambili, ngokuchasana okuphezulu: Ukulayisha ixesha eli-3, ishishini alizukuphazamiseka. Imisebenzi njengokuncitshiswa kweendlela / ukulawula, uluhlu olungenakukhanya, ubhaliso / ukunqunyulwa kwereyitha, njlnjl.
Imiba yokuhambelana
Ukusebenzisana phakathi kweemveliso ze-SIP akusoloko kuqinisekisiwe. Ii-SBCs zenza ukuba i-uqhagamshelo alunamthungo.
Q: Kutheni le nto imicimbi yenziwa yimicimbi yokuhlangana yenzeka xa zonke izixhobo zixhasa i-SIP?
A: I-SIP ngumgangatho ovulekileyo, abathengisi abahlukeneyo bahlala betolika ngeendlela kunye nokuphumeza, ezinokubangela unxibelelwano kwaye
/ okanye imiba yeaudio.
Q: I-SBC isombulula njani le ngxaki?
A: I-A: SBCS ixhasa i-SIP ye-SIP ye-SIP yomyalezo we-SIP kunye nentloko yentloko. Inkcazo eqhelekileyo kunye nokongezwa kwenkqubo / ukucima / ukuguqula kuyafumaneka kwii-SBCs ezidino.
I-SBCS iqinisekisa umgangatho weenkonzo (QOS)
Ulawulo lweenkqubo ezininzi kunye nemultimedia inzima. Ukuqhekeza okuqhelekileyo
Kunzima ukujongana nezithuthi zemultimedia, okukhokelela ekuxinisweni.
Hlalutya iifowuni zeaudio kunye nevidiyo, esekwe ekuziphatheni umsebenzisi.Call
Ulawulo: Ukuphakama kwengqondo ngokusekwe kwi-Buffer, iparamitha ye-SIP, ixesha, Qos.
Xa inethiwekhi ye-IP ayizinzanga, ilahleko yepakethi kunye nokulibaziseka kwe-jitter kubangela umgangatho ombi
yenkonzo.
I-SBCS ibeka esweni umgangatho womnxeba ngamnye ngexesha lokwenyani kwaye uthathe amanyathelo ngokukhawuleza
Ukuqinisekisa i-qos.
