• Yintoni uMlawuli weBorder yeSeshini(SBC)
IsiLawuli soMda weSeshini (SBC) sisixhobo sothungelwano esimiselwe ukukhusela ilizwi elisekelwe kwi-SIP kuthungelwano lweProtokholi ye-Intanethi (VoIP).I-SBC iye yaba ngumgangatho we-de-facto kwinkonzo yomnxeba kunye nemultimedia ye-NGN / IMS.
| Iseshoni | Umda | Umlawuli |
| Unxibelelwano phakathi kwamaqela amabini.Oku kuya kuba ngumyalezo womqondiso womnxeba, iaudio, ividiyo, okanye enye idata kunye nolwazi lweenkcukacha manani kunye nomgangatho. | Indawo yomda phakathi kwendawo enye inethiwekhi kunye nenye. | Impembelelo yokuba iseshoni abalawuli bemida banalo kwimithombo yedatha equka iiseshoni ezinjengokhuseleko, ukulinganisa, ukulawula ukufikelela, umzila, isicwangciso, ukubonakaliswa, imidiya, i-QoS kunye nezixhobo zokuguqulwa kwedatha kwiifowuni abazilawulayo. |

• Kutheni ufuna i-SBC
Imingeni ye-IP Telephony
| Imiba yoQhagamshelwano | Imiba yokuhambelana | Imiba yoKhuseleko |
| Akukho lizwi / ilizwi lendlela enye elibangelwa yi-NAT phakathi kwe-sub-network ezahlukeneyo. | Ukusebenzisana phakathi kweemveliso ze-SIP zabathengisi abahlukeneyo ngelishwa akusoloko kuqinisekisiwe. | Ukungena kweenkonzo, ukuphulaphula, ukwaliwa kohlaselo lwenkonzo, uthintelo lwedatha, ubuqhophololo berhafu, iipakethi ezingalunganga ze-SIP zinokubangela ilahleko enkulu kuwe. |
Imiba yoQhagamshelwano
I-NAT iguqula i-IP yabucala kwi-IP yangaphandle kodwa ayikwazi ukulungisa umaleko wesicelo se-IP.Idilesi ye-IP yendawo ayilunganga, ngenxa yoko ayikwazi ukunxibelelana neendawo zokuphela.
I-NAT Transversal
I-NAT iguqula i-IP yabucala kwi-IP yangaphandle kodwa ayikwazi ukulungisa umaleko wesicelo se-IP.I-SBC inokuchonga i-NAT, iguqule idilesi ye-IP ye-SDP.Ke ngoko fumana idilesi ye-IP echanekileyo kwaye i-RTP inokufikelela kwiisiphelo.
Umlawuli weSeshini yeBorder usebenza njengommeli weVoIP traffics
Imiba yoKhuseleko
Ukukhuselwa kuHlaselo
Umbuzo: Kutheni iSession Border Controller ifuneka kuhlaselo lweVoIP?
A: Zonke iindlela zokuziphatha zolunye uhlaselo lweVoIP luhambelana neprotocol, kodwa ukuziphatha okungaqhelekanga.Umzekelo, ukuba i-frequency yefowuni iphezulu kakhulu, iya kubangela umonakalo kwisiseko sakho seVoIP.Ii-SBC zinokuhlalutya umaleko wesicelo kwaye zichonge ukuziphatha komsebenzisi.
uKhuseleko lomthwalo ogqithisileyo
Q: Yintoni ebangela ukugcwala kwetrafikhi?
A: Iziganeko ezishushu ziyimithombo ye-trigger eqhelekileyo, njenge-double 11 yokuthenga e-China (njenge-Black Friday e-USA), iziganeko ezininzi, okanye ukuhlaselwa okubangelwa iindaba ezimbi.Ukunyuka ngokukhawuleza kokubhaliswa okubangelwa ukusilela kwamandla kwiziko ledatha, ukungaphumeleli kwenethiwekhi kukwangumthombo oqhelekileyo wokubangela.
Q: ingaba iSBC ikuthintela njani ukugcwala kwetrafikhi?
A: I-SBC inokuhlela iitrafikhi ngobukrelekrele ngokwenqanaba lomsebenzisi kunye nokubaluleka kweshishini, kunye nokuchasana nokugcwala okuphezulu: amaxesha ama-3 ukugcwala, ishishini aliyi kuphazanyiswa.Imisebenzi efana nokunciphisa i-traffic/ulawulo, uluhlu oluvaliweyo oluguquguqukayo, ubhaliso/ukunciphisa izinga lokufowuna njl njl.
Imiba yokuhambelana
Ukusebenzisana phakathi kweemveliso ze-SIP akusoloko kuqinisekisiwe.Ii-SBC zenza uqhagamshelo lungabinamthungo.
Umbuzo: Kutheni imiba yokusebenzisana isenzeka xa zonke izixhobo zixhasa i-SIP?
A: I-SIP ngumgangatho ovulekileyo, abathengisi abahlukeneyo bahlala beneendlela ezahlukeneyo zokutolika kunye nokuphunyezwa, okunokubangela uxhulumaniso kunye
/ okanye imiba yomsindo.
Umbuzo: Ingaba iSBC iyisombulula njani le ngxaki?
A: Ii-SBCs zixhasa uhlengahlengiso lwe-SIP ngomyalezo we-SIP kunye nokukhohlisa kwentloko.Ukuchazwa okuqhelekileyo kunye nokudibanisa okucwangcisekileyo / ukucima / ukulungiswa kuyafumaneka kwi-Dinstar SBCs.
Ii-SBCs ziqinisekisa uMgangatho weNkonzo (QoS)
Ulawulo lweenkqubo ezininzi kunye nemultimedia inzima.Indlela eqhelekileyo
Kunzima ukujongana netrafikhi yemultimedia, okukhokelela kwingxinano.
Hlalutya iifowuni zesandi kunye nevidiyo, ngokusekelwe kwindlela yokuziphatha yabasebenzisi.Ulawulo lokufowuna
Ulawulo:Umgaqo okrelekrele usekwe kumnxeba, iiparamitha ze-SIP, ixesha, iQoS.
Xa inethiwekhi ye-IP ingazinzanga, ukulahleka kwepakethi kunye nokulibaziseka kwe-jitter kubangela umgangatho ombi
yenkonzo.
Ii-SBCs zijonga umgangatho womnxeba ngamnye ngexesha lokwenyani kwaye zithathe amanyathelo akhawulezileyo
ukuqinisekisa iQoS.
