• Yintoni uMlawuli weMida yeSeshini (SBC)
I-Session Border Controller (SBC) yinto yenethiwekhi esetyenziselwa ukukhusela iinethiwekhi ze-SIP ezisebenzisa ilizwi kwi-Internet Protocol (VoIP). I-SBC iye yaba ngumgangatho oqhelekileyo weenkonzo zefowuni kunye ne-multimedia ze-NGN / IMS.
| Iseshoni | Umda | Umlawuli |
| Unxibelelwano phakathi kwamaqela amabini. Olu luza kuba ngumyalezo wokubonisana wefowuni, isandi, ividiyo, okanye olunye ulwazi kunye nolwazi lwezibalo zefowuni kunye nomgangatho. | Indawo yokwahlulahlula phakathi kwenxalenye enye ye inethiwekhi kunye nenye. | Impembelelo abanayo abalawuli bomda weeseshoni kwimithombo yedatha equka iiseshoni ezinje ngokhuseleko, ukulinganisa, ulawulo lokufikelela, uthutho, isicwangciso, umqondiso, imidiya, i-QoS kunye nezixhobo zokuguqula idatha kwiifowuni abazilawulayo. |

• Kutheni udinga i-SBC
Imingeni ye-IP Telephony
| Iingxaki zoQhagamshelo | Iingxaki Zokuhambelana | Imiba yoKhuseleko |
| Akukho lizwi/lizwi elivela kwicala elinye elibangelwa yi-NAT phakathi kweenethiwekhi ezahlukeneyo. | Ngelishwa, ukusebenzisana phakathi kweemveliso ze-SIP zabathengisi abahlukeneyo akusoloko kuqinisekiswa. | Ukungena kweenkonzo, ukuphulaphulwa kweenkcukacha, ukwaliwa kokuhlaselwa kweenkonzo, ukuvalelwa kwedatha, ubuqhetseba kwiindlela zokuhlawula, iipakethi ze-SIP ezingalunganga ziya kubangela ilahleko enkulu kuwe. |
Iingxaki zoQhagamshelo
I-NAT iguqula i-IP yabucala ibe yi-IP yangaphandle kodwa ayikwazi ukutshintsha i-IP yomaleko wesicelo. Idilesi ye-IP yendawo ayilunganga, ngoko ke ayikwazi ukunxibelelana neendawo zokugqibela.
I-NAT Transversal
I-NAT iguqula i-IP yabucala ibe yi-IP yangaphandle kodwa ayikwazi ukutshintsha i-IP yomaleko wesicelo. I-SBC inokuyichonga i-NAT, itshintshe idilesi ye-IP ye-SDP. Ke ngoko ifumane idilesi ye-IP echanekileyo kwaye i-RTP inokufikelela kwiindawo zokugqibela.
Umlawuli weMida yeSession usebenza njengommeli wethrafikhi yeVoIP
Imiba yoKhuseleko
Ukhuseleko loHlaselo
Q: Kutheni kufuneka iSession Border Controller xa kuhlaselo lweVoIP?
A: Zonke iindlela zokuziphatha kwezinye iindlela zokuhlasela zeVoIP ziyahambelana neprotokholi, kodwa ezo ndlela zokuziphatha aziqhelekanga. Umzekelo, ukuba i-frequency yokufowuna iphezulu kakhulu, iya kubangela umonakalo kwisiseko sakho seVoIP. Ii-SBC zinokuhlalutya umaleko wesicelo kwaye zichonge iindlela zokuziphatha zomsebenzisi.
Ukhuseleko Lomthwalo Ogqithisileyo
Q: Yintoni ebangela ukuxinana kweemoto?
A: Iziganeko ezishushu zezona mithombo zixhaphakileyo zezizathu, ezifana nokuthenga kabini eTshayina (njengeBlack Friday eMelika), iziganeko ezinkulu, okanye uhlaselo olubangelwa ziindaba ezimbi. Ukwanda ngequbuliso kobhaliso okubangelwa kukusilela kwamandla kwiziko ledatha, ukusilela kwenethiwekhi kukwangumthombo oxhaphakileyo wezizathu.
Q: i-SBC ikuthintela njani ukugcwala kwezithuthi?
A: I-SBC inokucwangcisa iitrafikhi ngobuchule ngokwenqanaba lomsebenzisi kunye nokubaluleka kweshishini, ngokumelana okuphezulu kokugqithiswa: ukugqithiswa okuphindwe kathathu, ishishini aliyi kuphazanyiswa. Imisebenzi efana nokuncitshiswa/ulawulo lwetrafikhi, uluhlu olumnyama oluguqukayo, ubhaliso/ukuncitshiswa kwamaxabiso eefowuni njl.njl. ziyafumaneka.
Iingxaki Zokuhambelana
Ukusebenzisana phakathi kweemveliso ze-SIP akusoloko kuqinisekiswa. Ii-SBC zenza unxibelelwano lube mnandi.
Q: Kutheni kukho iingxaki zokusebenzisana xa zonke izixhobo zixhasa i-SIP?
A: I-SIP ngumgangatho ovulekileyo, abathengisi abahlukeneyo badla ngokuba neentsingiselo ezahlukeneyo kunye nokuphunyezwa, nto leyo enokubangela unxibelelwano kunye
/okanye iingxaki zesandi.
Q: I-SBC iyisombulula njani le ngxaki?
A: Ii-SBC zixhasa ukwenziwa kwe-SIP ngendlela eqhelekileyo ngokusebenzisa umyalezo we-SIP kunye nokuguqulwa kweentloko. Ukubonakaliswa rhoqo kunye nokongeza/ukucima/ukuguqula okucwangcisiweyo kuyafumaneka kwi-Dinstar SBCs.
Ii-SBC ziqinisekisa uMgangatho weNkonzo (QoS)
Ulawulo lweenkqubo ezininzi kunye nemultimedia luyinkimbinkimbi. Indlela eqhelekileyo yokuhambisa izinto
Kunzima ukujongana nethrafikhi yemultimedia, nto leyo ebangela ukuxinana.
Hlalutya iifowuni zesandi nezevidiyo, ngokusekelwe kwiindlela abasebenzisi abaziphethe ngayo. Ulawulo lweefowuni
ulawulo: Ulawulo olukrelekrele olusekelwe kumfowunayo, iiparameter ze-SIP, ixesha, i-QoS.
Xa inethiwekhi ye-IP ingazinzanga, ukulahleka kwepakethi kunye nokulibaziseka kwe-jitter kubangela umgangatho ombi
yenkonzo.
Ii-SBC zijonga umgangatho wefowuni nganye ngexesha langempela kwaye zithatha amanyathelo ngoko nangoko
ukuqinisekisa iQoS.
