• Chii chinonzi Session Border Controller (SBC)?
Session Border Controller (SBC) chinhu chenetwork chinoshandiswa kuchengetedza ma SIP based voice over Internet Protocol (VoIP) networks. SBC yave ndiyo standard ye NGN / IMS telephony uye multimedia services.

Matambudziko ekubatana
NAT inoshandura private IP kuita external IP asi haigone kugadzirisa application layer IP. Destination IP address haisiyo, saka haigone kutaurirana nema endpoints.
NAT Transversal
NAT inoshandura private IP kuita external IP asi haigone kugadzirisa application layer IP. SBC inogona kuziva NAT, kugadzirisa IP address yeSDP. Saka kuwana IP address chaiyo uye RTP inogona kusvika kuma endpoints.
Session Border Controller inoshanda semumiririri weVoIP traffics

Dziviriro yeKurwiswa
Mubvunzo: Sei Session Border Controller ichidikanwa pakurwiswa kweVoIP?
A: Maitiro ese emamwe maVoIP anoitwa anotevedzera protocol, asi maitiro acho haana kujairika. Semuenzaniso, kana frequency yekufona yakanyanya, ichakonzera kukuvara kweVoIP yako. MaSBC anogona kuongorora application layer uye kuona maitiro evashandisi.
Dziviriro Yekuremerwa Zvakawandisa
QChii chinokonzera kuwandisa kwemotokari?
A: Zviitiko zvinopisa ndizvo zvinonyanya kukonzera matambudziko, zvakaita sekutenga zvinhu zviviri muChina (seBlack Friday muUSA), zviitiko zvevanhu vakawanda, kana kurwiswa kunokonzerwa nenhau dzisina kunaka. Kuwedzera kwekunyoresa kunokonzerwa nekukundikana kwemagetsi enzvimbo yedata, kukundikana kwenetwork inyaya inowanzo kukonzera matambudziko.
Q: SBC inodzivirira sei kuwandisa kwemotokari?
A: SBC inogona kuronga vanhu vanofamba nepagedhi nenzira yekuchenjera zvichienderana nedanho remushandisi uye kukosha kwebhizinesi, nekuramba kuwanda kwehuwandu hwezvinhu: kuwanda kwehuwandu katatu, bhizinesi harizovhiringidzwi. Mabasa akadai sekudzora/kudzora traffic, dhijitari yedhijitari, kunyoresa/kudzora mwero wekufona nezvimwewo zviripo.
Matambudziko Ekubatana
Kushanda pamwe chete pakati pezvigadzirwa zveSIP hakuvimbiswi nguva dzose. MaSBC anoita kuti kubatana kuenderane zvakanaka.
Mubvunzo: Sei paine matambudziko ekushanda pamwe chete kana zvishandiso zvese zvichitsigira SIP?
A: SIP imhando yakavhurika, vatengesi vakasiyana vanowanzova nedudziro dzakasiyana uye mashandisirwo, izvo zvinogona kukonzera kubatana uye
/kana matambudziko eruzha.
Mubvunzo: SBC inogadzirisa sei dambudziko iri?
A: MaSBC anotsigira kurongeka kweSIP kuburikidza neshoko reSIP uye kugadziriswa kwemusoro. Kuratidzwa kwakajairika uye kuwedzera/kubvisa/kugadzirisa zvinorongwa zviripo muDinstar SBCs.
MaSBC anovimbisa Hunhu hweBasa (QoS)
Kutungamirirwa kwemasisitimu akasiyana-siyana uye multimedia kwakaoma. Kuronga nzira kwakajairika
Zvakaoma kubata ne multimedia traffic, zvichikonzera kuwanda kwevanhu.
Ongorora mafoni eruzha nemavhidhiyo, zvichibva pane maitiro emushandisi. Kudzora mafoni
manejimendi: Kufambisa kwakangwara kwakavakirwa pane munhu anofona, maparamita eSIP, nguva, QoS.
Kana network yeIP isina kugadzikana, kurasikirwa kwepaketi uye kunonoka kwe jitter kunokonzera hunhu husina kunaka
yebasa.
Makambani eSBC anoongorora mhando yekufona kwega kwega panguva chaiyo uye anotora matanho nekukasika
kuve nechokwadi chekuti QoS.
