• Yini iSession Border Controller(SBC)
I-Session Border Controller(SBC) iyingxenye yenethiwekhi esetshenziselwa ukuvikela izwi elisuselwa ku-SIP ngamanethiwekhi e-Internet Protocol(VoIP).I-SBC isiphenduke indinganiso ye-de-facto yezinsizakalo zocingo kanye ne-multimedia ye-NGN / IMS.

Izinkinga zokuxhumana
I-NAT ishintsha i-IP eyimfihlo ibe yi-IP yangaphandle kodwa ayikwazi ukushintsha i-IP yesendlalelo sohlelo lokusebenza.Ikheli le-IP okuyiwa kulo alilungile, ngakho-ke alikwazi ukuxhumana namaphoyinti okugcina.
I-NAT Transversal
I-NAT ishintsha i-IP eyimfihlo ibe yi-IP yangaphandle kodwa ayikwazi ukushintsha i-IP yesendlalelo sohlelo lokusebenza.I-SBC ingakwazi ukuhlonza i-NAT, iguqule ikheli le-IP le-SDP.Ngakho-ke thola ikheli le-IP elilungile futhi i-RTP ingafinyelela ekugcineni.
Isilawuli Session Border sisebenza njengommeleli we-VoIP traffics
Izinkinga Zokuphepha
Ukuvikela Ukuhlasela
Q: Kungani Isilawuli Session Border sidingeka ekuhlaselweni kwe-VoIP?
IMP: Konke ukuziphatha kokunye ukuhlaselwa kwe-VoIP kuhambisana nephrothokholi, kodwa ukuziphatha akujwayelekile.Isibonelo, uma ifrikhwensi yocingo iphezulu kakhulu, izodala umonakalo kungqalasizinda yakho ye-VoIP.Ama-SBC angahlaziya isendlalelo sohlelo lokusebenza futhi akhombe ukuziphatha komsebenzisi.
Ukuvikelwa kokulayisha ngokweqile
Q: Yini edala ukugcwala kwezimoto?
A: Imicimbi eshisayo iyimithombo evame kakhulu yokuqalisa, njengokuthenga kabili okungu-11 e-China (njengoLwesihlanu Olumnyama e-USA), izehlakalo ezinkulu, noma ukuhlaselwa okubangelwa izindaba ezingezinhle.Ukubhaliswa okungazelelwe okubangelwa ukwehluleka kwamandla esikhungo sedatha, ukwehluleka kwenethiwekhi nakho kuwumthombo ovamile wokubangela.
Q: i-SBC ikuvimbela kanjani ukugcwala kwethrafikhi?
A: I-SBC ingakwazi ukuhlunga ithrafikhi ngobuhlakani ngokuya ngeleveli yomsebenzisi kanye nokubalulekile kwebhizinisi, ngokumelana nokugcwala okuphezulu: ukugcwala okuphindwe izikhathi ezi-3, ibhizinisi ngeke liphazamiseke.Imisebenzi efana nomkhawulo/ukulawula kwethrafikhi, uhlu oluvinjelwe olushintshashintshayo, ukubhaliswa/ukunciphisa izinga lokushaya njll. iyatholakala.
Izinkinga zokuhambisana
Ukusebenzisana phakathi kwemikhiqizo ye-SIP akuqinisekisiwe njalo.Ama-SBC enza ukuxhumana kungabi namthungo.
Q: Kungani izinkinga zokusebenzisana zenzeka lapho wonke amadivayisi asekela i-SIP?
A: I-SIP iyindinganiso evulekile, abathengisi abahlukene bavame ukuba nezincazelo ezahlukene kanye nokusebenza, okungabangela uxhumano kanye
/noma izinkinga zomsindo.
Umbuzo: I-SBC iyixazulula kanjani le nkinga?
A: Ama-SBC asekela ukwenziwa kwe-SIP kujwayelekile ngomlayezo we-SIP nokukhohlisa kwesihloko.Izisho ezivamile kanye nokwengeza/ukususa/ukulungisa okulungisekayo kuyatholakala kuma-SBC e-Dinstar.
Ama-SBC aqinisekisa Ikhwalithi Yesevisi (QoS)
Ukuphatha amasistimu amaningi kanye ne-multimedia kuyinkimbinkimbi.Umzila ojwayelekile
Kunzima ukubhekana ne-multimedia traffic, okuholela ekuminyana.
Hlaziya amakholi omsindo nevidiyo, ngokusekelwe ekuziphatheni komsebenzisi.Ukulawula ikholi
ukuphathwa: Umzila ohlakaniphile osuselwe kumshayi ucingo, amapharamitha we-SIP, isikhathi, i-QoS.
Uma inethiwekhi ye-IP ingazinzile, ukulahleka kwephakethe nokubambezeleka kwe-jitter kubangela ikhwalithi embi
yenkonzo.
Ama-SBC aqapha ikhwalithi yocingo ngalunye ngesikhathi sangempela futhi athathe izinyathelo ezisheshayo
ukuqinisekisa QoS.
