Session Border Controller - Chinhu Chinokosha Chekushanda Kure
• Background
Munguva yekubuda kweCCIDID-19, kurudziro ye "social distancing" inomanikidza vazhinji vevashandi vemabhizinesi nemasangano kushanda kubva kumba (WFH).Nekuda kwehunyanzvi hwazvino, ikozvino zvave nyore kuti vanhu vashande kubva chero kupi kunze kwenzvimbo yechinyakare hofisi.Zviripachena, hakusi kungoda chete ikozvino, zvakare kweramangwana, sezvo makambani mazhinji kunyanya makambani einternet achibvumira vashandi kushanda kubva kumba uye kushanda zviri nyore.Nzira yekushandira pamwe kubva kupi zvako nenzira yakagadzikana, yakachengeteka uye inoshanda?
Matambudziko
IP telephony system ndiyo imwe nzira huru yekuti mahofisi ari kure kana vashandi-kubva-kumba vashandisi vabatane.Nekudaro, nekubatana kweinternet, kunouya akati wandei akakosha chengetedzo nyaya - yekutanga kuchengetedza zvakare SIP scanners inoedza kupinda mukati mekupedzisira-vatengi network.
Sezvo akawanda eIP telephony system vatengesi vakawanikwa, maSIP scanners anogona kuwana nekutanga kurwisa internet-yakabatana IP-PBXs mukati meawa yekushandiswa kwavo.Yakatangwa nevanobira pasi rese, maSIP scanner anogara achitsvaga zvisina kuchengetedzwa IP-PBX maseva aanogona kubira nekushandisa kutanga nhare dzehutsotsi.Chinangwa chavo ndechekushandisa IP-PBX yemunhu akabatwa kutanga mafoni kunhamba dzenhare dzepamusoro munyika dzisina kurongeka.Zvakakosha kudzivirira kubva kuSIP scanner uye dzimwe tambo.
Zvakare, kutarisana nekuoma kwema network akasiyana uye akawanda maSIP zvishandiso kubva kune vakasiyana vatengesi, iyo yekubatanidza nyaya inogara ichirwadza.Izvo zvakakosha kuti ugare pamhepo uye uone kuti vashandisi vefoni vari kure vanobatana pasina musono.
CASHLY chikamu chemuganho controller (SBC) yakanakira izvi zvinodiwa.
• Chii chinonzi Session Border Controller (SBC)
Session border controllers (SBCs) iri kumucheto kwenetiweki yebhizinesi uye inopa yakachengeteka izwi nevhidhiyo kubatana kune Session Initiation Protocol (SIP) trunk vanopa, vashandisi mumahofisi ebazi ari kure, vashandi vekumba / vashandi vari kure, uye kutaurirana kwakabatana sesevhisi. (UCaaS) vanopa.
Session, kubva kuSession Initiation Protocol, inoreva kushamwaridzana-nguva yekukurukurirana pakati pemagumo kana vashandisi.Iri rinowanzova izwi uye/kana vhidhiyo kufona.
Border, inoreva kuwirirana pakati pemanetiweki asina kuvimbana kuzere.
Controller, inoreva kugona kweSBC kutonga (kubvumira, kuramba, kushandura, kupera) chikamu chega chega chinodarika muganhu.
• Zvakanakira
• Kubatana
Vashandi vanoshanda vari kumba, kana kushandisa SIP client panhare mbozha yavo vanogona kunyoresa kuburikidza neSBC kuenda kuIP PBX, kuitira kuti vashandisi vashandise mahofisi avo ekuwedzera sekunge vakagara muhofisi.SBC iri kupa kure-kumagumo kutenderera kweNAT kumafoni ari kure pamwe nekuchengetedzwa kwakawedzerwa kune network yemakambani pasina chikonzero chekumisikidza VPN tunnel.Izvi zvichaita kuti kuseta kuve nyore, kunyanya panguva ino yakakosha.
• Chengetedzo
Network topology kuhwanda: MaSBC anoshandisa shandurudzo yenetiweki kero (NAT) padanho reOpen Systems Interconnection (OSI) Layer 3 Internet Protocol (IP) uye OSI Layer 5 SIP level kuchengetedza netiweki zvemukati zvakavanzwa.
Inzwi application firewall: SBCs inodzivirira kubva parunhare kurambwa kwesevhisi (TDoS) kurwiswa, kuparadzirwa kurambwa kwesevhisi (DDoS) kurwiswa, hutsotsi uye kuba sevhisi, kutonga kwekuwana, uye kuongorora.
Encryption: SBCs encrypt iyo siginecha uye midhiya kana iyo traffic ikapfuura emabhizinesi network neInternet vachishandisa Transport Layer Security (TLS) / Chengetedza Real-Nguva Yekufambisa Protocol (SRTP).
• Kushingirira
IP trunk load balancing: SBC inobatanidza kunzvimbo imwe chete pamusoro peinopfuura SIP trunk boka kuenzanisa mitoro yekufona zvakaenzana.
Alternative routing: nzira dzakawanda dzekuenda kunzvimbo imwe chete pamusoro peboka rimwechete reSIP trunk kukunda kuwandisa, kusawanikwa kwesevhisi.
Kuwanikwa kwepamusoro: 1 + 1 hardware redundancy inovimbisa bhizinesi rako kuenderera Kupindirana
• Kudyidzana
Transcoding pakati pemacodecs akasiyana uye pakati pemabitrate akasiyana (semuenzaniso, transcoding G.729 in enterprise network kuenda kuG.711 paSIP service provider network)
SIP normalization kuburikidza neSIP meseji uye musoro manipulation.Kunyangwe iwe uri kushandisa akasiyana vatengesi 'SIP zviteshi, hapazove nenyaya yekuenderana nerubatsiro rweSBC.
• WebRTC Gateway
Inobatanidza nzvimbo dzekugumisira dzeWebRTC kune dzisiri dzeWebRTC zvishandiso, sekufona kubva kuWebRTC mutengi kuenda kunhare yakabatana kuburikidza nePSTN.
CASHLY SBC chinhu chakakosha icho chaisakwanisa kufuratirwa mukushanda kure uye kushanda-kubva-kumba mhinduro, inovimbisa kubatana, chengetedzo uye kuwanikwa, inopa mukana wekuvaka yakagadzikana uye yakachengeteka IP telephony system kubatsira vashandi kushandira pamwe kunyangwe ivo. vari munzvimbo dzakasiyana.
Gara wakabatana, uchishanda kumba, shandira pamwe zvakanyanya.
