Ukukhutshwa kwe-Magma 1.2.0, iqonga lokusasazwa ngokukhawuleza kothungelwano lwe-LTE

Iyafumaneka ukukhululwa kweqonga IMagma 1.2.0, eyenzelwe ukuthunyelwa ngokukhawuleza kwamacandelo ukuxhasa i-2G, 3G, 4G kunye ne-5G iinethiwekhi zeselula. Iqonga laphuhliswa ekuqaleni nguFacebook njengenxalenye ye amalinge ukuqinisekisa ukufikeleleka kwenethiwekhi yehlabathi, kodwa emva koko iguqulwe ibe yiprojekthi eyahlukileyo edluliselwe phantsi kombutho ozimeleyo ongenzi nzuzo i-OpenStack Foundation. Ikhowudi ibhalwe kwiC, C ++, Hamba kunye nePython, kunye isasazwa ngu phantsi kwelayisensi ye-BSD.

Iqonga linikeza indlela entsha yomsebenzi wabaqhubi be-telecom, ngokusekelwe ekusebenziseni isofthiwe evulekileyo kunye nokuvumela ukudalwa kweentlobo ezintsha zenethiwekhi ezisebenzisa umjikelezo wokuhlaziya ngokukhawuleza kunye nokuhlanganiswa okuqhubekayo kwamacandelo esofthiwe. Eyona njongo iphambili yophuhliso lweMagma yayikukuzama ukwenza iqonga lokwakha uthungelwano olusebenzayo lwale mihla, oluhambelana nokuphunyezwa kwesiseko sesikhululo se-LTE esikhoyo kunye nokulawulwa kumbindi kusetyenziswa amacandelo asebenza kwindawo zabucala okanye zikawonke-wonke.

Iqonga libonelela ngezixhobo ezizenzekelayo ezenza ukuthunyelwa kweziseko zomqolo kube lula njengokuqhuba indawo yokufikelela kwi-Wi-Fi. I-Magma inokusetyenziswa ngokubambisana nothungelwano olungundoqo olukhoyo (i-LTE core network) ukwandisa ukusebenza kwabo malunga nokuqaliswa kweenkonzo ezintsha kunye nokuququzelela umanyano lothungelwano olwahlukeneyo. Nge-Magma, abaqhubi be-telecom abakhawulelwe yi-spectrum enelayisensi banokwandisa umthamo wenethiwekhi okanye banyuse ukhuseleko kwiindawo ekunzima ukufikelela kuzo besebenzisa i-Wi-Fi kunye I-CBRS. Umzekelo, iMagma inokukhawulezisa ukuthunyelwa kweenethiwekhi zeselula kwiindawo ezisemaphandleni, kwaye ingasetyenziselwa ukwenza iinethiwekhi zabucala ze-LTE okanye iinkqubo ezingenazingcingo zeshishini.

I-Magma ibandakanya izixhobo zokwenza ukuhanjiswa kwenethiwekhi ngokuzenzekelayo, isoftware yolawulo kunye namacandelo enethiwekhi angundoqo ukuququzelela ukuhanjiswa kwepakethi. Ukunciphisa ukuntsonkotha kokulawula iinethiwekhi eziphathwayo, iMagma ibonelela ngezixhobo zokuzenzela uqwalaselo, uhlaziyo lwesoftware, kunye nokongezwa kwezixhobo ezitsha. Ubume obuvulekileyo beprojekthi buvumela abaqhubi be-telecom ukuba benze izisombululo ezingaboshelwanga kumthengisi omnye wezixhobo, zibonelela ngokuguquguquka okukhulu kunye nokuqikelelwa, kwaye zibonelela ngamathuba amaninzi okongeza iinkonzo ezintsha kunye nezicelo.

Isitshixo Izixhobo Makhulu:

• I-AGW (iSango lokuFikelela) lisango lokufikelela elibonelela ngokuphunyezwa kwePGW (iPacket Data Network Gateway), iSGW (iSango lokuSebenza), iMME (iZiko loLawulo lokuHamba) kunye ne-AAA (uQinisekiso, uGunyaziso kunye noXanduva). Iinkqubo ze-SGW kunye neepakethe zeendlela ukuya kwizikhululo ezisisiseko. I-PGW ibonelela ngoqhagamshelwano lomrhumi kuthungelwano lwangaphandle, yenza ukuhluza ipakethi kunye nokuhlawula. I-MME ibonelela ngokushukumiseka, ilandelela intshukumo yababhalisi kwaye yenza imfuduko phakathi kwezikhululo ezisisiseko. I-AAA inikezela ngeenkonzo zenethiwekhi zokuqinisekisa, ukugunyaziswa kunye nokubhaliswa kwababhalisi. Ukusebenza kunye nezixhobo ezikhoyo zothungelwano lweselula ziyaxhaswa.
• I-Federation Gateway lisango lokudibanisa kunye nenethiwekhi engundoqo yabaqhubi beselula, usebenzisa i-interfaces esemgangathweni ye-3GPP ukusebenzisana namacandelo enethiwekhi ekhoyo. Isebenza njengommeli phakathi kwe-Access Gateway (AGW) kunye nothungelwano lomthwali, ibonelela ngemisebenzi efana nokuqinisekiswa, ukuhlawulisa, ukugcinwa kwengxelo, kunye nokusebenzisa izithintelo zesicwangciso sentlawulo.
• I-Orchestrator yinkonzo yokulawula ifu yokuqwalasela nokubeka iliso kwinethiwekhi engenazintambo, kuquka ukuhlalutya ukusebenza kwenethiwekhi kunye nokulandelela ukuhamba kwezithuthi. Ujongano lwewebhu lunikezelwa kulawulo. IOkhestra inokubaleka kwiindawo ezisemgangathweni zamafu. Iprotocol isetyenziselwa ukusebenzisana ne-AGW kunye ne-Federation Gateway I-GRPC, esebenza phezu kwe-HTTP/2.

Kukhupho olutsha:

• Uyilwe ngokutsha kwaye wandiswa ngokuphawulekayo I-NMS (ISikhululo soLawulo lweNethiwekhi), ujongano lwewebhu lokulawula uthungelwano kunye nokuhambisa amanethiwekhi amatsha. Iimpawu ezininzi kwi-NMS ngoku zifuna i-Elasticsearch.
  

• Ekuphunyezweni kwe-AGW (iSango lokuFikelela) isango lokungena kwimo ye "Bridged Mode" yandisiwe inani lezicwangciso zokunikezelwa kweedilesi ze-IP kubasebenzisi. Ukwabiwa kwe-IP ukusuka echibini, usebenzisa i-DHCP, kunye ne-static assignment ye-IP iyafumaneka. Inkxaso yovavanyo eyongeziweyo yokusebenzisa i-APN-SGi ezininzi.
• Yongeziwe inkxaso yomgangatho wenkonzo yesiko (QoS) iiprofayili zolawulo lokumisela imigaqo-nkqubo yothintelo lwendlela. Useto lweQoS lunokuqwalaselwa kwi-APN nganye evumela uxhulumaniso.
