Ukukhishwa kwe-Magma 1.2.0, inkundla yokuthunyelwa ngokushesha kwamanethiwekhi e-LTE

Iyatholakala ukukhululwa kwesikhulumi Ngo-1.2.0, eyenzelwe ukuthunyelwa okusheshayo kwezingxenye zokusekela amanethiwekhi weselula we-2G, 3G, 4G kanye ne-5G. Inkundla yasungulwa yi-Facebook njengengxenye ye imizamo ukuze kuqinisekiswe ukufinyeleleka kwenethiwekhi yomhlaba wonke, kodwa bese iguqulwa ibe iphrojekthi ehlukile edluliselwe ngaphansi kwenhlangano ezimele engenzi nzuzo i-OpenStack Foundation. Ikhodi ibhalwe ku-C, C++, Go kanye nePython, kanye isatshalaliswa ngu ngaphansi kwelayisensi ye-BSD.

Isiteji sinikeza indlela entsha yomsebenzi wabaqhubi be-telecom, ngokusekelwe ekusetshenzisweni kwesofthiwe evulekile nokuvumela ukudalwa kwezinhlobo ezintsha zamanethiwekhi asebenzisa umjikelezo wokuvuselela okusheshayo nokuhlanganiswa okuqhubekayo kwezingxenye zesofthiwe. Umgomo oyinhloko wokuthuthukiswa kwe-Magma kwakuwukuzama ukwakha inkundla yokwakha amanethiwekhi eselula esimanje asebenza kahle, ahambisana nokusetshenziswa kwesiteshi sesisekelo se-LTE esikhona futhi esiphethwe maphakathi kusetshenziswa izingxenye ezisebenza ezindaweni eziyimfihlo noma zomphakathi.

Inkundla iphinde ihlinzeke ngamathuluzi okuzenzakalela enza ukuthunyelwa kwengqalasizinda yomgogodla kube lula njengokusebenzisa indawo yokufinyelela ye-Wi-Fi. I-Magma ingasetshenziswa ngokuhambisana namanethiwekhi akhona endabuko (inethiwekhi eyinhloko ye-LTE) ukuze kwandiswe ukusebenza kwawo mayelana nokwethulwa kwezinsizakalo ezintsha nokuhlela umfelandawonye wamanethiwekhi ahlukene. Nge-Magma, ama-telecom opharetha anomkhawulo nge-spectrum enamalayisense anganweba umthamo wenethiwekhi noma akhuphule ukutholakala ezindaweni okunzima ukufinyelela kuzo kusetshenziswa i-Wi-Fi kanye I-CBRS. Isibonelo, i-Magma ingasheshisa ukuthunyelwa kwamanethiwekhi omakhalekhukhwini ezindaweni zasemakhaya, futhi ingase isetshenziselwe ukudala amanethiwekhi ayimfihlo e-LTE noma amasistimu angenawaya ebhizinisi.

I-Magma ihlanganisa amathuluzi okwenza ngokuzenzakalelayo ukuthunyelwa kwenethiwekhi, isofthiwe yokuphatha kanye nezingxenye eziyinhloko zenethiwekhi ukuhlela ukulethwa kwamaphakethe. Ukuze kuncishiswe inkimbinkimbi yokuphatha amanethiwekhi eselula, i-Magma inikeza amathuluzi okwenza ukucushwa okuzenzakalelayo, ukubuyekezwa kwesofthiwe, nokwengezwa kwamadivayisi amasha. Imvelo evulekile yephrojekthi ivumela opharetha be-telecom ukuthi benze izixazululo ezingaboshiwe kumhlinzeki oyedwa wemishini, inikeza ukuguquguquka okukhulu nokubikezela, futhi inikeza namathuba amaningi okwengeza izinsizakalo ezintsha nezinhlelo zokusebenza.

Ukhiye Izingxenye Magma:

• I-AGW (Isango Lokufinyelela) isango lokufinyelela elihlinzeka ngokusetshenziswa kwe-PGW (Packet Data Network Gateway), SGW (Serving Gateway), MME (Mobility Management Entity) kanye ne-AAA (Ukuqinisekisa, Ukugunyazwa nokubalwa kwezimali). I-SGW icubungula futhi ihambisa amaphakethe eziteshini eziyisisekelo. I-PGW ihlinzeka ngokuxhumeka kobhalisile kumanethiwekhi angaphandle, yenza ukuhlunga kwephakethe nokukhokhisa. I-MME inikeza ukuhamba, ilandelela ukunyakaza kwababhalisile futhi yenza ukufuduka phakathi kweziteshi eziyisisekelo. I-AAA ihlinzeka ngezinsizakalo zenethiwekhi zokuqinisekisa, ukugunyazwa nokubalwa kwababhalisi. Ukusebenza ngemishini ekhona yamanethiwekhi weselula kuyasekelwa.
• I-Federation Gateway iyisango lokuhlanganiswa nenethiwekhi ewumgogodla yama-opharetha eselula, kusetshenziswa ukuxhumana okujwayelekile kwe-3GPP ukuze kuhlanganyele nezingxenye zenethiwekhi ezikhona. Isebenza njengommeleli phakathi kwe-Access Gateway (AGW) nenethiwekhi yenkampani yenethiwekhi, ihlinzeka ngemisebenzi efana nokuqinisekisa, ukushaja, ukubalwa kwezimali, nokusebenzisa imikhawulo yohlelo lwentela.
• I-Orchestrator iyisevisi yokuphatha yamafu yokulungisa nokuqapha inethiwekhi engenantambo, okuhlanganisa ukuhlaziya ukusebenza kwenethiwekhi nokulandelela ukugeleza kwethrafikhi. Isixhumi esibonakalayo sewebhu sinikezwa ukuphathwa. I-Orchestrator ingagijima ezindaweni ezijwayelekile zamafu. Iphrothokholi isetshenziselwa ukuxhumana ne-AGW kanye ne-Federation Gateway gRPC, isebenza phezu kwe-HTTP/2.

Ekukhishweni okusha:

• Iklanywe kabusha ngokuphawulekayo futhi yanwetshwa NMS (Isiteshi Sokuphathwa Kwenethiwekhi), isixhumi esibonakalayo sewebhu sokuphatha amanethiwekhi nokukhipha amanethiwekhi amasha. Izici eziningi ku-NMS manje zidinga i-Elasticsearch.
  

• Ekusetshenzisweni kwesango lokufinyelela le-AGW (Access Gateway) kumodi "yemodi yebhuloho" kunwetshiwe inani lamasu okunikeza amakheli e-IP kubasebenzisi. Ukwaba i-IP kusuka endaweni yokubhukuda, kusetshenziswa i-DHCP, kanye nokwabiwa kwe-IP emile kuyatholakala. Kwengezwe usekelo lokuhlola lokusebenzisa i-APN-SGi eminingi.
• Kwengeziwe ukwesekwa kwephrofayili yokuphatha ikhwalithi yesevisi yangokwezifiso (QoS) ukuze kusethwe izinqubomgomo zokukhawulelwa kwethrafikhi. Izilungiselelo ze-QoS zingalungiselelwa i-APN ngayinye evumela ukuxhumana.
