Kutulutsidwa kwa Magma 1.2.0, nsanja yotumizira mwachangu ma network a LTE

Ipezeka kumasulidwa kwa nsanja Mphamvu ya 1.2.0, yokonzedwa kuti itumizidwe mofulumira kwa zigawo zothandizira 2G, 3G, 4G ndi 5G ma cellular network. Pulatifomu idapangidwa koyambirira ndi Facebook ngati gawo la zoyeserera kuti zitsimikizire kupezeka kwa maukonde padziko lonse lapansi, koma kenako kusinthidwa kukhala projekiti yosiyana yomwe idasamutsidwa mothandizidwa ndi bungwe lodziyimira pawokha lopanda phindu la OpenStack Foundation. Khodiyo idalembedwa mu C, C ++, Go ndi Python, ndi wogawidwa ndi pansi pa layisensi ya BSD.

Pulatifomu imapereka njira yatsopano yogwirira ntchito ya ogwiritsira ntchito telecom, pogwiritsa ntchito mapulogalamu otseguka ndikulola kuti pakhale mitundu yatsopano ya maukonde omwe amagwiritsa ntchito kusintha kwachangu komanso kusakanikirana kosalekeza kwa zigawo za mapulogalamu. Cholinga chachikulu cha chitukuko cha Magma chinali kuyesa kupanga nsanja yomanga maukonde amakono amakono, ogwirizana ndi zomwe zakhazikitsidwa kale pa LTE base station ndikuyendetsedwa pakati pazigawo zomwe zikuyenda pamtambo wachinsinsi kapena pagulu.

Pulatifomuyi imaperekanso zida zodzipangira zokha zomwe zimapangitsa kuyika maziko amsana kukhala kosavuta ngati kuyendetsa malo olowera pa Wi-Fi. Magma atha kugwiritsidwa ntchito molumikizana ndi ma network omwe alipo kale (LTE core network) kuti awonjezere magwiridwe antchito poyambitsa ntchito zatsopano ndikukonza mgwirizano wama network osiyanasiyana. Ndi Magma, ogwiritsa ntchito ma telecom omwe ali ndi zilolezo amatha kukulitsa kuchuluka kwa maukonde kapena kukulitsa kufalikira m'malo ovuta kufikako pogwiritsa ntchito Wi-Fi ndi Zamgululi. Mwachitsanzo, Magma imatha kufulumizitsa kutumizidwa kwa ma netiweki am'manja kumadera akumidzi, ndipo itha kugwiritsidwanso ntchito kupanga maukonde achinsinsi a LTE kapena mabizinesi opanda zingwe.

Magma imaphatikizanso zida zosinthira kutumizira ma netiweki, mapulogalamu oyang'anira ndi zida zapaintaneti kuti akonzekere kutumiza mapaketi. Kuti muchepetse zovuta pakuwongolera maukonde am'manja, Magma imapereka zida zosinthira, zosintha zamapulogalamu, komanso kuwonjezera zida zatsopano. Mawonekedwe otseguka a polojekitiyi amalola ogwira ntchito pa telecom kuti apange mayankho omwe sali omangika kwa wogulitsa zida m'modzi, amapereka kusinthasintha kwakukulu komanso kulosera, komanso amapereka mwayi wowonjezera ntchito zatsopano ndi ntchito.

Chinsinsi Zigawo Magma:

• AGW (Access Gateway) ndi njira yolowera yomwe imapereka kukhazikitsidwa kwa PGW (Packet Data Network Gateway), SGW (Serving Gateway), MME (Mobility Management Entity) ndi AAA (Authentication, Authorization and Accounting). Njira za SGW ndi mayendedwe amapaketi kupita kumasiteshoni oyambira. PGW imapereka kulumikizana kwa olembetsa kumanetiweki akunja, amasefa paketi ndi kulipira. MME imapereka kuyenda, kutsata mayendedwe olembetsa ndikuchita kusamuka pakati pa malo oyambira. AAA imapereka ntchito zapaintaneti pakutsimikizira, kuvomereza komanso kuwerengera ndalama zolembetsa. Kugwira ntchito ndi zida zomwe zilipo pamanetiweki am'manja zimathandizidwa.
• Federation Gateway ndi chipata chophatikizira ndi ma network oyambira ogwiritsira ntchito mafoni, pogwiritsa ntchito njira zolumikizirana za 3GPP kuti zigwirizane ndi zida zomwe zilipo kale. Imagwira ntchito ngati projekiti pakati pa Access Gateway (AGW) ndi netiweki ya othandizira, kupereka ntchito monga kutsimikizira, kulipiritsa, kuwerengera ndalama, ndikugwiritsa ntchito ziletso zamapulani.
• Orchestrator ndi ntchito yoyang'anira mitambo yokonza ndikuwunika ma netiweki opanda zingwe, kuphatikiza kusanthula magwiridwe antchito a netiweki ndikutsata mayendedwe amayendedwe. Mawonekedwe a intaneti amaperekedwa kuti aziwongolera. Orchestrator imatha kuthamanga m'malo okhazikika amtambo. Protocol imagwiritsidwa ntchito polumikizana ndi AGW ndi Federation Gateway gRPC, ikuyenda pamwamba pa HTTP/2.

M'kutulutsa kwatsopano:

• Zokonzedwanso kwambiri ndikukulitsidwa NMS (Network Management Station), mawonekedwe apaintaneti oyang'anira maukonde ndi kutumiza maukonde atsopano. Zambiri mu NMS tsopano zimafuna Elasticsearch.
  

• Pokhazikitsa chipata cha AGW (Access Gateway) munjira ya "Bridged Mode" chokulitsidwa njira zingapo zogawira ma adilesi a IP kwa ogwiritsa ntchito. Kugawa IP kuchokera padziwe, kugwiritsa ntchito DHCP, ndi static IP assignment zilipo. Adawonjezedwa zoyeserera pakuyendetsa ma APN-SGi angapo.
• Zowonjezedwa kuthandizira mbiri yamayendedwe amtundu wa ntchito (QoS) kuti akhazikitse mfundo zoletsa magalimoto. Zokonda za QoS zitha kukhazikitsidwa pa APN iliyonse yomwe imalola kulumikizana.
