Ntọhapụ nke Magma 1.2.0, ikpo okwu maka mbugharị ngwa ngwa nke netwọkụ LTE

Dị ntọhapụ ikpo okwu Magma 1.2.0, emebere maka ntinye ngwa ngwa nke akụrụngwa iji kwado netwọkụ ekwentị 2G, 3G, 4G na 5G. Facebook malitere ikpo okwu dịka akụkụ nke atumatu iji hụ na ịnweta netwọkụ zuru ụwa ọnụ, mana gbanwee ya ka ọ bụrụ ọrụ dị iche nke ebufere n'okpuru nkwado nke ọgbakọ anaghị akwụ ụgwọ nọọrọ onwe ha OpenStack Foundation. Edere koodu ahụ na C, C++, Go na Python, na kesara site n'okpuru ikikere BSD.

Igwe ikpo okwu na-enye ụzọ ọhụrụ maka ọrụ nke ndị na-arụ ọrụ telecom, dabere na iji ngwanrọ mepere emepe na ikwe ka ịmepụta ụdị netwọk ọhụrụ nke na-eji usoro mmelite ngwa ngwa na ntinye nke ngwa ngwa ngwa ngwa. Ebumnuche bụ isi nke mmepe Magma bụ ịgbalị ịmepụta ikpo okwu maka iwulite netwọk mkpanaka ọgbara ọhụrụ nke ọma, dakọtara na mmejuputa ọdụ ọdụ LTE dị ugbu a yana njikwa etiti site na ihe ndị na-agba ọsọ na nzuzo ma ọ bụ gburugburu igwe ojii.

Ikpo okwu na-enyekwa ngwaọrụ akpaaka nke na-eme ka ibugharị akụrụngwa ọkpụkpụ dị mfe dị ka ịgba ọsọ ebe ịnweta Wi-Fi. Enwere ike iji Magma na njikọ netwọkụ ndị dị adị (LTE core network) iji gbasaa ọrụ ha n'ihe gbasara ịmalite ọrụ ọhụrụ na ịhazi njikọ nke netwọk dị iche iche. Site na Magma, ndị na-ahụ maka telecom nwere ikike dị iche iche nwere ikike ịgbasa ike netwọkụ ma ọ bụ bulie mkpuchi na mpaghara siri ike iru site na iji Wi-Fi na CBRS. Dịka ọmụmaatụ, Magma nwere ike mee ngwangwa ntinye nke netwọkụ ekwentị n'ime ime obodo, enwere ike iji ya mepụta netwọk LTE nkeonwe ma ọ bụ sistemụ ikuku ụlọ ọrụ.

Magma na-agụnye ngwa ọrụ iji megharịa ntinye netwọkụ, ngwanrọ njikwa na akụrụngwa netwọkụ bụ isi iji hazie nnyefe ngwugwu. Iji belata mgbagwoju anya nke ijikwa netwọkụ mkpanaka, Magma na-enye ngwaọrụ iji megharịa nhazi, mmelite ngwanrọ na mgbakwunye nke ngwaọrụ ọhụrụ. Ọdịdị mepere emepe nke ọrụ ahụ na-enye ndị na-ahụ maka telecom ohere ịmepụta ihe ngwọta na-ejikọtaghị na otu onye na-eweta ngwá ọrụ, na-enye mgbanwe dị ukwuu na amụma amụma, ma na-enyekwa ohere maka ịgbakwunye ọrụ na ngwa ọhụrụ.

Igodo Akụkụ Magma:

• AGW (Access Gateway) bụ ụzọ nnweta nke na-enye mmejuputa PGW (Packet Data Network Gateway), SGW (Serving Gateway), MME (Mobility Management Entity) na AAA (Nnwale, ikike na Akaụntụ). Usoro SGW na ụzọ ngwugwu gaa ọdụ ọdụ. PGW na-enye njikọ onye debanyere aha na netwọk dị n'èzí, na-eme nzacha ngwugwu na ịgba ụgwọ. MME na-enye agagharị, na-akwado mmegharị ndị debanyere aha ma na-eme njem n'etiti ọdụ ụgbọ ala. AAA na-enye ọrụ netwọk maka nyocha, ikike na ndekọ ndị debanyere aha. Na-akwado ịrụ ọrụ na akụrụngwa dị maka netwọkụ ekwentị.
• Federation Gateway bụ ọnụ ụzọ maka ijikọ na isi netwọk nke ndị na-arụ ọrụ mkpanaka, na-eji ọkọlọtọ 3GPP interface iji soro akụrụngwa netwọk dị ugbu a na-emekọrịta ihe. Ọ na-arụ ọrụ dị ka onye nnọchi anya n'etiti Access Gateway (AGW) na netwọk ndị na-ebu ya, na-enye ọrụ dị ka nyocha, chaja, ịgbakọ ego, na itinye mmachi atụmatụ tarifu.
• Orchestrator bụ ọrụ njikwa igwe ojii maka ịhazi na nyochaa netwọk ikuku, gụnyere nyochaa arụmọrụ netwọkụ na nsochi usoro okporo ụzọ. A na-enye interface weebụ maka njikwa. Onye na-ahazi ihe nwere ike ịgba ọsọ na gburugburu igwe ojii ọkọlọtọ. A na-eji protocol emekọrịta ihe na AGW na Federation Gateway gRPC, na-agba ọsọ n'elu HTTP/2.

Na mwepụta ọhụrụ:

• Emezigharịrị nke ọma wee gbasaa NMS (Network Management Station), interface webụ maka ijikwa netwọkụ na ibuga netwọkụ ọhụrụ. Ọtụtụ atụmatụ dị na NMS chọrọ Elasticsearch ugbu a.
  
• Na mmejuputa nke AGW (Access Gateway) uzo uzo uzo na onodu “Bridged Mode” gbasaa ọnụọgụ nke atụmatụ maka ikenye adreesị IP nye ndị ọrụ. Ekenye IP site na ọdọ mmiri, iji DHCP, yana ọrụ IP static dị. Nkwado nnwale agbakwunyere maka ịgba ọtụtụ APN-SGi.
• agbakwunyere nkwado maka profaịlụ njikwa ọrụ omenala (QoS) iji tọọ atumatu mmachi okporo ụzọ. Enwere ike ịhazi ntọala QoS maka APN ọ bụla na-enye ohere njikọ.
