Kwihlabathi le-IoT, i-architecture yenethiwekhi eqhelekileyo ilandelayo. Okokuqala, isixhobo se-terminal okanye inzwa iqokelela imiqondiso okanye ulwazi. Kwizixhobo ezingakwazi ukufikelela kwi-Intanethi okanye kwinethiwekhi ye-intranet, inzwa kuqala ithumela ulwazi olufunyenweyo kwisango le-IoT, kwaye emva koko isango lithumela ulwazi kumncedisi; ezinye izixhobo zinemisebenzi yazo yokufikelela kuthungelwano, njengeefowuni eziphathwayo, ezinokudityaniswa ngokuthe ngqo kumncedisi.
Ngamanye amaxesha, ukuze sinciphise umncedisi, sinokukhetha ezinye iiprothokholi zonxibelelwano olulula, njenge-MQTT endaweni ye-HTTP, ngoko kutheni ukhetha i-MQTT endaweni ye-HTTP? Ngenxa yokuba i-header yeprotocol ye-HTTP inkulu, kwaye rhoqo xa idatha ithunyelwa, ipakethi ithunyelwa ukuxhuma / ukukhupha i-TCP, ngoko ke idatha eninzi ithunyelwa, inkulu i-traffic data iyonke.
Intloko ye-MQTT incinci, kwaye inokuthumela kwaye ifumane idatha elandelayo ngelixa igcina uxhulumaniso lwe-TCP, ngoko inokucinezela i-traffic data iyonke ngaphezu kwe-HTTP.
Ukongezelela, xa usebenzisa i-MQTT, umntu kufuneka kwakhona anikele ingqalelo kuloo nto, ngelixa egcina uxhulumaniso lwe-TCP ye-MQTT, idatha kufuneka ithunyelwe kwaye ifunyenwe. Ngenxa yokuba i-MQTT inciphisa unxibelelwano ngokugcina uxhulumaniso lwe-TCP, ukuba unqamula uxhulumaniso lwe-TCP rhoqo xa unxibelelwano lwedatha lwenziwa, i-MQTT iya kwenza uxhulumaniso kunye nokuqhawulwa koqhagamshelwano rhoqo xa idatha ithunyelwa, njenge-HTTP, kodwa umphumo uya kwandisa unxibelelwano. umthamo.
Ngaba uyafuna ukufunda ngakumbi malunga nendlela isango le-IoT elisebenza ngayo? Zive ukhululekile ukuqhagamshelana neFeasycom Ltd.
