Emhlabeni we-IoT, ukwakhiwa kwenethiwekhi okujwayelekile kungokulandelayo. Okokuqala, idivayisi yetheminali noma inzwa iqoqa amasignali noma ulwazi. Ngamadivaysi angakwazi ukufinyelela i-inthanethi noma inethiwekhi ye-intranet, inzwa kuqala ithumela ulwazi olutholiwe ku-IoT gateway, bese isango lithumela ulwazi kuseva; amanye amadivaysi anemisebenzi yawo yokufinyelela inethiwekhi, njengamaselula, angaxhunywa ngqo kuseva.
Kwesinye isikhathi, ukuze sinciphise iseva, singakhetha izinqubo zokuxhumana ezingasindi, njenge-MQTT esikhundleni se-HTTP, kungani-ke ukhetha i-MQTT esikhundleni se-HTTP? Ngenxa yokuthi unhlokweni wephrothokholi ye-HTTP bukhulu ngokuqhathaniswa, futhi njalo uma idatha ithunyelwa, iphakethe lithunyelwa ukuze kuxhunywe/kunqamulwe i-TCP, ngakho uma idatha eyengeziwe ithunyelwa, kuba mkhulu inani ledatha yedatha.
Unhlokweni we-MQTT mncane kakhulu, futhi ungathumela futhi wamukele idatha elandelayo ngenkathi igcina uxhumo lwe-TCP, ukuze icindezele inani ledatha yedatha ngaphezu kwe-HTTP.
Ukwengeza, lapho usebenzisa i-MQTT, umuntu kufanele futhi anake lokho, ngenkathi egcina uxhumano lwe-TCP lwe-MQTT, idatha kufanele ithunyelwe futhi yamukelwe. Ngenxa yokuthi i-MQTT inciphisa inani lokuxhumana ngokugcina uxhumano lwe-TCP, uma unqamula uxhumano lwe-TCP njalo lapho ukuxhumana kwedatha kwenziwa, i-MQTT izokwenza uxhumano nokucubungula ukunqanyulwa njalo lapho idatha ithunyelwa, njenge-HTTP, kodwa umphumela uzokwandisa ukuxhumana. umthamo.
Ingabe ufuna ukufunda okwengeziwe mayelana nokuthi isango le-IoT lisebenza kanjani? Zizwe ukhululekile ukuxhumana ne-Feasycom Ltd.
