亞馬遜、蘋果與谷歌、三星開源智能家居設備商兼容性FA-20H愛普生晶振Q24FA20H0016600
Zigbee和藍牙都是不適配IPv6的底層協(xié)議,例如ZigBee,它規(guī)定了要求的底層協(xié)議、專用的網(wǎng)絡層/傳輸層和專用的應用層.所以Matter與Zigbee、藍牙是互斥的協(xié)議,無法共同存在;而與Wi-Fi則是依賴關系.由此可見,Matter是基于傳輸層之上的應用層協(xié)議,愛普生晶振它依賴于以太網(wǎng)、Wi-Fi、Thread等底層協(xié)議.應用層為Matter、傳輸層為TCP/UDP、網(wǎng)絡層為IPv6、底層為適配IPv6的協(xié)議以太網(wǎng)、Wi-Fi、Thread,等等.智能家居設備商兼容性Matter1.0的誕生2019年12月智能家居開源標準Matter首次由亞馬遜、蘋果、谷歌、三星SmartThings和ZigBee聯(lián)盟聯(lián)合發(fā)起提出.

當時還被稱為IP互聯(lián)家庭項目ProjectConnectedHomeoverIP,簡稱CHIP.該項目旨在開發(fā)、推廣一項免除專利費的新連接協(xié)議,將Zigbee、Thread、藍牙和Wi-Fi等不同組件整合到一個總體標準中,以簡化智能家居設備商開發(fā)成本,石英晶振提高產(chǎn)品之間兼容性.展示了Matter與ZigBee、藍牙、Wi-Fi的關系.OSI七層網(wǎng)絡模型大家都比較熟悉了,從高到低,依次為:應用層、表示層、會話層、傳輸層、網(wǎng)絡層、數(shù)據(jù)鏈路層、物理層.這里簡化了一下,將會話層和表示層合并到應用層,數(shù)據(jù)鏈路層和物理層合并到底層,形成新的網(wǎng)絡模型:應用層、傳輸層、網(wǎng)絡層、底層.
