1. Synchronization: Txoj kev tswj hwm tso cai rau cov lus qhia thiab tawm kom pom zoo ib yam nkaus. Synchronization hom: tso zis synchronization; kaw hom: tswv yim synchronization.
2. Muaj nuj nqi: Muaj cov ntaub ntawv sib kis ntawm cov neeg siv ncig ntawm DP master chaw nres tsheb thiab DP qhev chaw nres tsheb. Kev ua kom zoo thiab ua kom txav tau ntawm txhua tus qhev DP. Txheeb xyuas qhov teeb meem ntawm DP qhev. Kev ua haujlwm muaj nuj nqi kuaj mob tseem ceeb, cov ntaub ntawv kuaj mob peb-theem. Synchronization ntawm cov tswv yim lossis cov zis. Muab chaw nyob rau DP qhev nyob rau hauv lub tsheb npav. Kho lub DP master chaw nres tsheb (DPM1) los ntawm cov kab, thiab cov ntaub ntawv tawm tswv yim thiab tawm ntawm txhua qhov chaw nres tsheb hauv DP qhev yog 246 bytes feem ntau.
