Abstract Abstract
Clock synchronization protocols are very widely used in IP-based Clock synchronization protocols are very widely used in IP-based
networks. The Network Time Protocol (NTP) has been commonly deployed networks. The Network Time Protocol (NTP) has been commonly deployed
for many years, and the last few years have seen an increasingly for many years, and the last few years have seen an increasingly
rapid deployment of the Precision Time Protocol (PTP). As time- rapid deployment of the Precision Time Protocol (PTP). As time-
sensitive applications evolve, clock accuracy requirements are sensitive applications evolve, clock accuracy requirements are
becoming increasingly stringent, requiring the time synchronization becoming increasingly stringent, requiring the time synchronization
protocols to provide high accuracy. Slave Diversity is a recently protocols to provide high accuracy. Slave Diversity is a recently
