Abstract: A system and method for time synchronization on a network is provided. According to the system and method for time synchronization, a slave clock device does not continuously receive a time synchronization message periodically transferred from a master clock device and thus does not correct its time upon all such occasions. Rather, the slave clock device requests time information from the master clock device only when the slave clock device needs to correct its time, and receives a time synchronization message transferred from the master clock device and compensates for its time deviation only while the slave clock device is activated, thereby reducing its power consumption and amount of computation.

The method for dynamically managing hierarchical flows includes: receiving data packets, classifying the data packets according to attributes of the received data packets, and producing first flows; determining whether traffic of each of the first flows exceeds a predetermined bandwidth limit, and performing a packet drop process or producing second flows for first flows that exceed the bandwidth limit, according to a flow-specific policy; and performing second flow processing on the second flows according to a second flow policy. Only flows exceeding the bandwidth limit or causing congestion are hierarchically divided for management. This makes it possible to finely manage the flows without complex operations.
