Abstract:
A method for synchronizing timestamps in a network that includes a control node and a plurality of other nodes that communicate with one another over a common channel mediated by a medium-access control subsystem, the method including the steps of:adding a first time interval value to a first value to provide a timestamp value; storing said timestamp value at said control node for a second time interval substantially equal to said first time interval, sending a timestamp command from the control node to said other nodes, at a first time, wherein said timestamp command comprises said timestamp value; storing said timestamp value in a register within each of the other nodes, in response to the timestamp command; wherein each of the other nodes computes a difference between the timestamp value and a current timestamp value, and then increments or decrements said current timestamp value by said computed difference.
