A clock synchronization system and method in a communication network comprise a plurality of nodes in communication with each other by data transfer over communication links. Each of the nodes has its own local time base and exchanges timing information with a predefined node called master whose time base is the master clock against which said local time base is to be synchronized. At predefined moments in time, each node having a master exchanges timing information with the master node, calculates therefrom a timing data and stores said timing data into a predefined storage location called History; such as to obtain after at least two exchanges, a sequence of timing data stored in the History. From said sequence of timing data, a set of parameters is calculated and stored. The stored parameters are further used for computing a conversion function whereby the node local time is converted upon request into the master time base with a pre-specified and guaranteed precision.
In a communication network comprising a plurality of nodes in communication with each other by data transfer over communication links, with each of the nodes having its own local time base and exchanging timing information with a predefined master node having a master time base which serves as a master clock against which said local time base is to be synchronized, a clock synchronization method for converting the node local time into the master time base, comprising the steps of:
A communication network node comprising:
In a communication network, a clock synchronization system using a continuous conversion function for synchronizing local clocks of nodes in the network, comprising:
