Abstract
The invention relates to a method or an arrangement for the clock synchronization of a plurality of distributed modules of an information or communication system, said modules being coupled via a packet-switched network. At least two of said modules are controlled by a local clock generator of the modules using an adjustable frequency, and a clock signal is transmitted via the network in the form of clock signal packets in a synchronous minter with respect to the local clock of the modules. One of said at least two modules takes over the function of a master module, and all remaining said at least two modules, the slave module(s), synchronize the local clock of the modules with the clock of the master module, wherein said slave modules ascertain a measurement for the deviation of the local clock generator of the modules relative to the clock generator of the master module by comparing the clock signal transmitted by the master module with the clock signal of the modules and use said measurement in order to regulate the local clock generator of the modules.
