Clock synchronization via a data packet network with the use of srts without conventional network timing

摘要

A process for recovering an application clock (service clock) by means of a data packet network for the provision of isochronous services, comprising– Providing the first and second constant of local oscillators at corresponding transmitter - and receiving node;– Use of a acr (adaptive clock receiver) - art, in order to provide a clock information between the transmitter - and receiving node via the data packet network without reference to a conventional network timing based on the difference between the frequency of the second constant frequency oscillator and the long-term average - frequency of arrival times to be transmitted between packets;– Use of the clock information, in order to the frequency of the second constant frequency to be adapted to local oscillator;– Generating time stamps, the use of clock pulse in relation to the first stable local oscillator setting;– The time stamp is transmitted to the receiving node;– Recovery of the application of clock pulse at the receiving node of the time stamps and the frequency adapted second stable local oscillator.
