Abstract
An apparatus and method allow two or more members of a network, connected in multipoint-multipoint manner, to synchronize their local service clocks. Overall synchronization is achieved as soon as every member within the network transports its own timing information to other members of the group, plus the maximum propagation delay between the group members, and accordingly minimizes the possibility of overruns and underruns at each node end. Such synchronization is implemented when all members of a network synchronize their internal clocks to a lowest clock frequency within the network.
