Claim:
1. A method of configuring a node of a synchronization network, the method comprising the steps of: a) determining information about synchronization sources of a plurality of active synchronization trails passing synchronization information from the synchronization sources to the node to provide a synchronization reference, a part of at least one of the plurality of active synchronization trails using packet-based communication to pass the synchronization information; b) determining automatically synchronization transmission characteristics of the part of at least one of the plurality of active synchronization trails using packet-based communication, the synchronization transmission characteristics comprising at least one of jitter and delays; c) comparing automatically the trails leading to the node, using the determined synchronization source information and using the determined synchronization transmission characteristics; d) based on the comparing of the trails leading to the node, selecting which of the plurality of active synchronization trails to use for providing the synchronization reference for the node; e) receiving at the node an update of the synchronization transmission characteristics; f) reassessing the selection based on the updated synchronization transmission characteristics; and g) selecting a new one of the synchronization trails for passing the synchronization information for use as the synchronization reference.
