Abstract
A technique for facilitating clock recovery in a node of a packet-based network is disclosed. The node is synchronized with other nodes based on a master-slave clock mechanism. A list of backup master clock node is maintained for the node, which includes at least one backup master clock node for the node, and in response to occurrence of a synchronization related event, a master clock node of the node is switched from the current master clock node to a backup master clock node selected from the list. A master clock node reselection message is generated and transmitted to the switched backup master clock node for the switched backup master clock node to reselect its master clock node.
