Abstract:
1. A method, comprising: partitioning a subset of nodes with each node including a router within a network of routers to create a clock partition, the clock partition comprising at least one clock source; sharing clock information from the at least one clock source with nodes within the clock partition and not sharing the information with nodes outside the clock partition; assigning a first clock partition identifier unique to the subset of nodes within the clock partition; appending the first clock partition identifier to a network clock distribution protocol (NCDP) message being sent from a first node to a second node; and disregarding the NCDP message sent from the first node if the first clock partition identifier of the first node does not match a second clock partition identifier of the second node with the second node being part of a different clock partition compared to the first node.
