A method for facilitating tracking of packets through a plurality of localized transaction-tagging domains comprises determining a local tag applied within a first localized transaction-tagging domain to an output packet of the first localized transaction-tagging domain and assigning a system-generated global transaction tag to the output packet dependent upon the local tag. Assigning is performed in response to successfully performing the determining. The global transaction tag information is re-applied to an output packet of a second localized transaction-tagging domain after the packet is generated by the second localized transaction-tagging domain. The global transaction tag is a unique identifier that identifies all packets associated with a particular transaction globally across a plurality of localized transaction-tagging domains.
