Abstract
A system and method are provided for tracking a data transfer transaction across a multi-hop network. The system includes a number of devices that conduct a data transfer transaction across the multi-hop network. The data transfer transaction may occur in one or more transfer segments. The devices generally include an origination device and a destination device. The system also includes a service device in communication with the several devices. The service device generates a globally unique transaction identifier that is associated with each data transfer transaction undertaken via the multi-hop network. Since there is no field included in the data that is transferred that facilitates tracking of the data transfer transaction, a tracking table is maintained in the service device to track the data transfer transaction from the origination device to the destination device. The tracking table is associated with the globally unique transaction identifier and includes information from the various devices involved in the data transfer transaction across the multi-hop network.
