Abstract
Embodiments provide a system and method for network tracking. By using packet capture applications having a flow identifier and a time stamper, one or more raw packets from one or more packet flows intercepted from a network can be tagged with a unique identifier and timestamp that can later be used to aggregate packet flows that have been analyzed by one or more capture applications. The unique identifier can relate to the network interface of the particular capture application and can also have an increasing value, where the increase in value can be monotonic. Later capture applications, while capable of generating secondary timestamps, can disregard those secondary timestamps for the primary timestamp of the first capture application in order to remove complications arising from latency issues.
