Abstract: Systems and methods track state-based transactions. Event tokens from devices of one or more networks are collected, formatted, normalized and stored in association with state-based transactions. Each of the transaction instances, and the associated event tokens, is processed using transaction definitions and zero, one or more actions are performed in association with the transaction instance. Missing event may be determined for each incomplete transaction based upon the transaction definitions. Problems across multiple networks may be diagnosed by determining quality of service for each of the transactions. Transactions between peering networks may be settled by monetizing the state-based transactions and generating billing information based upon the monetized state-based transactions. Abnormal behavior within an enterprise network is identified by evaluating the event tokens to identify state-based transactions of abnormal behavior.
