Mechanism for tracking traffic statistics on a per packet basis to enable variable price billing

摘要

A method, system and computer program product for generating variable price billing whereby a customer may balance its data traffic in response to such billing. A subsystem in an edge gateway may extract the packet header from a copy of a received packet of data associated with a session between a customer and a server and generate a key based on the extracted packet header. The key may be used to index into a table that may store pointers to particular statistics records associated with particular sessions. Once the subsystem identifies the statistics record associated with the current session, the subsystem may execute a per packet statistics update for the statistics record associated with the session. A per packet statistics update may include one or more of the following: time stamping arrival of the packet, updating packet count, updating byte count, determining transfer rate, determining distance packet traveled.
