Light-weight Flow Accounting Protocol Data Definition Specification Version 5.0

The Light-weight Flow Accounting Protocol Data Definition Specification defines the data which may be sent via the Light- weight Flow Accounting Protocol transport. LFAP transport and LFAP Data Definition, allow an external Flow Accounting Service (FAS) to record flow accounting information from a Connection Control Entity (CCE), allowing flexible Flow Accounting Services to be deployed by a vendor or customer without changes to, or undue burden on, the CCE. Specifically, this document specifies the data that may be exchanged between the CCE and the external FAS. Using LFAP, a FAS can maintain details of current or historical flows for billing, capacity planning and other purposes.
