Abstract
This paper presents a history of the IPFIX working group, from initial chartering through development and testing, re-chartering and further development, and looking ahead to future developments. As a standardised way of exporting information about traffic flows, IPFIX has attracted a growing number of implementors, who have continued to develop it in useful ways without changing its underlying architecture. This makes it a good example of how to develop a new technology. Further, it demonstrates widespread recognition of the importance of network measurement in the development, deployment and production stages of networks and the applications that depend on them.
