Your company is designing a service provider network management solution in which customers are billed for 95th percentile network utilization.
The service provider requires that an IETF standard be utilized to collect the data.
Which method should be used to collect the data?

IPFIX is only one which is an IETF Standard.
The most appropriate method to collect the data for 95th percentile network utilization billing is IPFIX (Internet Protocol Flow Information Export).
IPFIX is an IETF standard (RFC 7011) that allows the export of network flow information to an external collector. It enables the measurement, collection, and export of flow data that can be used for network monitoring, accounting, and billing.
NetFlow is a Cisco proprietary protocol that performs similar functions as IPFIX. However, since the service provider requires an IETF standard, NetFlow would not be the best option.
RMON (Remote Monitoring) is a protocol that provides network monitoring and traffic analysis capabilities. RMON can collect data on network traffic, but it does not support flow data export and is not designed for billing purposes.
IPFLOW is not a standard protocol, but rather a term that can refer to various types of flow-based traffic analysis solutions.
NBAR (Network-Based Application Recognition) is a Cisco proprietary protocol that can identify and classify network traffic based on application-level protocols. While NBAR can provide some flow data, it is not primarily designed for flow collection and export.
In summary, IPFIX is the most appropriate method to collect flow data for billing purposes in a service provider network management solution, as it is an IETF standard designed specifically for flow data export.
