Metering capabilities refer to the ability of a network to measure, monitor, and manage the flow of data traffic in a Software-Defined Networking (SDN) environment. This involves tracking the amount of data transmitted through various network paths, which aids in understanding bandwidth usage and implementing quality of service (QoS) policies effectively. As SDN evolves, metering capabilities have become essential for dynamic resource allocation, traffic engineering, and enhancing overall network performance.
