In applications with a relatively lower average number of services flows per subscriber device (where a subscriber device is an STB, an eMTA, or a cable modem), we support a relatively higher-scale of subscriber devices. Conversely, in applications with a relatively higher average number of services flows per subscriber device, we support a relatively lower scale of subscriber devices.
