or in conjunction with the company's M-5 Channel Adapter chip. THE Q-5 TMC As discussed previously, the sheer variety of applications that service providers must deliver while doing SO under a diversified set of requirements and customer-imposed end-to-end QoS levels spans the whole spectrum from voice over IP (VoIP) and streaming video all the way to web casting, with- out forgetting, of course, mundane data transfers. These diverse services are characterized by differ- ent traffic patterns and rates. As a result, building networking systems that implement these next-generation services requires active and sophisticated traffic management. Motorola has intro- duced the Q-5 TMC to address this need. The Q-5 performs its mission by being coupled without glue logic to the company's flagship network processor C-5e in order to provide QoS management into the data-forwarding path (data plane). 1.
