There are several approaches to prioritizing multiple applications on a converged network. Zeugma does it with a product that analysts are beginning to call Service Delivery Router. One of the major issues – going back to the RSVP days – in convergence is how to offer a multi-tiered service. For example, it would be plausible to assume that somewhere down the line a service provider would offer a two-tiered voice service … one that is a high-quality high-price HD voice service, and the other that involves an inexpensive best efforts voice service. Zeugma product does exactly that sort of thing for multiple application types.
