A controller (105) registers (205) a first number of channels; registers (210) a first number of clients (125); determines (215) a set of client groups a set of client groups and categorizing the registered clients into the client groups; and for each client group in the set, assigns (220) a corresponding subset of the registered channels; and communicates (225) the corresponding subset to each registered client therein. A RCD (125) registers (505) with the controller (105); and receives (510) a subset of the registered channels, the subset corresponding to a client group. In this manner, a RCD discovers a subset of channels in a network (130) to which it can subscribe that is appropriate for its resources and/or capabilities.
