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.
