Abstract
A method and apparatus for determining information associated with a particular multicast channel in a multicast network are disclosed. In accordance with the method, a request message requesting information associated with the particular multicast channel is generated and sent to the multicast network. Further, the request message is propagated downstream in a recursive manner via a multicast topology of the multicast network. A response to the request message is propagated upstream via the multicast topology to generate a response message including requested information associated with the particular multicast channel. The information may comprise number of users receiving the particular multicast channel.
