Explain the functionality of a Gateway. - A set of data rates are advertised by any gateway server. Some streams can be blocked by a gateway server from reaching the SP, in case the SP is opted for this service. - The gateway is associated with a multicast (non-gateway) channel. The gateway needs to listen to the non-gateway channel, and any other SP that is currently serviced by it. - A pass-through service is offered by the gateway server in the case of non-crucial data rate control, and a tunnel is established by it and provides the forwarding service.
