ABSTRACT:
The invention provides a system which monitors and controls upstream path congestion by utilizing a MAC layer protocol wherein an upstream communication cell is transmitted from a settop box to the headend. The upstream cell contains a message field and a retry count. The retry count is incremented upon failure of each attempt to communicate with the headend within the upstream path. A downstream cell from the headend to the settop terminals contains an acknowledgment field and an optional power control field. Upstream path congestion is monitored by the headend through averaging or other suitable monitoring all of the retry count field data which arrives from the network of settop terminals.
