Abstract:
1. A method to manage congestion in a network, the method comprising: determining a congestion status associated with a node in a single peer group or a hierarchical level in the network, the congestion status being represented by a transit flag accessible to at least one other node in the single peer group or the hierarchical level to determine if a call is routed through the node; and broadcasting the congestion status from the node to the at least one other node in the single peer group or the hierarchical level, wherein determining the congestion status comprises: setting the transit flag, if the congestion status indicates a congestion, to indicate that a call through the node is avoided unless the node is a terminating node; and resetting the transit flag, if the congestion status does not indicate a congestion, to indicate that the node is not restricted for transit.
