Fairness and congestion control in LAN/WAN protocol relays

This paper addresses the problem of congestion control and fairness in relay systems for Connection Mode LAN/WAN interworking. To ensure congestion collapse avoidance and fairness against QoS (Quality of Service) parameters, a channel service algorithm and a flow control algorithm are proposed and evaluated by simulations. Results show that, in a situation of overload and for different traffic patterns with different QoS requirements, the relay´s channel service and flow control algorithms can guarantee justice in relay resource utilization and the expected QoS among the active channels
