ABSTRACT:
A bandwidth control method and a bandwidth control device for a network switch are disclosed. When a client port has a packet to be transmitted, the average traffic rate Tr[n+1] of the client port generated before the time slot n+1 is determined by Tr[n+1]=g*TrΔ[n]+(1−g)*Tr[n], where g<1, TrΔ[n] is the traffic rate of the client port in time slot n, and Tr[n] is an actual average traffic rate generated before time slot n. Only when Tr[n+1] is smaller than the bandwidth threshold Tr_pre of the client port, the packet is allowed to be transmitted.
