Assume that the bandwidths of flows a, b, c, and d are all 100 Mbit/s. The total interface bandwidth is 200 Mbit/s. When network congestion occurs, congestion management is required.
If flows a, b, c, and d belong to WFQ queues and the weight ratio is 1:2:3:4, what are traffic volumes of the four flows?
A . The bandwidths of flows a, b, c, and d are 20 Mbit/s, 40 Mbit/s, 60 Mbit/s, and 80 Mbit/s.
B . The bandwidths of flows a, b, c, and d are 100 Mbit/s, 100 Mbit/s, 0 Mbit/s, and 0 Mbit/s.
C . The bandwidths of flows a, b, c, and d are 80 Mbit/s, 60 Mbit/s, 40 Mbit/s, and 20 Mbit/s.
D . All traffic is discarded due to congestion.
