Assume That There Are Four Flows A, B, C, and D

question 313

Multiple Choice

Assume that there are four flows a, b, c, and d, the transmission rate of each flow is 50 Mbit/s, and the total bandwidth of the interface for flow transmission is 100 Mbit/s. In the case of congestion, WFQ is available for flows a, b, c, and d, with the weight proportion being 1:2:3:4. Which of the following statement about the interface bandwidth allocated to each flow is true?

• A) Interface bandwidths allocated to flows a, b, c, and d are 10 Mbit/s, 20 Mbit/s, 30 Mbit/s, and 40 Mbit/s respectively.
• B) Interface bandwidths allocated to flows a, b, c, and d are 50 Mbit/s, 50 Mbit/s, 0 Mbit/s, and 0 Mbit/s respectively.
• C) Interface bandwidths allocated to flows a, b, c, and d are 40 Mbit/s, 30 Mbit/s, 20 Mbit/s, and 10 Mbit/s respectively.
• D) Flows a, b, c, and d are discarded.
