Question

Congestion management method, not a congestion avoidance method. Traffic flows are identified by _____ based on the source and destination IP address, port number, protocol number, and ToS.

a. RED
b. WFQ
c. FIFO
d. WRED

Answer 1

The congestion management method that identifies traffic flows based on the source and destination IP address, port number, protocol number, and ToS is WRED (Weighted Random Early Detection).

Step-by-step explanation:

The congestion management method that identifies traffic flows based on the source and destination IP address, port number, protocol number, and ToS is WRED (Weighted Random Early Detection). WRED is a method used in network routers to manage congestion by selectively dropping packets before the network becomes overloaded. It assigns different levels of drop probability to different traffic flows based on their characteristics.
