Question

Congestion avoidance mechanism that addresses packet loss caused by tail drop. This occurs when new incoming packets are dropped due to the router's stacked queue. Useful for networks where the majority of traffic uses TCP because TCP packets that are dropped must be retransmitted. Additionally, TCP sources reduce traffic flow when congestion occurs, further slowing down the network. This is called ________ (Acronym)

a) RED (Random Early Detection).
b) TCP (Transmission Control Protocol).
c) QoS (Quality of Service).
d) ICMP (Internet Control Message Protocol).

Answer 1

The correct answer is RED (Random Early Detection). RED is a congestion avoidance mechanism that addresses tail drop by dropping packets early when the network is congested. It is particularly useful for networks that use TCP.

Step-by-step explanation:

The correct answer to the question is a) RED (Random Early Detection).

RED is a congestion avoidance mechanism used in computer networks. It is designed to prevent packet loss caused by tail drop by dropping packets early when the network is congested. By dropping packets early, it allows the sending devices to reduce their transmission rates and prevent further congestion.

RED is particularly useful for networks that primarily use TCP (Transmission Control Protocol). TCP relies on dropped packets as an indicator of network congestion, and when packets are dropped, TCP sources will reduce their transmission rates. By using RED, TCP sources can react and reduce their transmission rates before congestion occurs, minimizing packet loss and improving overall network performance.
