Question

Congestion management method, not a congestion avoidance method. Basic queuing method that offers no packet prioritization or congestion avoidance.

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

Answer 1

FIFO (First-In-First-Out) is a basic queuing method for congestion management, offering no packet prioritization or congestion avoidance. It processes packets in the order they arrive, lacking sophisticated mechanisms like RED (Random Early Detection) or WRED (Weighted Random Early Detection). So option C is correct

Step-by-step explanation:

FIFO (First-In-First-Out) is a straightforward congestion management method where packets are processed in the order they arrive, making it the correct choice (c). Unlike advanced methods like RED or WRED, FIFO lacks packet prioritization or congestion avoidance mechanisms.

It operates on the principle of processing packets based on their arrival time, regardless of their urgency or importance. While it is a simple and easy-to-implement queuing method, FIFO may lead to performance issues in congested networks, as it doesn't consider factors such as packet priority or the severity of network congestion.

More sophisticated methods like RED introduce early detection and potential discarding of packets to better manage congestion, which FIFO, being a basic queuing method, does not incorporate. S o correct option is C.

Answer 2

It is a basic queuing method that follows the First-In-First-Out principle, offering no packet prioritization or congestion avoidance features. It transmits packets in the order they arrive, without considering their priority or network conditions. Thus, the correct answer is option c) FIFO

Step-by-step explanation:

First-In-First-Out (FIFO) is a basic queuing method that offers no packet prioritization or congestion avoidance. In FIFO, the order in which packets arrive is the order in which they are transmitted, without considering the priority or congestion levels. Unlike other options listed, FIFO does not implement any sophisticated algorithms to manage congestion or prioritize packets based on their importance or network conditions.

FIFO works on the principle of fairness, where each packet is treated equally in terms of transmission priority, regardless of its content or the state of the network. While this simplicity makes it easy to implement and understand, it may lead to suboptimal performance in situations where congestion occurs, as it lacks mechanisms to adapt to varying network conditions.

Thus, the correct answer is option c) FIFO
