COMPUTER NETWORKING

Detailed explanation-1: -Explanation: In the congestion avoidance algorithm, the size of the congestion window increases additively until congestion is detected. Once congestion is detected, the size of congestion window is decreased once and then the packets are transmitted to achieve congestion avoidance.

Detailed explanation-2: -Congestion control in network layer occurs when a node or link carries data beyond its limit. This often leads to the queuing of packets-and in the worst case, loss of packets-as well as a decrease in the network’s Quality of Service (QoS).

Detailed explanation-3: -If the congestion window is too large, the rate at which packets are sent will exceed the network capacity, resulting in packet losses and/or delays. If the congestion window is too small, traffic might be sent too slowly for good quality of experience.
