Detailed explanation-1: -1. Choke Packet : Choke packet technique can be implemented in to both virtual networks and datagram subnets. A special packet called choke packet is released to source by congested node with information about congestion . Every router checks its output line and resource utilization .

Detailed explanation-2: -In the slow-start phase the window size starts from 1 and grows exponentially until it reaches the threshold. After it reaches the threshold, the congestion avoidance (additive increase) procedure allows the window size to increase linearly until a timeout occurs or the maximum window size is reached.
