To ensure the quality of service, especially for multiple applications, regulating the rate at which packets are sent to the network is an important strategy. The leaky bucket is just one of such mechanisms. A flow of packets is said to conform to the leaky bucket specification (r, b), where r is the average rate and b is the burst rate, if the number of packets arriving at the leaky bucket is less than r*t + b in every time interval of t. What is the implication of that? What will happen if the number of packets arriving at the leaky bucket is equal to or greater than r*t + b?
