This paper introduces several collections of computer networking protocol animations that can be used in conjunction with classroom instruction. Some of these animations allow users to change parameters and settings, thereby enhancing the interactive learning. Additionally, this paper discusses in Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay , packet loss or the blocking of new connections.

Flow control tells the sender how much data to send. It makes the sender wait for some sort It makes the sender wait for some sort of an acknowledgment (ACK) before continuing to send more data. Abstract—This paper proposes a novel and efficient distributed flow control scheme for multirate multicast (MR-M), based on the well-known Proportional Integral and Derivative (PID) controllers. The PID controller at each router computes its expected incoming rate and feed backs this rate to its
