ROSES AND THORNS

                  Congestion in the network is mainly due to traffic overload. The traffic overload is created when the sender and receiver misunderstands each other. When there is no proper synchronization between the sender and receiver, the traffic overload problem occurs. When the sender sends the data at a faster rate and the receiver receives it in a slower rate then there arises traffic. The reverse case is also possible. To avoid these traffic and subsequently the congestion there are many methods available like Leaky bucket concept. Congestion dramatically decreases the Quality of Service. Quality of Service (QoS) is the main thing that should be maintained in the networking concept. Hence a network should be free from congestion to maintain its QoS
