Data is transferred from the source to the destination in a network. Sometimes the data is transferred in bulk in the network which affects the traffic. Now, if the traffic gets more and more in the network, therefore increasing the congestion. This leads to delay in data receiving or sending packet loss, and blocking of the connection resulting in the capacity of the network.
Network Congestion:- Network protocols are there which help in reducing the network traffic, by taking the SHORTEST PATH ALGORITHM which says that, the data is routed by seeing the shortest path of the desired destination.
