The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.

As load exceeds network capacity, packets gets jammed at nodes. These packets never go forward unless load goes below network capacity. Hence when load exceeds network capacity delay tends to infinity. As load exceeds network capacity, packets gets jammed at nodes.
