Design Issues in Network Layer Network layer is majorly focused on getting packets from the source to the destination, routing error handling and congestion control. Before learning about design issues in the network layer, let’s learn about it’s various functions. Addressing: Maintains the address at the frame header of both source and destination and performs addressing to detect various devices in network. Packeting: This is performed by Internet Protocol. The network layer converts the packets from its upper layer. Routing: It is the most important functionality. The network layer chooses the most relevant and best path for the data transmission from source to destination. Inter-networking: It works to deliver a logical connection across multiple devices. Network layer design issues: The network layer comes with some design issues they are described as follows: 1. Store and Forward packet switching: The host sends the packet to the nearest route
