Disadvantages of Network Layer
- There is no flow control mechanism provided by the network layer design.
- There may be times when there are too many datagrams in transit over the network, causing congestion. This could put further strain on the network routers. In some circumstances, the router may lose some data packets if there are too many datagrams. Important data may be lost in the process of transmission as a result of this.
- Indirect control cannot be implemented at the network layer since the data packets are broken up before being sent. Additionally, this layer lacks effective error control systems.
Network Layer in OSI Model
OSI stands for Open Systems Interconnection. It was developed by the ISO – ‘International Organization for Standardization‘, in the year 1984. It is a 7-layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another across the globe.
