Problems with the Network layer design
- The decision of how to direct packets is a pivotal aspect of network layer design. It holds great significance as it sets the groundwork for the protocol governing the transmission of packets between nodes in a network.
- In the nodes, data transmission can be facilitated through either static tables or dynamic tables. These tables serve as the routes for the transmission of information. The paths may be pre-established or subject to frequent alteration.
- The smooth flow of data in the network can be disrupted unexpectedly if there is an overwhelming abundance of packets being transmitted or present on the network. Consequently, the network might encounter bottlenecks causing a decline in its performance.
- Separate protocols are needed to enable communication between the two networks.
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.
