Important Reason for Use Flow Control in Network Layer
- Flow control mechanisms are not typically used in the network layer of the OSI model. The network layer primarily focuses on logical addressing, routing, and forwarding of packets across networks. Flow control is primarily implemented at lower layers such as the data link layer and transport layer. However, the network layer indirectly influences flow control through its routing functions.
- The network layer indirectly contributes to flow control by avoiding congestion and facilitating smooth data transfer.
- While flow control mechanisms are not typically employed at the network layer, the network layer plays a crucial role in managing network resources, congestion control, and load balancing. These functions indirectly influence the overall flow of data within the network by dynamically determining paths and ensuring efficient utilization of network resources.
- Congestion Management: Flow control at the network layer helps manage congestion within a network. It ensures that network resources are efficiently utilized and prevents network congestion caused by an overwhelming influx of data packets. By regulating the flow of packets, flow control helps maintain network performance and avoids packet loss or delays due to congestion.
- Fair Resource Allocation: Flow control mechanisms in the network layer promote fair allocation of network resources. By regulating the flow of packets, flow control prevents a single sender from monopolizing network resources, allowing all network nodes to have a fair chance of utilizing the available bandwidth.
Why Flow Control is Used in Both Data Link Layer and Network Layer?
OSI model was established in1947 by international standard organization is a multinational body dedicated to worldwide agreement on international standards.ISO standard covers all the aspects of network communications is the Open System Interconnection model.It was introduced in the late 1070s. an open system is a set of protocols that allows any two different systems to communicate regardless of their underlying architecture.The purpose of the OSI model is to show how to facilitate communication between different systems without requiring changes to the logic of the underlying hardware and software.
