How can you manage a congestion from a transport layer?

The well-known and widely used close-loop control mechanism is TCP congestion control, which is implemented at transport layer. control adjusts the transmission rate dynamically by controlling the window size, which specifies the number of unacknowledged packets allowed by the source process.

What is congestion describe different ways to handle congestion in the network?

Networks use congestion control and congestion avoidance techniques to try to avoid collapse. These include: exponential backoff in protocols such as CSMA/CA in 802.11 and the similar CSMA/CD in the original Ethernet, window reduction in TCP, and fair queueing in devices such as routers and network switches.

How you will control the congestion in this TCP network?

Case 1 : Retransmission due to Timeout – In this case congestion possibility is high. (a) ssthresh is reduced to half of the current window size. (c) start with slow start phase again. Case 2 : Retransmission due to 3 Acknowledgement Duplicates – In this case congestion possibility is less.

What is congestion control in network layer?

Congestion Control is a mechanism that controls the entry of data packets into the network, enabling a better use of a shared network infrastructure and avoiding congestive collapse. Congestive-Avoidance Algorithms (CAA) are implemented at the TCP layer as the mechanism to avoid congestive collapse in a network.

How many types of congestion control techniques are there explain?

In general, we can divide congestion control mechanisms into two broad categories: open-loop congestion control (prevention) and closed-loop congestion control (removal) as shown in the Following figure. In open-loop congestion control, policies are applied to prevent congestion before it happens.

What are the two types of congestion control?

 In Open Loop Congestion Control, policies are used to prevent the congestion before it happens.  Congestion control is handled either by the source or by the destination. II) Closed Loop Congestion Control:  Closed loop congestion control mechanisms try to remove the congestion after it happens.

What are the principles of congestion control?

This approach has three parts when applied to congestion control:

• Monitor the system to detect when and where congestion occurs.
• Pass this information to places where action can be taken.
• Adjust system operation to correct the problem.
