Congestion control does ensure that the network does not become saturated at any one point. This ensures that there is no compromise in the quality of service.

What are the congestion prevention policies in network layer?

What is the use of a control network?
A control network is used to control other networks. The networks have their own structure but are controlled remotely by another network connected by a gateway.
What is elastic and inelastic internet traffic?
Elastic traffic: -adjust its throughput between end hosts in response to network condition. - Generally TCP-based application (HTTP,STMP,FTP) - Principle form of feedback: packet loss caused by network load/congestion, causing TCP to implements its congestion avoidance algorithm and reduce the rate at which packets are sent over the network -TCP traffic is considered to be "network friendly" Inelastic traffic: - does not adjust its throughput in response to network conditions - generally real-time multimedia (audio streaming, video,VoIP)
What would one do with control access?
Access control allows an admin to control the system or network from one central location. This level of control make administering a network much easier.
Advantages and disadvantages of Network Tapologies?
centralized control
What ensures that the network does not become saturated at any one point?
Flow control ensures that the network does not become saturated at any one point. By directing traffic in the best direction, network hardware is capable of balancing the load efficiently and accurately.
How can you control the congestion in tcp?
The techniques include End-system flow control, Network congestion control, Network based congestion avoidance and Resource allocation.
Which layer is done by congestion control?
at the network layer, congestion control mechanism takes place
How does TCP detect congestion?
It don't control congestion that is up to the routers and gateways as they are the ones that look at the traffic and figure out the best way to send something over the internet.
Are the objectives of flow control and congestion control the same?
Average rate will remain same but Flow control: end-to-end mechanism for regulating traffic between source and destination • Congestion control: Mechanism used by the network to limit congestion
How does congestion control and QOS related?
In congestion control, the load on a network is prevented from exceeding the capacity. Quality of service refers to the characteristics that a flow of data seeks to attain. If there is good congestion control, then the QoS is also good and vice versa.
What are the congestion prevention policies in network layer?

In which OSI layer does congestion occurs?
congestion is Traffic in excess of network capacity. it occurs network layer and it is one of the function of network layer.
Which layer of the OSI can route packets to eliminate problems like network congestion?
If you are talking strictly about routing, then layer 3 (the Network layer). There are some routing protocols, usually known as link-state routing protocols that are aware of network congestion problems and can re-route as necessary. Network congestion is not restricted to routing alone, however. At layer 4 (Transport Layer) there is a facility known as flow control, which can pause a sending network if the receiving network is too busy to accommodate all the packets.
How does TCP try to avoid network meltdown?
No, TCP is responsible for reliable transport delivery. It doesn't know about network congestion (other than flow control caused by ICMP messages).
What is the difference between flow control and congestion control?
Flow control vs. congestion control: Flow control means preventing the source from sending data that the sink will end up dropping because it runs out of buffer space. This is fairly easy with a sliding window protocol--just make sure the source's window is no larger than the free space in the sink's buffer. TCP does this by letting the sink advertise its free buffer space in the window field of the acks. Congestion control means preventing (or trying to prevent) the source from sending data that will end up getting dropped by a router because its queue is full. This is more complicated, because packets from different sources travelling different paths can converge on the same queue.
What is another term for network congestion?
