What is Decbit algorithm for congestion avoidance?
In congestion avoidance, each router monitor the load it is explicitly notify the end node ,when the congestion is about to occur.This notification is implementing by setting a binary congestion bit in the packets that flow through the router, known as DECbit .The destination host then copies this congestion bit into the ACK it sends back to the source. Finally, source adjust its sending rate so as to avoid the congestion.
What are some inventions for flight engineers?
Some inventions for flight engineers are the supercritical wing, and the rotary control mechanism.
What are the elements of a control system?
stimulus, receptor, afferent pathway, control center, efferent pathway, effector, response
Why do we connect a transistor to a DC motor?
Transistors are not normally connected to dc motors, but it is possible to use transistors in a speed-control mechanism for a motor.
How can design stick-slip machine?
Stick-slip machines are designed to provide more controllable motion than a traditional electric motor. The basic design consists of a motor a control board and a stick-slip mechanism. The motor is used to provide the power to move the stick-slip mechanism while the control board is used to regulate the speed and position of the mechanism. The stick-slip mechanism consists of an elastic element such as a spring or rubber band that is connected to a shaft. When the shaft rotates the elastic element is compressed and then released creating a stick-slip effect. To design a stick-slip machine the following steps must be taken: Choose an appropriate motor and control board. Design the stick-slip mechanism and select an appropriate elastic element. Select the appropriate shaft and bearing system. Integrate the motor control board stick-slip mechanism and shaft into a single system. Test the system and adjust as necessary for optimal performance.By following these steps it is possible to design and build a reliable controllable stick-slip machine.
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
Which layer is done by congestion control?
at the network layer, congestion control mechanism takes place
What mechanism is used by tcp to provide flow control?
the station window size the congestion window memory buffers receipt acknowledgement
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.
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.
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 manages data delivery if there is congestion on the host?
Flow Control
What are the 3 major components of the TCP congestion-control algorithm and give a brief explanation of each?
The three major components of the TCP congestion-control algorithm are slow start, congestion avoidance, and fast recovery. Slow Start: This phase begins with a small congestion window (cwnd) size, typically starting at one segment, and increases exponentially with each acknowledgment received, allowing the sender to probe the network capacity. Congestion Avoidance: Once the congestion window reaches a certain threshold (ssthresh), TCP transitions to this phase, where it increases the window size linearly to avoid overwhelming the network, thereby reducing the likelihood of congestion. Fast Recovery: This mechanism kicks in after packet loss is detected (usually through duplicate acknowledgments), allowing TCP to quickly reduce the congestion window and retransmit lost packets without returning to the slow start phase, thus improving overall efficiency.
Does congestion control ensures that the network does not become saturated at any one point?
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 is TCP-friendly?
TCP-Friendly Rate Control (TFRC) is a congestion control mechanism designed for unicast flows operating in an Internet environment and competing with TCP traffic. The goal is to compete fairly with TCP traffic on medium timescales, but to be much less variable than TCP on short timescales.[wiki]

Which Frame Relay flow control mechanism is used to signal routers that they should reduce the flow rate frames?
If there is a congestion in one direction, the FECN (forward explicit congestion notification) bit is set to inform routers in the forward direction (from the point of view of the traffic) about the congestion. Also, eventually some frames will travel back to the origin; in that case, the BECN (backword explicit congestion notification) bit is also set to inform the origin about the congestion.
