1.	The technique in which a congested node stops receiving data from the immediate upstream node or nodes is called as _______(a) Admission policy(b) Backpressure(c) Forward signaling(d) Backward signalingI had been asked this question in quiz.My enquiry is from Congestion Control in division Frame Relay of Computer Network
Answer» The correct option is (b) Backpressure To EXPLAIN I would say: In this closed loop congestion control TECHNIQUE, the congested node propagates in the opposite direction of the data flow to inform the predecessor node to reduce the flow of PACKETS. This is why this technique is CALLED a node-to-node congestion control technique.
