View solution

Q. In _______ congestion control, mechanisms are used to alleviate congestion after it happens.

View solution

Q. The technique of ________refers to a congestion control mechanism in which a congested node stops receiving data from the immediate upstream node or nodes.

View solution

Q. A ___________ is a packet sent by a node to the source to inform it of congestion.

View solution

Q. In __________, there is no communication between the congested node or nodes and the source. The source guesses that there is a congestion somewhere in the network from other symptoms.
