Which of the following statements is true concerning TCP’s congestion control?Question 24AnswerIt is used by ISPs to control the traffic in the networkIt changes the sending rate dynamically according to indicators of the network’s traffic conditionsIt is a mechanism used by routers to reduce the network trafficIt allows the sender to slow down so that the receiver is not overwhelmed.

3.6-3 Different approaches towards congestion control. Use the pulldown menu to match a congestion control approach to how the sender detects congestion.Group of answer choicesThe sender infers segment loss from the absence of an ACK from the receiver.Bits are set at a congested router in a sender-to-receiver datagram, and bits are in the returned to the sender in a receiver-to sender ACK, to indicate congestion to the sender.The sender measures RTTs and uses the current RTT measurement to infer the level of congestion.

The term "congestion collapse" refers to:Question 1AnswerA reduction in throughput as demand for network capacity increasesBuffer fullness increasing without bounds in routersA network becoming so congested that connections start to drop outThe point at which packets start to get dropped as a result of buffer overflow in routers.
