What shape does one sender rate trace over time?

• A flat line
• Climb, sharp drop, climb again
• A single jump to max

What does a sender treat a lost packet as?

• News that the path is full
• Proof the cable was cut
• A request for larger packets

While packets land, the sender raises its rate.

Circle one:   True   False

One sender never slows while the rest back off. What follows?

• The cheat grabs the queue and all suffer
• The polite ones speed up instead
• The link grows new capacity

Losses start arriving. What should the sender do?

• Double the rate at once
• Hold the rate exactly still
• Cut sharply, then climb gently

Why is loss called a signal rather than only a fault?

• It sounds an alarm bell
• It deletes the whole file
• It carries news about path load

A lone cheat on a shared link harms only itself.

Circle one:   True   False

All senders double their rates after each loss instead of cutting. What happens?

• The link empties nicely
• Queues bloat and throughput collapses
• Losses turn into extra capacity
