Question

What are the difference between open loop and closed loop congestion control system?

Answer 1

Explanation:

One of the significant difference between the open loop and closed loop control system is that in an open loop system the desired output does not depend on the control action. While in the closed loop system the desired output depends on the control action of the system. 

Open-loop congestion control policies try to prevent congestion. Closed-loop congestion control policies try to alleviate the effects of congestion."
