Which of the Below is True About Shaping and Policing?
- Shaping can introduce a delay in packet propagation
- Policing marks and drops excess traffic if it crosses the threshold
- Policing can be done for inbound traffic
- Shaping buffers and queues the packets above CIR.
- All of the above
Explanation
All of the following statements are true about shaping and policing:
Shaping can introduce delay in packet propagation: Shaping is a technique that limits the rate at which packets are transmitted, in order to prevent overloading the network and ensure that all devices have access to the necessary bandwidth. When shaping is used, packets that exceed the configured rate are held in a buffer or queue, which can introduce a delay in packet propagation.
Policing marks and drops excess traffic if it crosses the threshold: Policing is a technique that is used to limit the rate at which packets are transmitted, in order to prevent overloading the network and ensure that all devices have access to the necessary bandwidth. If a packet exceeds the configured rate, it may be marked or dropped, depending on the configured behavior.
Policing can be done for inbound traffic: Policing can be applied to both inbound and outbound traffic. It is often used to ensure that incoming traffic conforms to the agreed-upon service level agreement (SLA) for a particular connection.
Shaping buffers and queues the packets above CIR: Shaping is a technique that is used to limit the rate at which packets are transmitted, in order to prevent overloading the network and ensure that all devices have access to the necessary bandwidth. If a packet exceeds the configured rate (known as the Committed Information Rate, or CIR), it is held in a buffer or queue until there is sufficient bandwidth available to transmit it.
Therefore, the correct answer is: All of the above
