What is policing? |
Limiting traffic rates by dropping, re-marking, or transmitting traffic based on conformance |
|
|
Where can traffic policing be applied |
At the LAN or at the Network Edge |
|
|
What is traffic shaping? |
Regulating excessive traffic rates by delaying (buffering) traffic |
|
|
Where is traffic shaping applied? |
Usually at the network edge |
|
|
What is CIR, BC, and BE? |
CIR is the committed information rate, the rate of traffic for the queue BC is the committed burst that is allowed over the CIR BE is the excessive burst, providing another burst bucket above the BC |
|
|
What algorithm does the BC and BE use |
Token-bucket algorithm |
|
|
How much traffic is allowed per toket |
1 bit or 1 byte per token |
|
|
What are the three different types of class based policers? |
Single-rate two-color policer Single-rate three-color policer Two-rate three-color policer |
|
|
Which policer has a single token bucket and can action traffic that conforms or exceeds the rate? |
Single-rate two-color policer |
|
|
Which policer has two token buckets with tokens periodically added to the first bucket and any overflowing tokes going to the second bucket and can action based on conforms, exceeds and violates? |
Single-rate three-color policer |
|
|
Which policer has two token buckets with tokens periodically being added to both buckets at the same time and can action based on conforms, exceeds, and violates? |
Two-rate three-color policer |
