2.3.7- Ef-prio |
|
 |
|
| Next example is implemented by DS on Linux
Distribution with the name Ef-prio. This is a very simple implementation of the Expedited Forwarding (EF)
class using a priority queuing discipline. Implementing this example in
Linux is very easy. Let's see how it works on Cisco. |
| The idea is having two classes: EF and BE.
EF packets will be assigned to a priority queue with a
bandwidth availability of 1500 Kbps; rest of packets are
considered BE traffic and will be assigned to a RED queing
discipline using min-threshold of 15 Kb,
max-threshold of 45 Kb and a drop probability of
0.4 (1/2.5); because Cisco requires integer
values we will use just 3 as the
mark-probability-denominator. |
| |
| Using Cisco CLI the implementation is very
easy too; just type in your router: |

|
Because BE class will include any traffic not marked as DSCP EF
(46), then we have to use the random-detect precedence command to
implement RED for all packets using the same configuration. |

Well, dear lectors, next example is efhtb. |
