shape vs. policy

[rmv72]

Which is the better solution to use on interface?

[devang_etcom · Accepted solution]

first of all understand the difference between both:

shaping:

it retains excess packet in queue and then schedules the excess for later transmission over time... the result of traffic shaping is a smoothen=d packet output rate...

policing:

it propagates bursts...when traffice rate reaches the configured max rate, excess traffice is dropped. the result in an output is an output rate appear as saw tooth nature...

so noramlly at client end we have SHAPING and at ISP side we have POLICING...

hope this helps you

Hi,

What do you mean by "better"? It's not uncommon to use them in tandem.

See the following link for a comparison:
