Hey Nhan, I think your understanding is basically right in that policing will drop excess traffic normally and shaping will average the rate out to the speed you specify over time. As far as which one to use when, I would look for specific key words in the task and make sure you read it very carefully.
For instance if it states that http should get NO MORE THAN 512k that is likely policing. If it specifically asks you to shape, anything about peak shaping, average shaping, etc you want to shape.

So only benefit to use policing over shaping is when we are dealing with RTP/Voice/Video/UDP traffics, because if these traffics arrive late, they are useless. All other case shaping is better because at least these traffics will queue up Thanks, Nhan Yahoo! Canada Toolbar : Search from anywhere on the web and bookmark your favourite sites.
