23.4. Scenarios: Setting up Traffic Shaping
Example:
More than one pipe can be connected into a pipe chain to make bandwidth
limits more restrict. In the previous example–Applying precedence on pipe
limits, a 500kbps limit on precedence "Medium" is defined on pipe "std-in".
The "HTTP" rule says that HTTP response from the Internet can use up
to 500kbps as higher priority traffic, and the traffic exceeding this limit will
fall into priority "Low" specified by the standard rule "FromInternet".
Such traffic will compete the remaining 500kbps with all the other
traffics(The total limits defined for "std-in" is 1000kbps).
If we want to guarantee that other traffics always have at least 500kbps
without competing with the exceeded HTTP traffic, we can add an
additional pipe "http-in" that limits the total bandwidth consumption to
500kbps, and revise the pipe rule "HTTP" to have a pipe chain on the
return direction. In this chain, "http-in" is put in front on "std-in". Traffic
belongs to HTTP will need to pass the total limits in "http-in" first before
it can go into "std-in". Exceeded HTTP traffic will be queued on "http-in".
