              <p><tt>Hi, John!</tt></p>
              <p><tt>It depends on the logic of your platform. If you
                  have multiple FreeSWITCH servers behind OpenSIPS, and
                  you want to have a "global" limit, then you must do it
                  on OpenSIPS side. It is also recommended to do it
                  there because for example if the threashold is
                  reached, you don't have to load FreeSWITCH with
                  traffic that's about to be denied. However, if you
                  have local (per FreeSWITCH) limits, then you can do it
                  on the FreeSWITCH side (with the earlier
                  observations).</tt></p>
              <p><tt>Regarding the algorithm, it depends on what you
                  want to limit. If you want to do CPS, then TAILDROP or
                  RED is more suitable. If you want to do a limitation
                  based on the network load, then use NETWORK.</tt></p>
              <p><tt>Also take into account that the way RED and
                  TAILDROP algorithm work, they are not so accurate.
                  That's why in OpenSIPS 2.2 we added a new algorithm,
                  SBT[1], which is very accurate and custamizable.</tt></p>
