It is estimation of this rate using exponentially weighted moving averaging (<a href="http://en.wikipedia.org/wiki/Moving_average" class="">http://en.wikipedia.org/wiki/Moving_average</a>), which is general technique for such estimation. You can try it and see if it would fit in your case.</div><div class=""><br class=""></div><div class="">—</div><div class="">Alex</div><br class=""><div><blockquote type="cite" class=""><div class="">On May 4, 2015, at 12:37 AM, Zhen Wu <<a href="mailto:wuzhen_mail@163.com" class="">wuzhen_mail@163.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="line-height: 1.7; font-size: 14px; font-family: Arial;" class=""><div style="line-height: 1.7; font-size: 14px; font-family: Arial;" class=""><div style="font-family: Helvetica, 'Microsoft Yahei', verdana;" class=""><span style="font-size: 18px;" class="">Dear,</span></div><span style="font-size: 18px;" class="">I want to get a face's received interest packet real-time rate. </span></div><div style="line-height: 1.7; font-size: 14px; font-family: Arial;" class=""><span style="font-size: 18px;" class="">I <span style="font-size: 18px; line-height: 1.7;" class="">have calulate it by counting the number of received interest in a second.But i find this method is not accurate.</span></span></div><div style="line-height: 1.7; font-size: 14px; font-family: Arial;" class=""><span style="font-size: 18px;" class=""><span style="font-size: 18px; line-height: 1.7;" class="">In simulation with --visual, we can see the real-time f</span><span class="" style="font-size: 18px; color: rgb(51, 51, 51); font-family: arial; line-height: 22px;">low rate，how does it get ?</span></span></div><div style="line-height: 1.7; font-size: 14px;" class=""><div style="font-family: Helvetica, 'Microsoft Yahei', verdana;" class=""><span style="font-size: 18px;" class="">thanks for all the researchers. i am wating for your reply...</span></div><div style="font-family: Helvetica, 'Microsoft Yahei', verdana;" class=""><span style="font-size: 18px;" class="">Wu</span></div></div></div></div></blockquote><br class=""></div></body></html>
