Let’s suppose using rate-limit for managing QoS. The quota parameters could be such as rate_limit (per port) and max_bandwidth (per tenant). In this way it is possible to set/manage QoS quotas from the admin side, and for instance set the maximum bandwidth allowed per tenant (cumulative).<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:black'>What do you think about it?<o:p></o:p></span></p></div></div></div></div></div></div></blockquote><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>I’m cautious about this. We’d either need to allow a “Number of DSCP settings” and set them outside the quota or leave it out altogether. Let’s not forget that there’s more than just rate limiting in QoS, and we need to make sure all the options are included. Otherwise, there’s going to be a lot of user and operator confusion as to what is and isn’t considered part of the quota.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>-Anthony<o:p></o:p></span></p></div><blockquote style='border:none;border-left:solid #B5C4DF 4.5pt;padding:0cm 0cm 0cm 4.0pt;margin-left:3.75pt;margin-right:0cm' id="MAC_OUTLOOK_ATTRIBUTION_BLOCKQUOTE"><div><div><div><div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-right:0cm'><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:black'> <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=IT style='color:black'>Regards,</span><span style='color:black'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=IT style='color:black'>Giuseppe</span><span style='color:black'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=IT style='color:black'> </span><span style='color:black'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-autospace:none'><span lang=IT style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:black'>--------------------------------------------------------</span><span style='color:black'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-autospace:none'><span lang=IT style='font-size:9.0pt;font-family:"Verdana","sans-serif";color:black'>Giuseppe Cossu</span><span style='color:black'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-autospace:none'><span lang=IT style='font-size:9.0pt;font-family:"Verdana","sans-serif";color:black'>CREATE-NET</span><span style='color:black'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-autospace:none'><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:black'>--------------------------------------------------------</span><span style='color:black'><o:p></o:p></span></p></div></div><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><br>_______________________________________________<br>OpenStack-dev mailing list<br><a href="mailto:OpenStack-dev@lists.openstack.org">OpenStack-dev@lists.openstack.org</a><br><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev" target="_blank">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</a><o:p></o:p></span></p></blockquote></div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><br><br clear=all><o:p></o:p></span></p><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>-- <o:p></o:p></span></p><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"Calibri","sans-serif";color:black'>Kevin Benton<o:p></o:p></span></p></div></div></div></div></blockquote></div></div></body></html>
