Thanks, James, Tim Agreed. That additional text in the abstract didn't add good value *sigh* Can i ask whether you are using PIM-SM or Bidir-PIM for these type of apps ? Always particularily curious about how well PIM-SM with bursty sources does work well (or not) in different scenarios. E.g: Do you think that RFC 8364 would work equally well for your app environment ? Cheers Toerless On Fri, Mar 30, 2018 at 10:19:14PM -0500, James A.
