The Cisco PIE too has been standardized by docsis meant to be for cable modems I think we would have similar concerns for switches and routers. (E.g. cat3k switches or Cisco 5760 controllers just to name) I would like to know your views about what you think about it . Are the theories so far and the AQMs (codel and pie) stand true for such devices too? What would it take to measure the bloat levels of these devices? Do we still need to use the netperf wrapper to get the characteristics of such devices?

Hi,
We have been talking about the bloated buffers mostly on the home routers. = The Cisco PIE too has been standardized by docsis meant to be for cable mod= ems

I think we would have similar concerns for switches and rout= ers. (E.g. cat3k switches or Cisco 5760 controllers just to name)

I would like to know your views about what you think about i= t .
Are the theories so far and the AQMs=C2=A0 (codel and pie) stand true for s= uch devices too?

What would it take to measure the bloat levels of these devi= ces? Do we still need to use the netperf wrapper to get the characteristics= of such devices?

Thanks
Ketan
