Hi Ramki,

If you search our past work proposals,  draft-manral-...
proposed energy efficiency metrics and benchmarking.
There is some controversy and complexity on making power
measurements, we need to collect these issues and see what
can be done.

Additionally, it would be worthwhile to discuss the common energy efficiency aspects across all VNFs. These would include discussing the tradeoffs between CPU energy efficiency/latency/throughput for various packet processing schemes such as

-        Fixed polling

-        Adaptive polling

-        Changing processor P-states (this could be platform specific)



Thanks,

Ramki

Hi Bhavani,



- do we need to consider or compare performance with the real/physical network vs. the virtual network

- in 3.2 do we need Virtual Switch



[MD] We do need to provide methodologies to benchmark for three architectures vSwitch/SR-IOV and PCI bypass.

Regarding comparing performance only PCI bypass can be compared with physical world.  Again we are not benchmarking networks here but the virtual appliance and wherever needed comparison will be laid out for both Physical and virtual appliance.



for 3.2 how about load balancers, firewalls - do we need to consider, what kind of DPI

    - firewalls - stateful vs stateless

[MD] Virtual appliance is broader term - it means virtual Load balancer  and firewalls (both state full and stateless) We won't be suggesting "kind of DPI" - Standard method will be provided to qualify appliance for any type of DPI



Regards,

Muhammad

Al,

    including the WG list also for my comments/Qs for this draft. These are a few things which we can look into including as considerations for this draft.



- also for 3.2 - for VNF itself, do we need location of the VNF - guest VM,separate process, appliance etc

-

    - what kind of considerations we need to note when testing a Virtual Firewall Function

- how many Tenants can a VNF support?

- for 3.3 - how about VM mobility or VNF mobility itself





thanks,

Bhavani
