Re: [vpp-dev] VPP with DPDK eventdev

[Dave Barach]

As things stand: handling packets from the same flow on multiple worker threads 
will cause packet reordering. That's not acceptable. 

The algorithms required to avoid that result are known, but end up performing 
significantly worse than sending all traffic from a single flow to a specific 
worker thread.

Data from real networks always reacts well enough to h/w or [worst-case] s/w 
flow hashing. I have to confess a lack of interest in single-flow-tuple traffic 
generator test-case performance. 

HTH... D.

Can eventdev inspire VPP to process packets from the same flow across multiple 
CPUs?

I’m not aware of such activities, but before you start working on the actual 
implementation i would suggest community discussion on architecture, use cases 
and required changes in the code. Biweekly community call is likely good forum 
for that.

[vpp-dev] VPP with DPDK eventdev

[Andrew Pinski]

Hi all,
  We were wondering if anyone is currently working on getting VPP to
work with the DPDK eventdev?  We don't want to duplication.

Thanks,
Andrew
