Re: [vpp-dev] TCP performance - TSO - HW offloading in general.

2018-05-07 Thread Luca Muscariello (lumuscar) 
Hi Florin

Thanks for the info.

So, how do you explain VPP TCP stack beats Linux
implementation by doubling the goodput?
Does it come from vectorization?
Any special memif optimization underneath?

Hi Luca,

We don’t yet support TSO because it requires support within all of vpp (think 
tunnels). Still, it’s on our list.

As for crypto offload, we do have support for IPSec offload with QAT cards and 
we’re now working with Ping and Ray from Intel on accelerating the TLS OpenSSL 
engine also with QAT cards.

Using the Linux kernel w/ or w/o TSO I get an iperf3 goodput of 9.5Gbps or 
4.5Gbps.
Using VPP TCP stack I get 9.2Gbps, say max goodput as Linux w/ TSO.

Is there any TSO implementation already in VPP one can take advantage of?

Side question. Is there any crypto offloading service available in VPP?

[vpp-dev] TCP performance - TSO - HW offloading in general.

2018-05-07 Thread Luca Muscariello 
Hi,

 

A few questions about the TCP stack and HW offloading.

Below is the experiment under test.

 

 

  ++  +---+

  |  +-+ DPDK-10GE|   |

  |Iperf3| TCP |  ++  |TCP   Iperf3

  |  ++Nexus Switch+--+   +

  |LXC   | VPP||  ++  |VPP |LXC   |

  ++  DPDK-10GE   +---+

 

 

Using the Linux kernel w/ or w/o TSO I get an iperf3 goodput of 9.5Gbps or 
4.5Gbps.

Using VPP TCP stack I get 9.2Gbps, say max goodput as Linux w/ TSO.

 

Is there any TSO implementation already in VPP one can take advantage of?

 

Side question. Is there any crypto offloading service available in VPP?

Essentially  for the computation of RSA-1024/2048, EDCSA 192/256 signatures.

Hi,
I have used linux iptables for NAT, but now I want VPP nat.

could you please give me some examples corresponding to the iptables one on
how to use VPP nat?

e.g.  iptables rule :  ,vpp rule: yy

Re: [vpp-dev] How to add plugin's statistics into stats thread

2018-05-07 Thread Ni, Hongjun 
Hi Jerome,

We would like to add LB plugin statistics, including per- VIP connections and 
per-AS connections for each VIP.
Frequency is configurable, 1 second is better.
Data of volume depends on the number of VIPs and Ass.
Please refer to below patch for details:
https://gerrit.fd.io/r/#/c/12146/2/src/plugins/lb/lb.api

Thank you,
Hongjun

Hi Hongjun,
Could you elaborate a bit on the kind of statistics you’d like to create?
Frequency and volume of data may be interesting inputs.

Objet : [vpp-dev] How to add plugin's statistics into stats thread

Hi all,

We want to add plugin’s statistics into VPP stats thread.
But it seems that current stats thread only support codebase (i.e. vnet) 
statistics.
Is there some mechanism to support adding plugin’s statistics into stats thread?

Thanks,
Hongjun
