[vpp-dev] VPP TCP hoststack performance data #vpp-hoststack #vnet
Hi, Is there any place where I can find VPP host-stack TCP performance data -- like MPPS and throughput data. I couldn't find it in CSIT website.

[vpp-dev] VPP Hoststack CPS
Hi, In the slide deck at https://wiki.fd.io/images/b/b4/Vpp-hoststack-kc.pdf I see that with VPP Hoststack 200k CPS is achieved. Have few questions: a. Are the sessions originated from App linked with VCL? b. Is the TCP connection over the network or on local host? b. Non-blocking connect fixes are available only recently. Were the results with blocking connect()? Thanks in advance. -Nataraj -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] UDP packet sending using sendto()
Hi, Today with VPP we cannot give endpoint info in sendto() call. We have to do a connect(udp_sock, endpoint_info) first and then invoke sendto(). This works. But the question is how can I influence the source port of these packets? Thanks, -Nataraj -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] setsockopt with TCP_NODELAY
Hi Florin,
Thanks for reply. My question is setsockopt() for not yet established
sessions i.e before connect(). I was trying to clearing TCP_NODELAY,
setting TCP_MAXSEG(to much lower than interface MTU) and TCP_KEEPINTVL.
These options need to be communicating to the vnet right? I was looking
for that.
Thanks,
-Nataraj

[vpp-dev] setsockopt with TCP_NODELAY
Hi,
I was trying to use TCP_NODELAY socket option in my application. But I see that
relevant code is "VPP-TBD" in vppcom.c. I see same comment for most of socket
options. Is there any other branch where code is available? If not, are there
any plans to support setsockopt that involve communicating VPP TCP core.
case VPPCOM_ATTR_SET_TCP_NODELAY:
if (buffer && buflen && (*buflen == sizeof (int)))
{
/* VPP-TBD */
if (*(int *) buffer)
VCL_SESS_ATTR_SET (session->attr, VCL_SESS_ATTR_TCP_NODELAY);
else
VCL_SESS_ATTR_CLR (session->attr, VCL_SESS_ATTR_TCP_NODELAY);
VDBG (2, "VPPCOM_ATTR_SET_TCP_NODELAY: %d, buflen %d, #VPP-TBD#",
VCL_SESS_ATTR_TEST (session->attr, VCL_SESS_ATTR_TCP_NODELAY),
*buflen);
}
