Quad loops (4+4) are sometimes effective. See ip4_lookup_inline(...) and
dpdk_device_input(...) for examples. The limiting factor: gcc runs out of
registers.
I've yet to discover a case where a sextuple loop (6+6) would seem likely to be
effective. Please let folks know if you discover one.

We plan to implement a new node in VPP. I have the following 2 small questions
(1)2 + 2 principle
For each vpp node, first it prefetch the next 2 packets (see the following
codes) and then process the 2 current packets. Do we must to follow this
programming style? Can we do 4+4 or 6+6
I am compiling the load balancing plugin in 16.09 release on an Ubuntu 14.04
bare metal.
I followed the same instructions as for building the sample plugin.

The tuntap-tx node in VPP does not save any data to support packet trace.
That’s why you do see any packet trace after error-punt. -John

Packets on TUN interfaces do not have MAC headers.
You can clearly spot the ip header 0x454e in both cases, and the mac header
ip4 ethertype 0x0800 (ip4) in the ethernet header case.

Yes I saw the packet in tcpdump, however the packets are not getting
received on UDP server application.
In the tcpdump , the packet does not have the Ethernet header as shown
below-

You saw the packets w/ tcpdump, right?

You mean that *ip4-udp-punt *node will directly write to tuntap
interface for sending the packet to Kernel.

For vpp-lite on Ubuntu, the error is; Unable to locate package python-termcolor

Hi,
VPP APIs provide two ways two ways to configure IPFIX.
One is part of the core api - introduced by https://jira.fd.io/browse/VPP-204.
Second one is the one provided by flowperpkt plugin -
https://gerrit.fd.io/r/#/c/3318
Honeycomb team wants to provide netconf support for IPFIX,
which one of
14 matches
