Yes, the first option will be easier to implement. For the second option,
yes you are right. Implementing a dpif provider as Justin suggested is
also be a very good choice. Really depends on your design goals.

i think the first option may be implemented more easily, in which i just
implement the datapath kernel module.
and in the second option, do you means that the whole project can be ported
to SE mode(including ofproto and vswitch)?

If you simply want a faster datapath implementation, you may want to
consider just optimizing the kernel datapath code using OCTEON SDK APIs.
As you may already know, most of the SE API are ported the kernel as
the base APIs for OCTEON NIC driver. This approach will allow you to speed
up datapat
Using SE, I would imagine you'd implement a datapath there. In the Linux core
running ovs-vswitchd, I would imagine you'd implement a dpif provider that that
spoke to the datapaths running in your simple executive cores.

In the SE mode, i must implement the datapath module, dpif provider and
dpif as showed in the graph without other module changes, is this right?
right now i'm on the stage of doing some research and experiments, i
prepare to accelerate OVS. then, maybe used in campus network in future.
what i want
Please keep this on the list.
I'm somewhat familiar with Cavium's platforms. One option would be to bring up
the cores in Linux, and I think you could run the kernel module essentially
unchanged. Another option, which would be a lot more work but would almost
certainly be faster, is to port d
What operating system and platform are you porting it to? The ofproto provider
pushes flows that have wildcards, and are very similar to OpenFlow flows. The
dpif provider only pushes exact-match flows. If you have access to something
like a TCAM that supports priorities and wildcards, then im
i have some question about PORTING file. there is a graph in this file as
follow:

now i am willing to port the source code to a network processor ,which is
MIPS arch. my goal is implement the kernel module in the platform.but i
still cannot figure out a clear procedure about it. whi
