hello
i have a host that sends 100 tcp syn packets per second which every packet has
spoofed source IP and as a result they all will be sent to the POX controller.
as i monitor by Wireshark i see that the first 250s packetIns have meaningful
Bufffer ID value in packetin but then i see lots of
Hi Majid
Your guess is correct.
4294967295 is eqaul to 0x which indicates that the whole packet is
contained in the packet-in message.

Hi Aaron
I'm wondering how to associate a receiving flow_mod message with pending_upcall
list? Is there a change to use "cookie" field in packet_in/flow_mod messages?

Hi,The problem doesn't seem to happen with latest ovs 2.5.0 git branch (commit
ac93328273238b5dc8635364fa4f30ad95e8, dpdk 16.04).
This is the stack traces we got with 2.5.0 release:

I had the same issue some time ago. Probably you cannot use Mininet tc and
ovs queues together, because both are based on HTB. There is a conflict.

It breaks LLDP:
Thanks Giuseppe and Ben for your answers.
Giuseppe, did you find a way for having queues and delay at the same time
with mininet and ovs? Thanks again.

What does "the p
To send packets to the kernel, output them to an internal port, such as
the port named after your bridge.

What does it mean to "output the response of the kernel"?

Hi,
My name is Da Yu. I'm building a prototype in Mininet. Now, I have trouble
in measuring performance with Iperf.
My Mininet Version:

2.1.0
My OVS Version:

ovs-vswitchd (Open vSwitch) 2.5.0

Here is my topology:
h1(eth0)-
What if we just make ofp_port_t 32 bits? That has to be the long-term
trend anyway because OpenFlow 1.1+ uses a 32-bit port number. The
following passes all the unit tests on i386 (though I haven't carefully
looked at all the uses of ofp_port_t), what about big-endian systems?

I don't know why arp replies wouldn't work. Ordinarily they work fine.
