[ovs-discuss] Adding a new action to OVS

Hi, I am working on a research project, and I have to add a datastructure to the kernel module to perform some statistics on the incoming packets. To do this in a nice way, I wanted to know how I can add a custom action in the flow rule to direct packets to the code I write (which will then updat

Hi Han, I am using Openstack with vXLAN & see the performance 2.x Gbps throughput over the 10Gbps line. I see in the below link that you were facing the same issue & after tuning some parameters, you could go upto 6Gbps. It would be great if you can share those tuning parameters? I have configured

[ovs-discuss] why does my packet VLAN ID get changed?

Please help me debug this problem. I have an OVS with two ports. A packet enters the bridge with VLAN 103 and leaves with VLAN 3. I do not understand why. There seems to be no flow rule for this. It should not be changed. This is an OpenStack environment, but I'll try to show the relevant parts. I

I think you'll have to work out these problems yourself, or find someone else to help you. I still have no idea what h1-eth0 or h2-eth0 is or how they relate to anything. On Fri, Aug 01, 2014 at 03:37:13PM +0100, Bruce SUN wrote: > Hi Ben, > > I am sorry fo rmy spell mistake. It is h1-eth0. My s

Hi Ben, I am sorry fo rmy spell mistake. It is h1-eth0. My simple topology is as follows: [image: Inline image 1] After starting openvswitch, I add eth0 (internet interface) to the openvswitch. Then run the command "ifconfig eth0 0.0.0.0" to make eth0 as an openvswitch port. Next run the comm

[ovs-discuss] DSCP Handling

Hi all, I have a question regarding how OVS handles DSCP values. I apply different DSCP values to 2 different UDP flows but it doesn’t seem that the flow with DSCP value 46 (Expedited Forwarding) is treated preferentially than the other flow with DSCP value 0 (Best Effort). Do I have to make ex

Dear Nick, With your explanation, I tryboth commands, and I get the same result when I use "sh ovs-vsctl list NetFlow". The targets is just the same, ["192.168.1.2:5556"]. With "list Bridge", I can see that the switch s1 was netflow enabled with both commands. mininet> sh ovs-vsctl list NetF
