Hi Hiroaki KAWAI Thanks for your prompt response. It helps me a lot :)
1. Although I do not have the clear idea about the NXM_NX_PKT_MARK, I have understood from my reading of the nicira extension that there is a possibility of packet marking. Would you please inform me specifically which openflow message of the nicira extension can be used to mark the data packet ? 2. Regarding the set_field action: thanks to show the second alternative approach. Following link also tells the same. http://www.brocade.com/content/html/en/configuration-guide/fastiron-08040-sdnguide/GUID-6DD519A6-EF27-489D-B78B-EC310287A05E.html But, I am searching one example in which set_fieldAction command has been used to mark the data packet to get the clear idea. Do you have/know any references ? thanks again, and again, Hiroaki. Honestly speaking it helps me a lot :) -Tanvir ------------------------------ Message: 2 Date: Fri, 1 Jul 2016 21:08:50 +0900 From: Hiroaki KAWAI <[email protected]> Subject: Re: [Ryu-devel] mark the data packet To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=iso-2022-jp; format=flowed; delsp=yes Hi Tanvir, Then, we're talking about Linux specific sk_buf.mark, not a packet marking in general. In ryu library, you can find NXM_NX_PKT_MARK in ryu/ofproto/nicira_ext.py, and it should not be hard to use. https://github.com/osrg/ryu/blob/master/ryu/ofproto/nicira_ext.py#L385 BTW, set_field action to metadata field can be used to mark a packet as far as the packet is traveling in openflow pipeline. ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
