Re: [vpp-dev] flowtable plugin

Hi, I updated the flowtable on github and on vppsb (in review) to take all these remarks into account. The flowtable had some dependencies on the test node I used (portmirroring) which should now be fixed. It should be completely independent now. I

Thanks Damjan. I'll keep those examples in mind to make sure nothing bad can happen. On 11/25/16 14:09, Damjan Marion wrote: > As long as you have good understanding what nodes in the middle are doing you > should be fine. > > Likely most complicated case is with node A before FIB lookup and no

Re: [vpp-dev] flowtable plugin

As long as you have good understanding what nodes in the middle are doing you should be fine. Likely most complicated case is with node A before FIB lookup and node C after. FIB might send your frames to different encap nodes which may overwrite opaque, one candidate is definitely ipsec which

Re: [vpp-dev] flowtable plugin

The flowtable uses the opaque buffer for two things: - it provides a flow id, and a flow state - it provides an opaque buffer to be filled with information external to vpp (which in my case is dpi metadatas, but it could be anything) using the binary API. So the flowtable (node A) alone will provi

Re: [vpp-dev] flowtable plugin

both opaque and opaque2 are shared resource. There is no guarantee that node in the middle will not overwrite it. Is your situation really a case where node A needs to send some information to node C and there is unknown B or many Bs in the middle? > On 23 Nov 2016, at 15:15, gannega wrote:

Re: [vpp-dev] flowtable plugin

Thanks for the explanation. So I can use anything I want within the opaque buffer as long as I don't presume what happens next. And ... I'm actually doing things I should not in the flowtable (which wasn't obvious to me until you explained it that way) ... so I'll go fix that. Thanks again, Be

Re: [vpp-dev] flowtable plugin

Hi Keith, This is a kind reminder. Also, I stumbled upon VPP-320, and especially https://gerrit.fd.io/r/#/c/1676/ which adds a 6 Bytes of plugin_metadata in the opaque1 union, which has been reopened for nsh-proxy. I feel this might be a good way to go which would ensure no collision between the

Re: [vpp-dev] flowtable plugin

Hi, One question for Keith first: The flowtable currently uses the first opaque field as a buffer to store the data associated to the flow, but Andrew told me today that you advised against this kind of behavior. The idea is that the flowtable is configured to redirect packets to a working node

Hi Andrew, I work in Paris, so we're in the same timezone, and of course i'm interested to discuss all this with you. I'll update github with the current state of my work, and look at your plugins so that I understand what you did a bit before. I'm working on this with Christophe Fontaine (added

[vpp-dev] flowtable plugin

Hi, I'm currently working on writing a flowtable node for vpp (It can be found in vppsb or on github ). In short, it inserts itself between given interface and ethernet-input, and basically provides a buffer associated to the flow which can be writte
