]]> Comment on Self Similar Nature of Ethernet Traffic by Aldrin Isaac http://siwdt.com/2013/05/07/self-similar-nature-of-ethernet-traffic/#comment-1154 Sat, 11 May 2013 18:29:09 +0000 https://siwdt.wordpress.com/?p=1325#comment-1154 Affinity based approach to dealing with self similar nature of traffic makes assumptions about the physical placement of endpoints on a network, the scale of the system and the ability of a network controller to react in time to make a difference. A bigger issue in my experience is not of the self-similarity of Ethernet traffic, but the affect of long lived high bandwidth flows on shorter lived flows. For this problem there are evolving active queue management schemes such as http://www.ietf.org/proceedings/86/slides/slides-86-iccrg-5.pdf as well as indeed affinity based approaches such as http://cseweb.ucsd.edu/~vahdat/papers/helios-sigcomm10.pdf.

jumping ahead of Bill here, your thoughts are very much aligned with our thinking and the possibilities (dare I say vision) of the Plexxi solution. There will be overlay solutions and there is no reason that Plexxi cannot provide the exact same network services based on overlay endpoints (better yet, the overlay identifier) as an aggregate of applications…

With many orgs having separate people in charge of the network and apps/virtualisation, I think it would have been great if there was an option to integrate OVS/NVP with Plexxi. OVS (ran by apps/virt ppl) would provide apps/virtualisation admins means to create/change their networks (overlays), while Plexxi (ran by networks ppl) would provide OVS with multitude of transport services (“such as low latency, jitter sensitive, bandwidth, hop count, path”), over which to run tunnels. Instead of actual applications talking to Plexxi diectly, OVS would talk to Plexxi on their behalf to get access to the transport with the characteristics the services it provides to applications need.

I realise this isn’t what Plexxi’s vision is, but I’m hoping you can see the point.

Cheers,

– Dmitri
