Meter Rate Limiters

[srisiv]

Hi,

I am trying to rate limit the traffic matching certain flows. I am using the HP VAN SDN controller version 2.0.0 and a hp 2920 switch. I initially tried using OpenFlow 1.3 and was able add flows (without meter instructions) and a meter limiter. However, while I was able to add a meter id instruction to the OfmMutableFlowMod, I got an unsupported instruction error when I checked the result via a MessageFuture after sending the Ofmflowmod. There was no exception thrown by the controller. So I checked the HP2920 documentation and it says it supports rate limiters for OpenFlow 1.0.

So now if I were to re-write the code for the HP application using OpenFlow 1.0, how do I associate an OfmMutableFlowMod with a rate limiter id?

Thanks and Regards,

Sridhar

PS: Would you be aware of any HP switch models that support meter rate limiters for OpenFlow 1.3?

Hello Sridhar,

Please have a look on the cases mentioned in below links see if this helps.

Also please check the Controller Java API docs version 2.0 there is a package com.hp.util.rs.rate  which has two classes AbstractLimiterFilter and RateLimiter.

Please let us know if this solves your problem or you still face some issue.
