Ben,
Thanks for the response.
Have few follow-up questions, am using ovs 2.5.
1) "group_best_live_bucket()" function - Is this function traversed in
control path everytime when the data path flows inside kernel expire?
2) In this method, if a new bucket is added with higher weight, there is a
go
No, select buckets don't use mod-n to select a bucket. Instead, for
each live bucket, OVS hashes flow data with the bucket ID and multiplies
by the bucket weight to obtain a "score", and then selects the bucket
with the highest score.

Hi ben,
Let me rephrase.
Does hashing involve mod on number of buckets in a group ? If a new bucket
is added/deleted in a group, would it result in different hash value and
hence a selection of different bucket for the same 5 tuple ?
Also, how many buckets per group does ovs support ? And how man
