RSS is a way to distribute packets to multi cores while packets order in
the same flow still get maintained.
Round robin distribution of packets may cause ooo(out of order) of packets
in the same flow.
We also meet this problem in ipsec vpn case.
The tunneled packets are rss to the same queue if t

Hi,
If the traffic you manage is above MPLS or GTP encapsulations, then you can use
cards that provide flexible hash functions. Chelsio cxgb5 provides combination

Hi Bryan,
Regarding your 1st point, the single core becomes the rx bottleneck which is
clearly not desirable.
I am not sure regarding how to use the stuff you mentioned in 2nd point, is

Round robin would actually be awful for any protocol because it would cause out
of order packets.
That is why flow based algorithms

Hi,
As far as I can tell, this is really hardware dependent.

Hi Michael,
As far as I know, RSS is used to distribute packets between cores based on
hashing the packets' initial bytes, so round robin distribution is not
possible in hardware. You can configure the hash seed and which fields to
use in the hash. If the input packets have same or very similar by

Hi all,
I am writing a dpdk application that will receive packets from one
interface and process them. It does not forward packets in the traditional
sense. However, I do need to process them at full line rate and therefore
need more than one core. The packets can be somewhat generic in nature a
