RE: draft-wang-6man-flow-label-reflection

Hi, Jeroen:

Service Provider wants to apply the same policy to the upstream and
downstream of one session, or more accurately, apply the policy to
downstream of one session based on the recognition of it upstream packet.
The flow label can be used to identify the unique session between one pair
of IPv6 hosts, and alleviate the burden for the network device to recognize
the downstream packet, for example, http response packet. We think this is
one appropriate use case for the flow label.

Best Regards.

As the load balancing use case is the number one reason for the Flow Label
to have an existance, which other use cases would that be?

Greets,
