I agree that an update should be done prior to publishing the Node
Requirements draft, but I have some issues with the language (not the
intent) proposed below...

Hi all,
There has been some discussions whether or not we should add support for the
Flow Label in
Soon to be RFC 6434<draft-ietf-6man-node-req-bis-11.txt> As a straw man
proposal, if we add
Support, I would suggest the following text:
All nodes SHOULD support RFC 6437, IPv6 Flow Label Specification,
defines the IPv6 Flow Label. Specifically:
"Forwarding nodes such as routers and load distributors MUST NOT
depend only on Flow Label values being uniformly distributed. "
"It is therefore RECOMMENDED that source hosts support the flow
label by setting the flow label field for all packets of a given flow to
the
same value chosen from an approximation to a discrete uniform distribution.
"
First, I propose that the text be added to section 5.1, which discusses
the specifications that must be supported at the IPv6 layer. Second, I
would modify the text proposed to clean up the introductory component as
follows:
All nodes SHOULD support the setting and use of the IPv6 Flow
Label field as defined in the IPv6 Flow Label specification
[RFC6437]. Forwarding nodes such as routers and load distributors
MUST NOT depend only on Flow Label values being uniformly
distributed. It is RECOMMENDED that source hosts support the flow
label by setting the Flow Label field for all packets of a given
flow to the same value chosen from an approximation to a discrete
uniform distribution.

Brian (who is not wearing any hats at this time)
