Re: [tsvwg] A word for "does not have a significantly negative impact on traffic using standard congestion control"?

[Lloyd W <[e-mail]>]

What does 'well-behaved' mean in a congestion control context? 
(Hmmm, 3con there for that)

We could write something updatable by later RFCs defining what well-behaved means, describing how it means no significant negative impact, allows
coexistence with Reno and TCP Friendly flows, and we're done. Nuance can be
in the RFC.

Testing has shown that our experimental protocol's performance under
congestion is well-behaved, matching the definition of well-behaved in RFCxxxx

I don't think we should hang Reno or TCP around our necks in the term. (Reno is an
example implementation of TCP, and imo even more specific and not transport
 agnostic)
