[e2e] current congestion control specs?

In response to your requests:

(1)  RFC 2001 has been obsoleted by RFC 2581 (which, from what I 
understand, is geared more towards an implementor's POV)

(2)  SACK is a fairly good loss recovery scheme, and it's implementation is 
growing [See M. Allman, "A Web Server's View of the Transport Layer", ACM 
Computer Communication Review, 30(5), October 2000] so it would be good to 
include it in any implementation of a network stack.  SACK is defined in 
RFC 2018 and extended in RFC 2883.

(3)  I have not read RFC 2914 yet either, so I cannot provide feedback on 
that, but perhaps someone else can?

Hope this helps,
