[ih] Secret precedence schemes back then

[Matthias Bärwolff]

Hi,

I have come across two sources briefly pointing to the secret precedence
scheme implemented with NSFNET's Fuzzball routers aimed at giving
priority to telnet over other less time sensitive apps. (Mills:
http://doi.acm.org/10.1145/52324.52337, and also: Bohn et al, 1994,
Mitigating the Coming Internet Crunch: Multiple Service Levels Via
Precedence)

Does anyone know of further literature sources dealing with those
schemes and, specifically, how they developed in time and beyond NSFNET.
What about the practices of private ISPs up until today, maybe there are
some scholarly accounts out there about the general picture and history.

I appreciate your help.

Thanks
Matthias
