I believe the work was done by BellCore for ANX. It was done by the folks at the Internet Architecture Research Lab in Morristown, NJ. You might try contacting somebody there...

11 Jun '97

Anyone remember the RFC# that details the suggested email user names for specific operations? i.e. dns-admin for DNS, abuse for Abuse, postmaster for mail problems, noc for technical problems and requests, and peering for peering request/problems etc. If anyone remembers what is is, could you please email it to me? (I do not wish to furthur muddle up the list.) Thanks in advance! Cameo

Ascend GRF
by Peter Leppik 11 Jun '97

11 Jun '97

I've been hearing conflicting stories about the Ascend GRF lately. Cisco claims that it doesn't really work as advertised in "realistic networks," but Ascend says this is because Cisco's routers melt down when the GRF feeds them routing table updates, so the GRF has to be throttled back to work in a mixed environment. Does anybody have any real experience here? Any information, pointers, anecdotes, or wild rumors would help. Thanks, -Peter

At the Tampa NANOG someone commented that the ANX document calling out the network metric specifications was now available (for purchase) from them.

Might I suggest that a new group be set up to discuss and handle operational issues? Clearly this is no longer it... and this list has no value if we keep having to dig through the manure to find the pony. I'm getting more spam from this list than I'm bouncing from AGIS.

Re: Ascend GRF
by Daniel Senie 11 Jun '97

PSI used to feed our site with a Cisco 7xxx and changed to a GRF400. The OpenROUTE Networks RBX250 router we use to talk to it had no problems with either. Actual packet throughput appears to be improved since the router was swapped, which I assume was the reason for the replacement. I haven't noticed a substantial difference in the speed with which the advertisements roll in. Either upstream box pumped out the BGP advertisements when the line first comes up at about 60% of the T1. Neither box pushes harder than that. There were some problems (non-BGP) when PSI first tried to activate the GRF, but those appear to have been resolved.
