Editor's Note: Minutes received 8/14
CURRENT_MEETING_REPORT_
Reported by Gene Hastings/PSC
Minutes of the Network Joint Management Working Group (NJM)
Agenda
o Follow-up on Past Actions
- Matt Mathis' presentation on BGP is available via anonymous ftp
from a.psc.edu as psc-bgp-utilization.ps
- Many operators have adopted the canonical trouble mailboxes
previously discussed in NJM (net-trouble@your.net, net-
trouble@noc.your.net) but the practice is not yet ubiquitous.
Part of the reason is a range of system organization.
- If you haven't submitted an entry to Dan Long's online
phonebook, DO IT!
o Operational Implications of NSF Recompete.
- While it is not yet clear what the impact will be, it IS clear
that the NSF backbone recompete has the potential for great
change in the operations and practices of the Regional Network
Operators. Operations and engineering personnel should be
following the developments and considering ramifications.
- Subscribe to the NSF recompete mailing list:
recompete-request@nsf.gov. Related papers are available on
expres.cise.nsf.gov.
- Look at the papers on expres.cise.nsf.gov, in remcompete/
Aiken-Braun-Ford, impl.ps - Aiken presentation to FNCAC,
Aiken_HPCC_NREN.ps - Draft solicitation.
o Operational Implications of Addressing Changes. Dan Jordt - small
campus given N class C nets, but cannot (or will not) run 8 bit
subnets. router use on same net? ARP hacks?
- How does an operator handle N class C(s) when a site can not or
will not run 8 bit subnets?
- There are numerous tricks, such as ARP hacks/router interface
hacks etc.
- There was agreement of all assembled that there is a need to
1
really explore ways to do this and collect experiences.
Unfortunately, the IP Addressing BOF was scheduled in Parallel,
so discussion was limited. A crossover attendee said that the
BOF was focusing on a recent paper (Rekhter/Li), but there was
little notion yet of what its consequences might be.
o OpStats - Are you doing it? What stands in your way? What help do
you need? Money available for statistics software from FARNET/NSF.
- Action Item - Ittai Hershman volunteered to speak to NYSERnet
about releasing into the public domain the old SNMP software
and relaxing license agreements.
- Several folks complained that there is no statistics gathering
package freely (or cheaply) available. The free SNMP libraries
are only that, and complete packages, where they are
affordable, tend to be highly platform dependent for displays
or for other libraries.
o New Services - How to operate and debug services.
- Do you operate any?
- Do you support, debug them?
- WAIS
- ARCHIE
- GOPHER
- AFS
- Do you need map of logical service topology?
It is the case that network operators are called upon more and more
to troubleshoot services above the transport layer, and a
proliferation of new services to troubleshoot. (DNS, NFS, NTP,
NNTP, BITNET II, WAIS, Gopher, Archie, etc.) There was agreement
that maps of service topologies would be of great value in network
operations, but there were no dramatic ideas on conventions or
format.
o Scuttlebutt
- Tom Easterday of CICnet announced that as of July 1 1992, ANS
is running the CICnet NOC now.
- Observations: What should we do with the T-1 network
connectivity? Matt Mathis observed that the T1-T3
Interconnects seem to be stable and not critically loaded at
present, but what will happen to them if sites peering with
both T# and T1 backbones stop listening to the T1 (this would
send all of their T1 traffic through the interconnects). The
decommissioning of the T1 entirely is contingent on the
availability of CLNP in the T3 backbone, and fallback T1 links
2
for the current T3 ENSSes.
- 192.1.1 (a BBN Network) will be discontinued because some
vendors of medical equipment ship using it as a default host
network.
- Some operators continue to experience random syslog messages
from hosts that have lost a route to their loopback address.
Should operators black hole traffic to 127 net to prevent
wandering syslog messages.
- Caution: SURAnet has seen a CISCO applique (``335'' style)
that will pass even length packets but not odd length.
- There was agreement that [the attending] Network Service
Providers are willing to take on the job of handing out address
blocks if and when hierarchical schemes might be adopted. Some
discussion followed as to whether operators should seek large
block assignments and start handing them out now to get a head
start on things.
