-
- Instead of putting actual copies of maps into central repositories,
- pointers as to where to get the maps should be placed there. This would
- make it easier and quicker to update maps, since the network manager
- does not have to distribute maps, just update the local copy.
-
- It seems as though the very bade traceroute has disappeared from many
- peoples' list of tools. Matt Mathis said that it appears that
- traceroute is included in Ultrix 4.2, although it is unknown whether it
- does third party or not. Sources for traceroute are available via
- anonymous ftp from ftp.lbl.gov (may not include the third party mods)
- and from nic.near.net (in the pub or src directory).
-
- Also, Matt M. provided some examples of traceroutes into the backbone
- that failed. The common denominator being that if the endpoint or the
- corner of the third party traceroute is in the backbone, it will fail.
- Merit says that this may be by design.
-
- Merit/ANS discussed their architecture plans for the CNSS [see also
- slides from the plenary technical presentation by Elise Gerich and
- Jordan Becker - EFH]. Currently, they decrement the TTL through the
- routers, but would like to make the CNSS's in a POP appear to be one
- router by only decrementing the TTL on entry or exit. This would make
- the separate CNSS's invisible. One point against this is that in a
- tightly coupled FDDI, this could create a giant loop. (??) Merit also
- said that future cards will receive routing updates from the CPU.
-
- Fallback paths were also discussed. (In particular fallback paths of
- lower capacity) Some important points were that if a backup path exists,
- then it should be carrying some traffic all the time, so that the backup
- path's status is known at all times. Backup paths of lesser capacity
- can easily be flooded by production traffic, so some means of limiting
- traffic must be made. Things like mail can be MX'ed to the backup path,
- and all other traffic could be blackholed.
-
- As nets become faster, monitoring is becoming harder. Merit is
- currently using periodic sampling of 1 in every 50 packets on the T3.
- Merit would like to use a more stochastic process. More work needs to
- be put into this to determine a more accurate sampling process.
-
- With more and more nets appearing, some better method of reporting
- outages is needed. An outage of a campus with large nets could easily
- flood people. A template for reporting outages is needed, so that a
- database can parse these messages and store the information. Thus, one
- need not even read the mail, but query the database for the net in
- question.
-
- Merit is working on something like this for trouble ticket tracking.

- Since high schools are entering the internet, two problems are
- occurring. Under what name should the schools appear. (us or edu)
- Also, how do we get them started? Nearnet offers a full service option
- for new people, that completely orients the newcomer. User Services
- should also target the end user and not just the network operators.
