Profile for HEP Internet Monitoring Talks
Les Cottrell
(SLAC) and
Paul Jeffries (RAL),
Last Update: 20 March, 1997
[
CHEP97 |
Mini Workshop on HEP & the Internet |
Agenda for afternoon Monitoring session
]
The plan is to have brief (15 minute) reports from various countries. In order
to maximise the effectiveness of these reports, we recommend:
- The reporters give presentations based on a 'profile'.
- Reports (probably just their URLs) are submitted to
Les Cottrell
in advance of the meeting,
and if possible by 1 April 1997 to be published on the Web.
Don't worry too much about the report being complete, it is fine t
o continue to update it as more information comes in. Les will
provide a link from the
Mini Workshop Web page to the
reports as they
come in.
The profile is given below. The aim is that we all supply the same
information. This facilitates comparison, and leads us in the direction of
being able to grade connections in a consistent manner. See
SLAC's HEP Internet Monitoring for an
early example of a report.
Proposed Profile:-
- List international connections you have giving bandwidth and protocols
supported.
Also list major "offsite connections", as most sites in the US do not link
to international connections directly.
- Summary of local monitoring of Internet connections that you undertake.
Useful Web addresses. Types of measurements made and tools employed.
- Definition of list of "connections" on which you propose to publish
monitoring results. We suggest that the list includes connections from
your own site (and/or country) to key particle physics centres (mainly
accelerator centres) and other sites with whom you collaborate. We feel it
is necessary to identify a subset in this way as opposed to publishing
every conceivable connection that you can monitor!
- Attempt to rate the connections:
- Interactive qualification. We propose for Internet links:-
Ping Packet Loss | Quality |
0-1% | is good quality |
1-5 | is acceptable |
5-12% | is poor |
12%-25% | is bad |
> 25% | is unacceptable |
This would be the first step in unifying both our measurement procedures
and our ratings.
- Average FTP over a defined period (in Bytes/sec), or other (non Ping)
measurements on performance.
- Summarise the off-site/international networking changes you foresee
in next 12 months (upgrades, or becoming part of new backbone eg TEN-34)
- Summarise the resources you have available for Internet network monitoring.
This includes people working on it, and tools you are interested in making
publicly available. In addition the location of any remote
traceroute servers, the addresses of 24hrx7day
hosts (say for pinging), names of contact people etc.
Thankyou!
