- N-1-1-040.50 Cooperation Among Network Operation Centers - A
- Beginning, by Elise Gerich*, <epg@merit.edu>
-
-
- In the summer of 1988, when the NSFNET T1 backbone became operational,
- the NSF mid-level networks and the NSFNET management team discussed
- the need for the distribution of real-time information about the
- status of the NSFNET backbone. The mid-level networks provide direct
- support to the network users within their region or organization. The
- users call the mid-levels when they perceive a problem reaching
- someone or some machine via the network. The network is and should be
- perceived as one entity; the multiple component networks that provide
- the path from one destination to another should be transparent to the
- user. Therefore, the network operation centers which are responsible
- for various portions of "the network" need a way to share information
- about the health of their portion of the network.
-
- The result of these discussions was the creation of a mailing list,
- network-status-reports (nsr@merit.edu). For the last three years the
- Merit Network Operation Center has posted notices of scheduled
- backbone activity and disruption of service on the backbone to nsr@
- merit.edu.
-
- The mid-level networks agreed to create distribution lists for the
- network status announcements. The Merit Network Operation Center used
- this mailing list to apprise the NSF regionals of the status of the
- NSFNET backbone. Some of the mid-levels, notably JVNCnet, also
- started to use nsr as a vehicle to notify other network operation
- centers of activities within their regional network. However, the list
- has primarily reported information about the NSFNET backbone.
-
- As more and more networks accessed the NSFNET and the NSF regionals,
- the original distribution list has expanded to include more network
- service providers, for instance, CA*net, SWITCH, and EASInet.
-
- At the Network Joint Management working group meeting at the last IETF
- in Santa Fe, New Mexico, the usefulness of sharing information
- concerning the status of the Internet was discussed. From all
- reports, the working group agreed that the network operation centers
- need to know what is happening in remote parts of the Internet that
- may impact the ability of their users to access some destinations.
- This sharing of information permits the network operation centers to
- more efficiently debug problems reported by their constituents.
-
- The working group also agreed that while the nsr mailing list acts as
- a good vehicle for dispersing operational information to other
- centers, it is inappropriate to use that vehicle as a forum to discuss
- meta issues. The integrity of the mailing list should be maintained so
- that network operators can keep the real-time network messages
- separate from other topics.
-
- A second mailing list should be used for on-going discussions
- concerning cooperation between network operation centers. The working
- group proposed that the njm@merit.edu mailing list is the appropriate
- forum for other topics concerning distributed management of the
- Internet.
-
- Network Operation Centers are encouraged to use nsr@merit.edu to
- notify other NOCs of scheduled maintenance and other service
- activities for which they are responsible. Accurate and timely
- postings by NOCs to nsr will benefit all of us in serving our users.
