- CURRENT_MEETING_REPORT_
-
-
- Reported by Gene Hastings/PSC and Dan Long/BBN
-
- Minutes of the User Connectivity Working Group (UCP)
-
- Summary
-
- A presentation on the UCP work-in-progress was made at the Farnet
- meeting on Monday. Useful discussion ensued and continued in the ORAD
- meeting Tuesday. The consensus was that the UCP work is important and
- should be actively pursued so that initial implementations are in place
- in the next 6-12 months.
-
- Encouraged by good suggestions and the support of Farnet and ORAD, the
- UCP group met twice and made good progress on these three projects:
-
-
- 1. A NOC PhoneBook
-
- o Reviewed collection efforts to date
- o NEARnet database forms-based entry being used
- o 22 NOCs have registered so far
- o Suggested new fields and formats (now incorporated in database)
- o Will advertize to wider audience soon
- o Plan to distribute PhoneBook with a finger-based search tool
- o All searches will also return caution that info is for NOCs
- only
-
- 2. Standardized Network Status Reports
-
- o Developed a syntax for standard email-based outage reports
- o NOCs will generate these reports which will contain info about
- current, past, or planned outages
- o These reports will be sent to a mailing list which anyone can
- subscribe to
- o People can develop their own tools for parsing and providing
- interactive access to this information
- o Ideally, end-users and NOCs could use such tools to get more
- information about connectivity problems
-
- 3. Standardized Trouble Ticket Handoffs
-
- o Revised the UCP Trouble Ticket Tracking draft to allow Network
- Service Centers to limit who they are required to accept calls
- from (from last meeting)
- o Network Service Centers will hand off tickets to other Network
-
- 1
-
-
-
-
-
- Service Centers but will stay in the loop with the reporting
- user
- o Developed a syntax for standard email-based trouble ticket
- handoffs between Network Service Centers
- o Several groups are interested in participating in trials of
- this system

- DETAILED NOTES of the 11/19 meeting (first of two) by Gene Hastings
-
-
- The Distributed Agenda (roughly)
-
-
- o Status
- o NSC Phonebook
- - NISI
- - Current
- - Future
- o Reducing Need for Tickets
- - Notification Schemes
- - Database of Network Status
- - New Working Group?
- o UCP Ticket Sharing
- - What Information to Exchange
- - Method/Format for Exchange
- - Implementations
-
- Dan Long (NEARnet) gave an overview of FARNET's interest in UCP
- topics.
- NSC Phonebook - as of the meeting, there were 18 entries in the
- pilot NSC Phonebook. Note was made of the parallel NISI effort to
- collect similar listings for NICs. Vikas Aggarwal (JvNC)
- recommended that contact information be included in DNS TEXT
- records.
- The present NSC Phonebook Database is in Informix. Dan Long
- volunteered to continue to maintain it and to deploy a finger
- <keyword> query agent for it. Dale Johnson (Merit) offered a
- second Informix host for it if someone else would maintain the
- actual db.
- Vikas volunteered to produce a DNS entry template.
- Group consensus was an acknowledgement that these are interim
- efforts.
- Reducing the need for tickets - that is, reducing the need for
- calls from users which require the opening of tickets. This might
- be secured through:
-
- 2
-
-
-
-
-
- o Notification Schemes
- o Database of Network Status
- o End-User diagnostic tools
-
- These are all in keeping with the idea that if users are better
- informed about the state of the world, and have easier means of
- learning for themselves the nature of difficulties, they will have
- less need to call and talk to a person. An example of this at a
- department or campus level might be a bulletin board which lists
- scheduled outages and includes explanations of what services will
- be affected, along with pointers for further inquiries and help
- files explaining the nature of some classes of failure
- A strawman proposal was made to distribute email with a standard
- format, initially based on the NEARnet trouble tickets. Discussion
- followed as to which problem this proposal was intended to solve.
- Uses for standard format mail include: ease of information
- extraction when read; ease of parsing for inclusion in a database
- or for triggering alarms; assurance of completeness of information
- in report; and the possibility of making many reports
- machine-generated. Desired fields were felt to include:
-
- o ASN#
- o Net#
- o Net Name
- o Host Address/NSAP
- o Host Name
- o Affected protocol or service
- o Start/End Date & Time
- o Responsible Person or NOC
- o Ticket Cross-reference
- o Last Update
- o Reporting NOC
- o Perspective/Scope
- o EXPLANATION
- o FURTHER EXPLANATION
-
- There is still confusion and some disagreement concerning what
- things are or aren't tickets. There was, and will continue to be,
- discussion on use, control and interpretation. For example,
- whether these messages should be intelligible to, and distributed
- to, end users.
- Michael Patton (MIT) observed that poorly formed information
- distributed to the public would generate more calls, not less.
- Ittai Hershman (ANS) reported that nsr
- <network-status-reports@merit.edu> is now carried in a PSI
- newsgroup, so the mechanism for end-users to see those messages is
- in place.
- Further work on mail format was deferred until the meeting of the
- 20th.
- Discussion returned to the NSC Phonebook. New fields to add to
-
- 3
-
-
-
-
-
- listings:
-
- o Administrator to escalate to
- o Domain name of NOC
- o Bigger net # field (allow listing of multiple net numbers)
- o Cross references to other nets, centers
- o Bigger phone number fields (multiple numbers)
- o FAX #
- o Discussion of upper vs mixed case for org and net names.
- [there is a practical limitation of the pilot db, in that it
- will not fold case for searches.]
-
- Questions were raised as to what limitations should be placed on
- the distribution of this information, if published. Following
- objections to having internal operations numbers available to
- arbitrary end-users, Ittai Hershman proposed limiting the
- distribution of the information to NOCs & NSCs, with harshly-worded
- boilerplate against indiscriminate release. A quick hack to limit
- availability is to include an access string in the finger query,
- acting as a pseudo password; Instead of ``finger
- psinet-nsc@nic.near.net'', something like ``finger
- psinet-nsc-abqothl@nic.near.net''.
- DETAILED NOTES of the 11/20 meeting (second of two) by Dan Long
- The second meeting focussed on mechanisms for handoffs of tickets
- between NSC's. We agreed that a similar format to that described
- above should be used to allow handoffs to be generated and parsed
- either manually or automatically.
- The group brainstormed a list of fields that would be of interest:
-
- o Description of problem
- o Description of solution
- o Location (or Source/Destination) of problem: AS#, Net#, Host
- Address, Service Description, etc.
- o Problem Start/End Date/Time
- o Ticket Open/Close Date/Time
- o Ticket Number (made unique by prepending a unique NSC
- identifier)
- o NSC List (list of NSCs that have handled this problem)
- o Notifications (who should be kept informed about this problem?)
- o Contact Info (who should be worked with to resolve this
- problem?)
- o Notes: number, date/time, author, text
- The group agreed that this list of items will likely need to evolve
- but that we should be conservative in the addition of fields so
- that the syntax remains simple and that the burden on human
- operators is minimized.
- There was a fair amount of discussion about notifications and
- whether end-users should be notified about steps taken by NSCs
- other than the originating NSC. Organizations have different
-
-
- 4
-
-
-
-
-
- policies about how much detail to reveal. The consensus was that
- the originating NSC can use the Notifications field to include the
- user (or not) as they see fit and that other NSCs working on the
- problem should honor the notifications field to report progress.
- In the original paper by Matt Mathis, the idea was for the entire
- ticket to be handed off to the appropriate NSC and for the new NSC
- to deal with the user. We agreed on a change whereby the
- originating NSC maintains the contact with the user and keeps its
- own ticket open on the problem. It may, as the document describes,
- hand the problem off to another NSC but that NSC must then report
- back when it is done to the originating NSC who, in turn, will
- obtain closure with the user. The handoff will be handled much as
- the original document describes.
- The general format of the mail message will be:
-
-
- To: trouble-ticket-handoff@destination (the specific address for any given
- NSC is in the NSC PhoneBook)
- Subject: ticket-number {handoff, update, close} note-number
- (note-number is 0 on 1st handoff,
- 1 on 1st note,
- ...
- N+1 on close)
- And in the body of the message:
- Fieldname: (contents)
- ...
- ...
- Note: 1 Date Time Author
- (note text)
- ...
- ...
-
-
-
- Several people volunteered to begin using these formats for status
- updates and ticket handoffs. Dan Long to publish detailed writeup
- of formats so people can get started.
