- | Introductions |
- +---------------+
-
- The first meeting of the Network OSI Operational (NOOP) Working Group
- was opened by the Chair, Sue Hares (Merit). A minute-taker was
- selected, introductions were made, and the agenda was presented and
- approved as presented.
-
-
- +---------+
- | Charter |
- +---------+
-
- Sue presented the NOOP WG proposed charter for discussion. It was
- agreed that an additional category be added to the areas for
- publication, that of tutorials on OSI relevant to the WG's
- activities. Several of these were identified immediately:
-
- * DIS 10589 - Ross Callon (DEC) agreed to find or write a
- tutorial on DIS 10589, the IS-IS Intra-domain Routing
- protocol;
-
- * IDRP - Dave Katz (Merit) will write a tutorial on the
- Inter-domain Routing Protocol, currently under
- consideration in ANSI and ISO; and,
-
- * CLNP and ES-IS - Rob Hagens (U. Wisc) will allow us
- to post two tutorial articles he's written, and
- previously published in Connexions on CLNP and ES-IS.

- | Routing Plans |

-
- Tutorial on OSI NSAP Guidelines
- -------------------------------
-
- As an introduction to the discussion of routing plans, Ross presented
- a tutorial on the Internet Draft document, "Guidelines for OSI NSAP
- Allocation in the Internet" (Colella, Gardner, Callon). The slides
- will be included in the proceedings.
-
-
- Five Questions about NSAPs
- --------------------------
-
- Sue addressed the five most-often asked questions about NSAPs:
-
- 1) How does one get NSAPs outside the US?
-
- The authority for NSAP allocation under the Data Country
- Code (DCC) is assigned by ISO to the ISO Member Body (MB)
- from each country. In the US, for example, this is ANSI;
- in the UK it is the British Standards Institute. Each MB
- is responsible for administering (or delegating the adminis-
- tration of) NSAPs under its DCC.
-
- Alternatively, one could approach an organization that has
- obtained an International Code Designator (ICD), which are
- not country-based.
-
- 2) What happens when you change regionals?
-
- If your NSAP addresses are taken from a regional's address
- space and you change regionals, your addresses will need
- to change. This is a consequence of using hierarchical
- addressing.
-
- Auto-configuration of ES NSAPs will help this, but there is
- not standard on this to date (but see below).
-
- X.500 must be capable of supporting this transition. Since
- the primary source of addressing information for communicants
- will be acquired through X.500, X.500 must have mechanisms
- to support wholesale changes of NSAPs.
-
- 3) What is the state of auto-configuration of NSAPs?
-
- Today, some vendors use the ES-IS HELLO PDU to construct ES
- NSAPs. The ES listens for a HELLO when it is booted, and
- uses the area address of the IS for its area address. The
- ES uses its own IEEE MAC address in the system ID field of
- the NSAP.
-
- There is a new work item in ANSI X3S3.3 for support of address
- transition. The proposed mechanism is to use IS-IS flooding
- and ES-IS to distribute new NSAP information within and area.
- Note that this does not obviate the need for some support from
- X.500 as discussed in the previous question.
-
- 4) Quality of Service (QoS) -- what about it?
-
- QoS is also known by other names, such as Type of Service (ToS)
- and policy. This is considered a research issue (and is for
- further study by someone else).
-
- 5) How does a company transition between two different
- OSI NSAPs?
-
-
- It was decide this question was simply way of
- asking question 2.
-
-
- Sample Routing Plans
- --------------------
-
- There was general agreement on several points:
-
- * Regionals and Backbones should each obtain an AA from GSA or
- an ORG ID from ANSI and allocate addresses to their clients
- based on these (Richard agreed to distribute information on
- how to obtain an AA to the WG mailing list).
-
- * Multiply-homed clients (e.g., campuses) should use addresses
- taken from the address of their primary point of attachment.
-
- * For administrative reasons, a regional *could* further subdivide
- the RD field. For example, MIDNET clients are organized along
- state boundaries. The first nibble of the RD field could be
- used as a state identifier, with the other 12 bits managed by
- the state. It was decided that this is not a good idea:
-
- - each additional subdivision wastes address space, so this
- should only be done when absolutely necessary,
-
- - does not provide a significant added value to the state
- (new RDs are not needed that often),
-
- - it may cause confusion because current administrative fields
- in the NSAP DSP (i.e., AA, RD, and Area) are being used
- synonymously with topological routing structures, and these
- bits are *not*, and,
-
- - it's really just as easy for the regional to manage a flat
- RD space.
-
- Seven people agreed to write routing plans and submit them for
- distribution to the WG. These plans can be used as the basis for
- discussion of issues that arise and as examples for others who are
- contemplating developing NSAP addressing and routing plans. No
- specific dates were set, but the following lists those who agreed to
- contribute a plan:
-
- * CICNET -- Linda Winkler (Argonne National Lab)
- * ESNET -- Tony Hain (Lawrence Livermore National Lab)
- * MIDNET -- Dale Finkelson (MIDNET)
- * Mitre -- Walt Lazear (Mitre)
- * NSFNET -- Dave Katz (Merit)
- * OARNET -- Kannan Varadhan (Ohio Academic Resource Network)
- * Westnet -- Carol Ward (University of Colorado)

- | Tools |
- +-------+
-
- As in the operational IP networks, there is a need for OSI tools
- to support network operation and debugging. Sue broke this up
- into a number of separate areas.
-
-
- Utilities
- ---------
-
- Various OSI-based utilities are needed. Some are available and
- some are not. These need to be identified and implemented. The
- slides identified a number of utilities. Note that network
- management is not of immediate concern to the WG, but CMIP-based
- NM is anticipated.
-
- [Editor's note: The text of the slides will be sent to the mail group.
- The basic utilities needed were:
- - ISO versions of ping (ISO echo RFC 1139),
- - ISO version of traceroute (using ISO ping as packet sent)
- - method to display ISO routes
- - method to display ES-IS cache ]
-
-
-
-
- Making NM Monitors
- ------------------
-
- Utilities such as ISO ping can be combined to create Network Management
- Monitors. Sue Hares will send a write up of a simple network management
- monitor to the mailing list.
-
-
- NOC Tools 2
- -----------
-
- This working group will collect information on OSI tools.
- A document point to OSI utilities in either the NOC tools RFC will
- be written. Please send information about OSI utilties to
- noop@merit.edu.
-
-
- Router and Host Survey Documents
- --------------------------------
-
- It would be useful to have a pair of documents that survey OSI
- software availability, one each for hosts and routers. Emphasis
- is on those tools that are needed to run an operational network.
- Everyone is asked to contribute material to this effort. Again
- send information to noop@merit.edu.
