- Minutes
- November 20, 1991
- Santa Fe, New Mexico
-
- Chair:
- Sue Hares/Merit (skh@merit.edu)
-

- Minutes:
- These minutes cover the Wednesday evening session held from
- 6-7 P.M.

- +-----------+
- | Objective |
- +-----------+
-
- The objective of the session was to begin work on identifying what
- tools are needed and available for assisting in the deployment and
- management of OSI protocols in the Internet. Five tools were dis-
- cussed. Sue and Cathy Wittbrott (ESNET) will produce an Internet
- Draft (I-D) expanding on the information below. The intent is to end up
- with an Internet Standard for ad-hoc OSI tools. The I-D will specify
- the required and recommended tools. However, the listing of tool
- implementations will be in the NOC Tools Catalogue.
-
-
- +----------+
- | OSI Ping |
- +----------+
-
- Ping is critical and is already supported on most intermediate systems
- (ISs). All known implementations use the method adopted by ISO (i.e.,
- the new PDU type) except for Sun, which implemented the selector-based
- ping. The ISO method is the one to be mandated and by the I-D in all ISs.
-
- Most end systems (ESs) do not implement osi ping, but the I-D will
- mandate it for all ESs.
-
- Ping needs to use some name-to-address mapping, such as an '/etc/isohosts'
- table.
-
- The I-D should consider including features from IP ping other than the
- basic mechanism, such as 'fill'.
-
-
- +----------------+
- | OSI Traceroute |
- +----------------+
-
- Traceroute is also important to debugging network problems.
- Traceroute is not widely available on popular platforms. We need at
- least some simple functions first, then features like source route
- later. Traceroute should also use the '/etc/isohosts' file for
- name-to-address mapping.
-
-
-
- +--------------+
- | Ping Monitor |
- +--------------+
-
- This is a useful tool, but not as important as the other tools. It
- will be suggested, but not mandated.
-
-
-
- +----------------------+
- | Routing Table Dumper |
- +----------------------+
-
- Both ESs and ISs should have a capability to locally dump the routing
- tables (the moral equivalent of 'netstat -rn'). We should specify in
- the I-D what information is useful to see. Note that the information
- should be consistent with the MIBs.
-
-
- +----------------+
- | Transport Ping |
- +----------------+
-
- In addition to verifying that the network entity is alive via ping,
- there was some feeling that it would be useful to have a transport
- ping as well. Currently, FTAM is used to verify layer 4+
- connectivity, but this relies on getting all selectors right. Due to
- lack of familiarity with OSI and its terminology, selectors and other
- higher-layer configuration information is not always understood and
- correctly configured. A transport ping to a well-known transport
- selector might be useful. This tool needs more thought and will not
- be included in the I-D.
