- 2 JUSTIFICATION OF PROPOSED STANDARD
-
-
-
- 2.1 Needs
-
-
- The need for an American National Standard for ICMP is based on the
- widespread market penetration and growing commercial importance of
- computer systems that use the TCP/IP suite of internet protocols
- for host-to-host communication. Users and vendors would benefit
- greatly from a consolidated specification of ICMP, drawn from the
- existing Internet Request for Comments (RFC) documentation, which
- could be used to evaluate the conformance of products that imple-
- ment it and to place ICMP in a formal context in which its rela-
- tionship to other standard protocols may be clearly established.
-
-
- 2.2 Recommended Scope of Standard
-
-
- The proposed standard will specify ICMP as it is currently under-
- stood within the Internet engineering community. The scope of the
- proposed standards development project does not include the speci-
- fication of any function or feature that has not been accepted
- within the community that is currently implementing, deploying, and
- using ICMP.
-
-
- 2.3 Existing Practice in Area of Proposed Standard
-
-
- The proposed standard will formalize accepted existing practice,
- based on existing documentation, in which ICMP is used in conjunc-
- tion with the Internet Protocol (IP).
-
-
- 2.4 Expected Stability of Proposed Standard
-
-
- The architecture of the TCP/IP protocol suite, with which ICMP is
- closely associated, is well understood and stable. New architec-
- tures for end-to-end communications are likely to generate entirely
- new sets of standards, rather than destabilize the standard for
- ICMP.

- 3 DESCRIPTION OF PROPOSED PROJECT
-
-
-
- 3.1 Type of Document
-
-
- The proposed development project will produce an American National
- Standard for Internet Control Message Protocol.
-
-
- 3.2 Definitions of Concepts and Special Terms
-
-
-
-
- 3.3 Expected Relationship with Approved X3 Reference Models
-
-
- The proposed standard will define a protocol that supports func-
- tions and capabilities associated with the Network layer of the
- Open Systems Interconnection Reference Model (ISO 7498)
- architecture. It will not, however, define an "OSI Network Layer
- Protocol".
-
-
- 3.4 Recommended Program of Work
-
-
- The program of work will consist of the preparation, from existing
- documentation concerning ICMP, of a document that captures all of
- the currently accepted ICMP practice, in a form that is as close to
- the existing internet documentation as the rules for the presenta-
- tion of American National Standards permit.
-
-
- 3.5 Resources
-
-
- The resources of Task Group X3S3.3, Network and Transport Layers,
- are expected to be available to carry out the program of work.
- X3S3.3 has 26 voting members, representing a broad spectrum of
- users and suppliers of computer and communications equipment and
- services. The resources of the Internet Activities Board, which
- administers the internet standards that apply to the operation of
- the internet, and of the Internet Engineering Task Force, which is
- responsible for the technical specification of ICMP (and the other
- internet protocols), are also expected to be available.
-

-
-
-
- 3.6 Recommended X3 Development Technical Committee
-
-
- It is recommended that the proposed project, if approved, be
- assigned to Task Group X3S3.3, Network and Transport Layers, of X3
- Technical Committee X3S3, Data Communications. The proposed
- project is closely related, both technically and administratively,
- to project 365, which has previously been assigned to X3S3.3.
-
-
- 3.7 Anticipated Frequency and Duration of Meetings
-
-
- If the proposed project is pursued by task group X3S3.3, as recom-
- mended above, it is anticipated that the equivalent of one hour
- during each of the task group's 6 five-day meetings each year will
- be devoted to work on the project.
-
-
- 3.8 Target Date for dpANS to X3
-
-
- A draft proposal for an American National Standard Transmission
- Control Protocol could be conveyed to X3 by October 1, 1990.
-
-
- 3.9 Estimated Useful Life of Standard
-
-
- The useful life of the proposed standard coincides with the useful
- life of the set of internet standards that comprise the "TCP/IP
- protocol suite". This lifetime is expected to be very long,
- spanning at least several decades.
-
-
-
- 4 IMPLEMENTATION IMPACTS
-
-
-
- 4.1 Impact on Existing User Practices and Investments
-
-
- The proposed standard will formalize existing user practice in the
- area without modification. The impact of the proposed standard
- will therefore be limited to the salutary regularization of the
- documentation and points of reference for ICMP.
-
-

-
-
-
- 4.2 Impact on Supplier Products and Support
-
-
- As above; with the additional benefit that suppliers of products
- that implement or use ICMP will be able to focus their evaluation
- of ICMP standard compliance requirements on a single reference
- point.
-
-
- 4.3 Techniques and Costs for Compliance Verification
-
-
- Verification of compliance with the proposed standard will be
- performed in conjunction with verification of compliance with the
- associated Internet Protocol. The contribution of ICMP testing to
- the total cost of Internet Protocol conformance testing is expected
- to be very small, on the order of 1%.
-
-
- 4.4 Legal Considerations
-
-
- No special legal issues are raised by the proposed project, which
- covers material that is non-proprietary and freely distributed.
-
-
-
- 5 CLOSELY RELATED STANDARDS ACTIVITIES
-
-
-
- 5.1 Existing Standards
-
-
- The proposed project will formalize the existing internet standard
- for ICMP, for which the basic references are RFCs 792 and 1122.
-
-
- 5.2 X3 Standards Development Projects
-
-
- The proposed project is closely related to the work on the OSI
- Internetwork Protocol under X3 project 365.
-
-
- 5.3 X3/SPARC Study Groups
-
-
- The proposed project has no relationship to any existing X3/SPARC
- Study Group.
-
-

-
-
-
- 5.4 Other Related Domestic Standards Efforts
-
-
- The internet standards effort pursued by the Internet Engineering
- Task Force and its parent organization, the Internet Activities
- Board, is and will continue to be the source of technical input to
- the process of developing an American National Standard for ICMP.
-
-
- 5.5 ISO Standards Development Projects
-
-
- There is no related ISO standards development project, and it is
- not anticipated that the proposed project will result in the
- initiation of any new work in ISO.
-
-
- 5.6 Other Related International Standards Development Projects
-
-
- As above.
-
-
- 5.7 Recommendations for Coordinating Liaison
-
-
- None.
-
-
- 5.8 Recommendations for Close Liaison
-
-
- Close liaison, in the form of joint development work and/or joint
- meetings, with the Internet Activities Board and the Internet
- Engineering Task Force (and/or its appropriate working groups) will
- be essential.
