-
- 1. Introduction and background.
- -------------------------------
- To answer the near-term need for products implementing dial-up
- functionality for X.400, both ISOCOR and maXware have recently
- introduced off-the-shelf products supporting a dial-up mode.
- In the case of ISOCOR's X.400 Lite product, a DOS-based X.400
- server can dial into centralized communications hubs and/or
- remote sites with a similar configuration. Travelling users
- on notebook computers can dial into ISOCOR's X.400 servers as
- well using async as well. Also supporting X.400 dial-up are
- Norwegian Telecom/maXware's products which include Remote User
- Agents (RUAs) for dial-up 1988 X.400 Message Store access via
- PADs.
-
-
- 2. Charter
- ----------
- The following charter was presented:
-
- APS ALLIANCE CHARTER
-
- - The APS Alliance aims to facilitate the use of X.400-based
- messaging by using dial-up connections to dramatically
- reduce costs and complexity.
-
- - The APS Alliance will:
-
- - Develop and promote a global standard for OSI
- communication over standard dial-up telephone networks
- (PSTNs), with a particular focus on X.400/X.500. Both
- client-server and server-server communications to be
- covered by the same stack.
-
- - Pursue an aggressive development schedule with the near
- term goal of delivering a specification proposal to the
- Internet community and CCITT for formalization.
-
- - Involve software developers, systems vendors and service
- providers to ensure universal acceptance.
-
-
- 3. Organization

- interim editor for the user requirement phase.
-
- An external consultant will be hired to be Editor for the
- technical specification.
-
- Members, commitments payment:
- Any company can join the Alliance as a member company. The
- members will have to pay a membership fee which will be used
- to pay an external consultant to be the editor for the
- technical specifications. David Knight will distribute a
- formal charter and a membership application form to all
- interested parties.
-
- The deadline for charter membership commitments is November
- 20th.
-

- are cooperating fully.
-
- The first important deadlines are:
- Nov 13 Deadline for comments to the preliminary user
- requirements.
- Nov 20 Deadline for written commitments from the members.
- (Members joining after this date will not be able
- to vote on the user requirements).
- Dec 1 Deadline for votes on the User Requirements.
- Dec 3-4 Workgroup meeting in London
-
-
- The procedure will be:
- Basic Spec.
- Deliver Spec.
- Build Prototype
- Start Pilot - Deliver Spec to Standards
- committee.
-
- 5. User Requirements
- --------------------
- The first draft of a user requirement document was presented.
- The second draft, updated with some comments from the audience
- is enclosed with this message.
-
- 6. Discussion
- -------------
- The following major limitations to the user requirements where
- proposed and endorsed by the audience:
-
- - The aim is to connect an application to a service (as
- opposed to connecting a computer to a network).
- Connection oriented Transport service, possibly including
- support for multiplexing (TP0 or TP2).
-
- - It was a general agreement that wireless communication is
- important, but that this consortium does not aim to solve
- problems related to wireless communication.
-
- - Several persons stated their concern that if this
- consortium should tackle security issues, the proposed time
- schedule will not hold.
-
- (A second phase of specification may be initiated when the
- work from the first phase is submitted to the standards bodies
- to work on security and wireless).
-
-
- Comments from induvidual particippants:
- - Security is best handled at the application level
- (encryption etc.. ). However, security in the form of
- authentication may be part of this project.
- - Security will be needed if the protocol supports multiple
- sessions.
- - PPP might be a model to use (Point-to-Point-Protocol for
- TCP/IP)
- - Is it possible to handle both TCP/IP and OSI Apps?
- - Managability
- - Dial-in/Dial-out
- - Dial back
- - P7 has a high overhead. We might be better served to look
- at a short stack P7.
- However if we stray from the network layer solution we do
- not have an entry into CCITT.
-
-
-
- There was a wish to establish a set of user profiles as a
- background for the user requirement work:
-
- USER PROFILES
-
- - Mobile User to corporate X.400 MS or public MS
- - On telephone line
- - Wireless
-
- - Office to Office
- - Client to Server
- - Server to Server
-
- - Smaller office to corporate hub or public MS
-
-
-
- 7. Where do we go from here
- ---------------------------
- - the formal charter + registration form + partisipant fee
- information will be sent to all interested parties.
- - the deadlines mentioned above
- (please discuss this with your end-users)
-
-
- --------------------------------------------------------------
- APS Alliance
- Suggested User Requirements
-
-
- 1. Provide means for running OSI-applications in general and
- X.400 in particular over dial-up thelephone networks.
-
- 2. The solution should be suitable for all industry standard
- operating systems and hardware platforms.
-
- 3. Support for multiple assosciations over the same physical
- connection (e.g. P7 and DAP)
-
- 4. Efficiency and simplicity (minimal overhead, high
- throughput, small amount of resource consumption, easy to
- implement, small memory demands).
-
- 5. Require minimal changes to existing implementations
-
- 6. provide support for both point-to-point connections and
- access PAD and PSDN network.
-
- 7. Must support use of any (automatic) modem and any PAD
- service.
- This means that the protocol cannot rely upon error
- correctiondone by the modem. The protocol must support use of
- both 7bit and 8bit PAD. The length of the PDU to be sent over
- the PAD must be configurable.
-
- 8. Provide reliable transfer service by including functions
- for error detection and error recovery.
-
- Added requirements since 1st version was distributed:
- -----------------------------------------------------
-
- 18. Allow for compression
-
- 19. Include placeholders for security features (which may be
- added as a "phase two".
-
- 20. The low-layer protocol should be based on some existing
- standard or implementation. (many candidates exist, ppp, z-
- modem, X.32bis etc).
-
- Technical user requirements
- ---------------------------
-
- 9. Provide a bit-transparent transfer service
-
- 10. Support use of flow control
-
- 11. Point-to-point solution should be symmetric (both parties
- may take initiative to connect)
-
- 12. No restrictions on use of particular transport service.
- (preferably provide an X.213 interface, and run higher layer
- protocols transparently.
-
- 13. Provide the ability to identify calling party (calling
- NSAP)
-
- 15. Configuration parameters should provide the ability to
- optimize throughput and reduce costs, dependent of the
- communication line.
- Error correction compression on modem should be used if the
- modems provide it.
-
- 16. Negotiation during connection establishment of possible
- options.
- (PDU size, windows size etc)
-
- 17. Optionally provide the ability to recover from telephone
- line break when using application contexts without RTSE (e.g.
- by means of TP class 4).
-
- 18. Quality of service
- - Residual error rate should be comparable to X.25
