Some major draft decisions were made in St. Louis: 1) The WG agreed on an X.400/RFC-822 address mapping scheme for the U.S. Internet community (will be described later in this Newsletter). 2) A minimum solution for X.400 routing, using a structure of I-WEPs, was adopted. 3) Documents in the Internet X.400 Documentation will be used as a mechanism to describe and ensure end-user X.400 connectivity over different underlaying network protocol suites (RFC-1006/TCP/IP - TP-0/X.25 - TP-4/CLNP) 4) An outline of a new RFC: "Requirements for Internet PRMDs," was drafted. The project team will produce the draft RFC described in 4) to be reviewed at the next IETF in Atlanta (July 29 - August 2 1991). OPERATIONAL STATUS: The draft decisions made on address mapping, routing and documentation are to be implemented by the pilot operational Internet X.400 services now comprising 4 operational PRMDs: ARC, CDC, Hughes and XNREN. The number of real X.400 users is still very low. However with the new operational PRMDs, the number is growing. The following organizations are operational and interconnected as X.400 systems. Addressing examples are given in order to show what the X.400 addresses look like. The X.400 addresses are presented both in X.400 Standard Attribute (SA) form and in RFC 822 form.

The project is operating an RFC 987 gateway (PP) between the U.S. Internet mail service and the international R&D MHS Service (X.400). This gateway is also the experimental U.S. WEP (WEP = Well known Entry Point) in the COSINE MHS Service in Europe, and it is directly connected to other WEPs in Canada, Finland, France, Norway, Spain, Switzerland and United Kingdom. X.400 traffic to the other countries in the COSINE MHS Service, is routed via the Norwegian WEP operated by the UNINETT project. France, Norway, Spain and Switzerland are routing some of their X.400 initiated traffic destined to the U.S. Internet mail domains, via our gateway as an experiment. This means that messages initiated in X.400 can be kept in the X.400 "world" all the way to the U.S. and gatewayed here, if necessary. Due to these routing experiments the monthly traffic through our WEP has increased considerably. TECHNICAL ASSISTANCE: The project is distributing the ARGO X.400 implementation to non-commercial organizations, and we are also offering assistance to organizations who are starting to use the PP X.400/RFC-987 gateway system from UCL, London. The assistance we offer is limited to operational issues, initial PP configuration, address mapping tables, etc. E-mail us if you would like such assistance. General software support should be obtained from the pp-support team in London. EXTERNAL PRESENTATIONS: The project was presented at the 2nd Joint European Networking Conference in Blois, France, May 13 - 16 1991. "X.400 in the Internet" will be presented at the INET '91 Conference in Copenhagen, Denmark, June 17 - 20 1991. VALUE ADDED SERVICES: The project team is developing a FAX gateway service between X.400 and FAX. Status so far is that a text file can be sent to a given fax number. More work has to be done to develop this into a useful service allowing end-users to use their X.400 User Agent to send a text message to a fax- subscriber in the U.S. It is a goal to negotiate agreements with other countries such that X.400 users in the U.S. also can send international fax using similar fax gateways in other countries. This service, when developed, will be made available for all X.400 users in the Internet X.400 service, and also on a bilateral basis to X.400 users in other countries. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - * * * Topic of today: * * * The "St. Louis decision" on address mapping. -------------------------------------------- The draft decision in St. Louis is valid for the U.S. Internet, and can also be viewed as a recommendation for communities outside the U.S. The address mapping issue can be split into two parts: 1) Specification of RFC-822 addresses seen from the X.400 world. 2) Specification of X.400 addresses seen from the RFC-822 world. 1) Specification of RFC-822 addresses seen from the X.400 world. The following is from the St. Louis minutes: " It was agreed that RFC822 addresses should be expressed using X.400 domain defined attributes. Furthermore, a special PRMD named "Internet" will be defined to facilitate the specification of RFC822 addresses. For example, an X.400 user will address an RFC822 recipient by constructing an X.400 address such as: /c=us/admd= /prmd=Internet/dd.RFC-822=user(a)some.place.edu/ Participating MTA's will be configured to recognize "/c=us/admd= /prmd=Internet/" as a special case. The presence of this address will cause a message to be routed to a regional RFC987 gateway. In effect, this special PRMD identifies a community of gateways to RFC822 recipients. This strategy is user friendly in that all users everywhere need only remember this one address, and it is efficient in that it avoids having to establish a single, common gateway which would tend to become a bottleneck and single point of failure." 2) Specification of X.400 addresses seen from the RFC-822 world. The following is also from the same minutes: " After considerable discussion, it was agreed that RFC822 users should be able to address X.400 recipients in RFC822/Internet terms. This implies the necessity of maintaining and distributing address mapping tables to all participating RFC987 gateways, at least in the short term. Other mapping strategies were discussed (loudly and enthusiastically), but it was shown that these alternate strategies would sometimes cause messages (or replies to messages) to pass through more than one gateway. Since this behavior would probably cause information to be lost in translation, it was quickly agreed that the alternate strategies were inferior to the good old table driven approach. Nevertheless, it was also pointed out that some X.400 addresses do not map cleanly to RFC822 addresses, even when the table driven mapping strategy is used. For example, X.400 personal names which contain generation qualifiers, personal names which contain initials but no given name, and initials which contain periods cannot be mapped to RFC822 symmetrically such that a reverse mapping is possible. Similarly, X.400 addresses which contain X.121 address elements (sometimes used for expressing fax telephone numbers), unique UA identifiers, or physical addressing attributes cannot be mapped nicely. Consequently, it will be necessary for RFC987 gateways to generate RFC987 address syntax occasionally. It was recommended that our RFC should contain guidelines for the creation of X.400 personal names. In following these guidelines, users will avoid creating personal names which can not be mapped nicely between X.400 and RFC822. It was generally agreed that long term reliance upon static mapping tables is unacceptable. Therefore, it was agreed that the X.400 Operations Working Group should devise a strategy for using X.500 directory services instead. Another option could be to use the DNS system for this purpose, if the X.500 infrastructure appears to be too premature." In other words, in most of the cases RFC-822 users will not see the difference between an RFC-822 address and an X.400 address. Example: The X.400 address: C=us; ADMD=ATTMail; PRMD=CDC; O=CPG; S=Jordan; G=Kevin will from an RFC-822 user look like: Kevin.Jordan@cpg.cdc.com The mapping tables in the gateways will describe this mapping. The other way around, an X.400 user, will normally see the difference of an X.400 address and an RFC-822 address, because the RFC-822 address will be using PRMD=Internet and dd.RFC-822 (example): The RFC-822 address: ok@subdomain.edu will from an X.400 user look like: C=us; ADMD= ; PRMD=Internet; DD.RFC-822=ok(a)subdomain.edu The decision to use Domain Defined Attributes (DDAs) requires modification of the current mapping table coordination procedures defined by the European RARE-WG1. Such modifications have already been discussed and some proposals are on the table. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Internet X.400 Project Contact Points: -------------------------------------- If you need information from the project, please look first in the catalog.txt file in our file server and check if there are some documents there that might give you the information you need.
