Proposal for a CLNS routing domain object for the RIPE database.
by Henk Steenman 21 Jan '94

21 Jan '94

Here is the proposal for the CLNS routing domain object for the RIPE datase as will be presented next tuesday during the DB workgroup meeting. This version is almost similar as the one presented at a previous RIPE meeting. The main differences are a new attribute "dom-name", an introduction describing shortly why such an object is desired and an appendix that gives a very short comment on the breakdown of NSAP's for some commonly used AFI's. - Henk Steenman SARA, NIC --------------------- CUT HERE --------------------------------------------- CLNS routing-domain object for the RIPE database Version 1.2 Jan 1994 Henk Steenman Henk_Steenman(a)sara.nl +31 20 5928038 CLNS routing-domain object Page 2 Introduction. ____________ In the RARE lower layer technology work group for CLNS it was recognised that in order to coordinate routing between CLNS routing domains a central registry for such domains was necessary. At a meeting of the work group at the 27 IETF in Amsterdam it was decided to write a registry specification. At this meeting the RIPE NCC offered to extend their database for IP domains/networks with CLNS related objects if a sound proposal came forward. Below a description of a database object for CLNS routing domains is defined. The object can be used to describe some general information of a CLNS routing domain such as NSAP prefix, name, description and responsible persons. It can also be used to describe routing policies in a manner comparable to that for IP domains ( AS's ) as defined in the paper RIPE 81 [1]. The attributes describing routing policy are intended to be set-up such that routing tables for static inter-domain routing can be derived from them or excisting routing can be checked against the described policy. It is desired that tools are made to serve these tasks. It is understood that the object as described below is subject to change when CLNS routing developes. An example of this could be the future availability of IDRP for dynamic inter-domain routing. In an appendix, some generally used combinations of the Authority and Format Identifier (AFI) and the Initial Domain Identifier (IDI) are shown. CLNS routing-domain object Page 3 Object Description _________________ dom-prefix: Defines an unique routing domain, characterised by a NSAP prefix , within a certain prefix hierarchy. Example: dom-prefix: 39528f1100 dom-name: String representing the routing domain. Format: Text string. Example: dom-name: SURFnet-CLNS descr: Description of the organisation and place of its location Format is equal to the descr attribute as defined for IP autonomous systems in [1]. bis: Format : < bis NET > < dom-prefix > NET of boundary intermediate system to between two domains Example: SURFnet BIS for EuropaNet bis: 39528f1100100020000000000100000c0429b400 39528f1103 CLNS routing-domain object Page 4 dom-in: Description of accepted routing domain prefixes, from other domain BIS. Analogue to "as-in" in [1]. Format:< dom-prefix > < cost> <routing policy expression > For every BIS you peer with, there should be such an entry <dom-prefix> is the routing domain prefix where the BIS you peer with belongs to. <cost> is a relative cost to discriminate between different routes to the same domain. The lowest cost gives the most preferred route. <routing policy expression > can be expressed in the following way's 1: list of "dom-prefixes" Example: dom-in: 39528f1103 100 39124F 470005 2: KEYWORD Only one keyword for the moment ANY - accept everything you get announced. 3: A logical expression of 1 and/or 2. The following operators should be defined AND OR NOT Parenthesis are used to group rules. Example: dom-in: 39528f1103 ANY AND NOT 39756f Accept all announcements from EMPB BIS except for the Switzerland routing domain. CLNS routing-domain object Page 5 dom-out: Routing domain prefixes announced to other BIS'. Analogue to the "as-out' tag in [1]. Format : < dom-prefix > <routing policy expression > <dom-prefix> is the routing domain prefix where the BIS you peer with belongs to. <routing policy expression > As defined with the dom-in tag. Example: dom-out: 39528f1103 39528f1100 AND NOT 39528f1100000910 Advertise to Europanet the SURFnet-CLNS routing domain but not the PTT-Research routing domain. default: Indication how default routing is done default: < dom-prefix> <cost> <dom-prefix> again is the prefix of the domain where the BIS peer is in. <cost> indicates which default path is preferred. In a static routing environment this doesn't make sense. Example: default: 39528f1103 10 Default everything is routed to 39528f1103 CLNS routing-domain object Page 6 admin-c: Administrative contact. Format equal to admin-c in [1]. tech-c: Technical contact Format equal to tech-c in [1]. guardian: e-mail and/or postal address of domain guardian. Analogue to AS guardian in [1]. source: Source of the information. Equal to source field in [1]. remark: remarks or comments Equal to remark field in [1] changed: Who and when of last change. Equal to change field in [1]. CLNS routing-domain object Page 7 Example: _________ dom-prefix: 39528f1100 descr: SURFnet-CLNS domain. bis: 39528f1100100020000000000100000c0429b400 39528f1103 dom-in: 39528f1103 100 ANY AND NOT 39528f1100000910 dom-in: 39528f1100000910 100 39528f1100000910 dom-out: 39528f1103 39528f1100 AND NOT 39528f1100000910 dom-out: 39528f1100000910 39528f1100 default: 39528f1103 10 admin-c: Victor Reijs tech-c: Henk Steenman guardian: domain-guardian(a)surfnet.nl source: RIPE changed: henk(a)sara.nl 930716 SURFnet accepts from EMPB ( 39528f1103 ) all prefixes but one, 39528f1100000910, which is PTT-research that is connected to both EMPB and SURFnet. From PTT-research SURFnet only accepts the PTT-research prefix. SURFnet announces to EMPB, 39528f1100 but not 39528f1100000910. To PTT-research only 39528f1100 is announced. Translated to static routing; on the SURFnet BIS connected to PTT- research, there is a static route to 39528f1100000910. And on the SURFnet BIS connected to EMPB there is a static route to all other know prefixes. On both the PTT-reserach and EMPB BIS's connected to SURFnet there is a static route to 39528f1100. ^L ^L CLNS routing-domain object Page 8 Appendix A. ___________ Definition of NSAP structure is defined in OSI 8348 Ad2 [2]. In general: NSAP's are always an integer number of octets where the AFI is always one octet and the IDI is always an integer number of octets. NSAP's are hierarchical structured and once the AFI is decided upon, structuring of the rest of the NSAP is up to authorities down the tree. Two common AFI are 47 and 39 and can be described by some general rules. AFI: 39 Describes that the following two octets are the ISO DCC country codes. Since these codes are always described by three digits, padding with an "f" is necessary to complete the 2 octets. Further structure is done by the authority for each country and there is no general rule. AFI: 47 IDI: 4 defines OSINET. Followed by a two byte organisation identifier. IDI: 5 defines US-GOSIP Version 1 defines a two byte organisation identifier. Version 2 defines a one byte data format identifier, a two byte zero field a three byte administrative authority a two byte routing domain id. ^L ^L CLNS routing-domain object Page 9 References __________ [1] : RIPE-81, Representation of IP routing Policies in the RIPE database, Tony Bates, Jean-Michel Jouanigot, Daniel Karrenberg, Peter Lothberg and Marten Terpstra, Feb. 1993 [2] : Network Services Definition, Addendum 2, covering Network Layer Addressing.

Latest on the dbase software
by Marten Terpstra 13 Jan '94

13 Jan '94

Folks, here is an update of what has happened with the database software over the last few months: - options have been added to whoisd (some you may have already seen): -r do NOT lookup referenced objects -F do fast lookup, in short format, without reformatting (implies -r) -V faciltates version numbers to be logged in queries this is used to identify prtraceroute and prcheck queries. For instance, prtraceroute is logged with -Vpt0.32 at the moment, where "pt" stands for prtraceroute and 0.32 is the version of prtraceroute used. This option is internal to special tools that use the database, and should NOT be used on command line. -k keepalive. This option will keep the connection between client and server open after a query. Also this option is ONLY used in tools that need a number of queries fast after one another (like prtraceroute) All the options (except the -V and -k) are available in the latest ripe whois client: ftp.ripe.net:tools/ripe-whois.tar.Z Please note that these options will NOT work with other whois servers, and only work with the latest beta whoisd. - the "notify" attribute as defined in ripe-096 has been implemented. The database has accepted "notify" and "maintainer" already for some months, but now the functionality of "notify" has been added last week. The functionality of "maintainer" is not implemented yet. You are welcome to use "notify" but please do not go mad on it. - the guarded stuff has (finally) been implemented, and is currently under heavy test at the NCC. It includes all the things needed to implement ripe-81 guarded attributes, including conflict handling and all other things needed. A document describing the procedures is being written (at this moment actually) and will be ready soon. - many many many small and big bugs have been reported and fixed. Most modules of the software have had some 5-10 fixes each, and the main programs like whoisd have had some 20 fixes. Many of these bugs were nasty little programming errors that appear in only some circumstances, and were thus hard to find. Also, many things have changed to speed things up a bit more. - the software is unfortunately still beta, simply because there are too many changes made every day. Once the guarded attributes have been debugged and the documentation written ;-( it will be an official release. - Some stats, taken out of the quarterly report December 93 (which will be published this week): (All stats over Oct, Nov and Dec 1993) queries: 177,423 e-mail messages with updates processed: 3,575 number of objects processed from these e-mails: 42,767 number of networks in database: 29,646 number of persons in database: 13,238 number of domains in database: 2,339 number of AS in the database: 224 More info of course at the RIPE meeting. If you have any questions about the database (from general to very specific) please send me a mail. See you in 11 days. -Marten

NIC Handles
by Daniel Karrenberg 21 Dec '93

21 Dec '93

Friends, after all the useful input from you and some more thought we have concluded that introducing the RIPE handles this year is too ambitious. So it will be January. I see two alternatives: 1) We wait until the RIPE meeting in order to discuss all the possibilities and make a firm decision. This delays introduction well into February. Database exchange with the InterNIC is also delayed until then. 2) We introduce like planned in the first week(s) of January. In order to address concerns quick and easy assignment we will operate a server for real-time assignments. If this does not solve the expected problems we can decide about local assignements at the RIPE meeting. In order not to delay database exchange with the NIC we favour option 2. About the real-time server: It will run on a special TCP port accessible only to local IRs. The server will accept a person object with "nic-hdl: assign" and immediately echo back the person object with the NIC handle or an error message. We will provide a filter "assignhandle" to go with it so you can integrate it into your own software (we will often run it in vi/emacs). We will also provide the filter mentioned in the paper which adds handles to an existing database without handles. Does anyone have real problems with option 2? Daniel

I agree with your point of view, that we should thrive to have only _very_ few instances that assign handles! Everything else is calling for trouble. >The problem of delay in registrations by "regional" >registries could perhaps be overcome by an automated >"handle assignment" service by RIPE, where a handle >could be obtained interactively by authorised persons. Given the turnaround-time with the new DB-software, I really don't see where there is potential for delay in registering objects? But maybe we could (on paper) relax the rules a bit to officially allow the registration of person objects that are not (yet) referenced by other objects. The software never prohibited this, as much as I know. Maybe this is the time to think about combining the idea of an interactive handle generator and an interactive (eg. prompt-mode) (person-)object registration script, offered on a special telnet port at the NCC?

(ie. I can get my person object registered in any database other than the RIPE-DB with my RIPE-assigned Internet Handle) **correct?? - we have to get this going by a) converting all existing handles, which have by definition been assigned by the InterNIC into the -INIC format/syntax b) assign -RIPE format/syntax handles for all the others in the RIPE-DB - to keep it going we refuse person objects, that do neither come with an Internet Handle, nor request assignment by the agreed string of "assign" Anything wrong with this?

RIPE Handle document
by Marten Terpstra 07 Dec '93

07 Dec '93

Folks, Please find below the draft document to implement RIPE handles in the RIPE database. Please read it carefully, since it will impact registration of people. Current timescales: from draft to official document: Dec 13th (1 week from now) implementation: Dec 20th (2 weeks from now) Comments please. -Marten Internet Handles and the RIPE Database Daniel Karrenberg Marten Terpstra Document ID: ripe-nh ABSTRACT This document describes the need for unique iden- tifiers for Persons and the way they are assigned and used in the RIPE database. Why Internet Handles Like other registry databases the RIPE Network Management Database [ripe-013] stores information about contact persons for various other object types stored in the database such as network numbers, DNS domains and autonomous systems. Data about each contact person is stored in a "person" object which in turn is referenced by the other objects. This way data about a real person is stored only in one place, the person object. This has the advantage that any necessary changes need to be done only in one place rather than in each object the person is a contact for. Originally each person was uniquely identified by their full name and references were implemented by storing the full person name in the contact attributes of other objects. A side effect of this was that the database could not store more than one person with the same full name. When this ("John Smith") problem became an issue another attribute was needed to disambiguate persons with the same name. Since the InterNIC was already using a "NIC Handle" scheme and it was hoped to unify the registry databases quickly these handles were used. NIC handles are unique identifiers consisting of two or three aphabetic cahracters and a serial number. A "nic-hdl" attribute was added to the person object. If present this "nic-hdl" is now used together with the "person" attribute to uniquely identify a person. The value of nic-hdl is a search key for the database and can be used to reference a contact person in the contact attributes of other objects. A side effect of this is that all persons needing a handle to ripe-nh.txt - 2 - disambiguate them from another person need to be in the InterNIC database in order to obtain a NIC handle. This was not considered a problem because quick unification of the databases was expected quickly. As it turns out the assignment of globally unique handles from a single number space is not likely to be feasible. Therefore there is a need for more local assignment of unique handles. These handles will also be used in the database exchange between regional regis- tries. The regional registries agreed to create separate handle spaces by appending a suffix identifying the registry to handles creating a unique Internet handle. This document describes the procedures to implement this in the European Regional Internet Registry. RIPE Handle Internet handles issued by the RIPE NCC are called RIPE handles. The purpose of a RIPE handle is to uniquely identify a person in the RIPE network management database and other related databases that choose to use it. A RIPE handle is a string of 2-3 letters immediately followed by a serial number without leading 0s followd by the string "-RIPE". Legal RIPE handles are: AB1-RIPE AXA123-RIPE XYZ99-RIPE Normally the letters are chosen to be the initials of the person. The -RIPE suffix is used to disctinguish RIPE-handles from Internet handles issued by other registries. Internet handles issued by the InterNIC in the RIPE database will be suffixed by the string "-INIC" to distinguish them from other handles. All persons in the RIPE database must have an Internet handle. Every person in any of the databases keeping contact information should only use Internet handle. Assignment RIPE handles are assigned by sending a person object to the normal update address <auto-dbm(a)ripe.net> with "nic-hdl" value of "assign". The update process will then generate a unique handle, insert the person object with the new handle in the database and report back the handle. In case there already are persons with the same full name in the database the update process will include them in the ripe-nh.txt - 3 - report so that the user can check whether he inadvertently created a duplicate person object. Users wishing to obtain a specific RIPE handle (vanity handle) can request that by specifying it after the "assign" string, e.g. "assign JB007-RIPE". If the handle in question is available it will be assigned. It should be noted that the RIPE NCC only issues RIPE handles and not other Internet handles. Usage The primary use of RIPE handles is to reference a specific person in the RIPE database, either in another object or a database query. Contact attributes can have the following types of values: John E. Doe full name not recommended AXA123-RIPE Internet Handle John E. Doe (JED12) full name (handle) recommended Wherever possible the use of full names on their own should be dis- continued. These references can become ambiguous unnoticedly at any time by another person with the same name being registered. The handle plus full name syntax is recommended because it makes it possible to detect typing errors in handles. Handles can also be used when querying the RIPE whois server. Matches will occur for either the full handle (AXA123-RIPE) or just the part before the suffix (AXA123). In the latter case all persons in the queried databases with a handle starting in AXA123 will match. Transition For the database exchange with the InterNIC it is neccessary for each person in the RIPE database to have a unique Internet handle. Therefore the NCC will assign a RIPE handle to each person without a NIC handle in the database on the 20th of December 1993. >From that point this handle must be included in any updates made to that person entry. The handle should be used in all references to a person in other database object. For the conversion of local databases the RIPE NCC will provide local registries and other interested parties with a tool which adds ripe-nh.txt - 4 - RIPE handles to persons in database objects. The tool will accept RIPE database formatted input files without syntax checking and will output the file unchanged but with handles added. The tool queries the RIPE database and can thus be run only after handles have been added to the RIPE database. Becuause there is no syntax checking the tool should work for databases with local attributes or objects as long as they adhere to the general RIPE database format. ripe-nh.txt

NIC Handles
by Daniel Karrenberg 02 Dec '93

02 Dec '93

This is the NCC's current thinking aout NIC handles. This is a quick dump, so If you have questions, please ask. Please comment! Daniel As decided at the last meeting we need to introduce unique handles in order to deal with ambiguities in the RIPE database. Especially accidental overwriting of persons will be a problem in the future with more than 10000 persons in the database now. After some discussion with the InterNIC we have concluded that a worldwide handle space is not realistic. In fact Australia has already started with their own space. Therefore we propose to start issuing RIPE handles as soon as technically feasible. Person handles will then be of the form XYZ123-INIC ABC457-RIPE .... Each physical person will eventually have one such handle only in order to facilitate database exchanges between NICs and database maintenance. RIPE handles will be assigned by sending in a person entry to auto-dbm with somethin like nic-hdl: assign which will cause the entry to be added with a new unique handle assigned. If there are other persons with the same name their entries will be returned as a check against multiple registrations. The NCC will *not* automatically assign handles to persons without handles on a "flag day". Local registries or the persons themselvews will have to do that. The reason for that is that all conflicts would need to be resolved beforehand and all persons notified of the change. This is too cumbersone, if not impossible. The NCC will flag possible conflicts present in the database today and help resolve them by notifying everyone involved and by assigning handles to all persons involved if necessary. In the future, handles will have to be used in the contact attributes (tech-c, admin-c, zone-c) in order to maintain unambiguous references. The recommended value for the contact attributes will be to list *both* name and handle in order to guard against typos in handles. Name only and handle only will also still be allowed. It might be necessary to disallow name only at some point when the majority of persons have a handle. Daniel
