- N-1-3-012.43, "Spain: a RedIRIS Update", by Jose Barbera*,
- <jose.barbera@rediris.es>
-
-
- Currently, the number of RedIRIS user organizations has grown up to
- 108, with most of them belonging to the Higher Education and Public
- Research sector from various sizes and scope (see ISOC News, Vol. 1,
- No. 1, Winter 1992, p.p. 12-13).
-
- Infrastructure
- --------------
-
- Private X.25 backbone ARTIX has expanded along the first half of 1992
- up to 9 regional nodes interconnected by 64 Kbps digital links.
- Presently, 50 RedIRIS member organizations (all main universities and
- research institutes in Spain) hold at least one access link to ARTIX.
- Others use PPSDN Iberpac connections to ARTIX, or simply the PSTN
- (eventual low-traffic volume users). Traffic volume on ARTIX has
- doubled from January to June, currently reaching 20 Gbytes/month.
-
- International bandwidth is 2 x 64 Kbps. A new 64 Kbps digital link
- Madrid-Amsterdam was added in May as part of the Ebone 92
- infrastructure to supplement the former IXI (X.25) access point, which
- was used for some time to carry all traffic types. Now the IXI line
- is used for X.25-based traffic (X.400, XXX, DECNET), whereas the Ebone
- tail link is kept for IP and CLNS traffic.
-
- For transatlantic IP traffic, EASIgate (T1 CERN-Cornell) is currently
- used as the first option. Other links from Stockholm and London are
- used as back-up.
-
- Part of the RedIRIS infrastructure is also used by other networking
- organizations in Spain such as, UUES (Spanish branch of EUnet) and ESA
- Villafranca Station, which have subscribed proper agreements.
-
- Services
- --------
-
- The RedIRIS environment offers a mixture of OSI and TCP/IP based
- services, as well as DECNET (High-Energy Physics Community). NJE
- (over different network architectures: IP, DECNET, SNA,...) is also
- supported, but the actual management remains under the responsibility
- of the EARN users group.
-
- * OSI
- ---
-
- - RedIRIS mail is the most widely extended OSI service. It is mainly
- based on an X.400 global backbone system with local gateways with
- other mail systems at each user center. There is a central X.400/SMTP
- gateway as well as a format converter between domain-defined and
- standard-attribute type of addresses. UUCP, BITNET and DECNET mail is
- converted to SMTP and X.400 at specific sites.
-
- There are presently about 100 RedIRIS organizations using the X.400
- mail, 66 out of them keep their own MTA(s). The average number of
- messages/month is now about 9,000, amounting approximately to 45
- Mbytes.
-
- - X.500 Directory Service. Run as an experimental pilot in
- coordination with PARADISE Project (COSINE). There are presently 5
- DSA based on QUIPU-ISODE. The number of registered organizations is
- now 99 with more than 5,000 entries. A standard procedure to dump
- existing information at each organization has been set up to
- facilitate the inclusion of new entry data.
-
- Public software for popular X.500 user interfaces has been announced
- to RedIRIS organizations to prompt directory use by end users.
-
- * TCP/IP
- ------
-
- TCP/IP based services are mainly used to interconnect the growing
- number of LANs. RedIRIS global internet network runs over the same
- ARTIX backbone by means of tunneling over X.25.
-
- In June 1992, 40 RedIRIS member organizations reached full IP
- connectivity. Within the RedIRIS Autonomous System there are now 57
- IP connected networks (18 class B, 39 class C). More networks are in
- the process of getting IP connectivity.
-
- The last RIPE DNS Hostcount showed 148 authorized domains under ".es"
- (many of them are Spanish EUnet customers with only mail and Usenet
- News) and about 3,800 registered hosts. In practice, only 40 such
- organizations have properly set up their own DNS server.
-
- * New services
- ------------
-
- Several information services are now being implemented. File servers
- containing information about network-related features are under
- deployment. The aim is to help local managers at RedIRIS
- organizations run their own network services at each specific site.
- Anonymous FTP and an X.500 Directory are ready available for that
- purpose. Other user-friendly interfaces such as WAIS and Gopher are
- under consideration.
-
- As to information of a broader scope, RedIRIS has recently started the
- USENET News Service in cooperation with other national network
- organizations (SWITCH, DFN, ACOnet), which established early this year
- a partnership cooperation. At this stage, the RedIRIS News Service is
- operated as an initial pilot. It is expected to turn it into a stable
- service at the end of this year.
