| Here is another issue of our Newsletter
where we had to select the items to be printed, among the large number
of news and activities related to our group. The New Paths of Knowledge
are really getting busy…
I am particularly happy to welcome a large number of new collaborators and visitors to our group, and I know there will be more in the coming months; I take it as a definite sign that there is really something as a Global Information Society getting built among us. I hope you can be part of it, and we can work together to make it better. Happy reading, Paul VAN BINST

Our local ATM network, developed under contracts with ASCOM and CISCO, includes an ASCOM LightRing 1250 (1.25 Gbps) with two nodes, 2 CISCO LS1010 ATM switches and 2 CISCO 7200 routers. Our test programme includes IP over ATM PVCs performance measurements and tests on the ATM layer |

| ULB-STC is editor of an ACTS guideline about IP and ATM integration. It has been produced by participants of the ACTS Chain NIG: Global Network Interoperability, and particularly by the following projects: CONVAIR, DIANA, EXPERT, MULTICUBE, PETERPAN and GINA (acting as the editor). This guideline is currently in the final review process, and should be published very soon. It has been recently presented during the ATM Developments'99 conference in Rennes (30 Mars - 1 April), the Eurescom AIMS'99 Workshop in Heidelberg (11-12 May), and the NI Chain Group meeting in Stuttgart (20-21 May). It is directed to technology strategists and covers thirteen scenarios for the integration of IP and ATM. For each of these scenarios, ten basic questions have been identified. It results that a total of one hundred and thirty key messages are included in this document. | ULB/STC has been contracted by ALCATEL to make a study related to security mechanisms within Internet-based protocols. This study addresses lower layer Internet protocols used for routing and flow establishment and maintenance (i.e. not application protocols such as SMTP, nor HTTP). It is covering existing security mechanisms which have already been developped within such protocols and identifies lacks where they exist. An overview of security problems specific to multicast applications is also part of the study. In addition to these previous topics, another team of ULB/STC has been contracted to conduct a study on Multiprotocol Label Switching (MPLS). Several MPLS specific aspects are being considered during this study: use of MPLS to support VPNs (Virtual Private Networks); QOS signalling and MPLS; routing and MPLS; and finally a comparison between MPLS and concurrent technologies |

Fondation pour l'Architecture
STC is developing a collaboration with the Brussels Region “Fondation pour l’Architecture”, first in the context of an exhibition that will take place from September 21 until December 1999, on the theme of the Office: “Le Siècle des Bureaux; 1900-2000”. A series of conferences will be co-organised, among other events. For more information, please contact + 32 2 6490259.

| The ACTSLINE project has begun in March
1998 and has now entered its second year.
ACTSLINE promotes the results of ACTS (Advanced Communications Technologies and Services programme of the EU) and interprets them to identified business sectors. Identified business sectors at the present time are: -Corporate Network Managers -Telecom Operators -Regulators -Education, High Schools -Flexible Working -CATV Industry -Learned Societies -Standards Bodies -Broadcast and On-Line Service Providers -Telecom Equipment Suppliers |
Over the coming year ACTSLINE will publish
a series of management and technical briefings, interpreting the results
of the programme for particular groups of organisations.
This project is co-operating closely with other ACTS projects, especially INFOWIN which is already assisting in the dissemination of the ACTS programme. For more information on the project and its outcomes, please see the project web site at: http://www.actsline.org

| ULB/STC continues to provide networking expertise to the ETIC secretariat.
Recently, EITIRT (European IT Industry Round Table) has started collaborating
with ETIC and in this context they share the networking infrastructure
already installed at the ETIC secretariat.
Although sharing the same physical infrastructure, EITIRT resides on a different virtual network and uses a virtually separate set of network services (WEB, FTP, e-mail,…). Meanwhile, the ETIC has started piloting video-conferencing. It is intended to use this service extensively to enhance the collaboration among ETIC and their project partners. |

SARMENT, a two years project carried out between SAIT, ULB/STC and the Brussels Region is in its full development phase. This interesting multidisciplinary project includes work on three parallel activities carried out by experts from STC and SAIT: - Web traffic characterization and statistical behavior analysis using well known public Internet traffic archives as well as the STC Web traffic statistics collected by the SunNet Manager platform. - Analytical Modelling which takes into account parameters in Access Network, Web sessions and network efficiency. - Simulation of Web traffic using NS (Network Simulator) on Linux, an IP simulation tool developed at Berkeley and widely used by the research community. The project will result in three principal studies: 1 Study of Quality of Service (QoS) in today's networks 2 Study of an IP network with Web traffic 3 Study of IP applications behavior over satellite links The Study of Quality of Service in today's networks has been already realised in December 1998. The study includes models and related standards/specifications from ISO, ITU-T, ATM Forum, IETF, TeleManagement Forum and other standardisation bodies.

| Under
a contract with Digital (now Compaq), ULB/STC has designed and developed
a full and generic X400/EDI Gateway for a large Digital customer in the
banking world. The gateway system enables the bank to exchange any
type of EDI messages with partners over an X400 messaging backbone.
It is therefore generic and powerful enough to meet all kinds of requirements
depending on the EDI applications involved. The complete system has
been finalized and delivered to the bank, which will now install it in
production.
