Improved Co-ordination of ETSI, EURESCOM and ACTS Activities

A Report from the ACTS High-Speed Networking Domain Meeting

A tri-partite mapping of related work items in ETSI , EURESCOM and ACTS projects is being produced in order to improve the co-ordination among the three organisations. From the ACTS side, the mapping activity is led by the GINA project. This initiative is important for projects that want to increase their impact on developing standards, and particularly for the projects resulting from the ACTS 3rd call, which are about to start their work. ACTS projects interested in this activity can contact (email removed) , Telscom, Switzerland.

The current ATM activities in ETSI (European Telecommunications Standards Institute) and in EURESCOM (European Institute for Research and Strategic Studies in Telecommunications) were presented in the ACTS High-Speed Networking Domain meeting (Brussels, 17-18 February 1998).

ATM Activities in ETSI

Julian Pritchard, ETSI external relations officer, presented two ETSI Projects (EPs) related to ATM: EASI and BRAN. ETSI (ATM Services Interoperability) was ETSI to standardise requirements for ATM service interoperability. These requirements will be identified by the ATM Memorandum of Understanding formed by ETNO , the association of European Telecommunications Network Operators. (See " European ATM MoU Proposed by ETNO " in the ACTS NewsClips Num. 34 .) The ATM MoU intends to facilitate the large scale introduction of interoperable public ATM services. It will focus on network interoperability issues, network management functions and certain service capabilities. The internal choice of ATM technology made by each operator is outside the scope of the MoU. The phase 1 and phase 2 requirements produced by this initiative are expected June 1998 and March 1999 respectively.

EP EASI brings together manufacturers and network operators to work on the standardisation needs that may arise from the ATM MoU. In collaboration with the ATM Forum and the ITU-T , EASI will set standards for interoperable ATM networks and services that will enable industry to provide common interfaces between different network operators. EASI deliverables are expected by the end of 1998 (phase 1) and the end of 1999 (phase 2).

The ETSI Project ETSI (Broadband Radio Access Networks) was created on April 1997 to provide broadband wireless access for wire-based networks. EP BRAN will address wireless access systems with bit rates of 25 Mbit/s or more, both for business use and for residential access applications. The fixed wireless access systems are intended as high performance, quick to set up, competitive alternatives for wire-based access systems. The specifications to be developed will address the physical layer as well as the data link control layer (with medium access and logical data link control sublayers as appropriate) of broadband systems. Interworking specifications that allow broadband systems to interface to existing wired networks, notably those based on ATM and TCP/IP protocol suites, will also be developed. ETSI's current work on private and business radio networks known under the generic name of HIPERLANs (High Performance Radio Local Area Networks) will be part of the new project. To ensure overall coherence with other existing and emerging technologies, close relationships are being established with the ATM Forum , IEEE Wireless LAN Committee P 802.11, Internet Engineering Task Force , and ITU-R .

ATM Activities in EURESCOM

Image Peter Stollenmayer, project supervisor, presented the EURESCOM activities related to ATM. EURESCOM, a company founded by European PNOs to carry out pre-competitive R&D projects, has produced many results closely related to ATM technology, management, testing, and applications. Running EURESCOM projects in this area include P605 (JUPITER: Joint Usability, Performability and Interoperability Tests in Europe), P613 (Methods and Tools for B-ISDN and N-ISDN Network Integration Testing), P616 (Enhanced ATM Implementation Issues), P707 and P708 (TMN X-interface studies and experiments for SDH and ATM), and P710 (Security for the TMN X-interface). Many EURESCOM results have been used to support the European trials with interconnected ATM networks.

The most recent results of project 616, presented by Mr Stollenmayer, include:

The new project P813 (Technical Development and Support for European ATM Service Introduction) will drive the future EURESCOM work on ATM. P813 is intended to:

New ACTS Results on ATM

The two-day High-Speed Networking Domain meeting served also to present recent results from the following ACTS projects: ASICCOM , CANCAN , CASHMAN , EXPERT , GINA , THESEUS , VISEUM , and WATT .

ASICCOM presented ATLAS I, a 20 Gbit/s, single-chip ATM switch with an advanced flow control mechanism and support of different priority levels.

Two presentations addressed the issue of charging in ATM networks. CASHMAN described recent work on pricing models and accounting management. CANCAN introduced a charging model based on the concept of Poisson envelope: traffic is restricted to a Poisson stream of given mean by a filter formed by two leaky buckets with a pre-buffer. The behaviour of this filter is analysed using Markov chain animation.

VISEUM summarised the project trials on the interconnection of several museums and the access to museum image archives. Challenging aspects of VISEUM trials include handling very large images (1.6 GB per image) in various formats, a complex network topology with a trans-Atlantic link between Canada and Europe, and the use of advanced protocols such as MPOA.

EXPERT presented the status of the ATM testbed in Basel, which currently has 13 ATM switches from different manufacturers, a variety of ATM terminals and interworking units, plus traffic generation and analysis equipment. Four additional ATM switches are planned to be installed during the first quarter of 1998. Several ACTS projects use the EXPERT testbed for their trials. EXPERT already has plans to support four new projects resulting from the ACTS 3rd Call, namely DIANA, IMPACT, SUSIE and VIKING (see below). A separate presentation by EXPERT gave an overview of the VB5 standard interface between the Access Network and a Service Node in the (broadband) core network. ETSI is leading the standardization of VB5.1, a first version of the VB5 interface that supports provisioned connections in the access network. VB5.2, a superset of VB5.1 supporting on-demand connections, will be the main topic of the project VIKING.

Third-Call Projects: ATM-Internet Integration

The new projects in the High Speed Networking Domain will address different aspects involved in the integration of IP and ATM. These projects are:
AROMA Advanced Resource Management in Service Integrated Multi-layered HFC Access Networks
COIAS Convergence of Internet and ATM in Satellite
DIANA Demonstration of IP & ATM Networking Applications
ELISA European Experiment on the Linkage between Integrated Services & ATM
GINAPLUS Guidelines for Interoperability in Networks - Supplement on Satellites & Internet
IACI Internet ATM Experiments for Convergence & Integration
ITUNET International Trials with Users & Networks from European Testbeds
PETERPAN Provision of an Enhanced Transport by Exploiting Reservation in IP & ATM Networks
SUSIE Charging for Premium IP services in Information Infrastructures & Services Pilots
VIKING VB52 Interface: Key Issue in Networks for Global Deployment, Implementation & Tests
For more information see the ACTS NewsClips No. 39 and the ACTS InfoWin Bulletin 7: ACTS 3rd Call results .

The High-Speed Networking Domain meeting was followed by an Information Day on Broadband Services for ACTS Projects, where several network operators presented their plans for trans-European broadband services. See other articles in this ACTS NewsClips issue.
