Introduction


1 INTRODUCTION

Purpose and Scope

The VIVALDI project is highly relevant to the individual partners’ future technology and product plans. To this end participants will produce, towards the end of the project, a "Plan for using and disseminating knowledge" indicating how the knowledge gained will be used.

The Plan will include the following parts: • Overview and description of the project and the results • Description of the exploitation intentions by each of the partners • Search for collaborative exploitation • Assessment of European interests Each partner will provide its own part in the “plan for using and disseminating knowledge" which will be updated in future revisions.

Overview of the Project


2 OVERVIEW OF THE PROJECT

2.1 Project Description

VIVALDI is a 24 Months project in which 2 leading companies in the satellite ground segment area, one S/W developing house, two service providers and two academic partners cooperate. The partners are from 7 Different countries, 3 are SME. VIVALDI will advance the state of the art of interactive broadband satellite access by optimal convergence of session-based services over the European standard DVB-RCS. VIVALDI will research and develop the architecture, technologies and protocols ensuring that the satellite segment interoperates transparently and efficiently with the end-to-end IP networks at large. It will allow a generalised and affordable availability of broadband access to European users, including those in less developed regions, peripheral and rural areas. VIVALDI exploits the advantages of satellite communications and the open standard DVB-RCS technology, and focuses on developing the capability of such systems to offer efficient and low cost applications and services such as VoIP and other session based services that in the broader context of broadband access require special care of End-to-End Quality of Service (QoS). VIVALDI technologies: System architecture, advanced algorithms for end-to-end signalling, satellite resource allocation and media flow throughout the network. VIVALDI will suggest enhancements to the DVB-RCS standard. This will lay the foundation for full interoperability by expanding the standardization and implementation recommendations to higher layers. A standardized integrated QoS support for IP services in DVB-RCS is a major breakthrough in the development and evolution of satellite networks, which in turn will benefit the European and Global community as a whole though increased functionality and lowered cost of usage. The proposal continues already launched initiatives in ESA and in the EU, as it builds on the achievement of SatLabs, the DVB Project and ETSI specifications, as well as on several EC and national funded projects.

Main Objectives

Vivaldi will allow a generalised and affordable availability of broadband access to European users, including those in less developed regions, peripheral and rural areas. VIVALDI exploits the advantages of satellite communications and the open standard DVBRCS technology, and focuses on developing the capability of such systems to offer efficient and low cost applications and services such as VoIP and other session based services that in the broader context of broadband access require special care of End-to-End Quality of Service.

With two different equipment manufacturers involved in VIVALDI, our project aims at strengthening the competitiveness of the r and thus a larger portion of the increasing satellite access market is envisioned to be gained.

Finally, VIVALDI will contribute to the bridging of the digital divide that was recognized within the Valencia declaration for rural areas.

So far, an architecture geared towards QoS provisioning under the harsh constraints imposed by the satellite environment has been developed. In addition, a test bed has been implemented that performs header compression on real traffic and simulates the behaviour of the satellite channel. Specifically, the CRTP, Enhanced CRTP and Robust Header Compression Scheme have been implemented using the netgraph framework of the FreeBSD OS. European DVB-RCS based networks as an important goal of the EC

As a result of the above research activity, two papers have been published in the proceedings of the IST Mobile Summit 2007

Exploitation Plan


3 EXPLOITATION PLAN

VIVALDI partners will utilize the technologies developed within the project to enhance their DVB-RCS offering to include optimised usage of VoIP and thus to improve the performance and the competitiveness of their offerings.

This implies that VoIP systems will be significantly improved in performance and that the diverse equipment from different vendors compliant with the recommendations from VIVALDI will be able to play equally efficiently together in large satellite networks and in networks where satellite systems constitute one out of several technologies.

The industrial manufacturers will exploit the VIVALDI results at the end of and during the duration of the work, so as to continuously feed back into the project practical and theoretical experiences and results from real life. Intermediate or temporary results fed into SatLabs work will in a similar manner be able to form a basis for VIVALDI exploitation in the important standards process and in the work for vendor interoperability at the application layers.

The service provider partners will gain important knowledge on VoIP opportunities, user satisfaction and network and system aspects such as network load, traffic characteristics, possibilities and limitations, quality of service aspects, etc. Thus enabling them to offer better and competitive DVB-RCS based solutions.

3.2 Individual Partners

Satlynx was invited to participate in the VIVALDI project by Gilat at the end of 2005. Satlynx is very interested to participate in this project to get early visibility and experience of the latest technologies. It is also interesting for Satlynx to meet and cooperate with other European institutions and companies where we can often explore new joint business opportunities.

The VIVALDI project aims to Advance interactive Broadband satellite access by optimal convergence of session based services over DVB-RCS. VIVALDI has the overall objective to develop architectures and solutions to enable high performance and cost efficient provisioning of VoIP and other session based services like Video over IP via DVB-RCS satellite networks. DVB-RCS (Digital Video Broadcast - Return Channel via Satellite) is a European standard for the transmission of digital information via satellite. It has been specifically designed to enable broadband two-way communications via small and inexpensive Satellite Interactive Terminals (SIT) installed at customers’ premises. The terminals are also referred to as Very Small Aperture Terminals (VSAT).

DVB-RCS systems found their first applications for satellite based corporate network connections. With the decreasing price of the terminals and services, Internet access has become a key service in areas where terrestrial DSL networks are not an alternative. The main applications are remote access to corporate Intranets, email, web browsing and various other data applications, often based on VPN connections.

Driven by the deployment in the terrestrial Internet there is also a rapidly growing demand for the use of VoIP via satellite. In the consumer market, but also the small business and SOHO markets, VoIP services are becoming more and more popular. Some hundred VoIP service providers already exist worldwide and their number is further increasing additionally because of relatively low levels of regulation in many countries. Most providers support the standard VoIP protocols and low cost, mass market VoIP products; however services based on proprietary protocols like Skype are also popular.

Recent market studies indicate that about 1/3 of the residential users would replace their PSTN telephony service by a VoIP service when charged at about 10-30% lower rates and provided with comparable features and quality; 1/3 is neutral and only 1/3 would rather use VoIP as a 2nd line only option.

In the corporate market an even higher percentage of users are expected to use VoIP as 1st line PSTN replacement because of the inevitable integration with other IP applications and considerable cost advantages. A breakthrough for VoIP is anticipated following the CISCO

Exploitation Plan


announcement of the incorporation of the SIP Call Manager in their IP network products. This confirms the huge potential and importance to support VoIP via IP network access services including satellite.

Voice is currently the dominating application in addition to basic Internet access for IP connectivity. There is also an increasing use of other session based applications. The two most important examples are video-telephony/video-conferencing and high volume data transfer. Both require relatively high bandwidth to achieve acceptable performance, especially, for business applications.

The main issue with the DVB-RCS standard in this context is that it does currently not support the provisioning of Quality-of-Service (QoS) on demand. It supports the configuration of static service profiles (guaranteed bandwidth) for individual terminals or applications, but this implies that satellite resources are dedicated to that terminal or application irrespective if it is used or not. This not only results in high prices for the users, but also in a very inefficient use of the satellite capacity and hence a limited number of users who can be served by the satellite network.

The enhancements to the DVB-RCS standard developed by the VIVALDI project will address these issues, eventually aiming to support the provisioning of VoIP and other services with QoS on demand at affordable prices for the target user groups. Satlynx will learn more in the critical phase of the project in the next 6 months. If tests will be successful Satlynx will be keen to introduce this service as soon as practicable.

Newtec includes the outcomes and findings of the Vivaldi project within two of the major system lines within the Newtec Product offerings.

• 2 Way-Sat product line, providing current DVB-RCS standard based networks typically targeting the BtoB and institutional market

• The Sat3Play product line, integrates and is based on the further (probable) evolution of the DVB-RCS standard and related standards (SATMODE). The SatPlay product line is focusing on the Consumer and SoHo market. The experience and know-how obtained through the Vivaldi project will be included within the Sat3Play system. The algorithm evaluation and development of it with the Satellite resource Allocation will be re-used as basis for the Air MAC Processor (AMP) within the Sat3Play product line.

The further exploitation of the Vivaldi deliverables will be fully exploited through these business lines.

Avanti Communications plan to exploit the Vivaldi work in constructing a telephony offer for their residential and business customers.

This service will be an Avanti branded service to provide voice over IP services alongside the existing broadband internet access services provided today.

It is not intended to exploit the Vivaldi technology for all voice traffic, but rather to provide a premium service for voice traffic using the Avanti service.

Suitable marketing material will be produced nearer the time of service launch (see below for more detail).

As a member of SatLabs; Avanti will also participate in the relevant ad-hoc groups and discussions relating to QoS mechanisms in general and specifically for VoIP requirements based on the work carried out in Vivaldi.

Exploitation Plan


University of Helsinki does not feel that there is anything we could claim as "exploitable knowledge". The section seems to be focused on industrial and commercial exploitation of the results, which is of course out of scope for the universities.

As a scientific partner, AUTh is not capable of taking advantage of the acquired knowledge for developing respective commercial implementations. Nevertheless, the research that takes place in the framework of VIVALDI is establishing a solid basis for both current and future academic activity.

Gilat and Newtec will implement the designed technical solutions on their respective satellite systems. Hence, the common knowledge produced in this project will be the system architecture, the requirements and the system design. These commonly produced parts are the property of all partners, and may intellectually or economically be exploited evenly among the partners. The standardisation organisations members, and SatLabs members, will also have the right (and duty) to bring this information to the benefit of the entire satellite community generally, and to the DVB-RCS community specifically.

Gilat is planning to base its next generation networks on the DVB-S2/DVB-RCS standards and thus will be able to exploit the VIVALDI results commercially.

Dissemination and Knowledge Transfer


4 DISSEMINATION AND KNOWLEDGE TRANSFER

The approach being adopted by the VIVALDI project to dissemination and promotion of results to interested parties are here described.

The target audiences being addressed are identified, these comprise: academic & research bodies; and commercial organisations (e.g. Service Providers, DVB-RCS manufacturers and integrators as well as research institutions and the wider VoIP community), being the information to be given to each of these sectors different in depth and focus.

In order to communicate the objectives and results of the project, a set of materials will be created spanning a variety of media:

• Recommendations document to be submitted to relevant standardization bodies • Lobbying and participation by partners within different standardization groups and industry

forum • Conferences and Exhibitions • A poster to identify the project and the main objectives for use at main public exhibitions

(conferences/seminars) • A flyer, to identify and promote the project • A brochure, for advertising the project and the main objectives; • Presentation card to identify persons involved with VIVALDI • A multimedia presentation (animated demo provided on CD-ROM or over the Internet); • A conventional presentation (i.e. PowerPoint) for use at public speaking engagements; • A website, containing the most important information developed during the project, and

allowing download of related documents. • A dissemination test website where users can download and test voice quality based on the

VIVALDI recommendations.

The approach towards public exhibitions is outlined, and a number of potential events identified which will allow widespread dissemination to the target audiences.

Finally, a strategy for PR will help to create awareness through articles in trade magazines and journals.

4.1 Conferences and Exhibitions

Avanti Communications foresees possible attendance at IBC2007 in Amsterdam in September 2007

Two papers of AUTh have been accepted for presentation in refereed International Conferences, while one more paper has been submitted for publication in the IEEE Communication-Tutorials section. In particular:

Audience: Research + Industry

Gilat Satellite Networks Ltd. participated in the technical committee of the 16th Mobile and Wireless summit held in Budapest on July 2007. The Gilat prototype hub was installed in Satlynx and a real demonstration over the satellite was available in the VIVALDI booth. Gilat is planning to base its next generation systems on the DVB-RCS standard and thus will be able to exploit the VIVALDI results on commercial bases.

Gilat has provided a paper to the joint workshop organized by few DVB-RCS related projects.

4.2 Standardization Activities

All member partners will actively support the Vivaldi findings within the SatLabs group. An active liaison link has been kept between the SatLabs forum (www.Satlabs.org). The SatLabs forum is gathering all the stakeholders related to the DVB-RCS standard.

The industrial partners Gilat, Avanti and Newtec within the Vivaldi project are also active SatLabs members. Continuous alignment and synchronisation has been conducted through those members.

The following explicit sessions on the Vivaldi project and related dissemination are setup:

SatLabs meeting Rome 13-14 June 2007: Vivaldi overview presentation for SatLabs forum



SatLabs meeting Saarbrucken 20-21 Nov. 2007 (Scheduled)

Interactive discussion on preliminary results of Vivaldi and proposed recommendations for the next version of the DVB-RCS standard

Tellitec discussed the VIVALDI WP6 ("Media Flow")architecture and design with IETF ("Internet Engineering Task Force") IP/DVB work group members and the workgroup chair G. Fairhurst during March 2007 IETF in Prague. In addition it is planned to offer the IETF IP/DVB working group a presentation of VIVALDI WP6 outcomes at the December 2007 IETF in Canada (subject to approval by the IP/DVB working group and the VIVALDI EC project officer).

Target of the IP/DVB participation is: The working group has multiple international standard recommendations ongoing and in many parts already finalized. The recommendations cover most functions that are also part of VIVALDI WP6 Media Flow, but they concentrate on the specification of single functions only. They do not allow (they do in fact often prevent) a full integration of media flow components into one combined system. Therefore VIVALDI input can help IP/DVB WG members and the Internet Community to consider more integrated setups for future standardization.

University of Helsinki will contribute to a VIVALDI input to SatLabs real-life usage cases and scenarios, and will investigate which present or evolving IETF mechanisms are applicable for server-based call admission and interaction with the VIVALDI architecture; where needed/meaningful; we will contribute to their further development.

We are investigating which of the VIVALDI findings can be fed into the appropriate IETF working groups (e.g., SIMPLE or SIPPING, e.g., for a framework on the pushback signalling).

4.3 Standardization Bodies

Gilat, Newtec, Satlynx and Avanti are all SatLabs members.

Avanti is not a direct member of any other standardisation body other than SatLabs (see above) but through our close relationship with ESA and also via the UK’s trade group for hi-tech industry, Intellect (see http://www.intellectuk.org/) we can spread the results of the Vivaldi work to a wider audience.

AUTh is participating in SatNEx (Satellite Network of Excellence) and ISI (Integral Satcom Initiative) which allows VIVALDI project to establish interaction with other institutions of the same/related fields of interest.

Tellitec has taken part in the IETF Standardisation group discussion/conference.

University of Helsinki are investigating which of the VIVALDI findings can be fed into the appropriate IETF working groups (e.g., SIMPLE or SIPPING, e.g., for a framework on the pushback signalling).



4.4 Clustering

VIVALDI partners (together with the help of the EC) will identify the other EC projects relevant to VIVALDI and will look for the best way for synergy between the projects; few potential projects for such cooperation are: SatNEx, SATSIX, IMOSAN and UNIC.

Raising Public participation and awareness


5 RAISING PUBLIC PARTICIPATION AND AWARENESS

The consortium partners will all participate in the development of appropriate tools in order to achieve optimum interaction with the scientific and industrial community. In this framework:

5.1 Posters Avanti would only produce posters if the VoIP service was available from a public space, such a wireless hot-spot. If combined with the Avanti- Screenmedia service then we will be able to advertise on the screens near the access point (see later).

AUTh has prepared two posters for the Budapest mobile summit.

University of Helsinki is preparing two posters for the IST booth.

5.2 Flyers and Brochures VIVALDI has prepared a project brochure describing in a nutshell the project structure, objectives, opportunities, etcetera,

Avanti will produce the necessary marketing material when the service is available, although online promotion is probably a more effective media for the promotion of VoIP services than printed literature.

Avanti already has an interactive customer portal that will be further developed to accommodate the promotion (see above) and the provisioning of VoIP services based on Vivaldi results.

5.3 Project Website

The website has been created by AUTh in the frame of the VIVALDI project, while AUTh is also responsible for its maintenance and continuous enhancement. The main objectives of the VIVALDI website are: i) the dissemination of the project’s goals and achievements to the public; and ii) to lay the foundations for close collaboration among the project’s partners. In this context, VIVALDI website is in general open for the public, in order to allow the interaction between the project partners and the academic and industrial societies. Beyond the continuous content update, the VIVALDI website is in constant change in order to adjust to the dynamically altering needs of the VIVALDI colleagues and support the exploitation of any future activity. Optimum efficiency regarding the interaction both among the partners and between the consortium and the public is always the primary goal. Moreover, as it has been described above, via the exploitation of the upload areas, the website administration aims at giving the VIVALDI user maximum independence regarding the organization of the website, without the need for the “webmaster’s” intervention.

European Interest


6 EUROPEAN INTEREST

Links with other European co-funded programs includes:

DVB-RCS has become an ETSI international standard for 2-way, broadband satellite communications. NTC is a satellite telecommunications equipment manufacturer which has been developing its 2-way satellite system, based on the DVB-RCS standard, with the support of the European Space Agency, within the frame of the ARTES4 co-funded telecom program:

Start year Name of program Contract number

2001 DVB-RCS 15132/01/NL/US

2003 ACCESS1 17548/03/NL/US

2004 ACCESS2 18594/04/NL/US

The cooperation between NTC and the European Space Agency (ESA) is mainly technical and has allowed NTC to undertake thorough Research and Development activities and to achieve the highest technical standards. NTC first developed the basis for its DVB-RCS system which has been validated with the assistance of Aramiska, the European broadband Internet Service Provider. In subsequent ESA projects, NTC concentrated on reducing the equipment costs as well on the improvement of the system management tools.

NTC’s participation in VIVALDI, an EC-funded project, will be more application-oriented and will allow the development, demonstration and validation of Voice over IP, over satellite, in different operational networks. This is a critical service in regions otherwise difficult or impossible to access by terrestrial communication means. The synergy between the VIVALDI project and the European Space Agency support is evidenced by the opportunity to further develop services, on top of the existing system, for the benefit of the end-user. NTC will take the opportunity to specifically concentrate on the fine-tuning of Voice-over-IP performance parameters in the context of satellite resource utilisation and on the integration and validation in different real-life test cases

Tellitec:

As a leading communication software vendor the VIVALDI project partner Tellitec is providing highly innovative software products to the European and international satellite data communication industry. The outcomes of the VIVALDI project and the developed VoIP enhancement functionality will from the year 2008 onward directly feed as functional add-ons into the main products of Tellitec (namely into the TelliNet and TelliShape product lines). Thereby Tellitec will provide VIVALDI-like VoIP satellite functionality to European and international customers as well as indirectly via integration partners and equipment manufacturers in large, highly competitive satellite communication services.
