inSORS Integrated Communications, Inc. Research Project to Commercial Rollout
ChevronTexaco North America
Brian Gleason
  inSORS’ development and integration efforts on the original Access Grid prototype have resulted in a stable, commercial class inSORS Access Grid platform that several large companies are currently deploying. ChevronTexaco North America was looking to increase communications between remote sites. The inSORS solution proposed to enable high performance demonstrations to business users within the context of a high value added decision-making process. Within the scope of this project, the inSORS AG would deliver an acceleration of that business process through the inclusion of remote experts. inSORS also took ChevronTexaco through the process attributes that are in the Access Grid's "Sweet Spot" based on other large customer experiences. ChevronTexaco now has four complete room based inSORS AG nodes along with several single node deployments. Their custom Virtual Venue enables private, secure communications within their corporate firewall. The venue also allows for lower bandwidth sites to connect, as well those that are not multicast enabled. Further rollout will include offshore rigs, international sites, suppliers, and partners.  
     
Lucent Technologies Test Development and Test Automation for Multi-service Switch Verification Jeffrey Dunn , Cynthia Martin
 

Telecommunication equipment design verification requires a robust mechanism to formulate standardized profile test specifications, allowing for quick and accurate feature verification, problem reproducibility, and test coverage that extends to various interworking scenarios. This poster session will provide an overview of the ISO/IEC 9646 specifications and it's applications. This test methodology, typically used for asynchronous transfer mode (ATM) conformance tests, is expanded to address diverse feature test requirements, including voice over ATM, and to reproduce customer issues. The software for Lucent Technologies PacketStar multi-service media gateways is tested and benchmarked according to ISO/IEC 9646 specifications using a diverse set of automated test tools.

 
     
Lucent Technologies Characterization of the Effects of Physical and Link Layers on IP QoS Jeffrey Dunn , Cynthia Martin
  In the traditional Internet Engineering Task Force (IETF) network model, Internet Protocol (IP) provided only an unreliable, best effort delivery service. As a result, the effects of the physical and data link layers on IP performance were ignored. In the current Internet Service Provider (ISP) environment, Service Level Agreements (SLA) require that IP based services provide certain Quality of Service (QoS) guarantees. These guarantees are often based on or enforced through physical and link layer provisioning parameters, such as Asynchronous Transfer Mode (ATM) Connection Admission Control (CAC) or Frame Relay (FR) traffic policing. In this poster, we explore standards based methods for the characterization of the impact of ATM and FR impairments, traffic policing and inter-working on IP traffic.  
     
RADVISION RADVISION's Multiprotocol Videoconferencing: H.323, SIP, H.320 Craig Colin
  RADVISION is demonstrating videoconferencing using both H.323 and SIP endpoints in a single conference connected by a RADVISION viaIP Multipoint Conferencing Unit (MCU) and Gateway. The multipoint videoconference will showcase TANDBERG H.323 endpoints and SIP-based Microsoft Windows Messenger endpoints for videoconferencing.  
     
TERENA TERENA Activities in 2003 Karel Vietsch
  TERENA is the association of research and education networks in Europe. TERENA supports joint European work in developing, evaluating, testing, integrating and promoting new networking, middleware and application technologies through task forces of technical experts and collaborative projects. The association also organises conferences, workshops and seminars for the exchange of information in the European research networking community, and promotes knowledge transfer to less advanced networking organisations. The poster will present some of TERENA's current activities. Printed materials on TERENA activities and projects funded by the European Commission in the area of research networking and Grids will be available.  
     
Stanford Linear Accelerator Center (SLAC) and the Abdus Salam International Centre for Theoretical Physics (ICTP) Bridging the Digital Divide Warren Matthews
  Last fall, a multidisciplinary group of international experts gathered for an open round table on "Developing-Country Access to On-line Scientific Publishing: Sustainable Alternatives". The meeting was sponsored by: ICTP, ICSU, IUPAP, UNESCO, TWAS and WIF. Among the 10 recommendations made, one was "To devote resources to monitor in real time the connectivity of research and educational institutions in developing countries and to encourage (and devote resources to) the development of the connectivity." SLAC is working with the ICTP to implement this recommendation using the PingER monitoring software. This poster details PingER's deployment among participating ICTP sites and reports on the performance. Furthermore it discusses the local Internet networking infrastructure and opportunities for improvement.  
     
VBrick Visual Communications for Distance Learning Using Hybrid MPEG Technologies Mike Savic
  VBrick will present a poster session on video communications over IP networks. The session will entail a technical description on distributing high quality video over LANs, the Internet, and Internet2. In order to maximize the benefit of the Internet2, you must be able to reach organizations not directly connected to I2. With the use of video compression standards such as MPEG-2 and MPEG-4 and the availability of low cost simple to use video appliances, schools and other I2 organizations can visually communicate with anyone, anywhere, on any network. The poster session will include descriptions of real world applications such as the live broadcast by the University of California - Davis, of a Smallpox lecture on February 18th, 2003. Demonstrations of MPEG-2 and MPEG-4 video compression will be available for attendees to observe.
