NOMS 2004 Panel Sessions

Tuesday, 20 April 2004, 13:30 - 15:10 (Grand Ballroom 105)

Panel 1

OSS Platforms: Do we understand the drivers and directions for OSS Platforms? Ideal and Reality


Session Chair: Frank Korinek, Motorola, USA



Jaideep Potdar, Mahindra British Telecom (MBT), India
Seonghoon Whang, SunPS Korea
Hiroshi Kuriyama, NEC, Japan



The OSS industry is constantly changing and one of the main drivers is the evolution of IT technologies: CORBA, J2EE, OSS/J, TMF NGOSS, Web Services, to name but a few. These standards and technologies are used to build the basic Software platforms for the OSS industry, yet each evolves in it own way and can have an unpredictable impact on other technologies. This constant churn of advancing technologies creates many technical and business challenges. Under constant pressure to support new revenue-generating services, suppliers and operators must work with this mix of technologies as they develop functionality to meet their customers' needs. Even when IT developers are careful to chart a clear course through the technology mix, the process can consume considerable development resources. In the eyes of business managers, this is often perceived as an indulgence in technology fashions rather than a process vital to long-term success.

  • How can suppliers and operators get business value out of a bewildering technology mix?
  • How can activities such as OSS/J, TMF NGOSS help manage the transition from one technology to another?
  • Is Web Services the ultimate answer or simply another technology to be factored into OSS Platforms?

Panel 2

Ubiquitous Computing and Communications: Challenges in the Management of Ubiquitous Computing and Communication


Session Chair: Prof. Jong Tae Park, Kyungpook National University, Korea



Shigeki Yamada, National Institute of Informatics, Japan
Marcus Brunner, NEC Europe, Germany
Vincent Wade, Trinity College Dublin, Ireland



Recently, the ubiquitous computing and communication receives much attention due to its promising new business opportunity in IT and other related areas. In a ubiquitous environment, the surrounding contextual information acquired from sensors, GPS, and people plays very important role for the intelligent decision making process. Ubiquitous computing and communication are characterized by the invisibility of objects, proactive context-awareness and adaptation, mobility and (broadband) near field communication technology such as UWB. There have been lots of research works going on throughout the world. In this panel, we are going to investigate the issues and challenges in the management of ubiquitous computing and communication. The ubiquitous environment requires a new paradigm of management which may include ubiquitous interface management, surrounding context management, convergence management with IPv6, WLAN and 3G/4G wireless networks. In addition to these technical issues, the issues related to privacy, laws and regulation, sociological impact, and standard will be also discussed.

Panel 3

Monitoring and Controlling Networks: Have we lost control of our networks?


Session Chair: Juergen Schoenwaelder, International University Bremen, Germany



Aiko Pras, University of Twente, Netherlands
Felix Wu, University of California Davis, USA
Bert Wijnen, Lucent Technologies, USA.
Loris Degioanni, Politecnico Torino, Italy



In recent years, it has become increasingly complicated to monitor and control networks due to the fact that we are loosing our understanding of what (kind of) traffic is flowing over our networks.

  • High bandwidth links make it hard to monitor traffic in real time
  • Increasing usage of encrypted tunnels and protocols
  • Large traffic volumes generated by peer-to-peer applications
  • Undocumented and frequently changing application layer protocols
  • Increasing load due to worms and denial of service attacks

This panel brings together people from various communities to discuss whether we really face a situation where we loose control of our networks and in case we've lost control, what the implications are.

Panel 4

QoS on Multi-Service Networks: Do we know how to agree on and deliver Quality of Service (QoS) to customers?


Session Chair: Takao Maekawa, Japan Telecom, Japan



David Milham, BT exact, UK
Miki Shindo, Aoyama Gakuin University and NTT Software, Japan
Lawrence D Dunn, Cisco Systems, USA
Pradeep Ray, University of New South Wales, Australia



Networking is complex in Next Generation Networks (NGN). How do we agree on quality with customers for diverse services like voice, e-Business, online gaming, and content delivery? And how do we relate them to network performance e.g. packet loss, delay? Particularly, we aim to discuss these issues from the viewpoints of customer perceptible QoS and customer oriented QoS features.

  • Voice: The transmission delay causes difficulties, when we speak in interactive conversations.
  • E-Business: In the case of Online Trading or Internet Auction, packet loss and transmission delay become key factors for the price determination and their success.
  • Online Game: The transmission delay becomes one of the critical factors in winning or losing the game.
  • Content Delivery: In the case of live stream distributions, significant delay is prohibitive to live streaming services.

We have to assess the requirements of each actor; e.g. service customer, Internet service provider, application service provider, content service provider; depending on their purposes. The panel consists of key experts that will discuss their requirements for establishing the possible solutions and ideas for the future directions.

Panel 5

Optical Networking Management: Are standards really helping?


Session Chair: Dr. Douglas N. Zuckerman, Telcordia Technologies, USA



Takafumi Chujo, Fujitsu, Japan
Richard Graveman, RFG Security, USA
Bert Wijnen, Lucent Technologies, USA
Jae-Woo Yang, ETRI, Korea



In a sustained trend, technologies such as WDM, Gigabit Ethernet (and 10 and even 40 gigabit Ethernet), Layer-1 VPNs, and giga/tera-bit switches and routers have all drawn the attention of the telecommunications and data networking industries. These technologies provide the opportunity to improve networks in terms of simplicity, scalability and performance, as well as cost. Organizations building these next generation networks have the opportunity to realize these benefits. Industry bodies such as the Optical Internetworking Forum (OIF), IETF, T1M1, T1X1, ITU-T, IEEE, Metro Ethernet Forum (MEF) and TeleManagement Forum (TMF) have been working towards accelerating the standards and implementation of these next generation optical internetworks. Though there have been ongoing interactions between the various standards bodies, issues still remain on the role the various approaches play and when and how they will enable integration of the new networks into existing infrastructure. The newer, intelligent control-plane based networks can have major impact on network operations and the role of OSSes. In this panel, some of the telecommunications industry's key leaders will share their perspectives on the status and outlook of standards activities for realizing cost-effective, scalable, high performance networks that may use the newest optical networking technologies to their fullest potential, including impact on emerging carrier offerings such as Ethernet services and remote storage over optical networks.
