Optical Services over the Intelligent Optical Network
David Benjamin, Richard Trudel, Stephen Shew, and Ed Kus, Nortel Networks
Emerging intelligent optical networks address the traffic scaling challenge. Additionally, when combined with modern service management technologies, these networks open exciting opportunities for delivering new customized optical services directly to end users, allowing carriers to fully exploit the economics of optical transport.Architecting the Services Optical Network
Eve L. Varma, Sivakumar Sankaranarayanan, George Newsome, Zhi-Wei Lin, and Harvey Epstein, Lucent Technologies
The growth and expansion of networks imply a greater need for more scalable solutions and more automation for network maintenance. An intelligent optical core optimized for service optical networking, the services optical network, needs to take the best aspects of both the transport and data networking domains to meet emerging needs.On an IP-Centric Optical Control Plane
Chunsheng Xin, Yinghua Ye, Ti-Shiang Wang, and Sudhir Dixit, Nokia Research Center
Chunming Qiao, SUNY Buffalo
The authors present an experimental study on adopting and integrating the existing IP protocols and mechanisms into an optical network control plane. Although there has been much research effort on the conceptual and functional requirements for the control of optical networks, the authors focus on the design and implementation of an optical control plane.Application of Control Plane Technology to Dynamic Configuration Management
Alan McGuire, Shehzad Mirza, and Darren Freeland, BTexact Technologies
The distinction between switched-services-based and leased line services is beginning to disappear. Many network operators and suppliers are developing control plane technology for application in transport networks. This will allow faster service provisioning, particularly between network operators, and the creation of new network services. However, such systems will still require comprehensive management systems.Dynamic Lightpath Establishment in Wavelength-Routed WDM Networks
Hui Zang, Sprint Advanced Technology Laboratories
Jason P. Jue, University of Texas at Dallas
In wavelength-routed WDM networks, a control mechanism is required to set up and take down all-optical connections. Upon the arrival of a connection request, this mechanism must be able to select a route, assign a wavelength to the connection, and configure the appropriate optical switches in the network. The mechanism must also be able to provide updates to reflect which wavelengths are currently being used on each link so that nodes may make informed routing decisions.

Broadband Fixed Wireless Access as a Key Component of the Future Integrated Communications Environment
William Webb, Motorola
It is easy to forget that fixed wireless access will form part of an integrated communications environment of the future where users will have one communications device working in the home, at the office, and outdoors.Performance of Combined ARQ with SR and GBN for Broadband Wireless Systems on a 40 GHz Band Radio Channel
Noriyuki Fukui, Akihiro Shibuya, and Keishi Murakami, Mitsubishi Electric Corporation
Mobile wireless communication systems for the fourth generation are being explored. The key is broadband and high-quality communications to support multimedia services, and the use of millimeter or centimeter-wave band and ARQ is being considered to realize such communications.ATM Traffic Management in an LMDS Wireless Access Network
Josué Kuri and Maurice Gagnaire, ENST Paris, France
The authors investigate the capacity of LMDS to support ATM services in the local loop. In particular, they evaluate the performance of a MAC protocol for this system when transporting voice and IP traffic using the VBR and GFR service categories of ATM, respectively.Fixed Low-Frequency Broadband Wireless Access Radio Systems
Mina Danesh, Juan-Carlos Zuniga, and Fabio Concilio, Harris Corporation
The authors provide an overview of a fixed low-frequency broadband wireless access system for point-to-multipoint voice and data applications.A Millimeter-Wave Broadband Wireless Access Technology Demonstrator for the Next-Generation Internet Network Reach Extension
Hossein Izadpanah, HRL Laboratories, LLC
The author reports on design and implementation scenarios for a gigabit-capacity and high-data-rate fixed wireless access technology demonstrator.

Value-Added Services in the Converged Network
Yves De Serres and Lawrence Hegarty, Telebec
Now that the local market is open to competition, incumbent local exchange carriers as well as competitive LECs must not only follow the technology curve, but find a way to ride the wave of network convergence and offer innovative value-added services.Lifting the Limits on High-Speed Wireless Data Access Using Antenna Arrays
Angel Lozano, Farrokh R. Farrokhi, and Reinaldo A. Valenzuela, Bell Laboratories Lucent Technologies
Traditional wireless technologies are not very well suited to meet the demanding requirements of providing very high data rates with the ubiquity, mobility, and portability characteristic of cellular systems.A Survey of Data Multicast Techniques, Architectures, and Algorithms
Nader F. Mir, San Jose State University
The author presents a survey of architectures, techniques, and algorithms for multicasting data in communication switching networks.
