Evolutionary Trends in Intelligent Networks
A number of groups are currently developing technologies aimed at evolving and enhancing the capabilities of intelligent networks. In this article the authors discuss three of these initiatives: PINT, Parlay, and IN/CORBA Interworking.
Rob Brennan, Brendan Jennings, Conor McArdle, and Thomas Curran

Using TINA Concepts for IN Evolution
The authors propose solutions that use TINA concepts for the future evolution of IN. They focus on the specific need to provide a software architecture for the IN service control function which controls the transport network through INAP.
Marcel Mampaey and Alban Couturier

The Future of the Intelligent Network
The authors examine the role the intelligent network (IN) can play as carriers move to next-generation networks. They discuss possible transition scenarios and examine how IN could interwork with the Internet and packet-based networks to produce new hybrid services.
Mark Finkelstein, Jim Garrahan, David Shrader, and Geri Weber

IN Services for Converged (Internet) Telephony
Given the convergence of the PSTN and IP-based networks, it would be advantageous to transparently support access to the existing installed base of intelligent network services from packet endpoints, while simultaneously providing newer, more advanced services to said endpoints from within the IN infrastructure.
Tsun-Chieh Chiang, Janet Douglas, Vijay K. Gurbani, Warren A. Montgomery, William F. Opdyke, Jaya Reddy, and Kumar Vemuri

Mobile Agent and CORBA Technologies in the Broadband Intelligent Network
The authors present an IN architecture that is based on distributed object and mobile agent technologies. It deviates from traditional IN in two prominent ways. First, it substitutes message-based protocols with a CORBA distributed processing environment. Second, the new architecture makes heavy use of mobile agent technology.

A Survey of Future Broadband Multimedia Satellite Systems, Issues and Trends
The need to support bandwidth-intensive multimedia services places new and challenging demands on satellite systems and networks. Flexibility, efficiency, mobility, and the ability to guarantee end-to-end quality of service are at a premium.
John Farserotu and Ramjee Prasad

Satellite Onboard Processing for Multimedia Applications
Can a satellite system compete with the capacity provided by terrestrial cable networks? If the answer is positive, and it will be shown in this article that it is, a second question arises: What new developments are required to migrate from the state-of-the-art satellite technology to such advanced concepts?
Manfred Wittig

The HALO Network^TM
The High Altitude Long Operation Network^TM is a broadband wireless metropolitan area network, with a star topology, whose solitary hub is located in the atmosphere above the service area at an altitude higher than commercial airline traffic.
Nicholas J. Colella, James N. Martin, and Ian F. Akyildiz

LMDS Systems and their Application
The author discusses LMDS performance relative to other broadband access technologies. A major remaining development task is the establishment and verification of methods for coverage of normally shielded areas. The availability of cheap repeaters and possibly reflectors for increased coverage is a must, which will significantly improve coverage.
Agne Nordbotten

Satellite Internet Services Using DVB/MPEG-2 and Multicast Web Caching
Communication satellites can be used to broadcast large volumes of data directly to extensive user groups. With the latest generation of high-powered direct broadcast satellites and the changing traffic and usage patterns in the Internet, new ways of using satellites for delivering data directly to the end user have become viable alternatives to terrestrial point-to-point networks.
Hilmar Linder, Horst D. Clausen, and Bernhard Collini-Nocker

Evolution of Optical Transport Technologies: From SONET/SDH to WDM
A new wave of equipment upgrade is unlikely to happen as current SONET equipment is just beginning to pay off for its large investment. Thus, in years to come, SONET technology, the current standard for optical fiber access, will have to make room for WDM technology in a gradual way. On its part, WDM equipment must be developed to be backward compatible with SONET technology.
Dirceu Cavendish

On Joint Protection/Restoration in IP-Centric DWDM-Based Optical Transport Networks
Recent advances in WDM technology are now beginning to shift the focus more toward optical networking and network-level issues. Providing survivability at the optical layer is inherently attractive, but whether it makes practical sense, given similar mechanisms that are already available at the higher layers, poses serious challenges and raises many questions.
Yinghua Ye, Sudhir Dixit, and Mohamed Ali

Dynamic Resource Allocation for Quality of Service on a PON with Home Networks
Earlier efforts on optical access concentrated on the design of PONs for the collection and distribution portion of the access network. A possible evolution scenario for these types of access networks could be the SuperPON system, which exploits all possible upgrades of an FSAN APON system.
