MULTIPROTOCOL LAMBDA SWITCHING: COMBINING MPLS TRAFFIC ENGINEERING CONTROL WITH OPTICAL CROSSCONNECTS - The authors describe an approach to the design of control planes for optical crossconnects which leverages existing control plane techniques developed for MPLS traffic engineering. The proposed approach combines recent advances in MPLS traffic engineering control plane constructs with OXC technology to provide a framework for real-time provisioning of optical channels.
ARCHITECTURES AND PROTOCOLS THAT ENABLE NEW APPLICATIONS ON OPTICAL NETWORKS - The authors first discuss how advances in networking architectures and protocols can complement advances in optical communications research to increase the overall value of optical networks by enabling more applications. A review of existing optical networking solutions is then provided along with a classification of different types of optical networks.
THE APPLICATION OF OPTICAL PACKET SWITCHING IN FUTURE COMMUNICATION NETWORKS - Telecommunication networks are experiencing a dramatic increase in demand for capacity, much of it related to the exponential takeup of the Internet and associated services. To support this demand economically, transport networks are evolving to provide a reconfigurable optical layer which, with optical cross-connects, will realize a high-bandwidth flexible core.
THE PERSPECTIVE OF OPTICAL PACKET SWITCHING IN IP-DOMINANT BACKBONE AND METROPOLITAN NETWORKS - The authors analyze the rationale and technical solutions for the use of optical packet switching techniques for both backbone and metropolitan applications. They also provide information on state-of-the-art technologies available for medium-term product development.
ALL-OPTICAL PACKET SWITCHING FOR METROPOLITAN AREA NETWORKS: OPPORTUNITIES AND CHALLENGES - All-optical packet switching provides high throughput, rich routing functionalities, and excellent flexibility. These characteristics make it an excellent candidate for next-generation metropolitan area networks, which will be much more dynamic and demanding than today's networks.
SATELLITE-BASED INTERNET: A TUTORIAL - In a satellite-based Internet system, satellites are used to interconnect heterogeneous network segments and to provide ubiquitous direct Internet access to homes and businesses. The authors present satellite-based Internet architectures and discuss multiple access control, routing, satellite transport, and integrating satellite networks into the global Internet.
VOICE OVER IP SERVICE AND PERFORMANCE IN SATELLITE NETWORKS - Satellite systems, as an integral part of the global communications infrastructure, already have an increasing portion of their capacities used to carry data packets, and with their global coverage and reach to remote areas are well positioned to enable growth of VoIP services.
EFFECTS ON TCP OF ROUTING STRATEGIES IN SATELLITE CONSTELLATIONS - The authors introduce the types of satellite constellation networks, and examine how overall performance of TCP communications carried across such a network can be affected by the choice of routing strategies used within the network.
INTERACTIVE WEB SERVICE VIA SATELLITE TO THE HOME - The authors describe an investigation and simulation of a return path VSAT link designed specifically for delivery of Web traffic requests to a base station and thence via a terrestrial link, using the Internet, to a Web server. They focus on the MAC protocol to support such a satellite channel and on modeling the whole service from traffic generation through transport, network, and MAC layers to the physical channel.
INTERACTIVE CHANNEL FOR MULTIMEDIA SATELLITE NETWORKS - The return channel of the interactive channel for multimedia satellite networks underwent final standardization by ETSI in early 2000. The authors review the system concept of a typical implementation. They also explain the key features of the return channel air interface, from transmission parameter to login procedure.
TOPICS IN BROADBAND ACCESS - DOCSISTM CABLE MODEM TECHNOLOGY - The authors provide an overview of the cable modem interface standard. This standard is the foundation for high-speed access to content on the Internet being offered by North American cable operators.
TOPICS IN BROADBAND ACCESS - METHODS OF UPSTREAM POWER BACKOFF ON VERY HIGH-SPEED DIGITAL SUBSCRIBER LINES - The author describes the near-far problem in the upstream direction of VDSL, which results when the lengths of VDSL loops in a binder vary significantly. Methods of upstream power backoff to mitigate the near-far problem are also described.
