The rapid development of the Internet and the World Wide Web has created a global network that will soon become a physical embodiment of the entire human knowledge and a complete integration of the global information activities. It is believed that one of the user-friendliest and natural approaches for accessing the network will be via human voice, and the integration of spoken language process...

The ability to control and monitor network traac is important for understanding the behavior of, and developing control algorithms for, broadband networks. In this paper, we report on a traac generation and QOS monitoring system we built on a Hewlett-Packard Broadband Series Test System. The traac generator is capable of continuously generating multiplexed ATM cell streams in real-time correspo...

Wireless ATM (WATM) will be used to support broadband applications for future generation mobile services. To achieve this, the existing ATM protocol must be augmented with mobility management capabilities. One of the important components of mobility management is the ability of the network to seamlessly reroute existing connections to different parts of the network. To date, a number of schemes...

A number of satellite communication systems have been proposed using geosynchronous (GEO) satellites, as well as low earth orbit (LEO) constellations operating in the Ka-band and above. At these frequencies satellite networks are able to provide broadband services requiring wider bandwidth than the current services at C or Ku-band. As a consequence, some of the new services gaining momentum inc...

Self-organized criticality is an attractive model for human brain dynamics, but there has been little direct evidence for its existence in large-scale systems measured by neuroimaging. In general, critical systems are associated with fractal or power law scaling, long-range correlations in space and time, and rapid reconfiguration in response to external inputs. Here, we consider two measures o...

Satellite is considered a vital technology for enabling ubiquitous access to broadband services in many countries. This paper explores provision of IP-based broadband satellite access with Quality of Service (QoS). It analyses a set of example scenarios, based on the recently published DVBRCS2 standard involving web and voice traffic. It specifically explores the interaction between Bandwidth-o...

The US has a long history of telecommunications policy aimed at providing equitable access to information and communication services. In this paper we examine the most recent of these efforts, municipal wireless broadband Internet networks. Using three cases (Philadelphia, PA; San Francisco, CA; and Chicago, IL) we examine how social inclusion is expressed in the digital inclusion policy articu...
