Future satellite communication systems proposed use geosynchronous (GEO) satellites, medium earth orbit (MEO), and low earth orbit (LEO) constellations. Most of the next generation satellite systems will use fast packet switching with onboard processing to provide full two-way services to and from earth stations. One of the major service drivers is a high data rate internet access carried over ...

Network gaming is fast becoming a significant source of traffic on the Internet. Most research related to game traffic behavior on the Internet has relied on data acquired either by collecting traces at the game server, by polling the game server through queries, or by collecting traces in a LAN environment. In this paper, we study traces collected over a period of one week on the access networ...

Digital television (DTV) network is medium that transports moving images, in the form of digital video signal and accompanying sound, in the form of digital audio signal, from one point to another. However, the system may include data and control signals and hence may be thought of as a multimedia system. Various network technologies find use in the digital television production and transmissio...

broadband network control, ATM, connection management, distributed processing environment, CORBA This investigation into Network Control as a Distributed Object Application was undertaken as part of the ACTS project ReTINA (AC048). The goal of ReTINA is to develop and demonstrate an industrial strength open distributed processing environment (DPE). This DPE will support distributed real-time mu...

With the rapid growth in the popularity of and the research interest in peer-to-peer (P2P) systems, an interesting question is what the quality of network connectivity between peers in the “real world” is and what implications this has for applications. In this paper, we describe an effort called PeerMetric to directly measure P2P network performance from the vantage point of broadband-connecte...

The design of a broadband cellular network demands powerful modulation and coding under the tight constraints of affordable modem complexity and low power consumption for the mobile terminal (MT). In order to increase battery life and allow low-cost mobile equipment to be effectively integrated in such a broadband system we propose the use of a low-rate separate signaling channel (SSC) on the p...

Broadband wireless access operating in the microwave and millimeter-wave frequency windows has been actively investigated for future ultra broadband communications. The drastic increase in the throughout of each base station in these systems necessitates the use of an optical fiber backbone to provide broadband interconnections between the central office and all the antenna base stations. With ...
