Switched Optical Star-Topology Network With Edge Electronic Buffering and Centralized Control

A star-topology local area network is designed to carry optical packet traffic, employing collision-free switching. Data forwarding is under centralized control based on scheduled resource reservation, eliminating the need for optical buffers in the central switch. Packets are stored in electronic buffers within the end stations prior to their electronic-to-optical...

Video-Streaming Applications Enabled Across Bluetooth V. 2.0 Interconnects

Bluetooth v. 2.0's enhanced datarates bring quality video streaming within scope. To harness that capacity in the presence of RF noise, various techniques should be applied. Dynamic packetization of an encoded video stream improves throughput and meets playout deadlines. Datarate swapping reduces RF loss and obviates the need for ARQ....

A TCP-Friendly Fuzzy Congestion Controller for Transcoded Video Over the Internet

Fuzzy logic control of transcoded video streams under UDP offers a flexible congestion response. The paper demonstrates that fuzzy control is compatible with existing TCP-dominated general networks. Simulations across a tight link show that fuzzy control works even when the congestion level feedback signal is not independent of the controlled...

Understanding Programming Languages

An implementation on a particular machine cannot serve as a definitional vehicle for a programming language. For one thing, there are too many extraneous details that pertain to the target machine i.e., it is far too idiosyncratic to serve as a definition of a machine independent language. Indeed, it is...

A Real-Time Parallel Image-Processing Model

Recently, a number of generalised parallel computation models have emerged, for example McColl. Efforts also persist Rinard et al to fit the serial model of processing to parallel hard-ware. The demise of the transputer and the world-wide retrenchment in the computer industry Pfister have added impetus to the search for...

Assassination of Neda, played and replayed on the Web, marks turning point for Iran

Could one bullet take down the Iranian regime? When that bullet kills an innocent young woman and her last minutes are captured on cellphone and played over and over again on YouTube, it's possible. Especially if the Iranian government continues to act with...

Spam: You just can't win

For anyone even slightly optimistic about thwarting the never-ending crush of spam I have two words: Don't bother. At the Information Security Best Practices conference at Wharton at the University of Pennsylvania I've learned the following from the first panel. Comcast's Gerard Lewis, senior...

Thinking -- Or Feeling -- Like A Computer

So an unknown billionaire named Jeffrey E. Epstein has spent millions trying to develop a thinking and feeling computer. But winds up in jail instead. This sounds eerily like a wish to build a HAL 9000 computer that was the central character of Arthur C. Clarke's science...
