A Two-Tiered On-Line Server-Side Bandwidth Reservation Framework for the Real-Time Delivery of Multiple Video Streams

The advent of virtualization and cloud computing technologies necessitates the development of effective mechanisms for the estimation and reservation of resources needed by content providers to deliver large numbers of Video-On-Demand VOD streams through the cloud. Unfortunately, capacity planning for the QoS-constrained delivery of a large number of VOD streams...

Scalable Coordination Techniques for Distributed Network Monitoring

Emerging network monitoring infrastructures capture packet-level traces or keep per-flow statistics at a set of distributed vantage points. Today, distributed monitors in such an infrastructure do not co-ordinate monitoring effort, which both can lead to duplication of effort and can complicate subsequent data analysis. The paper argues that nodes in...

Efficient Monitoring of End-to-End Network Properties

It is often desirable to monitor end-to-end properties, such as loss rates or packet delays, across an entire network. However, active end-to-end measurement in such settings does not scale well, and so complete network-wide measurement quickly becomes infeasible. More efficient measurement strategies are therefore needed. Previous work, examining this problem...

Scalable Overlay Multicast Tree Construction for Media Streaming

This paper compares various methods to construct multicast trees between end-systems, that vary in terms of implementation costs and their quality of mapping from logical overlay to physical network. They describe several algorithms that make trade-offs between algorithmic complexity, physical link stress and latency. While no algorithm is best in...

Computers have speed limit as unbreakable as speed of light, say physicists

A pair of physicists have shown that if processors continue to accelerate in accordance to Moore's Law, we'll hit the wall of faster processing in roughly 75 years. The curtain will eventually come down for silicon in today's manufacturing methods once engineers can no longer further shrink...

Chemical mind hacking: legit, or corporate cheating?

There is an absolutely fantastic article by Margaret Talbot in this week's New Yorker about the use of "neuroenhancers" -- that is, neuroenhancing drugs such as Adderall, Ritalin and Provigil that are typically prescribed for ADHD and dementia -- to effectively "hack" the brain and coax more productivity from it....

GPL's cloudy future

One of the things about getting older is that you learn to ignore things until you have to do something about them. It's a learned efficiency, I suppose, rationing your increasingly precious time out to the unceasing demands upon it. I finally realized I have to do some serious thinking...
