As the Internet becomes increasingly heterogeneous, the issue of congestion control becomes ever more important.

In order to maintain good network performance, mechanisms must be provided to prevent the network from being congested for any significant period of time. Michael Welzl describes the background and concepts of Internet congestion control, in an accessible and easily comprehensible format. Throughout the book, not just the how, but the why of complex technologies including the Transmission Control Protocol (TCP) and Active Queue Management are explained. The text also gives an overview of the state-of-the-art in congestion control research and an insight into the future.

Network Congestion Control:

* Presents comprehensive, easy-to-read documentation on the advanced topic of congestion control without heavy maths.
* Aims to give a thorough understanding of the evolution of Internet congestion control: how TCP works, why it works the way it does, and why some congestion control concepts failed for the Internet.
* Explains the Chiu/Jain vector diagrams and introduces a new method of using these diagrams for analysis, teaching & design.
* Elaborates on how the theory of congestion control impacts on the practicalities of service delivery.
* Includes an appendix with examples/problems to assist learning.
* Provides an accompanying website with Java tools for teaching congestion control, as well as examples, links to code and projects/bibliography.

This invaluable text will provide academics and researchers in computer science, electrical engineering and communications networking, as well as students on advanced networking and Internet courses, with a thorough understanding of the current state and future evolution of Internet congestion control. Network administrators and Internet service and applications providers will also find Network Congestion Control a comprehensive, accessible self-teach tool.

Network Congestion Control: Managing Internet Traffic

Ice cream as we recognize it today has been in existence for at least 300 years, though its origins probably go much further back in time. Though no one knows who invented ice cream, the first improvement in its manufacture was made by Nancy Johnson, of Philadelphia, who invented the first ice cream making machine in the 1840s. The Science of Ice Cream begins with an introductory chapter on the history of ice cream. Subsequent chapters outline the physical chemistry underlying its manufacture, describe the ingredients and industrial production of ice cream and ice cream products respectively, detail the wide range of different physical and sensory techniques used to measure and assess ice cream, describe its microstructure (i.e. ice crystals, air bubbles, fat droplets and sugar solution), and how this relates to the physical properties and ultimately the texture that you experience when you eat it. Finally, some suggestions are provided for experiments relating to ice cream and ways to make ice cream at home or in a school laboratory.

Just when you thought Google didn’t get “social,” Google Reader introduced a nice new feature: sharing of feeds. Click on the new “Share” tab and it allows you to publish items by label or by their star.

For example, on this address I’m sharing a couple of feeds I labeled “google.” Google also allows me to generate an Atom feed for this.

At the request of the Office of the Director of National Intelligence, the US Army Foreign Military Studies Office has created this portal to provide the general public with access to unclassified documents and media captured during Operation Iraqi Freedom. The US Government has made no determination regarding the authenticity of the documents, validity or factual accuracy of the information contained therein, or the quality of any translations, when available.

The Senate rejected a proposal to establish an independent office to investigate ethics complaints against its members, and then cleared the way to pass a broad-based ethics and lobbying bill this week.

Congressional investigators testing U.S. port security smuggled enough radioactive material into the United States last year to make two radiological "dirty" bombs, officials told a Senate panel yesterday.

In December, undercover teams from the Government Accountability Office, Congress's audit arm, carried small amounts of cesium-137 -- a radioactive material used for cancer therapy, industrial gauges and well logging -- in the trunks of rental cars through border checkpoints in Texas and Washington state. The material triggered radiation alarms, but the smugglers used false documents to persuade U.S. Customs and Border Protection inspectors to let them through with it.

"These are documents my 20-year-old son could easily develop with a simple Internet search," said Sen. Norm Coleman (R-Minn.), who chaired the hearing into covert nuclear threats before a Senate Homeland Security and Governmental Affairs subcommittee yesterday. "It is a problem when it is tougher to buy cold medicine than it is to acquire enough material to construct a dirty bomb."

Internet companies yesterday criticized legislation that would give the Federal Communications Commission only limited ability to stop phone and cable companies from blocking access to Web sites, saying the proposal would endanger the open nature of the Web.

On his last visit to Iran, Canadian-based blogger Hossein Derakhshan was detained and interrogated, then forced to sign a letter of apology for his blog writings before being allowed to leave the country. Compared to others, Derakhshan is lucky.

Which version of "The Bedford Diaries" do you plan to watch -- or to miss? Thanks to the FCC and its quixotic censorship bender, two are available. One premieres tonight on the WB. The other is already streaming into homes via the Internet -- a "webisode" that is safe, for now, from the government.
