Internationally acclaimed violinist and conductor Pinchas Zukerman doesn't let a little thing like a few thousand miles stand in the way of reaching his students.
Using high-definition videoconferencing technology available through the Internet2 network, he can give individual instruction to students half a world away with CD-quality sound and DVD-like images.
On August 9th, 2004, the U.S. Federal Communications Commission (FCC) took a major step toward mandating the creation and implementation of new Internet Protocol standards to make all Internet communications less safe and less secure. What is even worse, the FCC's ruling will force ISP's and others to pay what may amount to billions of dollars to ensure that IP traffic remains insecure.
Security innovations being built into switches are attracting attention from buyers who not long ago focused primarily on feeds and speeds.
Network executives say they need all the help they can get to cope with today's threats. They are eager to use new switch-based security schemes - such as the ability to quarantine viruses and enforce policies - being touted by Alcatel, Cisco and Enterasys Networks, among others. In the forefront:
Japanese network operator NTT DoCoMo has reached a significant milestone in the journey towards fourth-generation mobile services.
The company announced earlier this week that it has managed to achieve a maximum connection rate of 300 megabits per second, and an average rate of 130Mbps, using cutting-edge wireless technologies.
Competition from cable companies means that rival fixed-line telephone companies will soon be forced to offer significantly faster digital subscriber line services than are on the market today, according to Nortel Network's chief technical officer.
Speaking in London on Monday, Nortel's Greg Mumford predicted that broadband services would grow significantly faster over the next few years, as pressure grows from users demanding more innovative features.
Among the open-source community there's a commonly used acronym, "POGE." It stands for the "principle of good enough," and it's meant to emphasize the open-source tenet that you don't begin a project by over-engineering the end result.
Instead, you do what is "good enough" and then let things improve over time.
For the second learning session on Help Net Security, we've got Steve Woo, Riverhead Networks Vice President of Marketing and Business Development, discussing the threats of Distributed Denial of Service attacks. Since the making of this audio session, Riverhead Networks was acquired by Cisco Systems.
In this ten minute audio, Mr. Woo introduces the listeners to the enormous threat of Distributed Denial of Service attacks in the Internet era and gives his opinion on what should organizations do to stop them.
Researchers found a serious security flaw that left core Internet technology vulnerable to hackers, prompting a secretive effort by international governments and industry experts in recent weeks to prevent global disruptions of Web surfing, e-mails and instant messages.
Take a trip to Korea or Japan, and you will immediately have a new appreciation for the definition of broadband.
These are distributed denial of service attacks small enough to fly below the security radars of ISPs and law enforcement agencies, but potent enough to shut down cable or DSL modems connections. As evidenced by my inability to do anything about an attack on my connection (which I use to get my job done, but is shared with other family members for personal use), the perpetrators can wreak havoc without fear of reprisals.
