Cover Story 1

How useful is FON or public wireless LAN that everyone takes part in creating?

 

The number of FON APs (wireless LAN access points) has passed 15,000, only half a year since the FON service started at the end of 2006.  It has become the greatest-scale public wireless LAN service in Japan in terms of the number of service areas.  How useful is FON that has spread with the support of grass-roots users?  Let's unravel the mechanisms and technologies that turn the service into reality in conjunction with a test.

 

Pay full attention to security

 

I can connect to a little more than 50% of APs on the map

 

Editor-in-Chief's Interview

"Keitai or cell phones are the closest computers.  They are expected to play greater roles than now."

Mr. Tomihisa Kamada, Director, Executive Vice President, CTO, ACCESS Co., Ltd.

 

Cover story 2

Analyze edge switches to know mechanisms for price-reduction and higher functionality

 

The prices of gigabit-class edge switches are dropping sharply.  On the other hand, the products with advanced functions are mushrooming.  Although they bear the same name "edge switch," they are parting ways in terms of roles that they play. This article investigates mechanisms of the latest edge switches.

 

Latest technology that has stimulated enterprises

Report from Interop Las Vegas 2007

A new wave of quarantine networks gives a glimpse of hope to prevent zero-day/targeted attacks

 

Strategic network study

Tokyo Midtown Management Co., Ltd.

The company integrates telephones, monitoring cameras, and more into an IP network with a VoIP network constructed with about 1,000 APs

 

Educational corporation Keio Gijuku

The corporation renews its barfmail countermeasures in the intra-university network, eventually providing them to about 300,000 users including graduated students

 

Joyfull Co., Ltd.

The company reduces the sum of the travel expenses to one-fifth with video conferencing installation with a plan to deploy B FLET’S to all the 700

 

Report

Bugs in old router software that prevent the bypass of loop within IPv6 path cause FLET’S network's failure

 

NEC and Hitachi make NGN demonstrations public in their own showrooms in conjunction with booming "NOTE"

 

At last, amended ministry ordinance for high-speed wireless LAN is put in force, making 40MHz channel width available

 

Simultaneous IP retransmission enters the second stage where the scope of experiment extends to general users and an integrated service including VOD

 

Google distributes a charge-free tool that enables users to use Web applications offline

 

Array Networks launches dedicated add-on software that facilitates inter-company connection through SSL-VPN

 

Security watch

More sophisticated than ever, these are the tricks used by malware to get around antivirus measures

 

Telecom watch

Battle for winning 2.5 GHz-band starts behind the scenes: Existing 3G cell phone carriers could join it only if their investment ratio is less than one-third
