Cover Story 1 Three barriers stand up against healthy B FLET’S Subscribers to the B FLET’s service are surging.  NTT now, however, cannot simply enjoy the trend because it faces three issues: (1) It cannot work out advantages for “Hikari” (FTTH service), (2) the construction support system is too busy with its present work, and (3) the service lacks applications from which income is generated.  Unless NTT can overcome these barriers, it may not only be unable to achieve the goal of “30 million subscribers by 2010,” but also lose the current momentum some day. NTT cannot work out advantages for “Hikari” (FTTH service ) Is the company failing in its attempt to differentiate the service from ADSL and WiMAX? Construction support system is too busy with its present work There is a mountain of problems to overcome before the company reaches the goal of 30 million subscribers The service lacks applications from which income is generated Connection to the Internet plus IP telephony alone means a fall in income Cover Story 2 Products that increase the effective speed of WAN tenfold immediately solve the slowness of broadband Expanding the WAN band does not improve the perceived speed.  “WAN speed-up devices” which declare that they will overcome this problem are mushrooming.  If the effective speed is improved by using these devices, the differentiation between LAN and WAN will virtually disappear, and enterprise networks will also change completely. Is delay the nemesis to throughput? Even 100-mega wide-area Ethernet cannot go beyond 7 megabit/sec? Sending data in a batch or using cached data to avoid delay Select a product according to the size of a site and the types of supported applications Communication services also provide a high-speed option Some product are developed out of load balancing devices
