ATM: backbone to the future
Article Abstract:
Fast Ethernet switches can provide a limited amount of raw bandwidth, but ATM backbones have the potential to save networks inundated with multimedia demands. ATM expands high-bandwidth lines and manages multimedia by dividing data into small, fixed-size cells that make traffic less congested and more predictable. While Fast Ethernet is less expensive and easier to integrated into existing networks, ATM is a competitive solution when creating a network from scratch. Additionally, the ATM Forum is developing standards, specifically the Multi-Protocol Over ATM standard, to help simplify the process of running Ethernet over ATM switches. ATM Forum members are also seeking ways to make IP connections run more smoothly with ATM technology. Despite these advances, ATM's benefits cannot be fully utilized until there is software, which requires a solid API.

ADSL jumps into the race
Article Abstract:
Phone companies are developing ADSL technology to increase bandwidth in traditional phone lines and enable them to compete with cable-modem services. ADSL, an XDSL modem technology, is becoming increasingly attractive with the introduction of new modulation and compression techniques. ADS's minimal need for infrastructure upgrades and its modem-to-modem technology enables equipment to be upgraded customer by customer. The guaranteed bandwidth of dedicated lines provides greater security, which will appeal to small businesses and satellite offices. ADSL is picking up speed and is catching up to its competition, cable modems. This increasing speed, coupled with the reliability of ADSL, has prompted US West and Bell Atlantic to prepare for commercial ADSL service within two years.

Pipe dreams.(broadband portals) (includes related articles on Snap's broadband service, cable modems, DSL))(Internet/Web/Online Service Information)(Cover Story)
Article Abstract:
DSL and cable modems have arrived, bringing with them the promise of new kinds of content such as multicasts and audio/video-on-demand, delivered via broadband portals. So far, however, content providers say a larger audience is needed to justify more effort and expenditures on their part. Meanwhile, a Yankee Group survey shows that consumer interest in broadband is increasing. For example, of 2,000 online US homes contacted in 1999, 41 percent say they are 'very interested' in broadband, up 25 percent compared with the previous year. A battle is looming between cable operations and DSL vendors.
