Internet telephony: going like crazy
Article Abstract:
Internet telephony, also known as voice over Internet protocol (VoIP), is one of the fastest-growing technologies, predicted to increase by 5000 percent by 2004. The primary benefit for residential customers is lower fees for long-distance calls because when a call is made using VoIP, there is no charge, beyond what an Internet service provider (ISP) charges for access, for transmitting IP packets across the Internet. For businesses, VoIP means voice and data networks can be consolidated, and all the services native to a digital network become accessible. In the future, costs will come down as devices that integrate hardware components onto chips that combine features of a traditional microprocessor with those of a digital signal processor (DSP).

Diversifying Internet delivery
Article Abstract:
Increased Internet use has begun to cause such congestion that alternate means of data transfer will need to be implemented to keep the Internet from slowing considerably. Differentiated services (DiffServ) technology may eventually replace existing Internet protocols. With DiffServ, data packets are assigned varying levels of priority that determine how they are routed across the Internet. This may become increasingly important as voice and data transmissions begin to share the same bandwidth. Current technology treats all packets as equal, whether they are voice, multimedia, email, or any other type of data.

Building the wireless Internet
Article Abstract:
The 'wish list' architecture of an ideal wireless Internet implies certain reqirements. For example, mobile users should be given the full Internet experience rather than a limited menu of specialized services. The wireless Internet must be fast, and it should use power efficiently because most network-attached devices will run on batteries or fuels cells. The wireless Internet will probably require a multitude of nanocells. Satellite-based wireless Internet arrangements are not likely to succeed because satellite systems' cells are too big.
