The Internet

Article Abstract:

The future of the Internet as 1999 begins seems to make it look almost invincible. Ambition keeps paying off for the Internet, and growth statistics continue to be amazing. The number of people likely to access the World Wide Web will be almost 100 mil by the end of the 1998 and 320 mil by 2002 according to International Data Corp. Internet infrastructure seemed entirely solid and stable throughout 1998; there is no worry about it in the future. Technology for the next Internet generation is being tested. US government funding is significant and may influence other countries. An optical-fiber undersea cable network called Project Oxygen is being developed and installed by CTR Group Ltd, Woodcliff Lake, NJ. It is said by some to be the most ambitious communications project of the 20th century. Java seems finally to be becoming the engineering platform of the Internet, as promised. Demands of the engineering community have made distance learning on the Internet a reality. The InterPlaNet project is to bring a single Internet communications protocol for future space missions.

The cost of quality in Internet-style networks

Article Abstract:

Quality-of-service (QoS) on a WAN can be broadly defined as how well the network does its job; more specific metrics include availability, throughput, packet loss, latency and jitter.. QoS is becoming a marketing tool; carriers now offer multiple levels of guaranteed service backed by rebates. QoS needs vary with the application. Long file transfers need high throughput and low packet loss but are not sensitive to jitter or delay; videoconferencing also demands maximum bandwidth, and is very sensitive. QoS is essentially prioritization.. Data streams from different applications converge at network aggregation points and are combined and sent over a common infrastructure. The IP protocol does not guarantee delivery of data packets; the TCP protocol runs just above it and confirms packet arrival. QoS on TCP/IP is very limited, and the IEEE and others have devised several QoS enablers, including multiprotocol label switching (MPLS), IntServ, DiffServ and Resource Reservation Protocol (RSVP).

Monkey business

Article Abstract:

The so-called 'new economy' phenomenon has created whole categories of businesses that did not exist two years ago but suddenly take advantage of new technology and business models to threaten established firms. One odd fact is that the CEOs of many of these firms are former executives of Old Economy giants. It is ironic that the creators of outdated and failing corporate cultures are suddenly rushing to operate agile new firms. The fact that Old Economy cultures are extremely resilient because they continue seemingly programmed behavior patterns even when conditions change; a company is its people, and they take the 'culture' with them when they leave at night. Executives who move to the New Economy attempt a kind of jailbreak because they recognize that the rules have changed. 'Sloth' businesses are afraid to give up legacy business practices
