Can the Internet ever be trusted?

Over the past few months, disturbing studies have come to light indicating fear of using the Internet. The fear is directly related to all the bad press and user experiences with viruses, worms, Trojans, spyware, malware and spam that inhabit Internet communications. Operating system flaws that hackers can exploit have added the potential of identity theft to the growing list of user fears. Keeping software patches, virus definitions and e-mail filters up to date has become a time-consuming administrative nightmare.

Opinion: Is it time to re-engineer SNMP?

For more than a decade, SNMP has been the basis for all IP network and systems management. However, as with all legacy software, there comes a time to break with the past and move into the future with a new management construct and architecture that meets the changing demands of vendors, customers and services.

Policy — yours or mine

In the future, companies will use business-based policy management to control costs, allocate finite infrastructure resources, manage application access and police security. With the advent of on-demand and utility computing, as well as compute and storage virtualisation, corporate concerns about policy ownership issues have risen to new heights. The main concern is that business-based policy must be end to end and be set by corporate management, then translated into deployment policies within the policy islands of infrastructure operations; user workflow; network, storage and server infrastructure; and application software.

Are we running out of wireless spectrum?

Recently I read with surprise an article in The New York Times' business section predicting doom and gloom for the U.S. wireless communications industry. According to the article, several studies submitted to the U.S. Federal Communications Commission by the Department of Defense and nonprofit and healthcare organizations indicate that it would be costly and almost impossible to relocate spectrum to accommodate new user demand for broadband wireless. The article implies that we are running out of spectrum; therefore, broadband wireless may be a dead issue.

The Internet Is Dead; Long Live the Internet

As an industry analyst I spend a lot of time traveling the world and talking to communications users, equipment and application vendors, service providers, entrepreneurs, investment bankers, venture capitalists and investors. What they all have in common is a strong belief that Internet technology will lead the way into a future communications age rather than an information age.

The Frustrations of a DSL Buyer

Industry analysts are often caught up with projecting a vision of the future rather than the reality of the present. Take the implementation of broadband services, for example. Digital subscriber line (DSL) was going to be the simple solution that brought inexpensive broadband services to the home and small business. But DSL's potential is being impeded by service provider provisioning incompetence and politics.

Guest column: Application service providers: old idea made new

Well, it had to happen. With the advent of the application service provider (ASP), the cycle of computing trends has come full circle. The introduction of outsourced Web-based shared resource business applications has returned us to the bygone days of service bureaus and time-sharing. The computer applications have changed from payroll to enterprise resource planning (ERP), and the communications have changed from private-line SNA or TTY dial-in to IP-based internet, intranet and extranet access -- a new age but the same old idea. Has Intel and Microsoft's worst nightmare come true? Is this the end of personal computing and the enterprise? Is the ASP market real?
