Within the past year we have seen a steadily declining level of performance of the Internet, and many wonder when, or whether, we might expect to see characteristics more typical of the network during the last year of the NSFNET program. As with any two-year-old, there seem to be days when the Internet behaves well and days when one wonders whether the atrocious behavior that it exhibits is somehow deliberate, designed to test the patience of its higher education creators, and determined to be forever incorrigible.
Privatization of a service is typically expected to yield advantages such as lower costs (or better cost performance), improved functionality, and rapid deployment of advanced technologies. Such advantages have not been realized following the privatization of the NSFNET, and many factors have combined to slow their realization. We are witnessing an unprecedented explosive behavior being driven by millions of new users, significant increases in use by the commercial sector, and the impact of browser technology that was not in existence twenty-four months ago. This evolution encompasses education, the private sector, and society as we create an infrastructure destined to become as pervasive as the electrical grid, telephones, and our system of roads. These developments are transforming the way we learn, conduct commerce, communicate, and interact with each other. At the moment our demand for bandwidth appears insatiable, and a real question is which parts of the commercial sector will step forward to meet the need, not whether the need will be met.
The above is not exactly breaking news. The following comment is from a 1994 hearing of the U.S. House of Representatives Subcommittee on Science:
The growth of both the number of users and the applications of the Internet (that element of the NII which is available and working effectively today) has astounded even those of us who have been its most optimistic proponents for many years. It has grown from a resource used primarily by the research and education sector as recently as five years ago to a significant force within the nation's business sector today. It will become a major element of our global competitive posture within the decade.1
The intent of this article is to reflect on why there are problems today and to discuss a number of efforts focused on fixing them. I will begin with a discussion of why the Internet appears to be broken, including some observations about both commercial and higher education use of the network, and conclude with a brief report on initiatives currently under way within the higher education community that are focused on creating the next generation of Internet applications, services, and technologies.
Many elements are in rapid evolution, and these will continue to contribute to the turmoil that seems to be the norm today. Discussions in several areas follow.
The Internet is a collection of cooperating interconnected TCP/IP networks. With no centralized management or administration function, troubleshooting and administration are complex and time consuming. In addition, performance is unpredictable, reliability varies greatly among Internet Service Providers (ISPs) and there is (are) no mature or common security standard(s) for virtual private networks.2
First, recognize the nature and maturity of the technology. In a limited defense of the ISPs, ranging from large interexchange carriers to some of our smallest providers, the fact that the Internet works at all is somewhat amazing. There has been no other technological evolution that has grown at the rate of the Internet, and I can think of no other infrastructure, of any kind, that could withstand the pressures inherent in that growth and still be functioning. During the last months of the NSFNET we experienced growth rates of 10 percent per month, astronomical by any standard, and current estimates are that traffic now doubles on today's Internet at a rate more than twice that of the NSFNET days.
Remember that the "privatized" net is less than two years old, and that we are in the midst of a very difficult transition. We can expect turmoil for some period to come. Not only are there now in excess of 5,000 Internet Service Providers in this highly immature industry, with its equally immature technology, no one -- repeat, no one -- predicted things such as real-time applications on the Internet becoming popular and commercial so quickly. Examples of these include packetized audio, video, electronic commerce, computer telephony, World Wide Web searching, and other Web- based applications. These are only beginnings as the entrepreneurial capabilities within the nation become unleashed. Note that the continued rapid change in all areas of technology (networking, hardware, software) makes any planning short-range at best. Recall that Mosaic was introduced about three years ago.
The question of payment and electronic transactions is a typical problem and a good example of the above. We tend to think of typing in a credit card number as the mechanism for payment on the Internet, and we often hear that until the "security" problem is solved there will be no serious commerce conducted on the Net. However, not only does society appear generally quite willing to enter credit card numbers onto a Web page (indeed, there are some who argue that such a mechanism is at least as secure as providing the number to an unknown telephone solicitor), there are now many Internet payment mechanisms in varying stages of development or existence (for example, First Virtual, NetBill, Ecash, and CyberCash).4 Entrepreneurs quickly rush to fill voids if there is money to be made; if none of the existing schemes works satisfactorily, then there is little doubt that someone will invent one that will.
I should note that the CICNet network, as a second-tier provider (one provider away from the Network Access Points), also has been adversely affected by many of the same external problems that universities see -- large packet loss, congested paths through the Net, provider outages, hackers attempting to cause network nodal failures, and the like. Our backbone provider's network (and we think our provider is the best in the business) continues to show congestion at the edges, even though they have made remarkable progress in the interior of their network. Many of the low(er)-end providers oversell their trunk lines by ridiculous amounts so it is hard to feel sorry for them when these trunks fill up.
It is also important to understand that the solutions of the past are generally not available. For example, the original R&E mission of many of the old NSF-sponsored regional networks (SURANET, in the southeastern United States, for example) is no longer relevant, either because the network is gone, sold by higher education to for-profit organizations, or because the network has become for-profit in its own right, or because the network has not been able to sustain itself financially and is now out of existence. The focus of the new incarnation of most of these organizations tends to be in arenas other than higher education. Not all, but many, have this problem.
We need access to a next-generation network supportive of research and education. Applications abound, and include things such as:
Serious stuff, and beyond our capability today. Indeed, there is reason to anticipate that such requirements, or their counterparts next year or in the next decade, will be forever beyond the ability of the commercial sector to provide at an affordable price. As Douglas Van Houweling said recently in a presentation at the University of Michigan on visualization and virtual reality, "If a picture is worth 1,000 words, then a moving picture is worth 100,000 words, and a virtual environment worth 100,000,000 words. So to realize the full impact of such developments, we need new media and the deployment of massive bandwidth in a multi-nodal networked environment."
For the sake of completeness, it is important to note two very important activities directly related to the applications space. Most readers are probably very aware of the excellent work being accomplished by the Coalition for Networked Information (CNI) and the National Learning Infrastructure Initiative (NLII), the former focused on intellectual property issues and the latter on the evolution of an applications set which realizes the potential of multimedia in a networked teaching and learning environment.6
One of the most important initiatives on the national level is the Internet II effort. While a number of people began working on the idea of a new network for higher education shortly after the privatization of the NSFNET, initiatives to create national consensus really began at a conference held in Monterey, California, in September 1995. Immediately following that meeting a group of individuals formed an ad hoc group called the Monterey Futures Group (MFuG) to begin the effort of specifying both technical and application requirements for such a network. The work of the MFuG group included both an initial discussion of the future application space needed by higher education and a first cut at the technical requirements for its support.7
The work of the MFuG group was transitioned to the Networking and Telecommunications Task Force (NTTF) during a FARNET/NTTF-sponsored meeting in Washington this past April. As follow-up, FARNET then obtained funding for a nationally attended workshop held in Colorado Springs this past August and which was again jointly sponsored by a number of professional societies and organizations.8 Key outcomes of the meeting were a national discussion on the next steps and an accelerated effort by the leadership within the nation's Research I universities to launch the Internet II initiative.
That said, there is little in the above initiative that helps the rest of the college and university sector, community colleges, K-12, libraries, and the like. It is here that I think we need to quickly turn our attention. We have a very difficult problem. At the least we need a forum to discuss the problems of the larger community so that some common understandings might evolve into proposals for solutions.
The challenge to be addressed might be stated as "Internetting for the rest of us." Now that the Research I universities have launched the Internet II initiatives, how should the remainder of the academic community best position itself to participate, while realizing the fullest potential of current and evolving Internet technologies and services? I am sure that CAUSE would be amenable to working something into its general agenda if there is sufficient interest. So, too, would FARNET -- the Federation of American Research Networks. Perhaps some kind of joint forum would be appropriate, and, as a point of reference, FARNET issued a press release outlining its "... plans to focus on a broad range of initiatives in 1997 that will extend the next generation Internet and its technologies, applications and services to the broader education, research and public services communities."9
The privatized Internet as a two-year-old? It is behaving exactly as one would expect, and, as we tend to view most two-year-olds, we look forward not only to passage of the phase, but to the unlimited future that harbors our most optimistic hopes and aspirations for any of our children. We are increasingly seeing an analogy, initially prepared by Ivan Campos for the Colorado Springs meeting, 10 as explanation of where things stand today. His claim is that we have evolved the Internet from an advanced research project to today's commercial service, and that we are beginning a second cycle to create the next generation, this one capable of supporting applications which are now quickly evolving within higher education and which cannot be accomplished on today's infrastructure. Stay tuned.
