Integration Applications: The Next Frontier in Programming

The programming world is undergoing a fundamental shift from monolithic applications to integration applications. Integration applications are created by coordinating and extending existing applications, protocols, frameworks, and devices rather than building from scratch. In this talk I'll describe why integration applications will dominate software development in the years ahead and what this means for the way we develop programs. In particular, some of the things that are taken for granted today, such as strong typing and inheritance, may not make sense in the future.

John Ousterhout is CEO of Scriptics Corporation, a company developing commercial applications around the Tcl scripting language while also advancing the open source Tcl/Tk core. Before Scriptics, John was a Professor of Computer Science at U.C. Berkeley and Distinguished Engineer at Sun Microsystems.

IP Telephony - Protocols and Architectures
Melinda Shore, Nokia IP Telephony Division

Rapid developments in IP telephony have, over the period of just a few years, moved us from a situation in which there were no standards into one in which there are many, often conflicting, standards. Different standards bodies, such as the Internet Engineering Task Force (IETF), the European Telecommunications Standards Institute (ETSI), and the International Telecommunications Union Standardization Sector (ITU-T) have developed their own models of how telephone systems should be constructed on packet networks, and what the interfaces to public and private telephone networks should look like. This talk provides an overview of current and developing protocols for IP telephony, as well as of the architectures which they were designed to support. Particular attention will be given to the interconnection of packet-based telephone systems and traditional, circuit-based telephony.

Will There Be a Transition to IPv6?
Allison Mankin, USC/ISI; Guy Davies, Worldcom UUNET-UK

In January 1995, after several years of work on multiple candidates, the Internet Engineering Task Force began the development of the consensus next generation of the Internet Protocol. The driver was the exhaustion of IPv4 address space. Four years later, that address space is indeed very scarce, but, notwithstanding some notable activities, such as the 6BONE, there appears to be little transition to IPv6. Davies and Mankin will describe the current tradeoffs of subscribers, equipment vendors and ISPs. They will evaluate the stability of the Network Address Translator (NAT) solution for address scarcity, present some expectations about device and embedded system uses of IPv6, and generally cover the question of whether there will be a transition to IPv6.

Paving over Road-Kill on the Info Superhighway: Observations on the State of the Art in Incident Handling
Jim Duncan, Cisco Systems

Current trends in computer security incident-handling range from comedic to disturbing. For every incident concluded with the terse finality of a synopsis from Joe Friday, ten or a hundred are mangled by the Keystone Kops. The lure of incident handling is inescapable: when a site is cracked, the sysadmins mount up a posse to haul the perpetrators to justice. Unfortunately, cyberspace doesn't map very well onto pre-existing concepts of ethics and law--as a result, vigilantes shoot the innocent and criminals go free. Moreover, the tendency to cover up incidents denies due process to the parties involved, deprives the users of an education, and elides information that should be part of public discourse. This talk will survey the state of the art, with a view from above the alleys of the cyber village, and will propose some improvements.
