TWIST 99 aims to gather participants from industry and academia who are researching or developing software technologies that scale to the Internet. Internet-scale namespaces have emerged as a crucial issue in scaling software and network technologies to the numbers of people, devices, and agents online. Every namespace, from MIME type to stock symbol to domain name, represents a bundle of political, economic, social, and technical decisions. Many namespaces are bumping into new limits to growth: human-friendly names for Web resources, the domain name service, public key infrastructures (PKI), and ad-hoc federation of embedded computers a la Jini, to name four. These are not merely limits of sheer massiveness: the latest generation of commercial directory servers claim to vend hundreds of millions of names with ease, as do planetary-scale Web search engines.

The TWIST series provides a forum for discussion and enables quick dissemination of current ideas within a well-targeted audience. The goals of the workshop series are developing a better understanding among the different communities of interest, improved definition of requirements for scaling to the Internet, better appreciation of the application domains that require or benefit from this approach, and suggestions for fruitful research directions.

This engaging two-day workshop is being convened with the following goals in mind:

New challenges specific to Internet scale include:

TWIST 99 is a two day event with a single track of invited speakers structured as:

Thursday, August 19: Presentations on Internet-Scale Namespaces
Friday, August 20: Intensive group work to develop scenarios of Internet scale naming, and
                                            identify cross-cutting issues for Internet scale namespaces.

The current list of speakers includes:

TWIST '99 is a follow on to the highly successful Workshop on Internet Scale Event Notification (WISEN) held on July 13-14, 1998 at UC Irvine. In response to WISEN's positive reception, IRUS has evolved the event into a workshop series with a broadened scope.
