• MetaCentre 2000–2001 yearbook• book about IPv6With the last mentioned publication, the association commenced collaborationwith the Neocortex publisher, which publishes specialized computer literature.The CESNET edition has been formed – its authors should be represented bythe researchers working on the research plan. This creates a new space forpublishing books dealing with the topic of advanced network technologies andtheir applications. The books will be distributed through standard distributionchannels for specialized literature and thus easily available to readers.In 2002, we continued in our collaboration with the Lupa online magazine,focusing on the Internet topic. We published nearly 30 articles here that arethematically linked with the research plan. The articles dealt mainly with theadvanced network technologies and services.The number of technical reports from 2002 roughly matches the numbers from2001. We published 18 technical reports. Approximately one half of the reportsare written in English, and the rest in Czech.We continued publishing the Datagram newsletter, in which we inform associationmembers and other institutions about capabilities of the CESNET2 networkand activities related to the network development. Four issues of the newsletterwere published in 2002.Most of the aforementioned publications (with the exception of the book aboutIPv6) are freely available in electronic form on the websites of the associationat www.cesnet.cz and meta.cesnet.cz.17.3 Public Events and Other PresentationFormsThe most important public presentation event was the commemoration of the10 th anniversary of the Internet start in the Czech Republic. On this occasion,the association organized a celebratory meeting called 10 Years of the Internetin the Czech Republic.The meeting took place in the Prague Karolinum on Wednesday, 13 February,exactly ten years after the ceremonial initiation of the Internet network operationin the former Czech and Slovak Federative Republic. In the afternoon blockof lectures, both foreign and home guests presented a set of lectures focusedon the history and prospects of this network. The afternoon part of the meetingwas dedicated to panel discussion with the topic “Where is the Internet heading?”186 High-speed National Research Network and its New Applications 2002
The meeting was broadcast live via the Internet and records of individual lecturesand the panel discussion are available in our video archive. The tenthinland Internet anniversary received a significant response from the specializedpress.Figure 17.2: 10 Years of the Internet in the Czech Republic meetingThe association also participated in organization of the traditional conferenceentitled Broadband Networks and Their Applications, which is hosted by PalackýUniversity in Olomouc. On this occasion, as well as at other specialized conferencesand seminars, members of the research team presented many reportsdedicated to the results achieved within work on the research plan.17.4 2003 PlanWe assume that our activities will continue in the same direction in the nextyear. We will concentrate mainly on the continuous updating and developmentof www.cesnet.cz and publishing of the Datagram newsletter and technical reports.We would like to expand our multimedia archives with an archive of freeto-usehigh-quality digital photographs.High-speed National Research Network and its New Applications 2002187
