Enjoy the conference on-line. http://www.ces.net/doc/press/2008/pr081009.html The director of the CESNET association, Jan Gruntorád, is one of the 15 Europeans who received an invitation from the American National Coordination Office for Networking and Information Technology Research and Developments to come to the USA and join the American experts for discussions about the future of computer networking research. You can find further details in our press release. http://www.cesnet.cz/doc/techzpravy/2008/dxt-compression-for-ultragrid/ This report describes an implementation of DXT compression in UltraGrid, allowing for low latency, high definition multi-party videoconferencing requiring only 250 Mbps of bandwidth. This represents a substantial decrease compared to the uncompressed video stream, which requires 1.5 Gbps, while having a minimal impact on latency. http://www.cesnet.cz/doc/vyrocni-zprava/cesnet-vz-2007-en.pdf We published the 2007 annual report summarising our status, activities and results achieved in previous year. The Czech version is also available. http://www.ces.net/doc/press/2008/pr080924.html In cooperation with a group of advanced Asian Internet networks the CESNET association is organizing a unique presentation of tele-medicine interconnecting seven medical workplaces. Live footage of endoscopic and radiologic operations from medical workplaces in Japan and Taiwan will be trabsferred to Europe and remotely consulted. See more in the press release. http://www.ces.net/doc/press/2008/pr080922.html Today the CESNET academic association hosted one of the founders of the Internet, Vice-president and Chief Internet Evangelist of Google, Vint Cerf. In the Prague premises of the association, Cerf met the association's director, Jan Gruntorád; CEO of CZ.NIC, Ondřej Filip; and the director of the NIX.CZ association, Tomáš Maršálek. http://www.ces.net/doc/press/2008/pr080918.html Important names from the realm of international Internet research will be meeting on 25 and 26 September for the second professional CESNET Conference. Read more about this event in our press release. http://www.ces.net/events/2008/conference/ The CESNET Conference 08 is getting very close.

The front speaker was Dr. Eugene Yeh, Director of NCHC ? National Center for Supercomputing in Tchai-wan. The Center is running the TWAREN National Academic Network as well. By the purpose and activities, the NCHC is very similar to the CESNET association. Due to the infrastructure and the system developed during the recent years, the NCHC has become one of the leaders in the branch in Asia, while ranking very high worldwide (in TOP500 supercomputers list) as well. http://www.csirt.cz/ A meeting focused on organisational and technical aspects of the CSIRT.CZ activity took place in Malostranský palac in Prague on 15th April. CZIRT.CZ is a part of security research carried by the Ministry of Interion of the Czech Republic. The goal os this meeting was to discuss the possibility of significant Internet service providers, content and risk-service providers to participate in the CSIRT.CZ workgroup and to achieve consensus in technical and legislative aspects of network security. Andrea Kropáčová from CESNET gave the main presentation as a leader of internationally-acredited CESNET-CERTS team. She is also leading the metodical preparation of CSIRT.CZ.
