2002 - cesnet

men. We designed the basic concept of the software and launched its implementation.We present our results on the www.openrouter.net server. Severalother projects have already expressed their interest in the COMBO6 card.From an international point of view, our greatest success this year was our accessionto the 6NET project. Our share in this project consisted particularly inthe development of the IPv6 router mentioned above.The area of Multimedia Transmissions is rather varied and our activities aim invarious directions. We have been developing the routinely used videoconferencetools for MBone and H.323. Considering the fact that the MBone network isstill not generally accessible in a number of locations, we devote our attentionto the development of mirrors, enabling the use of MBone also within a networkwhich does not support group addressing of datagrams.We have developed and maintained a portal for easy control of mirrors. Inorder to provide more information to users, we reconstructed our website devotedto multimedia transmissions at www.cesnet.cz in 2002.We have supported several distributed groups in their videoconference effortsand we try to make use of these examples to present the opportunities offeredby videoconferences. We launched the development of access points of theAccessGrid network, offering subscribers the advantages of videoconferencingservices with maximum quality. Another interesting project is the Internetbroadcasting of Czech Radio, at high quality, which we launched earlier thisyear.Within the MetaCentrum project, we have been developing an environment fordemanding user’s projects. The existing clusters of the MetaCentrum offer over150 Intel Pentium III and IV processors. These services are currently used byapproximately 200 users.In 2002, we launched another extension of the computing capacity, purchasing32 dual-processor stations. Unfortunately, the supply of these stations wasdelayed. This is why the new cluster will not be installed until the beginning of2003. Furthermore, we have developed the software for MetaCentrum, particularlywith respect to task planning and user administration.We have contributed a great deal to the success of an international team thatwon during the SC2002 fair in several categories of the High Performance ComputingChallenge and High Performance Bandwidth Challenge.One of the network applications that has lately reported a significant developmentis IP telephony. The strategic project of Voice Services in CESNET2 includestwo sections: an operational section and a research section. As regardsthe operational activities, we have been further developing the network for IPtelephony which is used by the connected institutions for their standard phoneHigh-speed National Research Network and its New Applications 200213
