The reliability of our connection to the GÉANT network isincreased substantially and costs for this connection are minimized as well.138 High-speed National Research Network and its New Applications 2002
Figure 10.2: Utilization of individual GÉANT network nodes10.2 CESNET Involvement in theGÉANT ProjectBesides the setting up and operation of the GÉANT network, the GÉANT projectinvolves research in the area of information and communication technologies aswell. To maintain this research, workgroups entitled TF-NGN (Task Force – NextGenaration Network) have been established. Research teams CESNET activelyparticipate in the following workgroups:10.2.1 TF-LBEThe TF-LBE group (Less than Best Effort Services) deals with the LBE serviceimplementation issues. By making use of this service, it is possible to send datato the network at maximum speed without degrading the connection quality ofHigh-speed National Research Network and its New Applications 2002139
