LOSTUD – PoP example (1.part) LOSTUD Several institutions share the same building, even a equipment in Floor Distributors Scope of responsibilities (Extended) Lack of ports and IP addresses Map user (username) to MAC address NMS tools is essential End users requires Stable Connection, Mail handling, Web browsing, KOBSON service Akademska mreža Srbije www.amres.ac.yu

National Library of Serbia – KOBSON Access to 35 000 journals http://nainfo.nb.rs/kobson.82.html Serbian library consortium for unified procurement of scientific journals. National Library of Serbia is represenatative The main objectives of the association: Optimized acquisition of foreign scientific information, transition from paper to electronic editions, promotion of national scientific publishing. According to UNESCO on access to scientific literature, Serbia is a leader in the region. Akademska mreža Srbije www.amres.ac.yu

KOBSON service Access to the KoBSON service is provided for all computers that are connected to the Internet through the AMRES. It is necessary in the internet browser to set the appropriate proxy server of the University. Important monitoring of and log process on proxy server First server we started to monitor Good search engine tool through log files ~200Mbps/30Mbps Akademska mreža Srbije www.amres.ac.yu

LOSTUD - PoP exmple (2. part) AMRES has connected to IPv6 backbone via its link towards Hungarnet Finished deploying IPv6 and multicast service trough AMRES internal backbone and toward end- users Also available IPv6 IPv4/IPv6 multicast Current efforts: Recognizing and finding multicast sources in AMRES (ie digital National TV channel) Akademska mreža Srbije www.amres.ac.yu
11
Academic Network of Serbia www.amres.ac.rs IPv4/IPv6 multicast AMRES has connected to IPv4/IPv6 multicast backbone via its link towards Hungarnet We are receiving many IPv4 multicast sources from other Europe NRENs and some commercial multicast sources Problem: currently there is no active IPv6 multicast sources among all Europe’s NREN The only IPv6 multicast group FF1E::1:F00D:BEAC is used for testing purposes Every NREN can be source to or receiver from this test multicast group. In this way IPv6 connectivity can be tested and monitored.

University Hospital – eHospital and NREN Akademska mreža Srbije www.amres.ac.yu Internal telephony system is VoIP based Computationally intensive operations in segmentation and analysis of 3D datasets Telemedicine – remote access to patient data and videoconferencing The UChHIS: centralized storage and thin clients Role based Web access to electronic patient records (EPR) is enabled Scheduling system of UChHIS PACS (Picture Archiving and Communication System) system integrating DICOM imaging devices and workstations
