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

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.
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

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 endusers
Also available
IPv6
IPv4/IPv6 multicast
Current efforts:
Recognizing and finding multicast sources in
AMRES (ie digital National TV channel)

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.
Academic Network of Serbia

University Hospital – eHospital and NREN
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
Institute of Physics Belgrade – IT activity
Grid Activities:
SCL, http://www.scl.rs/
Hosts the largest Grid site
in SEE (1000 CPUs and 50 TB)
Provides regional core services
Coordinates regional Grid operations
Coordinates AEGIS (Academic and
Educational Grid Initiative of Serbia)

Current efforts/Future plans
EduROAM
joined the eduroam European confederation
Being part of eduroam allows users to access a
wireless network at a visited institution simply
using the same credentials from their home
institution
AAI infrastructure
Lack of the driving application
E-learning efforts
New challenges toward NMS
