Servers And Workstations
The current communications infrastructure at YerPhI has been developed beginning
from 1994-1995 and mainly based on 10Mbps Ethernet technology. Later
development 2001-2002 by using DESY supported old 10Mbps switches mainly
concerned with sufficient enlargement, but actually information backbone itself and
its topology remain unchanged. Last development was 2005- 2006 NATO
Networking infrastructure project.
In the framework of that project 4-wire Fiber optic cable are installed between 6
buildings of Yerphi.
The new layer-II switches (one per building) were installed. User level network still
manly based on 10 MB Hubs and hub-segmented huge network does not allow
securely isolate one segment from other one and using VLANs. Even segmentation
via routers does not solve the problem inside the segments themselves.
For end users in YerPhI there used Intel based Workstations with Linux and
Windows platforms.
All computing facilities are included in YerPhl's Local Area Network. YerPhI LAN
includes 10 buildings, covering big enough area. Practically all types of services
with TCP/IP protocol stack are available for end users.
In total YerPhI computer network consists of over 400 workstations. They are
located in 10 buildings
At Yerphi and Aragats ,Nor-Hamberd Stations (see Site Diagram).
YerPhI Bandwidth Allocation and Firewall Policies
YerPhI LAN has two outbound channels 12 Mbps through Web LLC and 6 Mbps through National
Academy of Science of Armenia. YerPhI is a RIPE member (AS12304) and owns 8xC class IP address
ranges.
IP Space is divided in 3 groups.
IP Group “Grid” members and policies:
GRID Cluster
