Library Networks
 Ethernet
for building LANs
 Older networks using 10Base2
(ThinWire) Ethernet
– Coaxial RG-58 cable in bus topology
– All will be converted to 10BaseT in next 2
years
 Newer
networks use 10BaseT
– Category 5 or Category 6 UTP
Network Communications
 10Base2
networks use DEC DEMPR
(Digital Ethernet MultiPort Repeater)
– 10 to 30 stations per Segment
– 8 Segments / DEMPR
 Each
DEMPR connects to a Switched
Ethernet port on a FORE PowerHub
 Each PowerHub connects to campus
backbone via ATM
Network Communications
 10BaseT
Hubs
Networks use HP Ethernet
– SNMP Managed
– Security enhancements such as data
scribbling to non-destination ports
– 10mb/sec shared Ethernet
 Each
hub connects to switched Ethernet
port on PowerHub
 PowerHub connects to ATM network
Network Communications
 Servers
connect directly to switched
Ethernet ports on PowerHubs
– Currently 10mb/sec
– Plan to increase to 100mb/sec
Desktop Computing
 400+
Desktop Computers
– All but 40 Pentium based
 Windows
NT 4.0 operating
environment
 Novell IntranetWare Client
 Novell Application Launcher
 Most applications loaded from servers
Campus Backbone Architecture
 ATM
Backbone
 FORE PowerHubs
 Fiber Optic Network
– Distributed Star Topoloty
– Multiple Fiber Distribution Centers
 Switched
Ethernet in Buildings
 Shared Ethernet for most LANs
