Brno University of Technology
• Faculties: El. Engineering and CS, Mechanical Eng., Civil
Engineering, Architecture, Business and Management,
Chemistry, Fine Arts
• 12 000 students
• Institutes:
– Computing and Informations Centre:
• metropolitan network (with cooperation of Masaryk
University)
• supercomputer centre
– Centre for Distance Education

• Location: 16 campuses round the city
• ~ 5 000 computers
Project of FEECS backbone
•
•
•
•
•
•
•
grant in 1998 (Ministry of Education)
about 40000$
4 distant large faculty campuses
departments scattered through buildings
no commercial routers (PCs + BSD)
no switches (almost, 2 Catalysts 3000)
high demands
Expected solution
•
•
•
•
Campus centre - Layer 3 switch (1998!)
Building centre - Layer 2 switch
Proposal (1997) - Catalyst 5000/2900
Connection - n x 100 Mb/s (proposal)
1 Gb/s (solution)
• Choice: Cisco, Bay Networks/Nortel,
3Com, Cabletron, Extreme Networks
Why Summit 48?
• Architecture (both HW&SW)
• Common for Layer2 and 3 switch
• Range of products based on the same
chipset and firmware (Summit 1)
• Relatively long-time on market (4/1997)
• Good tests results
• High port density
• Exceptional performance/price
• No distributor in Central Europe
Project success

University Backbone
• Part of Metropolitan Network
– common cables, dedicated fibers
• Ethernet 10 Mb/s (1992)
• ATM 155 Mb/s started at 1995 (no other
technology available)
• 1999 - no further development of ATM,
transition to Gigabit Ethernet:
– single technology for LAN&MAN
– integrated routing
– simplicity, capacity, price
– QoS not really used in MAN
