Network

The FIB computers are connected by a local network that links the School building (B6) to computer room buildings A5 and C6. This network provides access to the UPC network (UPC's computer network). This UPC computer network, which includes that of the FIB, forms part of the Internet.

The connection between the B6 Building and the main UPC network is via an ATM switch (a FORE) "ForeRunner LE155" over a 155 Mbps ATM link. You can monitor the traffic on this connection.

During the summer of 2000, the FIB network was completely renewed and new CISCO Systems computers were bought. Specifically, the old router and all the network access equipment (hubs, switches, terminal servers, etc.) were replaced by two high performance level 3 switches and thirteen 10/100 Ethernet switches, keeping only the aforementioned ATM switch for access to the UPC network.

The benefits of this update are:

We have a faster network:

The backbone of the network has gone from 155 Mbps ATM to Gigabit Ethernet (1 Gbps). The wide range of different computers used to access the network (shared 10 Mbps network nodes) have been substituted for switched ports that can be configured as 10 or 100 Mbps.

We have a more reliable network:

One of the weak points in the old FIB network was the fact there was only one router. Now there are two level 3 switches carrying out this task that, as well as balancing the routing load, provide the possibility of one router taking control of the whole network if the other should fail.

We have a safer network:

Having a network that operates under switching in its totality means that computers accessing the network without authorisation are detected, and the port they are connected to can be blocked.

B6 Building network

The backbone of the computer network is in the School of Informatics building. There are twoCatalyst 4908G-L3 routers, and four Catalyst 3548XL switches, which provide access to the FIB administration and service computers, plus the Catalyst2924XL, which bridges our Gigabit backbone and the UPC ATM backbone.

Also, all the servers for both teaching and administration activities are in this building:

UNIX servers

ALABI, ALABA, ALUMBRA, XINO (WWW server for the FIB), ADA, MOONREY, FISSIO, FUSIO, MORGANA (e-mail and student webpage server), etc.

NT machines

The CATSIS server allows students to work on the SQL Server.

Two Novell/Netware servers

ICARO and MORFEUS serve the FIB administration PCs.

Other machines

PCs, work stations, etc. that the FIB staff uses.

A5 Building computer room network

The network in basement 1 of the A5 Building consists of four Catalyst 3548XL switches. These offer 192 switched Ethernet ports, configurable to 10 or 100 Mbps, half-duplex or full-duplex, with a switching speed of up to 200 Mbps.

These switches form a Gigabit Ethernet stack and are connected to the B6 Building network through two fibre-optic cable links over Gigabit Ethernet. This double link allows the distribution of traffic and offers a line that can tolerate the failure of one of the cables.

The following machines are connected to this network:
    X-Terminals
    Graphical terminals Sun Ray
    PCs in the computer rooms and Operations Service
    Printers
 

C6 Building computer room network

The network in basement 3 of the C6 Building consists of four Catalyst 3548XL switches. These offer 192 switched Ethernet ports, configurable to 10 or 100 Mbps, half-duplex or full-duplex, with a switching speed of up to 200 Mbps.

These switches form a Gigabit Ethernet stack and are connected to the B6 Building network through two fibre-optic cable links over Gigabit Ethernet. This double link allows the distribution of traffic and offers a line that can tolerate the failure of one of the cables.

The following machines are connected to this network:
    Graphical terminals Sun Ray
    PCs in the computer rooms and Operations Service
    Printers
