All the CEINGE areas are provided with wired and wireless internet connectivity, allowing internet access to all laboratories, service areas and offices; the wired connectivity is distributed by using Gbit fibers from one central area of the building to all peripheral areas and can be summarized as follow:

• Central network;
• Peripheral network;
• External connectivity;
• Client connectivity;
• Wirless network.

• Central network: One central network node provides connection to the peripheral nodes and connectivity to the internet; it is located in the server room where all the computing servers can connect redundantly to it by using ethernet connectivity up to 2 Gbit/s.
• Peripheral network: 12 network nodes are distributed homogeneously in the building and provides ethernet connection to the clients; each network node can be configured to offer different virtual LAN, allowing client grouping and low level isolation between groups of computers, for security and network manageability.

La rete interna e’ basata su una tipica architettura a stella ed e’ composta da:

• 1 nodo centrale, sul quale convergono I servers e I nodi periferici. Il nodo garantisce connessione ridondante a 1 o 2 Gb/s a tutti i server.
• 12 nodi periferici corrispondenti ad altrettante aree. I nodi garantiscono la connessione delle macchine client alla rete e sono a loro volta connessi in tecnologia ethernet 1Gb/s al nodo centrale.VLAN
• Connessione in fibra con il nodo della rete di Ateneo. Il nodo e’ situato nella vicina Facolta’ di Medicina e garantisce anche la connessione alla rete della ricerca GARR in link 1Gb/s in fibra.
• I client. I client periferici sono collocati nei laboratori e nelle altre aree dell’Istituto e comprendono macchine con sistema operativo Windows, Mac OS o Linux
• Wireless

Network services

Almost all network services work transparently to the users... Sebbene questi servizi non siano direttamente utilizzati dagli utenti, sono tuttavia necessari a garantire il corretto funzionamento di tutto il sistema.

Sono inclusi:

Servizi di base per la funzionalita' della rete e di altri servizi

DNS

text

DHCP

text

Firewall

text

NAT

text

VPN

text

LDAP 

Il servizio centralizzato di gestione utenti per l'autenticazione e' stato realizzato per mezzo del sistema LDAP ed e’ stata garantita la sua integrazione con il database degli utenti ed e' utilizzato da vari server, in modo da permettere all'utente di accedere a tutti i servizi per mezzo di un singolo account personale.

Servizi di amministrazione di rete e monitoraggio

Amministrazione remota delle macchine

text

Controllo di consistenza dei sistemi

text

Monitoraggio della rete e dei servizi

text

E’ garantito il controllo continuo di tutte le funzionalita’

text

Funzionalita’ delle apparecchiature di rete

text

Raggiungibilita’ delle varie aree

text

Disponibilita’ dei vari servizi
