Comunications

   

The UOC network is a Campus network with star topology.

From the point of view of communications, for both data and voice we differentiate by volume between the four centres sited in Barcelona and the fourteen support centres that the University has at present. Most of the staff, both administration and teaching, are concentrated at the Barcelona buildings.

The Barcelona centres (Av. Tibidabo, 22@, IN3 and Rambla) are connected to the intranet with circuits that go from 400 Mbps to 1 Gbps with two different operators, Telefónica on the one hand with the Macrolan solution and CESCA on the other. The traffic is distributed between the two operators by volume and type. A single operator is able to switch and take all the traffic in the event of an incident.

With fewer users and other volumes, the support centres are connected to the internal network by vpn-ip, benefiting from the same resources as the other networks. These centres are no exception and also have redundant links, which allow us to distribute the load or take it all in case of need.

Although the University works primarily with structured cabling, it has two Wi-fi networks both for UOC users and external users, one of them public and the other for users whose origin organisation is also part of the Eduroam service.

As regards internet communications, the UOC is connected by two pairs of geographically distant and redundant GTWs, via Telefónica and Cesca, registered as autonomous system (AS) using BGP-4.

With regard to telephony, communications between centres is done by IP trunking through data links and to the public network through ISDN links, with the capacity of these varying according to the centre. Communications to/from mobiles is through PRIs (Primary Rate Interfaces, a telecommunications standard used in the Integrated Services Digital Network) by Telefónica Móviles.
