Notes on UDN network connections

A UDN network connection can be provided in one of two main ways:

  • Via a dedicated Point-of-Presence (PoP) network switch, installed at the customer premises and connected by dual (redundant, active-active) 1Gbps or 10Gbps uplinks to two separate UDN routers. It is owned and managed by UIS and provides a number of customer-facing ports, to which they can connect their network equipment.  It provides a suitable connection for an institution's local network.  The service includes the provision of a single data VLAN with IP subnets as required, dedicated to the institutional network; VLANs for services such as the University Wireless Service and University Telephone Network will incur no additional charge.
  • Via a pair of BGP links, to two separate UDN routers.  The two links provide eBGP peerings with the UDN routers: the institution will need to run a local BGP router to carry the required networks.  The links from the UDN routers can be delivered to a single location or two separate locations, to two separate institutional routers - the institution will likely need to rent GBN dark fibre circuits to interconnect them and their institutional network.

A UDN network connection is typically required if the institution wishes to use other UIS services, such as University telephones or wireless services (eduroam, UniOfCam).

UDN network connections are available at locations directly connected by the Granta Backbone Network. The installation charge assumes the PoP switch is located at the site's GBN uplink location point. If additional trunking and fibre cabling is required, this will be included under a separate installation charge.

UPS with the PoP switch

Note that, as of academic year 2017-18, UDN PoP switches no longer come with a UPS as standard.  Institutions wishing to retain the UPS on their PoP switch can do so, but note these will incur an additional charge — this is the 1000VA UPS with a single external battery (currently £275 /year).

The UIS has made these changes as a growing number of institutions no longer require a UPS either due to a local decision, or having a UPS of their own.  The PoP switch will, however, continue to be provided with dual power supplies.
