UIS Network Service Charges

This page contains a summary of most UIS Networks service charges.  For an explanation and detailed information on the individual services please refer to the specific pages. The Managed Network Service page includes detailed costs for that service not included here.

The prices listed here exclude VAT and are typically correct for University institutions.  For Colleges, Research Council and other affiliated external institutions, VAT will be applied to the charges where applicable.

Notes on CUDN Network Connections

A CUDN 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 CUDN routers.  It is owned and managed by UIS Networks 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 CUDN routers.  The two links provide eBGP peerings with the CUDN routers: the institution will need to run a local BGP router to carry the required networks.  The links from the CUDN 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 CUDN network connection is required if the institution wishes to use other UIS services, such as University telephones or wireless services (eduroam, UniOfCam).

CUDN 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, CUDN 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.

UPS & RPS Services

For more critical areas of the network, the UIS can provide power protection to PoPs or edge switches.  Power protection typically consists of two elements:

  • an Uninterruptible Power Support (UPS) is essentially a large battery that continues to provide power, in the event that the primary supply fails: it is typically connected between the mains supply and the primary power input to the switch
  • a Redundant Power Supply (RPS) provides a second power supply to the switch: it is connected between the mains and the switch and will provide power in the event that the UPS fails

UPSs incur a sizeable recurrent charge due to the need to replace the batteries approximately every 3 years.  It is difficult to predict exactly when a battery will fail but, despite automatic testing an error reporting, it has been found these will fail in around this timescale and it is not useful to discover that a UPS battery has failed only when it is required.

 

 

Installation

Recurrent (per year)

UPS — 1000VA with one external battery £1,793 £275
UPS — 1000VA additional battery £518 £118
UPS — 2200VA with one external battery £2,262 £469
UPS — 2200VA additional battery £792 £239

Additional battery packs extend the runtime of the UPS.  The UIS will size the UPS (either 1000VA or 2200VA), based on the power consumption of the attached devices — typically this will be to around 60% of the maximum load supported by the UPS, as runtime drops disproportionally, above this level.

RPSs are provided to protect against a fault with the UPS.  UPSs can fail for a number of reasons and, when they do fail, they tend to do so in a way which results in the power remaining off, even if the mains supply is available.

Installation Recurrent (per year)
RPS (Redundant Power Supply) for single switch £1047 £150
RPS (Redundant Power Supply) support for second switch £399 £57

RPS equipment can vary, depending on the model of switch.  The above pricing is for the typical UIS-supplied edge switch and consists of an additional 1U device which can support up to two switches.

Notes

1. Normal expected cost – may be less or more in exceptional circumstances.

2. Applicable for on-site work not covered by other standard charges.

In addition to the recurrent charges above, a volume-related charge is made to recover the HEFCE-imposed JANET network charge.


Network Traffic Charges

Higher Education Institutions (HEIs) are charged for part of the cost of Janet by the Higher Education Funding Council for England and the other regional HE funding councils. Although, originally, the charge to HEIs was on the basis of their transatlantic traffic, the Joint Information Systems Committee (JISC) decided at its meeting on 28 March 2002 that a formula-based model reflecting institutional size, according to HESA annual statistics, should be used.

The University's Janet connection charge is recovered by quarterly charges based on all incoming traffic from and outgoing traffic to Janet for the previous quarter. The UIS invoices individual Colleges, Schools, and other institutions quarterly in arrears (usually early November, February, May, and August), except that any bill of less than £5 will be carried forward to the next quarter or the end of the financial year. The charge is based on the actual chargeable traffic attributed to the institution during that quarter, scaled so that the total across all institutions is the same as the amount invoiced by Janet(UK), allowing for VAT.

The traffic that is subject to charging is measured by the UIS at the router that connects to Janet.

  • Cambridge Janet traffic accounting data – recent is an index to web pages showing the breakdown of Janet traffic to/from the CUDN by institution, ordered by total traffic, on a daily, quarterly, and annual basis. The page also links to raw data files to enable institutions to perform their own data processing.
  • Individual web pages per institution giving traffic by individual local computer on a daily basis are available via Cambridge Janet traffic information by host to assist system administrators to manage their usage.
