Consultancy and engineering services

UIS labour rate per hour3 UIS consultancy charges apply
UIS labour rate per day3 UIS consultancy charges apply

 

Notes

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

2. Serial Ethernet entails extra charges based on the cost of leased circuits from BT or other external telecomms organisations.

3. 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.

These prices apply to University institutions and Colleges, and to Research Council institutions that have an appropriate agreement with the University. Output VAT will be applied to the charges where applicable.


Preliminary 10G CUDN connection charges

Please find below some preliminary prices for the 10G CUDN PoP services announced earlier in 2016. These have been published as a guide to provide some indication of the eventual service charges once they are finalised.

Since the techlink earlier in 2016, the cost of some active equipment components has increased substantially. We would like to minimise the service charges and so we are currently undertaking two areas of work -

  • Arranging a price agreement for our preferred hardware solution.
  • Identifying some alternative hardware to provide cheaper solutions where appropriate.


As this process is not yet complete, the prices listed below are indicative only, and should not be considered as definitive. When the procurement phase is complete, we will have precise figures which we will circulate in due course. Until that time, please use the figures below as an approximate guide.

Network connection (PoP)

A CUDN network connection provides exclusive use of a 1 Gbps CUDN router port, and is suitable for connection of an institution's LAN on which there may be many kinds of traffic. An IP subnet is dedicated to the institutional network: IP traffic between that subnet and another is passed, but traffic not related to the institutional network does not enter it at all, and protocols not supported by the CUDN do not enter the CUDN (but see VLAN supplement below). The same link is used if the institution elects to join the Managed Cluster Service (MCS), or indeed wishes to use the Lapwing service. The connection, up to and including the point-of-presence (PoP) equipment on the institution's premises, is managed by the UIS Network Team. That PoP takes the form of a standardised switch, which has 10 Mbps, 100 Mbps or 1 Gbps ports; subject to prior agreement, the institution will be able to make use of multiple ports on it. The standard 1 Gbps CUDN PoP configuration is detailed here. Filtered Ethernet connections are available on sites directly served by the Granta Backbone Network and, using ntl's LANEX service (no longer available for new connections), other sites close to the centre of Cambridge. The charge covers installation adjacent to the site's GBN node: all additional trunking and fibre cabling incurs extra charges. Alternatively, where connections are made by ntl LANEX, the charge will be the sum of the standard filtered ethernet charge and the ntl LANEX charges.

Network connection (PoP) serial

A serial ethernet connection is the equivalent of a normal Network Connection but is for a site not served by the GBN or by ntl's LANEX. In this case, a circuit is leased from a public telecommunications operator (such as BT or ntl). Serial Ethernet is the functional equivalent of Filtered Ethernet: it connects an institutional IP subnet. Historically, the service has been offered using HDSL bridges but this is now deprecated and higher bandwidth leased circuits are now recommended. The PoP equipment will be the standard equipment used for the 1 Gbps service. The charges will be based on the equipment installed including the shared cost of the CUDN infrastructure. The cost of the leased circuit is not included.

VLAN supplement

Institutions with more than one CUDN Ethernet connection (eg department and annexe or college and hostel) are able to request a Virtual Local Area Network (VLAN) between them, though availability is presently subject to confirmation of technical feasibility in each case. The VLAN gives the effect of protocol-transparent bridging within the CUDN infrastructure, which will carry all traffic between the nodes of the VLAN. Note that this does not amount to support within the CUDN for non-IP traffic: it is equivalent to (and potentially cheaper than) private circuits, and connects only nodes belonging to the same institution. Node-to-node throughput will not necessarily reach the bandwidth of the physical connection.

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.

Network traffic charges

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.
