And the Strategic Shortcomings
A Technical Design Authority for the Network
The Network Technical Design Authority (TDA) is responsible for establishing
and maintaining the overall technical architecture of the Core Network so
that it might be developed and operated in a manner which is consistent with
the strategic goals of the STFC, and remains fit for purpose in the light of the
evolving demands of its user base.
The TDA reports to the IT Operations Board (ITOB) and to the Information
Management & Technology Strategy and Oversight Committee (IMTSOC).

FY2011-12 (£350k)
1. Janet connectivity increased to resilient 30Gb
2. RAL site geographically resilient
3. New external core routers operating in a resilient
configuration using a 80Gb ring operational June 2012
4. “Big” Data centric “clouds” being migrated to the new
infrastructure: LHC Tier 2 migrated, JASIM/CEMS in
advanced stages, British Atmospheric Data Centre and LHC
Tier 1 started

FY2012/13 (£200k)
1. RAL Firewall re-procurement to provide 40Gb throughput in
HA configuration
2. Fortinet Fortigate-3240C firewall selected and procured
3. Implementation planning underway with target operational
service in summer 2013

Implementing a New Network
FY2013/14 (£130k)
1. Focus: internal RAL network: to dis-aggregate complex
configurations; to provide a simple IP routed environment
2. Review (and replace) Nortel stacked switches and routers to
provide appropriate, i.e. modern, technology to level
performance needs and based on reliability assessment
3. Introduce better instrumentation through the network
