Future Core Network
VEGA has assisted the UK MOD model with its ‘as-is’
communications systems enterprise. This was an essential first step
in planning a cost-effective, efficient migration to a Future Core
Network.
The Challenge
As part of the Global Communications Network
(GCN) and the Network Enabled Capability (NEC) initiatives, the
Defence Equipment and Support (DE&S) Global Communications
Systems IPT are assessing the potential different technical and
procurement mechanisms for providing replacements to the existing
systems. One option is to contract for an end-to-end service that
encompasses all the systems including DII and satellite
communications. The Global Communications System IPT recognised the
need to use Enterprise Architecture (EA) methods to model the
‘as-is’ communications enterprise so that a recognised,
understandable baseline was established.
How VEGA is helping
VEGA was commissioned to produce an
Architectural Boundary Study. VEGA consultants created and
maintained a ‘system of systems’ model that covered the ‘as-is’ MOD
communications domain.
In producing the study, VEGA modelled the
MoDAF strategic, acquisition, operation and system views of the
existing communications systems (SKYNET 5, DFTS, DHFCS, NEST,
SCOT5, PSC504, PSC506 etc) and specifically the interfaces and
interoperability of those systems. This model illustrated the
information exchanges and interconnections between these existing
systems and other systems and applications.
The model was used to illustrate different
boundaries of the Future Core Network (FCN) with the aim of finding
a boundary that will minimise the interface risks technically,
operationally and programmatically.
Value being delivered
The work carried out by VEGA allowed the
customer to have a clear understanding of the current (as-is)
communications systems enterprise. It did this by providing visual
representations (MoDAF views) of the domain. This established a
baseline from which to plan a cost-effective, efficient migration
to a future core network.
By fully understanding the baseline system of
systems, the customer could identify the core requirements of the
Future Core Network and anticipate, assess and mitigate the likely
risks in establishing and moving to that new network.
The EA model helped the customer identify
cost-effective, efficient solutions for the future network by
allowing solution options and alternative processes to be compared
to identify the most effective approach to either minimise costs,
risks or maximise capability.
