Problem-1: Scalability in Operational Tests
• OTC must establish that the network (or system) under test can
operate in operationally relevant deployments based on
specified requirements at scale.
• It is often hard, if not impossible, for OTC to have access to the
needed number of physical radios to achieve the desired scale
• “How can we make 30 GMR live radios believe that they are a
part of a 100 radio network?”

Problem-2: Realistic Network Loading
•
To stimulate a live NSUT (Network
System Under Test) with‘large-scale’
network traffic profile, M&S based
tools are used by T&E community
•
•
•
OneSAF C2 Adapter, C3 Driver,
ExCIS generate C2/SA messages in
the live message form as if they are
being generated by additional units
Messages injected directly into the
live network assuming perfect
comms between these additional
units and live injection point
Realistically, if these messages were
to come over a live network of
forces, fraction of these messages
would be lost or suffer delays due to
the wireless medium, unit mobility,
and the radio network characteristics
•
Traffic Injection into NUT assuming
perfect communications
Perfect Communication based
injection of these messages takes
away the realistic nature of the
operational test.
Traffic Injection reflecting impact of
dynamic network connectivity, link
bandwidth and channel quality
Units Moving out of radio range
BCNIS Overview
• OTC’s Battle Command & Network Integration and Simulation
(BCNIS) is a test suite that augments a live tactical network with
an ‘LVC capable’ constructive tactical network that consists of a
seamlessly integrated set of component products that together
provide the following set of functionalities in a LVC context:
•
•
•
•
Constructive Force Representation
Constructive Network Representation in network simulation
Tactical C2/SA Applications
Interface to live network for LVC operation
• Achieves Realistic Network Loading by interfacing constructive
radios with M&S based Tactical Message generators and
providing realistic communication effects to these messages
before being injected into the live NUT
• Network Simulation employs high fidelity models of radios, wireless
channel effects and terrain
• Achieves Scalability for OT using Live Virtual Constructive
representation to increase the size of the NUT

BCNIS Components: Role Player Work Station
• Surrogate for the live Command & Control /Situational
Awareness applications that run on the live side
• C2 and SA messages from RPWS are injected into the
constructive radio that it is mapped to run on

BCNIS Components: OneSAF C2 Adapter
• Generates actual SA messages for the semi automated units in
OneSAF
• These messages are injected into the corresponding
constructive radios in JNE for realistic communication effects

BCNIS Components: XPRT Solution’s HITL module
• Injects control and data traffic (which includes actual C2/SA
messages) from constructive into live network and vice versa
• Provides instrumentation of traffic between live and
constructive networks

BCNIS Accomplishments in SIT Part 2
•
Objectives were to verify LVC operation with live radios, realistic
network loading of the live NUT and demonstrate robustness of BCNIS
•
Observations from SIT Part 2:
•
Full OSPF convergence for all live and constructive radios
•
Multicast traffic from live radios received by constructive radios
•
Traffic originating from constructive radios reached live, seen in data
reduction reports
• Unicast UDP TGEN originating from virtual node
• Multicast TGEN originating from virtual node
• JVMF K5.01 SA traffic originating from C2 Adapter and passing through
constructive network to live with accurate communication effects
• SA periodic updates when virtual units are stationary and dynamic updates when
units moved in OneSAF
• Several runs with BCNIS injecting realistic traffic continuously for
3 hours during SIT Part 2

SINCGARS and EPLRS
– Real-time Data Collection and Instrumentation of the
constructive network
– Root cause analysis to understand constructive network
behavior
– Real-time Visualization of the constructive network status
– Integration with tactical applications of interest to the T&E
community and programs such as JCR, BFT-II
