What is ADNS?
• ADNS is an integral part of a complex
communications system that provides an
automated pathway for information to travel
along any available transit link.
• Provides for optimal use of bandwidth
assigned by the system to:
–
–
–
–
–
UNCLAS
SECRET
SCI
Coalition
Other afloat networks and their shore counterparts
ADNS “Vision”
• Provide assured gateway availability for
critical paths/applications
• Guarantee 100% end-to-end delivery of
selected voice, video, and data
• Provide restore capabilities
• Increase information transfer efficiency
• Reduce manning and operation costs
• Provide joint interoperability

ADNS Increment I
Capabilities
• Consolidated WAN access for
Multi-security level networks (via
NES, TACLANE)
• Link preference: DSCS, CWSP,
EHF, IMS
• Hot-standby Link Failover
• Bandwidth Reservation per security
level
• Ship-to-Ship LOS links w/IP (VTC
over DWTS)
• Ship-to-Shore MAGTF support
• Pier-side network access
Constraints
•
IP traffic uses only one RF
link even if more are
connected
•
Best Effort delivery (i.e. no
application has priority)
•
Fixed bandwidth allocation to
each enclave
Justification for Change
• Increased demand requires more efficient
use of RF bandwidth
• Need to prioritize network traffic
• Must be able to monitor and control
network traffic based on applications
Inc II Capabilities
• Increment II = Inc I plus:
– Traffic distribution over multiple links
– Adjustable bandwidth guarantees
– Application prioritization
– Improved link monitoring tools
– Application monitoring
Components
• Integrated Network Management (INM)
– LQoSMAN
• Routing and Switching
– Cisco router

Quality of Service (QoS)
• Control over resources
• More efficient use of network resources.
• Tailored Services
– Grades of service differentiation to the customers.
• Coexistence of mission-critical applications
– Bandwidth and minimum delays required by timesensitive multimedia and voice applications are
available, and that other applications using the link
get their fair service without interfering with missioncritical traffic.
• Foundation for a fully integrated network in the
future

• Application Monitoring
and Blocking
– PacketShaper Overview
• Traffic and Bandwidth Management system that
delivers predictable efficient performance for
applications running over the WAN
• 7 Layer classification, analysis, control, and
reporting capabilities.
– Enables managers to keep critical traffic moving at an
acceptable pace through bottlenecks and prevents any
single type of traffic from monopolizing the link.

before getting to the really high-speed shore infrastructure.
