Automated Digital Network System (ADNS)
The Automated Digital Network System (ADNS) is the backbone
to JMCOMS. ADNS uses off the shelf protocols, processors and routers to
create a robust and flexible networking environment. Internet Protocols
(IP), Asynchronous Transfer Mode (ATM) and other products are being adopted
or adapted from the commercial telecommunications world. Interfaces to
all RF media from HF to EHF provides the total throughput and access needed.
At the same time, networking techniques make efficient use of all available
channels.
ADNS provides the following improvements:
-
Furnishes autonomous, digital, interoperable, joint
and secure LAN/WAN management and control for RF assets on demand to Navy
deployed personnel aboard ships and at shore sites
-
Ensures worldwide communications connectivity via
the RF assets included in DMR and ITP
-
Automates all communications systems-replaces several
unique subnetworks with a single integrated network hub
-
Provides Integrated Network Management (INM) which
resolves problems caused by overloading or underutilization of existing
communications circuits, yielding a 4X increase in multispectrum throughput
efficiency over legacy systems
-
Applies NDI COTS/GOTS router, switching and packet
data technologies enabling reduced life cycle costs
ADNS is composed of three functional elements: Integrated
Network Management (INM), Routing and Switching (R&S), and Channel
Access Protocols (CAP). The INM provides the flexibility to adapt communications
to available assets and mission priorities. It uses COTS software and resides
on TAC-4 workstations. The R&S subsystem provides the interface to
users, and performs routing and switching of user data to available transmission
circuits. The objective R&S subsystem includes a COTS IP router, a
suite of common packet routing protocols and COTS Integrated Services Digital
Network (ISDN) and ATM switches. CAP equipment manages data exchange over
JMCOMS circuits and networks, monitors network quality of service, and
reports loading and error conditions to the INM.
