Summary

All of the shipboard existing systems are integrated via two classification networks, NIPRnet and SIPRnet consisting of a primary Mission Equipment System (MES) LAN. Each MES LAN is connected to NAVOCEANO, Stennis Space Center via Inmarsat B or C-Band High Speed Datalink. There are several VLANs, including the Bathy VLAN, POS/MV VLAN, ISS-60 VLAN. ISS-60 (Integrated Survey Software) ties all of these VLANs together and provides a broad-based data acquisition, display and logging system to collect and monitor navigation, hydrographic, oceanographic, bathymetric and other specialized data.

Overview The T-AGS ships are Oceanographic Survey Ships in MSC’s Special Mission Ships Program. These Multipurpose ships perform acoustic, biological, physical and geophysical surveys, providing much of the U.S. military’s information on the ocean environment. These ships use precision acoustic systems that make it possible to continuously chart a broad section of ocean floor. Some T-AGS equipment is similar to those installed on current Military Sealift Command (MSC) ships, and will consists of non-developmental Government Furnished Commercial Off-the-Shelf (COTS) systems that are part of the commercial vessel’s design.

5.13.2 NIPRnet

The Non-classified Internet Protocol (IP) Router Network used to exchange unclassified information, including information subject to controls on distribution, among the private network's users.

5.13.3 Network Attached Storage (NAS)

The network attached storage device on the MES VLAN provides a central logging repository for all of the survey data. Most of the data is distributed to the NAS from ISS-60, though some interface directly over the 1000MB/s LAN Switch and log directly to the NAS. NAS units support NFS for Linux and SAMBA for Windows.

5.13.4 Bathymetry VLAN

The Bathymetry NIPR VLAN is connected through a switch. Its primary function is to pass all of the sonar datagrams to/from ISS-60. This LAN is isolated from the others to prevent data loss due to network collisions. The current sonar systems have multiple interfaces to their internal VLANs, as well as the Bathymetry and MES LANs on the T-AGS 60 class ships. All of these interfaces are over CAT-6 LAN cables.

5.13.5 POS/MV LAN

The POS/MV VLAN is another VLAN connected through a switch. The primary function of this VLAN is to provide high-speed navigation data via the network to ISS-60. This data is available to other systems, but in most cases the navigation data to other systems is provided by ISS-60 (as described in SOW paragraph 5.14). All of these interfaces are over CAT-6 LAN cables.

5.13.6 ISS-60 LAN

The ISS-60 VLAN is a private LAN connected via a switch that provides network communication between the main ISS-60 workstations. No other systems are connected to this LAN. All of these interfaces are over CAT-6 LAN cables.

5.13.8 ISS-60 LAN

The ISS-60 VLAN is a private LAN connected via a switch that provides network communication between the main ISS-60 workstations. No other systems are connected to this LAN. All of these interfaces are over CAT-6 LAN cables.

5.13.9 Network Attached Storage (NAS)

The network attached storage device on the MES VLAN provides a central logging repository for all of the survey data. Most of the data is distributed to the NAS from ISS-60, though some interface directly over the 1000MB/s LAN Switch and log directly to the NAS. NAS units support NFS for Linux and SAMBA for Windows.

5.13.10 Bathymetry VLAN

The Bathymetry NIPR VLAN is connected through a switch. Its primary function is to pass all of the sonar datagrams to/from ISS-60. This LAN is isolated from the others to prevent data loss due to network collisions. The current sonar systems have multiple interfaces to their internal VLANs, as well as the Bathymetry and MES LANs on the T-AGS 60 class ships. All of these interfaces are over CAT-6 LAN cables.

5.13.11 POS/MV VLAN

The POS/MV VLAN is another VLAN connected through a switch. The primary function of this VLAN is to provide high-speed navigation data via the network to ISS-60. This data is available to other systems, but in most cases the navigation data to other systems is provided by ISS-60 (as described in SOW paragraph 5.14).
