Although this doesn't provide load balancing or solve the problem that ADNS Inc IIA ships experience when given two DSCS leases for IP services, it does provide a means to use the two DSCS leases independently in a cross-connection configuration, or use a combined DSCS and CBSP lease to more effectively manage bandwidth.
Unfortunately for Enterprise and other ADNS Inc IIA ships, dynamic bandwidth allocation across multiple paths (load balancing) is not possible because ADNS-J was not engineered to support load balancing in its current configuration.
By cross-connecting incoming DSCS and CBSP connections prior to transmission through the ADNS router (see Figure 1) and configuring the router at the servicing NOC, ships can experience upward of 100 percent or more in bandwidth increase or rate of data transfer, especially if they can negotiate a single DSCS lease at a higher bandwidth, instead of two leases at lower data rates.
It is important to note that ADNS Inc IIA ships are not capable of processing two DSCS leases simultaneously, thereby sharing the aggregate bandwidth.
With their initiative, a little shore-side configuration help from NCTAMS LANT, and some creative satellite resourcing from Second Fleet's fleet resources department, the cross-connect concept quickly turned into a standard operating procedure on the East Coast in late 2008 and paved the way for how ADNS Inc IIA ships, like USS Enterprise, can more efficiently manage bandwidth.
The Automated Digital Network System voice team is meeting DISA's requirements by adapting legacy voice circuits for transport using IP-based technologies to both increase bandwidth efficiency and consolidate naval communication pathways across the ADNS network links.
The ADNS voice team introduced the SCIP-IWF as the technological solution capable of coupling legacy telephony products, such as secure terminal equipment and various shipboard telephone switches, to modernized networks capable of servicing a greater number of concurrent calls with more features and at reduced costs in terms of connectivity overhead requirements.
While ADNS transport is a critical element of voice communications modernization, it is complemented by DISA's unified capability requirements, which provide a series of integrated and complementary technical standards and products necessary to meet future Defense Department communications operational and security requirements.
