Information dominance has always been an important factor in defense and military operations throughout history. The DoD has recently accelerated research, development, and deployment of Network-Centric Warfare (NCW) systems to create new types of information links for competitive advantage. High-speed Network Nodes, which provide packet switching and network interfaces, and the links between these Nodes form the foundation of the network system. The many potential advantages of NCW systems, such as decreased time, decreased costs, and improved performance, are well-documented. However, significant technical barriers exist to network deployment in many DoD applications including:
To date, the majority of Internet build-out has been "office-centric". Commercial network switches are generally 19-inch wide rack-mount boxes with 120VAC power cords, designed for office-space environments. Network interface cards (NICs) are generally PCI or VME-based form factors, for use in high-power PCs and workstations. In contrast, the majority of potential DoD NCW applications require compact, rugged, low-power Network Nodes with high-bandwidth capabilities such as: Network Nodes on
The SAKITM Network Node provides a compact, low-power, high-speed ATM-SONET Node for rugged environments. The SAKI Network Node provides both network-switching and network-interface functions for applications such as sensor networks and mobile networks. The node is both modular and adaptable, enabling a wide range of high-performance, low-latency network infrastructure applications. |
The SAKI Network Node technology was originally developed for sensor network applications including (1) Navy surveillance sensor networks, (2) Navy towed array sonar sensor networks, (3) Commercial seismic sensor networks, (4) Navy shipboard networks and ship/submarine monitoring , and (5) Navy measurement range networks. The SAKI Network Node technology is now in Phase III of the SBIR program and is being widely deployed with thousand of channels delivered to numerous DoD and commercial customers. Key government agencies which can further benefit from the technology include:

Traditional Network Nodes have typically fallen into one of three categories:
SAKI is the first low-power, miniature ATM-SONET Node technology to be made available for general commercial and military use. Because of the extensive use of open-standard interfaces and COTS components, high-speed (155 Mbit/s) SAKI Network Nodes can be manufactured for less than $1K per Node in quantity. |
The SAKI Network Node is the world’s smallest and lowest power ATM-SONET Node. It provides an add/drop data bus, ATM-SONET network interface, and ATM virtual channel switching for space- and power-constrained networks such as sensor networks, robotic networks, and shipboard networks. Features

Limited-feature Phase I SAKI Nodes (2.3 Watts per Node) have been available for 2 years and are currently in operation in numerous Navy and commercial sensor network systems. The next-generation SAKI Network Node is in Phase II prototype testing and is transitioning to Phase III product release. Planning Systems Inc. is currently accepting orders for the Phase III Nodes and is offering licensing opportunities for the SAKI technology. The Phase III SAKI Network Node is scheduled for release in Q2-2001. The SAKI network-programmable, modular architecture allows the Node design to be adapted to a wide variety of network applications. Planning Systems Inc. encourages potential clients to contact us regarding product definition and features to accommodate emerging programs. |
