Abstract
The fundamental requirement that must be satisfied by the SDI BM/C2 Communication architecture is to provide a transport interface to each of the three principal SDI functions: Surveillance (sensor subsystems), Battle Management (Sensor, Resource and Weapons Battle Management subsystems), and Weapons (launch and interceptor subsystems). This requirement for transparency can be realized through the integration (tight coupling) of two subarchitectures that comprise the overall SDI BM/C2 Communication architecture. Within each node (satellite), a data flow control architecture (DFCA) can be developed from the node's sensor subsystem to its end-users (SBMs) to provide the capability to transmit a very large volume of track file data (these track files do not consist of state vectors) at high throughput rates, in a congestion-free (prevention of deadlock, livelock, and thrashing conditions) manner. The node's DFCA can then be coupled to the inter-node data link network architecture (IDLNA) to form an integrated, disciplined and synchronized communication system with capability of providing a continuous (uninterrupted flow of track file data, at very high speeds, from any sensor subsystem to its corresponding SBMs (SBMs based at the host and stereo-viewing nodes). The DFCA addressed in this report is based upon satisfying the aforementioned requirements and the following mission-performance related conditions: (1) The availability in Real-Time to all end-users (SBMs and RBMs) of target/object track file data; (2) Uninterrupted flow of data from the sensor focal plane to its intended end-users (SBMs and RBMs); (3) A high reliability of communicating consecutive frame cycle track file data to the appropriate SBMs for stereo-processing; (4) Synchronous and asynchronous parallel, simultaneous, transmission of target/object track file data from each sensor's subsystem to their corresponding end-users (SBMs).
