Compression, Confidentiality & Routing Architectures for Satellite Data

The goal of this effort is to investigate router architecture to seamlessly unite a terrestrial network to a network of satellites. This proposal generates a specification (Phase 1) and test-bed (Phase 2) to address these NASA needs for sensor data transmission:? Data Compression Techniques ? Buffer Management Optimization? Network Architectures? Provide a Terrestrial-based Test Bed Architecture for Concept Verification.Below is our program effort summary.PHASE 1:1. Define a protocol stack for the network including encryption. This investigation uses existing protocols, such as TCP/IP and PPP, as a basis and examines the impact of one-way communications paths upon these architectures. In addition, we determine the optimal placement of encryption into the stack for data confidentiality.2. Target a hardware platform for these protocols. Determine and list the criteria for hardware selection and provide a hardware recommendation.3. List known techniques. List available compression, buffer management and encryption techniques and determine target platform performance.4. Optimize throughput. Sort the list above according to the estimated target platform performance for maximum throughput.5. Generate a specification. Use the results from 1-4 for a router specification deliverable.PHASE 2:1. Develop the Test-Bed. Build the terrestrial test-bed to the specification.
