Network Protocol Stack
Multi-Layer Network Protocol Software Suite
Software protocol stack providing reliable data communication services to all applications
Purpose
Software protocol stack providing reliable data communication services to all applications
Context
Child of L2-CDH-BUS
Principles
- ▸CCSDS packet telemetry and telecommand standards for space data protocols
- ▸Reliable data delivery protocol handles packet loss from radiation-induced errors
- ▸Time synchronization protocol (PTP/IEEE 1588) maintains network-wide time alignment
- ▸Protocol stack is hardware-independent enabling migration to future hardware
Typical implementations
- ▸CCSDS Space Packet Protocol (SPP) for telemetry and commands
- ▸CCSDS File Delivery Protocol (CFDP) for reliable file transfer
- ▸NASA cFS Software Bus for publish-subscribe messaging
Lunar considerations
- ▸Protocol must handle higher-than-normal error rates from radiation environment
- ▸Time synchronization critical for coordinating distributed autonomous operations
- ▸Protocol evolution must maintain backward compatibility over 100-year mission
