Data system overview

The data system architecture design philosophy for 'SFOC', which is a large-scale distributed system for support of current and future space missions at the JPL, stresses 'design for change' standardization that will permit software-reuse, periodic hardware-changeout, and network-configuration evolution. Multimission capabilities are supported through a buildup of the baseline system with a minimum of special-purpose adaptations. SFOC can accommodate multiple users representing multiple disciplines, and is capable of furnishing near-real time and nonrealtime support to end-users for downlink (telemetry) and uplink (command) functions.
