ISO 20217-2015 pdf free.Space data and information transfer systems – Spacecraft onboard interface services – File and packet store services. A tile store is considered to be a tile syseni and the associated storage medium. At the highest level a tile system is a way to organize, store, retrieve, and manage information on a permanent storage medium. File stores manage permanent storage and form an integral part most onboard spacecraft data handling systems. Different types of file systems (and file stores) may be considered: a) Flat file systems. Designed to not have subdirectories. Everything is stored in the rct level 01 the storage media. b) Hierarchical file systems. Designed to organize inforn’iaion in directories in a tree- like structure. Either of these may be used to support the FPSS services and no restriction is imposed on the type of file store. This approach allows complete independence from the technology used to implement the file store. The way in which this mapping is performed is implementation- specific. The FPSS allow for multiple client processes on multiple machines fbr both accessing and updating tiles. Hence updates to the file from one client should not interfere with access and updates from other clients….
