This document defines the requirements for routing protocols through a MIL-STD-1760 carriage store. It includes Miniature Mission Store Interfaces. This document begins with outlines of current carriage configurations, continues by describing typical emerging hierarchical topologies and why it is that the existing standards are inadequate. Different protocols are then discussed, with the document concluding with a set of recommended requirements and metrics for routing protocols to be included in MIL-STD-1760. This document complies with the OSI Basic Reference Model (ITU-T Rec. X.200 | ISO/IEC 7498-1) in that it describes operations and mechanisms that are assignable to layers as specified in the OSI Basic Reference Model. This document also complies with the Generic Aircraft-Store Interface Framework (GASIF), SAE AIR5532.
