This part of ISO/IEC 14165 defines the FC-AE-RDMA Upper Level Protocol. FC-AE-RDMA follows the SCSI-3 FCP standard in its definition of the services necessary to support low latency, low overhead communication between elements of a mission-critical avionics system. This part of ISO/IEC 14165 is intended to serve as an implementation guide to maximize the likelihood of interoperability between conforming implementations. This technical report Prohibits or Requires features that are optional and Prohibits the use of some non-optional features that are referenced in some standards (see Clause 2). In addition, this technical report simplifies implementations and their associated documentation, testing and support requirements. This technical report does not define internal characteristics of conformant implementations. Nonetheless, it incorporates features from the standards listed in Clause 2.
