Assumed System Requirements

Communication.ASR_ErrorHandling

(C++) exceptions shall not be used for error handling. The best way to deal with errors is to try to resolve those component internally. If not possible the caller of the function shall be notified of the error. For (error) returns there is a specific library to be used in S-CORE, it is the score::Result library which is part of the Base Libraries feature.

Communication.ASR_InterProcessCommunication

The platform shall support inter-process communication.

Communication.ASR_IntraProcessCommunication

The platform shall support intra-process communication.

Communication.ASR_ExtensibleExternalCommunication

The platform shall support external communication via well established protocols e.g. Zenoh, DDS, SOME/IP.

Communication.ASR_SafeCommunication

The platform shall support safe communication in terms of ISO 26262. I.e. it shall provide mechanisms to avoid communication errors defined by the ISO 26262.

Communication.ASR_SecureCommunication

The information exchanged between applications shall be protected against unauthorized access and manipulation. The platform shall provide mechanisms to ensure confidentiality, integrity, and authenticity of the exchanged information.

Communication.ASR_SupportForTimeBasedArchitectures

The platform shall support a deterministic, time-based application execution model that triggers logic based on predefined schedules or polling intervals.

Communication.ASR_SupportForDataDrivenArchitecture

The platform shall support an event-driven, high-throughput application architecture where execution is triggered by data changes.

Communication.ASR_SupportForRequestDrivenArchitecture

The platform shall support a request-driven application architecture that processes requests on-demand.

Communication.ASR_ProgrammingLanguagesForApplicationDevelopment

The platform shall support implementation of applications in the following programming languages up to the highest ASIL level as defined in automotive_safety: C++, Rust.

Communication.ASR_TracingOfCommunication

The platform shall support the tracing of communication events for internal and external communication systems.

Communication.ASR_AvailabilityOfCommunicationPartners

The platform shall provide a mechanism to detect the availability of communication partners for internal and external communication systems and provide the required information to communicate with them.

Communication.ASR_StablePublicApi

The platform shall provide a stable API for the communication middleware.
