Table 2 Techniques [8] selected for the development of software architecture
From: Development and validation of a safe communication protocol compliant to railway standards
Technique | Description | Implementation |
|---|---|---|
Structured methodology | Use of precise and intuitive notation to promote the quality of software development by focusing attention on the early parts of the lifecycle | ODP reference model [17] |
Modeling | Use of precise and field-specific graphical formalisms to provide a complete description of the system and its parts | Sequence, state-transition, and structure diagrams |
Fully defined interfaces | Complete definition of both internal and external interfaces of each SW module | Detailed description of interfaces for each SW module |
Defensive programming | Detect anomalous control flow, data flow, or data values | Acceptance/credibility checks, control flow monitoring |
Error detecting codes | Detect errors in sensitive information by, e.g., Hamming, cyclic, or polynomial codes | Cyclic redundancy code |
