Short Course - Real Time Industrial Networks for Distributed Enbedded Systems

Prof. Dr. Luis Pinho de Almeida - Univ. de Aveiro (Portugal)

Network in distributed Systems (General Concepts)
• Nomenclature, system components
• Messages and transactions of Networks
• Temporal metrics
• Event or time triggered or communication
• Communication Control
• Information (Data) Flow
• "Interoperatibility" e o OSI Model
• Requirements of Real Time Local Network

OSI Model divided in 3 layers
• Physical Layer
• Data Link Layer (focused on medium access)
• Application Layer
• Real Time Message Scheduling

Paradigmatic Protocols
• WorldFIP (Master-slave)
• TTP/C (TDMA)
• CAN (CSMA/BA)
• Ethernet (CSMA/CD)

Network impact over system properties
• Static versus Dynamic Scheduling
• Event Triggered versus Time Triggered communication
• External versus Autonomous Control
• Synchronization Questions
