Fault Tolerant Scheduling on Control Area Network (CAN)
Publication Type:
Conference/Workshop Paper
Venue:
IEEE International Workshop on Object/component/service-oriented Real-time Networked Ultra-dependable Systems
Abstract
Dependable communications is becoming a critical factor
due to the pervasive usage of networked embedded systems
that increasingly interact with human lives in one way
or the other in many real-time applications. Though many
smaller systems are providing dependable services employing
uniprocesssor solutions, stringent fault containment
strategies etc., these practices are fast becoming inadequate
due to the prominence of COTS in hardware and component
based development(CBD) in software as well as the
increased focus on building system of systems. Hence the
repertoire of design paradigms, methods and tools available
to the developers of distributed real-time systems needs
to be enhanced in multiple directions and dimensions.
In future scenarios, potentially a network needs to cater
to messages of multiple criticality levels (and hence varied
redundancy requirements) and scheduling them in a fault
tolerant manner becomes an important research issue. We
address this problem in the context of Controller Area Network
(CAN), which is widely used in automotive and automation
domains, and describe a methodology which enables
the provision of appropriate scheduling guarantees.
The proposed approach involves definition of fault-tolerant
windows of execution for critical messages and the derivation
of message priorities based on earliest deadline first
(EDF).
