text: There exist many optimal or heuristic priority rules for machine scheduling
problems, which can easily be integrated into single-objective evolutionary algorithms
via mutation operators. However, in the multi-objective case, simultaneously applying
different priorities for different objectives may cause severe disruptions in
the genome and may lead to inferior solutions. In this paper, we combine an existing
mutation operator concept with new insights from detailed observation of the structure
of solutions for multi-objective machine scheduling problems. This allows the
comprehensive integration of priority rules to produce better Pareto-front approximations.
We evaluate the extended operator concept compared to standard swap mutation and
the stand-alone components of our hybrid scheme, which performs best in all evaluated
cases.

text: Inter-datacenter transfers of non-interactive but timely large flows over
a private (managed) network is an important problem faced by many cloud service
providers. The considered flows are non-interactive because they do not explicitly
target the end users. However, most of them must be performed on a timely basis
and are associated with a deadline. We propose to schedule these flows by a centralized
controller, which determines when to transmit each flow and which path to use.
Two scheduling models are presented in this paper. In the first, the controller
also determines the rate of each flow, while in the second bandwidth is assigned
by the network according to the TCP rules. We develop scheduling algorithms for
both models and compare their complexity and performance.

text: In this paper we present an approach for the self reconfiguration of distributed
micro-controllers for increased fault tolerance. Based on a modified distributed
system topology utilizing a time division multiple access (TDMA) protocol, i.e.,
Flex Ray, we present a self-organized distributed coordinator concept which performs
the self-reconfiguration in the case of node failures. We introduce a distributed
coordinator, which utilizes redundant slots in the Flex Ray communication schedule
and combines messages in configured protocol frames and slots to avoid a complete
bus restart. As such, the self-reconfiguration is realized by means of predetermined
information about resulting changes in the communication dependencies and (re-)assignments
determined in the design phase. To retrieve the necessary information, we present
an analytical approach, which determines a combined solution for the initial configuration
and all possible reconfigurations for the remaining nodes of the Flex Ray network
in case of node failures. Hence, through this method we can design self-reconfiguring
network-based systems enabling the handling of node failures for an increased
fault tolerance.

text: In this paper we present an approach for the configuration and reconfiguration
of FlexRay networks to increase their fault tolerance. To guarantee a correct
and deterministic system behavior, the FlexRay specification does not allow a
reconfiguration of the schedapproachule during run time. To avoid the necessity
of a complete bus restart in case of a node failure, we propose a reconfiguration
using redundant slots in the schedule and/or combine messages in existing frames
and slots, to compensate node failures and increase robustness. Our approach supports
the developer to increase the fault tolerance of the system during the design
phase. It is a heuristic, which, additionally to a determined initial configuration,
calculates possible reconfigurations for the remaining nodes of the FlexRay network
in case of a node failure, to keep the system working properly. An evaluation
by means of realistic safety-critical automotive real-time systems revealed that
it determines valid reconfigurations for up to 80% of possible individual node
failures. In summary, our approach offers major support for the developer of FlexRay
networks since the results provide helpful feedback about reconfiguration capabilities.
In an iterative design process these information can be used to determine and
optimize valid reconfigurations.

text: In this paper we present an approach to increase the fault tolerance in FlexRay
networks by introducing backup nodes to replace defect ECUs (Electronic Control
Units). In order to reduce the memory requirements of such backup nodes, we distribute
redundant tasks over different nodes and propose the distributed coordinated migration
of tasks of the defect ECU to the backup node at runtime. This approach enhances
our former work in, where we extended the FlexRay bus schedule by redundant slots
to consider changes in the communication/slot assignment and investigated and
evaluated different solutions to migrate the redundant tasks to the backup node
using the static and/or dynamic segment of the communication cycle for transmissions.
We present the approach of distributed coordination for migration and communication
instead of additional dedicated coordinator nodes to further increase the fault
tolerance. With this approach we improve the safety of FlexRay networks by avoiding
a possible single point of failure due to a dedicated coordinator node also minimizing
the necessary time needed for a reconfiguration after an ECU failure. Furthermore,
we reduce the overhead within the communication and the demand for additional
hardware components.
