“…As a result, applications that would otherwise not be schedulable are shown to utilise criticality to meet all deadlines. An alternative approach is provided by Groesbrink et al [2013Groesbrink et al [ , 2014. They allow budgets to move between virtual machines executing on a hypervisor that is itself executing on a multi-core platform.…”

This survey covers research into mixed criticality systems that has been published since Vestal's seminal paper in 2007, up until the end of 2016. The survey is organised along the lines of the major research areas within this topic. These include single processor analysis (including fixed priority and EDF scheduling, shared resources and static and synchronous scheduling), multiprocessor analysis, realistic models, and systems issues. The survey also explores the relationship between research into mixed criticality systems and other topics such as hard and soft time constraints, fault tolerant scheduling, hierarchical scheduling, cyber physical systems, probabilistic real-time systems, and industrial safety standards. CCS Concepts: •Computer systems organization → Real-time system specification; •Software and its engineering → Real-time schedulability; Real-time systems software;

“…This is highly linked to the requirement on isolation. For example, Groesbrink et al [38] utilised hypervisor-based virtualisation to separate system to independant partitions (i.e. VMs).…”

“…MultiPARTES [69] and Airbus' MP-IOV [55] used para-virtualisation [64] to establish an I/O virtualization system for a MCS; A readybuilt separation kernel (i.e., Quest-V [51]) was extended by Missimer et al [53] to support I/O virtualisation. In these methodologies, different system modes are assigned to the VMs, and a secondary scheduling between the VMs is also built to guarantee the more critical I/O requests can be served earlier (i.e., in [37], [38], partitioned RM scheduling of VMs based on periodic servers with fixed period are implemented; in [53], sporadic servers and priority inheritance bandwidthpreserving servers are built to schedule I/O requests among the VMs).…”

In mixed-criticality systems, timely handling of I/O is a key for the system being successfully implemented and functioning appropriately. The criticality levels of functions and sometimes the whole system are often dependent on the state of the I/O. An I/O system for a MCS must provide simultaneously isolation/separation, performance/efficiency and timingpredictability, as well as being able to manage I/O resource in an adaptive manner to facilitate efficient yet safe resource sharing among components of different criticality levels. Existing approaches cannot achieve all of these requirements simultaneously. This paper presents a MCS I/O management framework, termed MCS-IOV. MCS-IOV is based on hardware assisted virtualisation, which provides temporal and spatial isolation and prohibits fault propagation with small extra overhead in performance. MCS-IOV extends a real-time I/O virtualisation system, by supporting the concept of mixed criticalities and customised interfaces for schedulers, which offers good timing-preditability. MCS-IOV supports I/O driven criticality mode switch (the mode switch can be triggered by detection of unexpected I/O behaviors, e.g., a higher I/O utilization than expected) and timely I/O resource reconfiguration up on that. Finally, We evaluated and demonstrate MCS-IOV in different aspects.

The coordinated operation of navy aviation is complex and there may be hidden time conflicts. On the basis of the previous research work, this paper detected the conflicts of the time coordinated model of a sea-borne strike. Referring to the theory of temporal constraint network (STN), the paper converted the time conflicts detection problem from consistency detecting to negative cycles detecting in STN model and designs consistency detecting function based on BFCT algorithm and FIFO queue. Then, the conflict detection of coordinated actions was realized under specific combat cases and assumptions.
