Provided herein are exemplary systems and methods for an architecture for converged industrial control and real time applications, the architecture comprising a physical network port, a switching module, an embedded ARM core, a network interface controller, and a multi-core computing module. According to further exemplary embodiments, the physical network port is an ethernet port capable of supporting a real-time field bus. The switching module may be configured to support a multiport ethernet switch. The switching module may also be configured to enable a backplane mesh to interconnect multiple foglets. Additionally, the embedded ARM core may be within the switching module, and the embedded ARM core may be configured to support virtualization.

Architecture for converged industrial control and real time applications

Adaptive scheduling of compute functions in a fog network is described herein. An example method includes synchronizing kernel and hypervisor scheduling of applications used to control one or more edge devices using a global schedule, wherein the global schedule comprises timeslots for applications, and adapting the timeslots in real-time or near real-time based on application-based time related feedback that is indicative of time delays.

Adaptive scheduling for edge devices and networks

According to some exemplary embodiments, the present disclosure is directed to a secure edge datastream processing and distribution system comprising a trusted datastream with metadata indicating ownership and access rights added at an edge. Further embodiments include sensors, machines or robots sending sensor data attributes to a fog operating system data pipeline, the fog operating system data pipeline sending dynamic data tags to secure containers and/or the fog operating system data pipeline sending role and org assignment data to secure containers. The secure containers may send correlated edge analytics to an authorization policy engine, and/or the secure containers may send datastream identification definition data to an authorization policy engine.

Systems and methods for designing and securing edge data processing pipelines

Disclosed herein are enhancements for operating an input/output (I/O) management cluster with end I/O devices. In one implementation, a method of operating an I/O cluster includes, in a first I/O management node of the I/O management cluster, executing a first application to manage data for an I/O device communicatively coupled via at least one switch to the first I/O management node. The method further provides identifying a failure in the first I/O management node related to processing the data for the I/O device and, in response to the failure, configuring the at least one switch to communicate the data for the I/O device with a second I/O management node of the I/O management cluster. The method also includes, in the second I/O management node and after configuring the at least one switch, executing a second application to manage the data for the I/O device.

High availability input/output management nodes

Provided herein are exemplary systems and methods for a fog computing facilitated flexible factory including establishing a physical production process as part of a work cell, establishing a sensing process as part of the work cell for the physical production process, establishing a monitoring process for the sensing process and the physical production process, establishing a managing process for the monitoring process, the sensing process and the physical production process, establishing a planning process for the managing process, the monitoring process, the sensing process and the physical production process, and establishing a fog node as part of the work cell for all of the processes.

Fog computing facilitated flexible factory

In one embodiment, a packet switching device creates multiple virtual packet switching devices within the same physical packet switching device using virtual machines and sharing particular physical resources of the packet switching device. One embodiment uses this functionality to change the operating version (e.g., upgrade or downgrade) of the packet switching device by originally operating according to a first operating version, operating according to both a first and second operating version, and then ceasing operating according to the first operating version. Using such a technique, a packet switching device can be upgraded or downgraded while fully operating (e.g., without having to reboot line cards and route processing engines).

Virtual machines in a packet switching device

A flexible scheduler in an ATM switch. The scheduler enables each connection to be served fairly according to associated quality of service parameters, while enabling several other features. A connection can be shaped while minimizing additional memory and processing requirements. Specifically, the conformance time of cells of a connections need not be stored when significant backlog exists in the transmission of the cells. The shaping rate can be dynamically varied. Sequence of cells forming a frame are buffered in the ATM switch until the end of frame cell is received. All the cells of a frame are then sent in quick succession.

Flexible scheduler in an asynchronous transfer mode (ATM) switch

An ATM switch supporting multicast transmissions and efficient transmission of frames. A cell is received on a multicast connection and transmitted on several branches/ports. Instead of copying a multicast cell several times for each output branch, only one copy of each multicast cell is maintained. The cell order and the stored cell data form a physical queue. Several logical queues are maintained, one for each output branch. In one embodiment, linked lists are used to maintain the queues. A cell in the physical queue is deleted after all logical queues traverse that cell. A shared tail pointer is used for all the logical queues to minimize additional processing and memory requirements due to the usage of logical queues. The queues enable cells forming a frame to be buffered until the end of frame cell is received, which provides for efficient handling of frames.
