A non-transitory computer readable medium comprising instructions which causes performance of operations comprising: receiving, by a second network coordination device, current state information of a client device, including a transmit counter and a receive counter, from a first network coordination device, wherein the first network coordination device is a primary network coordination device for the client device and the second network coordination device is a standby coordination device for the client device; and responsive to detecting a particular event, the second network coordination device (i) transitioning to be the primary network coordination device for the client device, (ii) incrementing the transmit counter by an offset, and (iii) transmitting a message to the client device including the incremented transmit counter is shown.

An integrated monitoring control apparatus includes a process to indicate a correspondence between a classification ID included in status information indicating status of the monitoring control device or status of an equipment subject to monitoring by the monitoring control device and a process performed on the status information, a receiver to receive the status information transmitted from the monitoring control device, and a process controller to cause performance, on the status information received by the receiver, of the process determined by the process definer based on the classification ID included in the status information.

A method and apparatus for distribution of applications amongst a number of servers, ensuring that changes to application data on a master for that application are asynchronously replicated to a number of slaves for that application. Servers may be located in geographically diverse locations; the invention permits data replication over high-latency and lossy network connections and failure-tolerance under hardware and network failure conditions. Access to applications is mediated by a distributed protocol handler which allows any request for any application to be addressed to any server, and which, when working in tandem with the replication system, pauses connections momentarily to allow seamless, consistent live-migration of applications and their state between servers. Additionally, a system which controls the aforementioned live-migration based on dynamic measurement of load generated by each application and the topological preferences of each application, in order to automatically keep servers at an optimum utilisation level.

A method includes creating communication agents in each worker node in a distributed processing cluster, creating communication agents in nodes other than the distributed processing cluster as redundant nodes, the worker nodes and redundant nodes forming a communicator group, numbering and identifying each worker node in the distributed processing cluster using the communication agents, detecting a distributed processing worker node fault using the communication agent between nodes of the distributed processing cluster, spawning a new worker node via the communication agent from one of the redundant nodes in the communicator group for use as a new worker node, rebuilding the new worker node by using the communication agent to operate with the distributed processing cluster, and starting the new worker node to join the distributed processing cluster to work with the other worker nodes utilizing the communication agents for communications between the worker nodes in the communicator group.

A method and system for re-establishing a disconnected emergency call to an emergency call network for emergency call continuation in case of Public Safety Answering Point (PSAP) failure(s) can be utilized without the need of any manual steps taken by the caller and/or the call taker. Embodiments can be configured to detect a failure in the PSAP operating the emergency call by a Next Generation Core Services (NGCS), which thereupon will not release the emergency call to the failed PSAP but will send it to a dynamically identified fallback PSAP.

Various systems and methods for implementing a software defined industrial system are described herein. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. In response to a node failing, a module may be redeployed to a replacement node. In an example, self-descriptive control applications and software modules are provided in the context of orchestratable distributed systems. The self-descriptive control applications may be executed by an orchestrator or like control device and use a module manifest to generate a control system application. For example, an edge control node of the industrial system may include a system on a chip including a microcontroller (MCU) to convert IO data. The system on a chip includes a central processing unit (CPU) in an initial inactive state, which may be changed to an activated state in response an activation signal.

A method and system for detecting ruleset misconfiguration in a computer network. The method including: generating a set of sample data flows; evaluating each of the set of sample data flows against a predetermined definition to generate a flow descriptor for each of the set of sample data flows; evaluating each of the flow descriptors against a ruleset; and generating a summary of how each of the flow descriptors perform with respect to the ruleset. The system including: a data flow sample retrieval module configured to generate flows; a policy engine configured to store and retrieve a ruleset; a packet processing engine configured to evaluate each of the data flows against a predetermined definition to generate a flow descriptor for each flows, evaluate each of the flow descriptors against a ruleset; and generate a summary of how each of the flow descriptors perform with respect to the ruleset.

A non-transitory computer-readable recording medium is provided in which a port switching program for causing a computer to execute a process including: transmitting, in response to a mirror switching instruction that specifies a migration source port and a migration destination port, a first mirror switching notification to a virtual switch that has the migration destination port to request a change of mirror setting in the migration destination port; canceling mirror setting for a transmission packet to the migration destination port in the migration source port; and canceling mirror setting for a received packet from the migration destination port in the migration source port in response to a second mirror switching notification from the virtual switch, the second mirror switching notification indicating the change of the mirror setting in the migration destination port is stored.
