Disclosed are various embodiments for receiving, via a network, a request from a client to establish a network tunnel over the network. A credential is received from the client in order to establish the network tunnel. The client is authenticated based upon the credential. The client negotiates, via the network, to establish the network tunnel.

The present invention discloses a method and control system for monitoring plurality of equipment in industrial plant connected over SNMP based network. Each of plurality of equipment is associated with a server which is communicatively connected with client. One or more equipment which are capable of reporting monitoring objects are identified using a configuration file. Further, polling for monitoring objects based on capability data associated with one or more equipment is performed. By proposed invention, efficient and secure configuration of plurality of equipment in SNMP based network may be achieved. Also, efficient management of network traffic may be performed. Unauthorized extraction of monitoring objects is reduced in the network.

Methods, systems, and apparatuses are provided for reservation management for client-initiated polling requests in a communication system.

A service interruption time of a client terminal is shortened.

A communication system (100) includes a plurality of servers 10 (10a and 10b) each functioning as an active system or a standby system and a relay device (20) that relays communication between a server of the active system and one or more client terminals (30) operated by clients. Each of the servers includes a priority level determining unit that determines a priority level of each of the clients, a virtual port creating unit that creates, in the server, a virtual port corresponding to a virtual LAN assigned to each of the client terminals, and a communication processing unit that instructs the relay device to change a destination of communication performed between the client terminal and the server to the virtual port. The communication processing unit gives an instruction of change of the destination of the communication in order of highest to lowest priority level of the client when a malfunction occurs in another server of the active system.

Described herein is a system and method for testing a computing device, such as a server, to minimize network impact. A computing device that is new or needs to be evaluated, such as an edge server, in a content delivery network may be determined and a sibling edge server which shares a common characteristic with the edge server may be selected. Requests received on the sibling edge server may be collected and filtered to determine a subset of the requests. The subset of the requests are transmitted to the edge server for processing and evaluation.

Server and methods for performing synchronization and resynchronization of networking information with client devices. During standard operations, client networking data discovered by a given client device are received by the server from the given client device, stored by the server, and forwarded by the server to other client devices. Client networking data from the other client devices received and stored by the server are forwarded to the given client device. Upon occurrence of a pre-defined event at the given client device preventing exchange of information between the given client device and the server, a resynchronization of the client networking data is performed between the given client device and the server. The synchronization and resynchronization mechanisms are based on unique version numbers respectively generated by the server and the given client device.

The described technology is generally directed towards transporting data out of isolated network environments. According to an embodiment, a system can comprise a processor, and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, that include receiving a request string comprising request data related to a request from a first application of a device. The operations further include intercepting a processing of the request string, and based on the intercepting, extracting usage data of a second application of the device encoded in the request string, wherein the usage data is unrelated to the request.

In some implementations, a computing device can test the client-side rendering capabilities of a map module running on a computing device. For example, the map module can include a test module that sends test data to a rendering module of the browser. The rendering module can render the test data into a rendering context based on the test data. The test module can compare the pixel data in the rendering context to expected pixel data to determine whether the rendering module is capable of accurately rendering an image based on the test data. If the rendering module is capable of accurately rendering the rendering context based on the test data, the map module can be configured to perform client-side rendering of images. For example, the map module can be configured to perform client-side rendering of map data based on map data received from a map server.

An MQTT Server infrastructure comprises an MQTT Server in operable communication with at least one of the following: a SCADA/IIoT host; a plurality of MQTT EoN Nodes; and a plurality of Sparkplug applications. The MQTT Server infrastructure provides alert and metrics on key system status indicators, system errors, and performance issues for the Sparkplug open-source specification into an MQTT Server to provide a richer system awareness of connected MQTT clients.

A method comprises creating template limited-administration ontologies, the template limited-administration ontologies each identifying a plurality of different managers, each of the different managers having distinct and limited system access privileges. A request is received for a limited-administration server system, the request being associated with a client entity. A particular template limited-administration ontology of the template limited-administration ontologies is selected based on the request. A deployment ontology is generated based on the particular template limited-administration ontology and the request. A limited-administration server system deployment package is generated based on the deployment ontology. The limited-administration server system deployment package is provided for execution, wherein execution of the limited-administration server system deployment package creates a limited-administration server system, the limited-administration server system being capable of controlling access to one or more other systems associated with the client entity, and the limited-administration server system being limited to administration according to the different managers.
