INTERFACE PROXY DEVICE FOR CYBER SECURITY
A system for providing cyber protection to medical devices in a medical environment is presented. The system comprises a medical device comprising software services, a backend server to maintain and provide software updates to medical devices, and an interface proxy box connected to the medical device and in communication with the backend server. The interface proxy box determines the software services resident on the medical device. The interface proxy box installs the software services determined to be resident on the medical device on the interface proxy box and configures the installed software services to match the software services resident on the medical device. The interface proxy box communicates periodically with the backend server and receives and applies security updates to the software services installed and configured on the interface proxy box. The medical device utilizes the updated software services on the interface proxy box.

Redundancy in a network centric process control system
A method for providing redundancy in a network centric process control system, where at least one node includes at least one control service as well as at least one middleware service for communicating in the process control system, where the control service and middleware service is each a separate executable running in a separate operating system process provided by a real time operating system thereof, wherein a first control service in a first node communicating via a first middleware service and implementing a first control function acts as an active control service for the first control function and a second control service communicating via a second middleware service and implementing the first control function acts as a standby control service for the first control function, the method including performing, by the first control service, the first control function through subscribing, via the first middleware service, to input process data of the first control function and publishing, via the first middleware service, output process data of the first control function, synchronizing the first control service with the second control service, and taking over, by the second control service based on a determination that a fault has occurred in the first node, the role of active control service, the taking over including publishing, by the second control service via a second middleware service provided for the second control service, the output process data of the first control function based on a subscription of the second control service to the input process data.

System and method of presenting a hybrid cloud cache as a file system
A system and methods for presenting a hybrid cloud cache as a file system. The system implements a set of standard file system command line interfaces that present the objects stored by the hybrid cloud cache to users of the system as if the users were viewing and interacting with a traditional file system. The system provides an interactive shell to the users to view the contents of the hybrid cloud cache. The system may be configured to operate on a live instance as well as on an on-disk structure of the hybrid cloud cache. The system may provide the ability to present partially cached cloud data as a file system via the interactive shell for the purposes of development, support, and troubleshooting.
Packet processing of streaming content in a communications network
Aspects of present disclosure include devices within a transmission path of streamed content forwarding received data packets of the stream to the next device or “hop” in the path prior to buffering the data packet at the device. In this method, typical buffering of the data stream may therefore occur at the destination device for presentation at a consuming device, while the devices along the transmission path may transmit a received packet before buffering. Further, devices along the path may also buffer the content stream after forwarding to fill subsequent requests for dropped data packets of the content stream. Also, in response to receiving the request for the content stream, a device may first transmit a portion of the contents of the gateway buffer to the requesting device to fill a respective buffer at the receiving device.

METHOD AND APPARATUS FOR TRANSMITTING DATA IN IOT SYSTEM, AND GATEWAY DEVICE AND STORAGE MEDIUM THEREOF
Disclosed are a method and apparatus for transmitting data in an IoT system. The method includes: determining a data type of device data sent by an IoT device when a connection between a gateway device and a server is abnormal; storing device data of a real-time data type into a first message queue of a message-oriented middleware, and storing device data of a historical data type into a second message queue of the message-oriented middleware; transmuting the device data in the first message queue to a server over a first MQTT channel and transmitting the device data in the second message queue to the server over a second MQTT channel when the connection resumes to a normal state.

Method and device for timeout monitoring
Disclosed are a method and device for timeout monitoring, comprising: determining key information of a request message, the key information including a sending time of the request message; storing the key information to a first level cache; scanning the first level cache according to a set frequency, if the first level cache includes a first request message, storing the key information of the first request message into a second level cache, the first request message being a request message for which a reply message is not received; scanning the second level cache, and determining by a message log whether a reply message is received for a second request message in the second level cache, if not, the second request message times out, the second request message is a request message in which the difference value between a sending time and a current time is greater than a time-out threshold.
