In a cable network, embodiments detect and remediate a non-responsive customer premise equipment (CPE) device in a customer's premise with minimal or no interaction with a customer. Embodiments may detect and remediate a non-responsive CPE device without rebooting the non-responsive CPE device or the associated cable modem. Embodiments include troubleshooting a data link layer (e.g., Open System Interconnection (OSI) layer 2, or media access control (MAC) layer) and a network layer (e.g., OSI layer 3, or Internet layer) between a service operator network and the non-responsive CPE device. Embodiments include a guided integration and a proactive integration method, computer program product, and system to reduce and / or eliminate the need for a customer service representative to reboot a cable modem, and / or for a customer to reboot a non-responsive CPE device resulting in a fast and less disruptive service experience for the customer.

The invention relates to a multi-layer platform for electric equipment. The multi-layer platform for power equipment includes multi-layer platforms with the same structure, uprights and vertical cable channels; the two adjacent platforms are fixed and supported by the uprights; each layer of platforms includes a bottom frame and an upper part of the bottom frame. The top cable trench; at least one side of the top cable trench is provided with an installation position for placing the cabinet; the vertical cable channel is located between two adjacent platforms, and the upper and lower ends of the vertical cable channel are respectively connected to the The upper platform communicates with the top floor cable trench of the lower platform. The multi-layer platform for electric equipment provided by the invention realizes the multi-layer placement of cabinets and the connection of cables between the platforms of each layer, which can effectively save space and reduce the occupied area.

A network-to-network bridge is provided. In one embodiment, the network-to-network bridge is coupled between a main system and a subsystem system. The main system includes a slot to couple with the subsystem, wherein the slot complies with the PCIe standard. The network-to-network bridge includes a transport layer and an internet layer but lacks of a network access layer allocated between the first main system and subsystem so as to transfer data by following the PCIe standard therebetween. The network-to-network bridge transfers data between the main system and the subsystem by accessing and employing their MAC addresses, and the network-to-network bridge can be allocated in the mainboard of the main system or the subsystem.

The invention relates to a ship communication protocol conversion system and a conversion process, which are used for data exchange between a shipborne Beidou 2nd generation device and a ship Ethernet. According to the protection conversion system, a UART0 module is used for receiving and sending data of the shipborne Beidou 2nd generation device to perform communication; a Beidou 2nd generation protocol function module is used for identifying and processing Beidou 2nd generation positioning data, device state data and system log data, and sending a Beidou device instruction to the shipborne Beidou 2nd generation device; a protocol conversion module is used for performing encapsulation conversion on the data of the shipborne Beidou 2nd generation device and IEC 61162-450 standard data; an IEC 61162-450 protocol function module manages a physical layer, a data link layer, an internet layer, a transport layer and an application layer of a communication protocol stack through a logic device and an application process to establish a communication link; and a network interface module establishes a network connection with the ship Ethernet to perform communication. Therefore, the conversion system and process can enable the shipborne Beidou 2nd generation device to be used in the ship Ethernet meeting IEC 61162-450 standards, and a foundation is laid for the application of the shipborne Beidou 2nd generation device to the field of ships.

The invention discloses a water inrush perception and early warning system and method based on the Internet of Things in karst tunnels, including a multi-information perception platform layer for tunnel water inrush precursors, a sensory data network transmission, storage and analysis layer, and a disaster classification early warning layer; tunnel water inrush precursors The multi-information perception platform layer uses the sensing terminal to collect data information and distributes it to the perception data network transmission, storage and analysis layer, and the perception data network transmission, storage and analysis layer receives tunnel water inrush precursor multi-information perception platform layer transmission The data is stored in the spatial data warehouse, and the cloud computing service platform is used to analyze and process the data, and the analysis results are issued through the four-color early warning platform through the disaster grading early warning layer. Realized rapid real-time monitoring of multiple precursor information of water inrush disasters, and completed scientific storage, rapid processing, and timely release of monitoring data at the same time, reducing construction delays, construction personnel casualties, and mechanical equipment damage caused by water inrush in tunnels.

The present invention provides a flow visualization method, comprising: S1, drawing the internet layer, firewall layer, WAF layer and virtual host layer on the visualization interface according to the actual network architecture; S2, grouping the internet network, firewall, WAF and virtual host The devices in the real network architecture are associated with the devices in the real network architecture; S3, according to the connection relationship of each device in the real network architecture, draw the lines between the internet network, firewall, WAF and virtual host groups on the visual interface; S4, by highlighting Lines between the internet network, firewall, WAF and virtual host groups are displayed to represent the flow direction between devices in the current real network architecture. On the other hand, the present invention also provides a traffic visualization system, device and computer-readable medium. By establishing a visualized network architecture consistent with the actual network architecture, the protection status of the current virtual host can be seen intuitively, and the protection status of the virtual host can be changed by directly dragging and dropping.
