Some embodiments provide a novel way to insert a service (e.g., a third party service) in the path of a data message flow, between two machines (e.g., two VMs, two containers, etc.) in a public cloud environment. For a particular tenant of the public cloud, some embodiments create an overlay logical network with a logical overlay address space. To perform a service on data messages of a flow between two machines, the logical overlay network passes to the public cloud's underlay network the data messages with their destination address (e.g., destination IP addresses) defined in the logical overlay network. The underlay network (e.g., an underlay default downlink gateway) is configured to pass data messages with such destination addresses (e.g., with logical overlay destination addresses) to a set of one or more service machines. The underlay network (e.g., an underlay default uplink gateway) is also configured to pass to the particular tenant's public cloud gateway the processed data messages that are received from the service machine set and that are addressed to logical overlay destination addresses. The tenant's public cloud gateway is configured to forward such data messages to a logical forwarding element of the logical network, which then handles the forwarding of the data messages to the correct destination machine.

A system, method, and computer program product are provided for a determining a network situation in a communication network. In use, at least one threshold value of at least one operational parameter of a communication network is obtained, the at least one operational parameter representing at least one operational status of at least one of a computational device or a communication device. Additionally, log data of the communication network is obtained, the log data containing at least one value of the at least one operational parameter reported by at least one network entity of the communication network. The at least one value of the at least one operational parameter of the log data is compared with a corresponding threshold value of the at least one threshold value to form a detection of a network situation. Further, the detection of the network situation is reported if the at least one value of the at least one operational parameter of the log data traverses the corresponding threshold value of the at least one threshold value.

A message monitoring system includes a first electronic control unit and a second electronic control unit connected to the first electronic control unit via a communication network. In the first electronic control unit, a first message is generated; a first feature value representing a feature of the first message is calculated; a second message storing the first feature value is generated; and the first message is transmitted whereas the second message is transmitted periodically. In the second electronic control unit, the first message and the second message are received from the first electronic control unit; a second feature value representing a feature of the received first message is calculated; and a comparison is performed between (i) the first feature value stored in the received second message and (ii) the calculated second feature value; and whether the first message is normal is determined based on a result of the comparison.

Methods, systems, and devices for wireless communications are described in which radio units (RUs), distributed units (DUs), or combinations thereof, may have a single hardware configuration that may be configured to implement different functions for radio frequency (RF) and baseband processing at a base station. A desired functionality for a RU or DU may be identified, and the RU or DU may be configured to implement the functionality through run-time configuration or boot images to implement a particular set of functions that may be needed for a particular cell or deployment. A RU or DU may be reconfigured following an initial configuration to perform different functions following the reconfiguration.

The present application discloses a method and an apparatus for binding a network card in a multi-network card server, an electronic device and a computer readable storage medium. The method comprises: acquiring a target address of a target server, wherein a connection between the target server and the multi-network card server is to be established; querying an IP address library according to the target address to determine an operator to which the target address belongs, wherein the IP address library records a correspondence between IP addresses and operators; selecting a network card, according to the determined operator to which the target address belongs, corresponding to the determined operator from a plurality of network cards in the multi-network card server; and binding the selected network card to establish the connection between the multi-network card server and the target server. On the premise of avoiding the inter-operator connection, the present application realizes binding the corresponding network card to enable the automatic connection between the multi-network card server and the target server.

Methods, systems, and devices for wireless communications are described. A device may receive an indication of a subcarrier spacing (SCS) for communications in a plurality of transmission time intervals (TTIs), where a TTI include a set of symbols, a corresponding set of cyclic prefixes, and a padding duration. The device may receive a control signal indicating a configuration for the padding duration, at least a portion of which may be reallocated as one or more additional symbols with corresponding one or more additional cyclic prefixes. In some examples, the one or more additional cyclic prefixes and at least a first portion of the set of cyclic prefixes may be reduced in duration in comparison with a remaining portion of the set of cyclic prefixes. The device may communicate during the padding duration using the one or more additional symbols and the corresponding one or more additional cyclic prefixes.
