A protocol state fuzzing method for security of a control plane of a distributed software-defined network is provided. The protocol state fuzzing method includes receiving input alphabets being abstract symbols of a protocol message in an ambusher of a distributed network operating system (NOS), converting the input alphabets into the protocol message, and sending the protocol message to a cluster, monitoring, by the cluster, intercommunication between instances in the distributed NOS, and selecting a set of sequences executable in the cluster and searching a cluster log for an output by executing the sequence to generate an attack result.

Examples described herein include systems and methods for providing dynamic serviceability for a software-defined data center (“SDDC”). An example method can include collecting data-center metrics from a management service that monitors the SDDC, filtering the data-center information based on a predetermined list of metrics provided by a partner entity, and translating the filtered data-center information into a partner-specific format requested by the partner entity. The example method can also include generating metadata associated with the translated data-center information and transmitting the metadata and translated data-center information to a partner site associated with the partner entity. If the partner site is not available, the method can include transmitting the information to a partner-accessible storage location and, when the partner site becomes available, identifying the storage location and failed attempt to deliver the information.

A pervasive realtime framework supports the execution of realtime software applications with high-level functions that significantly reduce the effort and time needed to develop realtime software applications in a new operating environment paradigm in which realtime connections between network nodes are pervasive. The pervasive realtime framework handles the complex tasks of connecting to communicants, virtual areas, and other network resources, as well as switching those connections in response to user inputs and thereby enables software application developers to focus on developing high-level realtime software application functionality.

Provided are a method for service status analysis, a server, and a storage medium. The method includes: for each vertex of multiple vertices in a graph database: reading out attribute data of the vertex, where the graph database is generated in advance according to a service description table, the vertex represents a service, and the attribute data of the vertex includes at least one service attribute of the service represented by the vertex; and according to the attribute data of the vertex and attribute data of each of multiple related vertices, determining a service status level of the service represented by the vertex, where each of the multiple related vertices has a propagation relationship with the vertex; and according to the service status level of each of the services represented by the vertices, analyzing a service propagation network.

Embodiments of the present invention provide a system for authenticating and tracking resource distributions of secondary users. The system is configured for receiving a registration request from a primary user, wherein the registration request is associated with registration of one or more secondary users, in response to receiving the request, generating user credentials for each of the one or more secondary users, associating the user credentials with a primary user identification of the primary user, receiving a resource distribution request from a secondary user of the one or more secondary users, authenticating the secondary user, and processing the resource distribution request based on authenticating the secondary user.

High-speed control of disaggregated network systems is implemented. A control device includes a main memory and an interface. The main memory shares management information contained in memory spaces possessed by a plurality of respective component devices connected and stores the management information as integrated management information. When the management information is to be updated, the interface transmits an update signal for updating the management information to the component devices and receives a response signal to the update signal from the component devices.

Embodiments of this application provide a network operation and maintenance method, to resolve a problem that a mainly manual network operation and maintenance method has high costs and low operation and maintenance efficiency. The method includes: A network intelligent unit obtains first network data, performs training based on the first network data to obtain a data model, and deploys the data model. The data model is a first model, a second model, or a third model. The first model is used to determine a network control instruction to be sent to an operation support system. The second model is used to determine a network control instruction to be sent to an element/network management system. The third model is used to determine a network control instruction to be sent to a network element.

A system for constructing and storing procedures for troubleshooting computer networks. A user can design and add troubleshooting steps, via a GUI, to define the procedure including annotations. Each step is configured to take an action on the network. The order of the steps can be re-arranged via the GUI. The procedure can be stored and re-executed by another user.
