Disclosed is a method and a device for protecting service reliability, and the service reliability in the network virtualization system provided by the present disclosure may be ensured. In an embodiment of the present disclosure, a master node having a control function obtains the current service type information and notifies a slave node of the current service type information, for enabling the slave node to determine a main virtual link and a backup virtual link according to the service type information and to perform the failure detection, and when detecting that the main virtual link has failure and the backup virtual link has no failure, a service data message is switched to be transmitted on the backup virtual link, to ensure non-interrupted transmission of a service data message in a brand-new system architecture provided by the present disclosure, so as to ensure the service reliability.

A specification of an intent that identifies a desired service and a reference architecture is received. The desired service is rendered to provide instructions for dispatch to a plurality of devices having roles. Rendering the desired service includes invoking a service rendering program function based on the reference architecture and a role of a specific device. A new reference architecture may be implemented by specifying a new service rendering program function for the new reference architecture.

A reliable network function virtualization (rVNF) system includes a virtualized network function (VNF) application instance that includes a plurality of physical VNF instances. A load balancer provides an interface between a client and the VNF application instance. A load balancer interface facilitates delivery of packets related to a particular user context to the same physical VNF instance. A communication interface facilitates communication between the client and the VNF application instance. Application storage stores session data associated with the VNF application instance.

An NR network slicing architecture may be used to facilitate network slice discovery and selection. Mechanisms to discover and select network slices may differ depending on whether a user equipment is in an idle mode or a connected mode. Further, in various examples, the network slice discovery and selection may be performed by a UE, a radio access network (RAN), or a core network (CN), based on a variety of selection criteria.

Some embodiments provide a method for presenting a visualization of a topology for a logical network. In response to receiving a selection of a particular user interface (UI) item representing a particular group of logical elements, the method presents one or more filter UI items for the particular group of logical elements. Each filter UI item corresponds to a different attribute associated with the logical elements. Upon receiving selection of one or more attribute states for each attribute for which a filter UI item is presented, the method identifies logical elements in the group of logical elements that match the selected attribute states. The method presents, in the UI, an expanded version of the particular group of logical elements that emphasizes the identified logical elements that match the selected attribute states.

Provided is a process including: obtaining, with a network controls engine, network traffic, wherein: the network traffic is sent across the network between source computing devices and destination computing devices; at least one of the source or destination computing devices are on a network carrying the network traffic; and the network has a plurality of computing devices causing the network traffic and which are assigned addresses on the network; applying, with the network controls engine, a plurality of rules to the network traffic to identify rules with criteria satisfied by the network traffic; and causing, with the network controls engine, one or more actions prescribed by one or more identified rules with criteria satisfied by the network traffic.

Provided is a process including: obtaining, with a network controller, a current state of a network; causing, with the network controller, a graphical user interface to be presented that depicts at least part of the network graph and includes user-inputs by which a user requests changes to the network graph; receiving, with the network controller, a request input to modify the network graph; and modifying, with the network controller, the network graph and enforcing the modification.

A building network system of a building includes a network system. The network system includes one or more processing circuits. The one or more processing circuits are configured to receive network data from a building network of the building, the network data associated with a plurality of pieces of building equipment of the building. The one or more processing circuits are configured to generate a digital network twin of the building network based on the network data, the digital network twin representing the plurality of pieces of building equipment and relationships between the plurality of pieces of building equipment. The one or more processing circuits are configured to identify one or more network updates to the building network based on the digital network twin. The one or more processing circuits are configured to deploy the one or more network updates to the building network.

A device for configuring a virtualized network function, configured for use in a virtualized communication network, is disclosed. The device is configured to receive a request to configure the virtualized network function. The device is also configured to obtain at least one parameter for implementing an elementary component of the virtualized network function in a virtualized communication network, to be added to a basic virtualized network function. The device is also configured to compose the virtualized network function from at least one elementary component and from the parameter for implementing the at least one obtained elementary component.

Embodiments of the invention are directed to a computer-implemented method for monitoring a computerized network comprising several nodes that are, each, configured for receiving and/or sending data packets via one or more communication channels, such that physical queues of data packets arriving at and/or departing from each of the nodes may form in said one or more communication channels. According to this method, virtual queues are maintained, wherein each of said virtual queues simulates a queue of data packets in a virtual channel associated to one of said one or more communication channels, wherein the service rate of said virtual channel can be varied. The virtual queues maintained are further monitored. Finally, this method comprises varying a service rate of one or more virtual channels, on which queues are respectively simulated by one or more of the virtual queues maintained.
