A method and apparatus of a device that simulates a plurality of network elements is described. In an exemplary embodiment, the device receives network topology information for the plurality of simulated network elements. The device further instantiates a container for each of the plurality of simulated network elements. The device additionally configures a set of processes for each of the plurality of containers, where each of the set of processes simulates at least one of the plurality of simulated network elements. The plurality of set of processes further implements a network topology represented by the network topology information. The device performs a test of the network topology and saves the results of the test.

A method and an apparatus for updating a gateway resource, and an Internet of Things (IoT) control platform, which belong to the field of IoT. The method is applicable to the IoT control platform connected to each gateway device, and the gateway device is connected to an IoT device. The method includes: acquiring a model change message including a change model identifier of a changed model, wherein different IoT devices correspond to different models, and each model contains measuring point information of a measuring point in the IoT device; determining an associated template based on the change model identifier and updating the associated template, the associated template containing a corresponding relationship between the measuring point information and a measuring point identifier in the changed model, and the measuring point identifier being applicable to a measuring point data message sent by the IoT device; determining a target gateway device that uses the associated template; and issuing a gateway resource update package to the target gateway device, the target gateway device being configured to update the gateway resource based on the gateway resource update package.

The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding enhancement of traffic detection and routing in virtualized environment. The method comprises receiving information regarding an installation of an application to a server, the information comprising a detection pattern used for detecting a data flow to be routed via the application to be installed, establishing a routing rule based on the detection pattern, and sending the routing rule to the server into which the application is to be installed.

Web-enabled routers are remotely and securely administered in a centralized fashion. A server for configuring a remotely configurable router on a computer network includes a memory to store a plurality of router configuration profiles that include a first router configuration profile associated with the remotely configurable router at a first instant in time. A server may also include a network interface to receive a request to reconfigure the remotely configurable router via the computer network. A server may also include a processor, operably coupled to the network interface and to the memory, that receives instructions to provide a second router configuration profile to the remotely configurable router for installation on the remotely configured router. The processor may also provide the first router configuration profile to the remotely configurable router in response to an indication that the second router configuration profile was not successfully installed on the remotely configurable router.

Techniques are disclosed for deploying software upgrades to a mixed network of In-Service Software Upgrade (ISSU)-capable and ISSU-incapable network devices without interrupting network traffic serviced by the mixed network. In one example, a centralized controller for a network determines that first network devices of a plurality of network devices for the network are In-Service Software Upgrade (ISSU)-capable and second network devices of the plurality of network devices are not ISSU-capable. The centralized controller transmits messages instructing the first network devices to perform an ISSU operation. Further, the centralized controller transmits messages instructing each network device of the second network devices to transmit a message to peer network devices of the network device, the message indicating that the network device is not ISSU-capable. In response to receiving the message indicating that the network device is not ISSU-capable, the peer network devices redirect traffic to avoid the network device.

Various embodiments are provided for implementing instruction initialization in a dataflow architecture in a computing environment. A data packet may be transmitted from a selected node to one or more of a plurality of nodes using one or more existing data paths in an initialization network. A determination operation is performed to determine whether one or more of a plurality of nodes is a target node intended for the data packet. Those of the plurality of nodes determined to be a target node initialize one or more components of the target node using the data packet. The data packet may be forwarded by each of the one or more of a plurality of nodes to a subsequent node in the initialization network.

Systems, methods, and non-transitory computer-readable storage media for stage upgrades in a network. The system generates graph-data structured based representations of devices in the network, wherein respective attributes of the representations is selected based on respective services provided by the devices to tenants in the network and identities of respective tenants serviced by the devices. Next, the system generates a graph showing a distribution of the devices in the network according to the representations, wherein the representations are interconnected in the graph based on service roles of associated devices with respect to tenants in the network and other devices associated with the tenants. The system then schedules an upgrade of devices based on the graph, the upgrade being scheduled in stages, each stage including devices selected for upgrade in that stage, wherein the devices for each stage are selected by identifying devices having respective representations assigned to that specific stage.

In one embodiment, a device in a network receives a path computation agent configured to determine a path in the network that satisfies an objective function. The device executes the path computation agent to update state information regarding the network maintained by the path computation agent. The device selects a neighbor of the device in the network to execute the path computation agent based on the updated state information regarding the network. The device instructs the selected neighbor to execute the path computation agent with the updated state information regarding the network. The device unloads the path computation agent from the device after selecting the neighbor of the device to execute the path computation agent.

Systems herein allow an administrator to efficiently set up user devices for use in a classroom environment. A management server can display a graphical user interface that includes selection options for defining and using carts of user devices. The carts can be selected and assigned to classes. The GUI also allows the administrator to specify which applications a class will use. Based on these selections, the management server can then manage which user devices install which applications, and allocate licenses accordingly.
