Abstract: The techniques describe a network device comprising one or more processors configured to: receive configuration data configuring a plurality of virtual network nodes, wherein the configuration data configures a virtual client node including a corresponding line card having a port connected to a first customer network device, and configures a virtual core node including a corresponding line card having a port connected to a core network; provision a layer-2 (L2) circuit that includes, as an access interface, an interface logically connecting the virtual client node and virtual core node, wherein the L2 circuit provides connectivity between the virtual client node and a remote virtual client node; and forward, via the L2 circuit, packets between the virtual client node and the remote virtual client node to realize a logical network between the first customer network device and a second customer network device connected to the remote virtual PE node.

Abstract: In general, techniques are described for providing diversity in simulation datasets during modeling. A device comprising a memory and a processor may be configured to perform the techniques. The memory may store simulation configuration files for conducting simulations of the network device within a test environment. The processor may conduct, based on the simulation configuration files, each of the simulations with respect to the network device to collect corresponding simulation datasets indicative of an operating state of the network device. The processor may determine a level of similarity between the simulation datasets, and select, responsive to a comparison of the level of similarity to a diversity threshold, a subset of the simulation datasets. The processor may generate, based on the selected subset of the simulation datasets, a model representative of the network device that predicts, responsive to configuration parameters for the network device, an operating state of the network device.

Abstract: In general, techniques are described for providing network device modeling in preconfigured network modeling environments. A device comprising a memory and a processor may be configured to perform the techniques. The processor may interface with a network device within the preconfigured network environment to iteratively adapt pre-defined configuration objects of the network device. The processor may conduct, for each iteration of the adaptation of the pre-defined configuration objects, a simulation to collect a simulation dataset representative of an operating state of the network device. The processor may generate, based on the operational data, a model representative of the network device that predicts, responsive to configuration parameters for the network device, an operating state of the network device. The memory may store the model.
