Abstract: Techniques are described for distributing network device tasks across virtual machines executing in a computing cloud. A network device includes a network interface to send and receive messages, a routing unit comprising one or more processors configured to execute a version of a network operating system, and a virtual machine agent. The virtual machine agent is configured to identify a virtual machine executing at a computing cloud communicatively coupled to the network device, wherein the identified virtual machine executes an instance of the version of the network operating system, to send, using the at least one network interface and to the virtual machine, a request to perform a task, and to receive, using the at least one network interface and from the virtual machine, a task response that includes a result of performing the task. The routing unit is configured to update the network device based on the result.

Abstract: A system includes a storage device to store information associated with virtual nodes that correspond to network nodes. The system also includes a server to install a virtual node that corresponds to one of the network nodes, based on the information associated with the virtual node, where installing the virtual node includes creating a logical interface via which traffic is to be sent to, or received from, other virtual nodes; start the virtual node to create an operating virtual node based on a copy of an operating system that is run on the network node, where starting the virtual node causes the operational virtual node to execute the copy of the operating system; and cause the operating virtual node to communicate with a virtual network that includes the virtual nodes, where causing the operating virtual node to communicate with the virtual network enables the operating virtual node to receive or forward traffic associated with the virtual network.
