Abstract:
Techniques described in this disclosure relate to configuration updates, such as performing an in-service software upgrade on a device, using virtual machines. In a routing device, a routing engine utilizes a virtual machine executing on a hypervisor to provide control plane functions. In one example, an in-service software upgrade may be performed between a first virtual machine and a second virtual machine without a managing virtual machine. More specifically, a first virtual machine in the control plane of the router may control the upgrade process, including requesting initialization of the second virtual machine, installing a new software system on the second virtual machine, and replicating state data from the first virtual machine to the second virtual machine. In this example, the first virtual machine may operate as a master virtual machine and the second virtual machine may operate as a slave virtual machine that synchronizes with the master virtual machine.
Abstract:
The control plane of a network device comprises a plurality of software processes that manage routing control operations of the device. Through a hypervisor in the control plane, a managing virtual machine controls access to a first virtual machine running a first software system to control a routing communication session between the network device and other network devices. In response to an in-service software upgrade request, the managing virtual machine initializes a second virtual machine. On the second virtual machine, the second software system is loaded. State data maintained by the managing virtual machine can be transferred to the second virtual machine, and the second virtual machine takes control of the routing communication session. During the transfer of control from the first virtual machine to the second virtual machine, techniques of “non-stop forwarding” and “graceful restart” can be implemented to minimize the effect the switchover has on the network.
