摘要： Techniques are described for providing high availability for a network device, e.g., a router, using full memory replication between a primary virtual machine (VM) and a standby VM running on the network device. In one example, the techniques provide hot-standby high availability for a router by initializing a primary VM and a standby VM on the router at the same time. In another example, the techniques provide high availability for the router by initializing a standby VM on the router upon detecting a failure of the primary VM. In both examples, the primary VM controls the routing functionality and periodically stores a full memory state. Upon a failure of the primary VM, a hypervisor may perform a full memory replication between the primary VM and the standby VM. The standby VM may then take control of the routing functionality at the last stored state of the memory.
摘要翻译：描述了用于为网络设备（例如路由器）提供高可用性的技术，其使用在主虚拟机（VM）和在网络设备上运行的备用虚拟机之间的完全存储器复制。在一个示例中，这些技术通过在路由器上同时初始化主VM和备用虚拟机来为路由器提供热备用高可用性。在另一个示例中，这些技术通过在检测到主VM的故障时在路由器上初始化备用虚拟机来为路由器提供高可用性。在这两个示例中，主虚拟机控制路由功能并定期存储完整的内存状态。在主虚拟机发生故障时，管理程序可能会在主虚拟机和备用虚拟机之间执行完整的内存复制。然后，备用VM可以在存储器的最后存储状态下控制路由功能。

摘要： 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.

摘要： 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.
