  • Patent number: 11829127
    Abstract: According to one or more embodiments of the disclosure, a first autonomous mobile robot (AMR) encounters a second AMR, while navigating a location. The first AMR receives, from the second AMR, a task list of the second AMR. The first AMR determines an adjustment to the task list of the second AMR, based in part on a comparison between the task list of the second AMR and a task list maintained by the first AMR. The first AMR sends, to the second AMR, the adjustment to the task list of the second AMR.

  • Patent number: 8806266
    Abstract: 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.

  • Patent number: 8799422
    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.

  • Patent number: 8787400
    Abstract: Routers balance network traffic among multiple paths through a network according to an amount of bandwidth that can be sent on an outgoing interface computed for each of the paths. For example, a router receives a link bandwidth for network links that are positioned between the first router and a second router of the network, and selects a plurality of forwarding paths from the first router to the second router. Upon determining that one of the network links is shared by multiple of the plurality of forwarding paths, the router computes a path bandwidth for each of the plurality of outgoing interfaces so as to account for splitting of link bandwidth of the shared network link across the multiple forwarding paths that share the network link. The router assigns packet flows to the forwarding paths based at least on the computed amount of bandwidth for each of the outgoing interfaces.
