    摘要: In general, techniques are described for providing Hot-Root Standby in Global Table Multicast (GTM) environments. For example, in such GTM environments, normally a single unicast route to the customer multicast source (“C-Source”) will be available to egress provider edge (PE) routers. As described herein, ingress PE routers may advertise multiple routes to a C-Source, including unicast routes that include Route Import Extended Communities, which are imported by egress PE routers. This enables an egress PE router to have multiple paths to the C-Source, and the egress PE router may generate multiple C-multicast source tree joins for respective ingress PE routers in order to receive respective multicast streams sourced by the C-Source from the ingress PE routers.

    摘要: Techniques are disclosed for reporting diagnostics data by a first network device to a cloud-based Wide Area Network (WAN) assurance system, responsive to the first network device detecting a communication issue with the cloud-based WAN assurance system. For example, the first network device detects an issue with sending telemetry data to the cloud-based WAN assurance system via a first communication path. In response, the first network device determines a second network device that has connectivity to the WAN assurance system. The first network device sends diagnostics data to the second network device along a second communication path for forwarding to the cloud-based WAN assurance system. The cloud-based WAN assurance system receives the diagnostics data from the second network device. The cloud-based WAN assurance system controls the second network device to remediate the first network device based on the diagnostics data.

    摘要: In some examples, a system includes a network managed by a service provider and configured to provide access to one or more objects to a set of tenants each having one or more users, the service provider and the set of tenants being part of a set of entities that form a hierarchy, and a controller having access to the network. The controller is configured to obtain data indicative of a set of parameters, where the data indicative of the set of parameters is associated with an owner entity of the set of entities, generate a rule which incorporates the set of parameters, where the rule enables the controller to control access to an object of the one or more objects, and add the rule to a rules database, wherein the rules database is accessible to the controller.

    摘要: Techniques are disclosed for identifying sets of network devices to which to deploy a software upgrade based on an importance to the network of each network device. For example, a network system obtains information identifying a number of instances of an application associated with network traffic forwarded by each network device of a plurality of network devices. The instances of the application are executed by client devices serviced by each network device in forwarding the network traffic. The network system assigns each network device to different upgrade groups based on the number of instances of the application, each upgrade group associated with a different relative priority. The network system deploys a software upgrade to each network device according to a priority of the respective upgrade group relative to a priority of the other upgrade groups.

    摘要: A network device may define a container LSP that includes multiple member LSPs. Each of the multiple member LSPs defines a path from the network device through a network of a plurality of network devices. The network device may receive traffic that includes multiple packet flows. The network device may identify a first set of packet flows that are intolerant to packet reordering. The network device may identify a second set of packet flows that are tolerant to packet reordering. The network device may distribute each of the first set of packet flows to a corresponding one of the multiple member LSPs. The network device may process the second set of packet flows to determine a distribution sequence for the second set of packet flows. The network device may distribute the second set of packet flows among the multiple member LSPs based on the distribution sequence.

    摘要: A controller device includes one or more processors and a memory for storing instructions that, when executed, cause the one or more processors to receive, from a set of network devices in a network, a time series of telemetry data; determine, using telemetry data, a threshold for a parameter of a network device of the set of network devices; in response to reception of an indication that an instant value for the parameter does not satisfy the determined threshold for the parameter, determine that an anomaly has occurred at the network device; in response to the determination, generate a user interface having first data for a first time period that occurs before the anomaly, second data for a second time period corresponding to when the anomaly occurs in the network, and third data for a third time period that occurs after the anomaly.
