    CPC classification number: H04Q9/00

    Abstract: A method includes receiving, by a network analyzer implemented in circuitry, from a network device of a plurality of network devices, a sensor message for telemetry flow data. The sensor message indicates an interface index for a network interface, a virtual network identifier associated with a virtual network, and an IP address. The method further includes receiving, by the network analyzer, from the network device, a telemetry flow message for the telemetry flow data. The method further includes, in response to determining that the telemetry flow message includes an indication of an interface index that matches the interface index of the sensor message and that the telemetry flow message includes an indication of a virtual network identifier that matches the virtual network identifier of the sensor message, setting, by the network analyzer, the IP address as the source of the telemetry flow data.

    Abstract: This disclosure describes techniques that include collecting flow data associated with communications between network devices, and determining, based on the flow data, one or more virtual networks over which the communications are taking place. In one example, this disclosure describes a system configured to perform operations comprising: storing virtual network configuration information associated with a first virtual network and a second virtual network established within a network; collecting underlay flow data associated with communications between a first server and a second server, wherein each of the first server and the second server are implemented as bare metal servers; determining, based on the underlay flow data and the stored virtual network configuration information, that the first server and the second server have communicated over the first virtual network; and generating a user interface.

    Abstract: This disclosure describes techniques that include collecting underlay flow data within a network and associating underlay flow data with a source and a destination virtual network to enable insights into network operation and performance. In one example, this disclosure describes a method that includes identifying, for each underlay data flow, a source overlay network and a destination overlay network associated with the underlay data flow, wherein identifying includes retrieving, from one or more Ethernet Virtual Private Network (EVPN) databases, information identifying the source and destination overlay networks.

    Abstract: This disclosure describes techniques that include receiving underlay flow data from a network having an underlay network and one or more overlay network, storing information identifying, for each underlay data flow, an overlay network, displaying, within a display, a topological map of at least a portion of the underlay network, highlighting a data path through the displayed topological map, the highlighted data path extending through the underlay network from the underlay network source of the respective underlay data flow to the underlay network destination of the respective underlay data flow; receiving a request for metrics associated with the highlighted data path, wherein receiving a request includes receiving, via a graphical user interface, an indication selecting at least a portion of the highlighted data path; and displaying, proximate to the highlighted data path, metrics associated with data traffic through the selected portion of the highlighted data path.

    Abstract: This disclosure describes techniques that determine device connectivity in the absence of a network layer 2 discovery protocol such as Link Layer Discovery Protocol (LLDP). In one example, this disclosure describes a method that includes retrieving, from a bridge data store of a bridge device on a network having one or more host devices, a plurality of first interface indexes, wherein each first interface index corresponds to a network interface of network interfaces of the bridge device; retrieving, from the bridge data store, remote network addresses corresponding to the network interfaces of the bridge device, each remote network address of the remote network addresses corresponding to a second interface index; selecting a remote network address having a second interface index that matches the first interface index; determining a host device having the selected remote network address; and outputting an indication that the bridge device is coupled to the host device.
