    Abstract: A comprehensive system for capturing multicast messaging traffic volume and performance metrics across a global inventory of hosts. A single instance of the data capturing and extraction tool may be configured to be implemented across an enterprise's entire inventory of multicast messaging-configured hosts. The data capturing and extraction tool dynamically extracts multicast group addresses and corresponding metrics during the scanning of the captured traffic volume and performance data, thus eliminating the need for manual input of specified multicast group addresses. As a result, presentation of metrics on a per multicast group address basis is made possible for all multicast group addresses extracted during the scanning process. In addition, an efficient means for polling the hosts for traffic volume and performance data is realized by only polling those non-primary and workstation hosts that are currently transmitting or receiving multicast messages.

    Abstract: A method performed by a switch device including receiving, from a source host node, a frame including a MAC address of the source host node as a source MAC address; a MAC address of a destination host node as a destination MAC address, and information indicating a type of frame as a request frame; sending the frame towards the destination host node; generating a first reply frame including the MAC address of the source host node and information indicating a type of frame as a reply frame, the information indicating in a source MAC address field of the first reply frame including a switch ID, a sequence number equal to 0, a hop number equal to 1, and incoming port information that the switch device uses to forward at least one frame towards the source host node; and sending the generated first reply frame towards the source host node.

    Abstract: Embodiments of the present disclosure provide systems, methods, and non-transitory computer storage media for detecting abnormal behavior of device in an enterprise network based on an analysis of behavioral information of the device's neighbors in network. At a high level, embodiments of the present disclosure employ a hive-mind approach to determine anomalous behavior of a device in a network based on analyzing behavior information reported by neighboring devices within the network. Embodiments identify that a device is alive and connected within the network based on multiple neighboring devices reporting behavioral information about the device; however, the device may be dysfunctional and failing to report its own information. By aggregating and analyzing behavioral information of a device based on the reporting information of its neighboring devices, embodiments of the present disclosure are able to determine whether a device is healthy even when the device is unable to report its own information.
