摘要： Systems and methods are disclosed herein for monitoring health of each switch of a plurality of switches on a network by selectively mirroring packets transmitted by each switch of the plurality of switches. In some embodiments, control circuitry generates a plurality of mirroring parameters, each mirroring parameter comprising an instruction to mirror a respective type of packet. The control circuitry transmits the plurality of mirroring parameters to each switch of the plurality of switches on the network, and receives, from a switch, a packet that was mirrored by the switch according to a mirroring parameter of the plurality of mirroring parameters. The control circuitry determines the respective type of the packet, executes an analysis of contents of the packet based on the respective type of the packet, and determines a health of the switch based on results of the analysis.

摘要： Disclosed herein are system, method, and computer program product aspects for generating and/or using virtual node(s) (e.g., virtual SPB node(s)) in a multi-area fabric (e.g., a multi-area SPB fabric). A multi-area network includes a first network area including a first set of network nodes. The multi-area network further includes a second network area including a second set of network nodes, where the second set of network nodes is outside of the first network area. The multi-area network further includes a virtual node including a logical Intermediate System to Intermediate System (ISIS) node representing at least one of the first set of network nodes and the second set of network nodes.

摘要： Disclosed herein are system, method, and computer program product embodiments for providing an anomaly detection system. Some aspects of this disclosure include a method for detecting anomaly in a network device. The method includes determining one or more similarity values between a flow vector corresponding to a flow associated with the network device and one or more flow clusters associated with the network device. The method further includes determining a maximum similarity value as a maximum of the one or more similarity values and comparing the maximum similarity value to a threshold. The method also includes, in response to the maximum similarity value being equal to or greater than the threshold, updating a flow cluster associated with the maximum similarity value. The method also includes, in response to the maximum similarity measure being less than the threshold, detecting the anomaly in the network device.

摘要： Provided herein are systems and methods for determining relationships between events occurring in networks. Notifications describing events occurring in networks can be received and processed to determine groups of network event types. A root-cause network can be generated based on the events, with the nodes of the root-cause network representing different event types and the edges of the root-cause network indicating directional, causal relationships between the nodes. A received network event can be processed to determine potential causes of the received network event based on the root-cause network and other events received by the network.

摘要： Disclosed herein are system, method, and computer program product embodiments for analyzing a network. An embodiment operates by a network entity from a distributed ledger receiving a notification regarding network information received by the distributed ledger. The entity is associated with a smart contract having one or more conditions that correspond to the network information. The network information is compared with one or more conditions of the smart contract that correspond to the network information. In response to the network information meeting or exceeding a condition of the one or more conditions of the smart contract, the condition is triggered. Further, a transaction to validate an action corresponding to the condition is generated, and the transaction is sent to the distributed ledger. In response to receiving a positive validation from the distributed ledger, the action corresponding to the condition is performed.

摘要： Disclosed herein are system, method, and computer program product aspects for multiple instance Intermediate System to Intermediate System (IS-IS or ISIS) for a multi-area fabric. A network area in a multi-area fabric includes one or more network nodes and a boundary node shared with an other network area of the multi-area fabric outside of the network area. The boundary node can include a first ISIS instance associated with the network area and a second ISIS instance associated with the other network area. The second ISIS instance can be configured to pass information associated with the other network area to the first ISIS instance.

摘要： A multicast frame directed to a plurality of devices coupled to a network can be received, where the plurality of devices comprising at least one intended recipient device and at least one unintended recipient device. A destination unicast address corresponding to an intended recipient device can be identified. The multicast frame can be converted into a unicast frame directed to the intended recipient device, the unicast frame configured with the destination unicast address. The unicast frame can be blocked from accessing the unintended recipient device. The unicast frame can be provided to the intended recipient device.
