Abstract: An algorithm for determining redundant radios in APs is disclosed. The algorithm first performs a coverage peak flattening algorithm to predict an impact to the total coverage area if a radio in a selected AP does not transmit signals in a frequency band. If the impact to the total coverage area is acceptable, the algorithm then performs a multi-point check algorithm to determine whether the radio in the selected AP is redundant in the frequency band. After determining that the radio in the selected AP is redundant in the frequency band, the algorithm transforms the redundant radio into various services based on the network deployment and user preference.

Abstract: Techniques for classifying a network flow using a service directory. Embodiments receive a request to establish a network flow with a remote service. The request specifies a network address associated with the remote service. A classification of the remote service is determined by querying a service directory using the network address and the port identifier. Embodiments also determine a network management policy to apply to the network flow, based on the determined classification.

Abstract: A particular fat tree network node stores default routing information indicating that the particular fat tree network node can reach a plurality of parent fat tree network nodes of the particular fat tree network node. The particular fat tree network node obtains, from a first parent fat tree network node of the plurality of parent fat tree network nodes, a negative disaggregation advertisement indicating that the first parent fat tree network node cannot reach a specific destination. The particular fat tree network node determines whether the first parent fat tree network node is the only parent fat tree network node of the plurality of parent fat tree network nodes that cannot reach the specific destination. If so, the particular fat tree network node installs supplemental routing information indicating that every parent fat tree network node except the first parent fat tree network node can reach the specific destination.

Abstract: In one embodiment, a device in a network determines behavioral profiles of a plurality of nodes in the network. The behavioral profile for a particular node indicates whether the node is an occasional transmitter or a periodic transmitter. The device identifies similarly behaving nodes based on their behavioral profiles. The device assigns groups of the nodes to uplink transmission windows based on their behavioral profiles. The similarly behaving nodes that are periodic transmitters are assigned to the same uplink transmission windows and similarly behaving nodes that are occasional transmitters are assigned to different uplink transmission windows. The device controls the plurality of nodes to use their assigned uplink transmission windows via target wake time values sent to the plurality of nodes.

Abstract: A Fibre Channel (FC) or FC-over-Ethernet (FCoE) switch has ports to forward Input-Output (IO) requests, and service data transfers, between end devices in a storage area network. The switch receives at a port a time ordered sequence of IO requests for data transfers to be serviced by the port. Each IO request including a data length of the data transfer. The switch detects a microburst on the port for each IO request. To do this, the switch parses the IO request to retrieve the data length, determines a transfer time required to transfer the data length over the port, upon receiving a next IO request, determine whether a time interval between the IO request and the next IO request is less than the transfer time, and if the time interval is less than the transfer time, declaring a microburst on the port, otherwise not declaring a microburst.

For example, one method involves receiving a request to access a protected data asset, wherein the request is received from a first user device; determining whether to grant access to the protected data asset, wherein the determining comprises evaluating one or more criteria associated with the first user device, and the criteria comprises first information associated with a first policy constraint; and in response to a determination that access to the protected data asset is to be granted, granting access to the protected data asset.

Abstract: In one illustrative example, an IP network media data router includes a spine and leaf switch architecture operative to provide IP multicast delivery of media data from source devices to receiver devices without the overhead communication with a controller. The architecture can include K spine switches, K sets of L leaf switches, M data links between each leaf switch, and a plurality of bidirectional data ports connected to each leaf switch for a guaranteed non-blocking IP multicast delivery of data. A deterministic hash function a used on both the first hop router and the last hop router to ensure the same spine node is selected for flow stitching. Accordingly, without the extra communication with a centralized controller, the right spine for establishing a multicast flow can be chosen using the deterministic hash function and the distributed resource information stored on each node.

The network controller may then determine, based on the details and policy requirements for the provisioned device, a plurality of network devices that the provisioned device is configured to communicate through, and may then translate the details and policy requirements for the provisioned device into a plurality of network-device-specific policies, each respective network-device-specific policy corresponding to one of the plurality of network devices that the provisioned device is configured to communicate through. As such, the network controller may then transmit a respective network-device-specific policy of the plurality of network-device-specific policies to the plurality of network devices that the provisioned device is configured to communicate through.

Abstract: In one embodiment, a service identifies a performance issue exhibited by a first device in a first network. The service forms a set of one or more time series of one or more characteristics of the first device associated with the identified performance issue. The service generates a mapping between the set of one or more time series of one or more characteristics of the first device to one or more time series of one or more characteristics of a second device in a second network. The mapping comprises a relevancy score that quantifies a degree of similarity between the characteristics of the first and second devices. The service determines a likelihood of the second device exhibiting the performance issue based on the generated mapping and on the relevancy score. The service provides an indication of the determined likelihood to a user interface associated with the second network.

Abstract: A method for routing a request for content from a content provider through an IPv6 network is described, the IPv6 network being an information centric network (ICN) in which content is directly addressed using at least a portion of an IPv6 address. The method includes receiving, at an IPv6 network, a request for content, determining that the request does not comprise an ICN address. The method further includes intercepting the request, and translating the request into an IPv6 address in which at least a portion of the address is directed to or associated with the piece of content. Systems and methods described herein address problems arising from the interaction between IP and ICN networking models.

Abstract: A user behavior activity detection method is provided in which network traffic relating to user behavior activities in a network is monitored. Data is stored representing network traffic within a plurality of time periods, each of the time periods serving as a transaction. Subsets of the network traffic in the transactions are identified as traffic suspected of relating to certain user behavior activities. The subsets of the network traffic in the transactions are assigned into one or more groups. A determination is made of one or more detection rules for each of the one or more groups based on identifying, for each of the groups, a number of user behavior activities common to each of the subsets of the network traffic. The one or more detection rules are used to monitor future network traffic in the network to detect occurrence of the certain user behavior activities.
