Abstract: A fog controller is operable to communicate with fog nodes associated with a plurality of special purpose network connected devices. The fog controller receives, from each of a plurality of the fog nodes, an indication of one or more processing capabilities of the respective fog node. Based on the processing capabilities, the fog controller creates a fog-based service function chain that includes a set of the plurality of fog nodes. The fog controller instantiates the fog-based service function chain at the set of the plurality of fog nodes.

Abstract: Various implementations disclosed herein enable transforming mutable wireless coverage areas using network coverage vehicles (NVCs) that are orchestrated by a network coverage controller. In various implementations, the method includes receiving coverage area performance characterization values from NCVs configured to provide a plurality of mutable wireless coverage areas. In various implementations, an arrangement of the mutable wireless coverage areas mutably defines the service area, which changes in accordance with changes to the arrangement of the mutable wireless coverage areas. In various implementations, the method also includes determining NCV operation adjustments for some of the NCVs based on the received coverage area performance characterization values in accordance with a service performance metric; and, altering an arrangement of one or more of the plurality of mutable wireless coverage areas within the service area by providing the NCV operation adjustments to some of the NCVs.

Abstract: A controller device sends predictions from a machine learning module to source endpoints. The controller receives flow information and network information from a network elements in a network. The flow information is associated with source routed data flows that traverse the network in source routed network paths. The network information is associated with network characteristics of each of the network elements included in at least one of the source routed network paths. The controller analyzes the flow information and the network information with machine learning to generate a prediction of at least one metric of source routing behavior within the network. The controller sends the prediction of the at least one metric to one or more source endpoints to optimize the source routed network paths used by future source routed data flows originating from the one or more source endpoints.

Abstract: A packet is received at a device configured to provide a service function within a network service chain. A network overlay and/or segmentation identifier is extracted from a header of the packet. The service function is applied to the packet according to policies specific to a network overlay and/or segmentation identified in the network overlay and/or segmentation identifier.

Abstract: The disclosed technology addresses the need in the art for a detecting an unauthorized participant in a multiparty conferencing session. A system is configured to join a conferencing session, obtain a roster for the conferencing session via a Session Initiation Protocol (SIP) channel, and generate a roster hash value based on the roster. The system may further receive a reference hash value from a key management server and compare the reference hash value with the roster hash value. The system may determine that the roster is invalid when the reference hash value does not match the roster hash value.

Abstract: In one embodiment, a classification device in a computer network analyzes data from a given device in the computer network, and classifies the given device as a particular type of device based on the data. The classification device may then determine whether a manufacturer usage description (MUD) policy exists for the particular type of device. In response to there being no existing MUD policy for the particular type of device, the classification device may then determine patterns of the analyzed data, classify the patterns into context-based policies, and generate a derived MUD policy for the particular type of device based on the context-based policies. The classification device may then apply one of either the existing or derived MUD policy for the given device within the computer network.

Abstract: Automatic, adaptive stimulus generation includes receiving, at a network device that is associated with a network or system, analytics data that provides an indication of how the network or system is responding to a set of test stimuli introduced into the network or system to facilitate an analysis operation. The network device analyzes the analytics data based on an intended objective for the analysis operation and generates control settings based on the analyzing. The control settings control creation of a subsequent stimulus to be introduced into the network or system during subsequent execution of the analysis operation.

Abstract: Disclosed is a system and method of providing transport-level identification and isolation of container traffic. The method includes assigning, by a software-defined-network (SDN) controller in an SDN-enable cloud environment, a service-ID to a service, a tenant-ID to a tenant and/or workload-ID to yield universal cloud classification details, and extracting, from a data flow, the universal cloud classification details. The method includes receiving a policy, generating flow rules based on the policy and universal cloud classification details, and transmitting the flow rules to an openflow application to confine packet forwarding decisions for the data flow.

Abstract: In one embodiment, a service function classifier device determines a classification of a packet using one or more packet classification rules. The device selects a service function path based on the classification of the packet. The device determines one or more traffic flow characteristics based on the classification of the packet. The device generates a service function chaining (SFC) header that identifies the selected service function path and the determined one or more traffic flow characteristics. The SFC header is configured to cause a device along the service function path to forward the encapsulated packet based on the identified service function path and the determined one or more traffic flow characteristics. The device sends the packet along the selected service function path as an encapsulated packet that includes the generated SFC header.

Abstract: A community exchange gathers machine consumable modules in a centralized database. The community exchange receives information associated with the status of a computing device. One or more device tags are generated based on the first information. Each of the device tags is related to at least a portion of the status of the computing device. The community exchange stores a database of machine consumable modules in association with one or more existing tags. By cross-referencing the device tags with the existing tags, the community exchange determines whether one of the machine consumable modules is associated with the device tags. Responsive to a determination that no machine consumable module in the database is associated with the device tags, the information received from the computing device is stored as a machine consumable module associated with the device tags.
