Abstract: A method includes associating anomalous first text, from a first unstructured data set, with a first classification; processing the first unstructured data set using at least one of ML or AI to identify a second text that is in close context to the first text, and adding the second text to a text list associated with the first classification; enriching the text list by processing the second text to generate a third text, and adding the third text to the text list to produce an enriched text list and such that the third text is also associated with the first classification; matching the text in the enriched text list to text in a second unstructured data set; and classifying the text in the second unstructured data set as having the first classification when the text in the second unstructured data set matches text in the enriched text list.

Abstract: A method is performed by a network controller that is configured to control routers configured to forward a multicast flow downstream from a first hop router that is a root of a multicast tree formed by the routers to last hop routers that terminate branches of the multicast tree, respectively. The method includes collecting operational configuration information from the routers and constructing a topological view of the multicast tree based on the operational configuration information; causing the routers to forward multicast probes downstream from the first hop router along all of the branches toward the last hop routers to trace the multicast tree; receiving, from particular ones of the last hop routers that received the multicast probes, indications that the multicast probes were received; and detecting failures in the multicast tree based on the indications and the topological view.

Abstract: Federation policy exchange is provided in response to receiving a sharing query from an Access Point (AP) indicating that an associated wireless network supports federated identities with data sharing, determining whether the sharing query is within sharing preferences; and in response to determining that the sharing query is within the sharing preferences, transmitting, to the AP, a positive response for identity sharing that authorizes collection and sharing of identity data with at least one entity identified in a sharing policy for the associated wireless network. In various embodiments, federation policy exchange includes transmitting a support notification, via an AP, indicating support for federated identities with data sharing within a wireless network associated with the AP; and in response to receiving a first identify sharing preference from a User Equipment (UE) that indicates that negotiation is preferred, transmitting a sharing policy for the wireless network to the UE.

Abstract: In one embodiment, a service chain data packet is instrumented as it is communicated among network nodes in a network providing service-level and/or networking operations visibility. The service chain data packet includes a particular header identifying a service group defining one or more service functions, and is a data packet and not a probe packet. A network node adds networking and/or service-layer operations data to the particular service chain data packet, such as, but not limited to, in the particular header. Such networking operations data includes a performance metric or attribute related to the transport of the particular service chain packet in the network. Such service-layer operations data includes a performance metric or attribute related to the service-level processing of the particular service chain data packet in the network.

Abstract: This disclosure describes techniques for authentication using wearable devices. An example method includes determining that a user is wearing a secondary device; determining that the secondary device has detected a signal output by a primary device; determining that the user has confirmed an authentication factor output by the primary device; and enabling the user to access a secured resource via the primary device.

Abstract: Methods and devices provide fault injection testing techniques in a production network environment without risking service outages for hosted computing services, by providing examples of a remote network controller configured to communicate with network devices of a network; a remote fault injection communication protocol configuring a remote network controller in communication with a network device to signal a failure injection; and a failure injection module configuring a network device to configure a network device processor to implement a failure injection signaled according to the remote failure injection communication protocol. The method includes a network controller transmitting a failure injection signal in a control plane packet over a network connection to a network device, and the network device creating a child process by executing, in a dedicated runtime environment, a copy of one or more processes impacted by a parsed failure type.

Abstract: A system and method for creating a context-aware, conversational chat bot or agent in multi-party conversations where participants have different levels of security access to information and the bot operates in one or more modes depending on the business context of the multi-user collaboration virtual workspace. The methods include adding a bot, as a participant, to a virtual workspace that is a multi-user collaboration workspace, obtaining, at a bot application server, context of the virtual workspace, setting, by the bot application server, a skill set for the bot from among a plurality of skill sets. The skill set varies based on the context of the virtual workspace. The methods further include configuring, by the bot application server, the bot to perform at least one task in the virtual workspace based on the skill set.

Abstract: Techniques are provided for an “on demand” or event-triggered end user monitoring/remote user monitoring (EUM/RUM) solution that is activated when the user has requested it, or an event (conditions of which are set by a user) occurs that triggers activation of the EUM/RUM solution. This EUM/RUM may be completely integrated into an enterprise IT Help Desk system, whereby support “tickets” are automatically generated when the monitoring solution is instantiated.

Abstract: Techniques for initiator-based data-plane validation of segment routed, multiprotocol label switched (MPLS) networks are described herein. In examples, an initiating node may determine to validate data-plane connectivity associated with a network path of the MPLS network. The initiating node may store validation data in a local memory of the initiating node. In examples, the initiating node may send a probe message that includes a request for identification data associated with a terminating node. The terminating node may send a probe reply message that includes the identification data, as well as, in some examples, a code that instructs the initiating node to perform validation. In examples, the initiating node may use the validation data stored in memory to compare to the identification data received from the terminating node to validate data-plane connectivity. In some examples, the initiating node may indicate a positive or negative response after performing the validation.

Abstract: Aggregation of cross domain service level indications provide an estimate of available end to end error budget within a service chain of a network system. In some embodiments, service level indications are obtained from a plurality of sub-domains, and aggregated to determine an end to end reliability score. The end to end reliability score is then distributed one or more of the sub-domains. The sub-domains then consider whether to implement a change based on local service level indications as well as the end to end reliability score. In other embodiments, a sub-domain requests approval to implement a change from an error manager. The error manager consults the end to end reliability score to determine whether adequate margin exists in the service chain to allow the change to occur, while still meeting service level objectives of the service chain. The error manager conditionally approves the request based on the determination.
