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: This disclosure describes techniques for performing enhanced authentication of a device based on physical proximity of the device to one or more other authenticated devices. An example method includes performing a first authentication of a first device or a first user and connecting the first device to a protected resource. Based on determining that the first device is within a threshold distance of a second, authenticated, device, a reauthentication interval is selected. Based on determining that the reauthentication interval has expired, a second authentication is initiated by transmitting, to the first device or a third device associated with the first user, a request for an authentication factor.

Abstract: The present disclosure is directed to BIER forwarding over varying BSL domains, the methods including the steps of receiving, at a border node, a packet comprising a BIER header having a BIER bit string with a first bit string length; reading an incoming label of the packet comprising instructions to split the BIER header into a plurality of smaller headers associated with a plurality of smaller bit strings; generating a set of split bit masks; performing a separate bitwise AND operation on each split bit mask and the BIER bit string to generate the plurality of smaller bit strings, each copied to a corresponding smaller header of the plurality of smaller headers; and performing a lookup for each of the plurality of smaller headers on a respective forwarding table to determine one or more egress routers to which to transmit the packet.

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: Systems, methods, and computer-readable for cognitive sensor fusion management include obtaining one or more data streams from one or more sensors. Learning algorithms are used for determining whether a combination of the one or more data streams includes sufficient information for achieving a desired outcome, based on context, business verticals, or other considerations. One or more modifications are determined to at least the one or more data streams or one or more sensors based on whether the combination of the one or more data streams includes sufficient information for achieving the desired outcome. In a closed-loop system, feedback from implementing the one or more modifications can be used to update the desired outcome.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable media for determining a trust score associated with a user, comprising detecting entities near a user device operated by the user; calculating the trust score for the user based on a policy that incorporates data about the entities near the user device, the trust score being a score that is indicative of a trust worthiness of data received from the user device, wherein trusted entities near the user device result in an increased trust score, and untrusted entities near the user device result in a decreased trust score; and permitting access to a resource when the trust score is above a threshold.

Abstract: Techniques are described for generating an end-to-end distributed trace in connection with a cloud or datacenter environment. In one example, a server obtains target application telemetry data and external telemetry data associated with one or more correlation identifiers included in one or more network communications provided to a target application in the cloud or datacenter environment. The server aggregates the target application telemetry data and the external telemetry data based on the one or more correlation identifiers to generate an end-to-end distributed trace associated with the one or more network communications.

Abstract: An electronic device of a content producer generates a chunk of data, associates a location-independent name with the chunk of data, generates a signature for the chunk of data, attaches the signature to the chunk of data, and transmits the chunk of data, with the signature attached, to one or more user devices in response to respective requests. The signature is generated based on the data in the chunk, using a private key of the electronic device. The electronic device also stores information, including a specification of a public key associated with the private key, in a first ledger entry of a blockchain, to provide the one or more user devices with access to the public key. A user device may obtain the public key and use it to verify the chunk of data.

Abstract: A device associated with an enterprise receives, from a user device, a message indicating that a user of the user device has requested a service level for accessing a service while performing teleworking activities for the enterprise. The user device accesses the service via a network that includes a portion controlled by an Internet Service Provider (ISP). The enterprise has established an agreement with the ISP indicating that the ISP is to provide service levels for users who are performing teleworking activities for the enterprise via the ISP. The ISP associated with the user device is identified based on the message. A request is transmitted to the ISP to provide the service level for the portion of the network that is controlled by the ISP and the ISP provides the service level for accessing the service based on the request.
