Abstract: Techniques for conversation recovery in a dialog management system are described. A system may determine, using dialog models, that a predicted action to be performed by a skill component is likely to result in an undesired response or that the skill component is unable to respond to a user input of a dialog session. Rather than informing the user that the skill component is unable to respond, the system may send data to the skill component to enable the skill component to determine a correct action responsive to the user input. The data may include an indication of the predicted action and/or entity data corresponding to the user input. The system may receive, from the skill component, response data corresponding to the user input, and may use the response data to update a dialog context for the dialog session and an inference engine of the dialog management system.

Abstract: A network security platform (NSP) device and interaction method are disclosed. The interaction method provides network packet analysis for secure transmission protocols using ephemeral keys or keys that are negotiated dynamically. The NSP may be part of an Intrusion Protection System, or firewall. The disclosed approach does not use man-in-the-middle proxy.

Decrypted data may be sent to an NSP sensor in a secure manner for analysis. Alternatively, intercepted keys used for the encrypt/decrypt operations may be sent to an NSP sensor in a secure manner every time they are changed. The NSP sensor may then use the obtained keys to decrypt traffic prior to providing it to the inspection engines. Embodiments focused on inbound traffic to a web server may coordinate between a web server and an NSP.

Abstract: This application provides a subflow establishment method. A local-end device obtains an identifier of an operator currently accessed by a network interface card of the local end device. The local-end device obtains a plurality of IP addresses of a peer-end device and identifiers of operators to which the plurality of IP addresses are homed; and establishes, by matching a plurality of operators corresponding to the local-end device and the plurality of operators corresponding to the peer-end device, a subflow between an IP address pair homed to a same operator. In this way, the established subflow does not cross operators as far as possible. This reduces negative impact of cross-operator communication of some subflows on transmission performance of a multipath connection, thereby better leveraging an advantage of the multipath connection in transmission performance in comparison with a single-path connection.

Abstract: A parametric constant resolves to different values in different contexts, but a single value within a particular context. An anchor constant is a parametric constant that allows for a degree of parametricity for an API point. The context for the anchor constant is provided by a caller to the API point. The anchor constant resolves to an anchor value that records specialization decisions for the API point within the provided context.

The class object may be accessible to the caller, but the full value of the anchor value is not accessible to the caller. The API point is executed based on the specialization decisions embodied in the anchor value.
