Abstract: In one embodiment, a device in a network extracts words from traffic data for a particular endpoint node in the network. The device determines one or more topical categories associated with the particular endpoint node by applying a machine learning-based topical model to the extracted words. The device identifies one or more similar endpoint nodes in the network based on the determined one or more topical categories associated with the particular endpoint node and on one or more topical categories associated with the one or more similar endpoint nodes. The device determines a device type for the particular endpoint node based on a device type associated with the one or more similar endpoint nodes.

Abstract: In one embodiment, a service monitors collection of telemetry data by a telemetry exporter in a network. The telemetry exporter collects the telemetry data from a plurality of interfaces via which a plurality of encrypted traffic flows flow. The telemetry exporter also sends the collected telemetry data to a traffic analysis service for analysis. The service determines that a cost associated with the collection of the telemetry data by the telemetry exporter exceeds a cost threshold. The service selects a subset of the interfaces from which telemetry data is to be captured by the telemetry exporter, based in part on a determination that the cost associated with the collection of the telemetry data exceeds the cost threshold. The service controls the telemetry exporter to collect telemetry data to for a subset of the plurality of encrypted traffic flows using the selected subset of interfaces.

Abstract: Presented herein are object filtering techniques that optimize the communication of information over an infrastructure that supports publish-subscribe (pub-sub) and direct query (synchronization) communication. In the object filtering techniques, a single information publisher can share that information in an associated object graph with many different consumers over the infrastructure without sharing the entire object graph.
Abstract translation: 这里提出的是通过支持发布订阅（pub-sub）和直接查询（同步）通信的基础设施优化信息通信的对象过滤技术。 在对象过滤技术中，单个信息发布者可以在相关对象图中与基础架构上的许多不同的消费者共享该信息，而不共享整个对象图。

Abstract: Presented herein are techniques for adding a secure control layer to a distributed communication fabric that supports publish-subscribe (pub-sub) and direct query (synchronization) communication. The secure control layer is configured to perform policy-based authentication techniques to securely manage the exchange of data/information within the communication fabric and enable registration/discovery of new capabilities.
