Abstract: Systems and methods for application performance management across one or more networks are disclosed. A system includes a plurality of geographically distributed computing devices executing one or more applications. A plurality of collectors are distributed across the one or more networks, each collector being positioned proximate a respective computing device. The collectors may sample, by each of the plurality of collectors, a plurality of trace events received from the applications executing on the computing devices proximate the collector. The collectors may retain in memory sampled trace events that meet a configurable attribute. The collectors may use probabilistic sets and tail-based sampling to determine root events and policies for identifying relevant traces. Benefits can be achieved in bandwidth savings, network cost and cyber security.

Abstract: Executable code comprising a local file system is stored at a collaboration system server for downloading. The remote collaboration system responds to a message from a user device to download the local file system. The local file system to be downloaded is configured to operate on the user device so as to issue requests from the user device to perform an initial access to server-side collaboration data. The collaboration system responds to such requests by predicting interests of the user, which predictions are used to retrieve additional server-side collaboration data. The additional server-side collaboration data is sent to the user device and stored on the user device in an area for locally-stored collaboration system information. The user provides search terms for searching the locally-stored collaboration system information, and results are displayed on the user device. The results are displayed without the need to perform additional communications with remote collaboration system.

Abstract: A method (1000) for performance modeling of a plurality of microservices (215) includes deploying the plurality of microservices (215) within a network (1260). The plurality of microservices (215) are communicatively coupled to generate at least one service chain (310) for providing at least one service. Based on a resource allocation configuration, an initial set of training data for the plurality of microservices within the network (1260) is determined. At least a portion of data is excluded from the initial set of training data to generate a subset of training data. A Quality of Service (QoS) behaviour model is generated based on the subset of the training data.

Abstract: The properties of a plurality of operational units are estimated by generating a central system state graph model representing the properties of the plurality of operational units as probabilities of transitions between states for the plurality of operational units, where the states represent operational data. Then a respective updated system state graph model is generated for each of the plurality of operational units, based on the central system state graph model and based on new operational data for the respective operational unit. A distance measure is determined between the respective updated system state graph models. If the distance measure fulfils a divergence criterion, a plurality of new central system state graph models are generated, each representing the properties of a respective subset of the plurality of operational units as the probabilities of transitions between states for the respective subset of the plurality of operational units.

Abstract: Embodiments described herein provide a system for facilitating dynamic content distribution in an enterprise environment. During operation, the system determines a set of logical groups based on a set of grouping criteria. A respective logical group can include one or more devices managed by a controller and a network that provides connections among the one or more devices. The system categorizes the set of logical groups based on exogenous information associated with a respective logical group and determines a corresponding condition of measurement for a respective category of links in the enterprise environment. The system then schedules a link for measurement based on the condition of measurement and the categorization of the set of logical groups.

Abstract: A method and a system for automated switchover timer's tuning on network systems or Next Generation Emergency Systems configured so that the sending, by a master node, of a heartbeat and/or ARP ping to one or more backup nodes and/or a surveillance unit according to preconfigured switchover timer values can occur to check if the master node is still active. One or more backup nodes and/or a surveillance unit, can use an additional first Session Initiation Protocol (SIP) OPTION message to the master node after receiving the heartbeat and/or the ARP ping or if the heartbeat and/or ARP ping fails to be received according to the switchover timer values. An administrator or an administrative unit of the network can perform a switchover or failover to a backup node in case the first SIP OPTION message is not answered with a suitable response by the master node.

Abstract: Systems and methods are described for enabling graceful recovery of network connections in a virtual machine instance that has been migrated or temporarily halted. To prevent the virtual machine instance from attempting to reuse open connections, which might fail due to migration or halting, a host device identifies open connections just prior to halting the virtual machine instance on the host, and transmits to the virtual machine instance termination signals for the open connections. The host device may further transmit termination signals to the other parties to such connections. Each termination signal may be formatted so as to appear to originate from the other party to the connection, causing both parties to synchronize their knowledge of the connection. On reactivation, the virtual machine instance can recovery the connections without errors associated with attempted utilization of broken connections.

Abstract: Advanced user experience study can be accomplished by enabling recording on a device such as a smart phone, providing a participant with one or more survey questions and a task. Typically, the participants are recorded and redirected to a starting URL. The recording can be terminated when the participant reaches a validation condition.

Validation criteria includes time taken to complete a given action, ending up at a particular URL (or class of URLs), based upon question answers, or any combination thereof. These criteria can be classified as either a successful completion of the study, or a failed attempt. Additionally, the validation criteria can also include a decision by the participant to abandon the study.

Abstract: In one embodiment, an architecture for redundant control of wireless devices (e.g., wireless light fixtures, wireless light strips, wireless window shades, or other wireless devices) of a home automation system is provided that uses a combination of WLAN and WPAN communication. During normal operation of the home automation system, control commands generated in response to user input in a control application (app) on a control device (e.g., a remote control, mobile device, or other electronic device) are transmitted via a WLAN (e.g., Wi-Fi) to a bridge device (e.g., a lamp module or wireless keypad) proximate to the wireless device, which forwards the commands over a WPAN (e.g., BLE) to the wireless device. In the absence of an available WLAN connection (e.g., due to failure, prior to its configuration, etc.), the control device may send control commands via the WPAN (e.g., BLE) directly to the wireless device.

Abstract: Management of web conference assets in a content management system. At the conclusion of a web conferencing session, an event is raised at the content management system. Various web conference assets (e.g., recordings) and web conference parameters are analyzed in conjunction with content management system metadata. Based on the analysis, one or more actions to perform on the web conference assets are determined. The content management system metadata may include user profile information of at least one web conference participant. Rules and/or a classification model that considers then-current conditions at the content management system are used singly, or in combination, to determine action characteristics and/or labels such as a retention period or security classifications to apply to the web conference assets. The web conference assets are stored in a hierarchical directory at the content management system. The hierarchy of the directory is derived from aspects of the web conferencing facility.
