Abstract: Techniques for serving a manifest file of an adaptive streaming video include receiving a request for the manifest file from a user device. The video is encoded at different reference bitrates and each encoded reference bitrate is divided into segments to generate video segment files. The manifest file includes an ordered list of universal resource locators (URLs) that reference a set of video segment files encoded at a particular reference bitrate. A source manifest file that indicates the set of video segment files is identified based on the request. An issued manifest file that includes a first URL and a second URL is generated based on the source manifest file. The first URL references a first domain and the second URL references a second domain that is different from the first domain. The issued manifest file is transmitted to the user device as a response to the request.

Abstract: In one embodiment, a method includes detecting a change in network topology and broadcasting a transient unconditional unpruning message to multiple nodes in the network. The message is configured to instruct each of the nodes receiving the message to start a phase timer in response to the broadcast message; unprune its operational ports; and, upon expiration of the phase timer, prune its ports in accordance with the results of a pruning protocol.

Abstract: An API rate limiting system may receive a client request from an API client associated with a tenant, formulate a proxied request with an internal authentication specific to the tenant, and send the proxied request to API endpoints (tenant resources) at a store. The store fulfills the request, accessing and modifying local database(s) as needed, and returns a response to the system. The system returns the response to the API client along with information about the API client's quota for the current time window. The system may calculate the quota based on a resource limit with respect to a number of clients accessing a resource. In some embodiments, the system may implement an exponential distribution function in making a determination on a quota per API client per time window.

Each of these servers includes one or more services. The shared metrics array is accessible by each of the plurality of servers, and includes a set of metrics for each of the plurality of servers. A determination is made based on the set of metrics associated with at least one server in the plurality of servers if a service request is to be sent to the at least one server. The service request is sent to the at least one server based on determining that the service request is to be sent to the at least one sever.

Abstract: A method, system and computer program product for preventing messages from being sent using inappropriate communication accounts. A message created by a user of a mobile device is analyzed to identify the topic and sentiment. The appropriateness of the message being sent to the intended recipient(s) using a selected communication account (e.g., company social media account) is determined based on one or more factors, including the analysis of the message to identify the topic and sentiment. A score is generated as to the appropriateness of sending the message to the intended recipient(s) based on such an analysis. If the score is less than a threshold value, then the message is deemed to not be appropriate to be sent to the intended recipients using the selected communication account. In this manner, potentially erroneous communications, such as accidentally posting a message to a wrong social media account, may be prevented.
