Abstract: A method and associated system. A server computer selects a re-ordering scheme from one or more re-ordering schemes, for re-ordering chunks of an original file. The server computer divides the file into the chunks. After the file is divided into the chunks, the server computer re-orders the chunks according to the selected re-ordering scheme to form an obfuscated file that includes the re-ordered chunks. The server computer sends, to a client computer, the obfuscated file along with a scheme access reference that enables the client computer to access the selected re-ordering scheme.

Abstract: Several embodiments include a live stream system in a media distribution network. The live stream system can divide a broadcast stream from a broadcaster device into one or more media segments. The live stream system can generate an original manifest uniform resource locator (URL) and a duplicate manifest URL to associate with the media segments. The live stream system can generate a broadcast manifest that identifies the media segments via one or more segment identifiers. The live stream system can upload the broadcast manifest and the media segments to a cache system to make the broadcast manifest accessible via either the original manifest URL or the duplicate manifest URL.

Abstract: A device may establish a communication session, with a client device, for monitoring a latency of a service. The device may receive, from the client device, a request for a monitored service list. The monitored service list may identify one or more services for which service latency monitoring is supported. The device may provide, to the client device, the monitored service list. The device may receive, from the client device, a service latency monitoring session request that may identify the service to be monitored. The device may establish, with the client device, the service latency monitoring session based on the service latency monitoring session request. The device may cause the service to be performed. The device may generate information for determining the latency of the service. The device may transmit, to the client device and via the service latency monitoring session, the information for determining the latency of the service.

Abstract: Count tracking in distributed environments is described, for example, as in data centers where many sites receive data and a coordinator node estimates a sum of the data received across the sites. Count tracking may be used in database applications, search engines, social networking applications and others. In various embodiments sites and a coordinator node work together to implement a process for summing data received at sites, where the sum takes into account both increments and decrements. In examples, a site decides whether to notify the coordinator node of a new data item according to a sampling probability that is related to an estimate of the current global sum of the data input across sites. In some examples a multi-mode algorithm is implemented which increases or decreases communication between the sites and the coordinator node according to behavior of the estimated global sum such that communications costs are optimized.

Abstract: A method and apparatus for managing CNAME records such that CNAME records at the root domain are supported while complying with the RFC specification (an IP address is returned for any Address query for the root record). The authoritative DNS infrastructure acts as a DNS resolver where if there is a CNAME at the root record, rather than returning that record directly, a recursive lookup is used to follow the CNAME chain until an A record is located. The address associated with the A record is then returned. This effectively “flattens” the CNAME chain. This complies with the requirements of the DNS specification and is invisible to any service that interacts with the DNS server.

Abstract: A device may be configured to receive a message from a user device; and determine whether the message includes a parameter. When the message does not include the loop indicator parameter, the device may add the loop indicator parameter to the message to generate a first modified message, and output the first modified message toward an intended recipient of the message. When the message includes the loop indicator parameter, the device may determine whether a value of the loop indicator parameter exceeds a threshold value. When the value of the loop indicator parameter does not exceed the threshold value, the device may discard the message. When the value of the loop indicator parameter exceeds the threshold value, the device may modify the value of the loop indicator parameter value to generate a second modified message, and output the second modified message toward the intended recipient of the message.

Abstract: A system and method for addressing the impact of tenant/user customizations on various operations in a multi-tenant computing platform. In one embodiment, the system uses an operating system process (e.g., a parent process) to handle incoming operation requests to the platform from one or more tenants. If an incoming request specifies that a user customization should be executed, then the parent process coordinates execution of a separate operating system process (e.g., a child process) to execute the customization operation and return the result of the child process execution. In this manner, a single parent process may create several child processes to execute different customizations that each may be monitored and managed separately for resource use and consumption.

Abstract: Processing elements in a streaming application may contain one or more optional code modules—i.e., computer-executable code that is executed only if one or more conditions are met. In one embodiment, an optional code module is executed based on evaluating data flow rate between components in the streaming application. As an example, the stream computing application may monitor the incoming data rate between processing elements and select which optional code module to execute based on this rate. For example, if the data rate is high, the stream computing application may choose an optional code module that takes less time to execute. Alternatively, a high data rate may indicate that the incoming data is important; thus, the streaming application may choose an optional code module containing a more rigorous data processing algorithm, even if this algorithm takes more time to execute.
