Abstract: An embodiment of the invention introduces a method for deploying clustered servers, executed by a processing unit of a DHCP (Dynamic Host Configuration Protocol) server, which contains at least the following steps. Deployment information associated with a requesting server is encapsulated into an acknowledgement after the DHCP server receives a request from the requesting server, where the request requests an IP (Internet Protocol) address, which has been assigned by the DHCP server. The acknowledgement is replied to the requesting server, thereby enabling the requesting server to configure itself as a master server or a slave server in a cloud computing environment according to the deployment information of the acknowledgement.

Abstract: Methods and systems for implementing strict queue ordering in a distributed system are disclosed. A plurality of messages are distributed to a plurality of queue servers based on strict order parameters for the messages. Messages that share a strict order parameter are distributed to a respective one of the queue servers. Sequence identifiers are assigned to the plurality of messages at the queue servers. Each sequence identifier indicates a respective position in a message sequence for a corresponding one of the strict order parameters. The respective position is based on a time of receipt at the queue server. The plurality of messages are enqueued based on the sequence identifiers.

A request is transmitted to a user device having the user account through the data transmission module. The robot account is determined being added to a user contact list. The instant message software robot is controlled to perform an instant message communication with the user device through the data transmission device according to the account pair relation.

Abstract: A method for data transfer includes receiving in an operating system of a host computer an instruction initiated by a user application running on the host processor identifying a page of virtual memory of the host computer that is to be used in receiving data in a message that is to be transmitted over a network to the host computer but has not yet been received by the host computer. In response to the instruction, the page is loaded into the memory, and upon receiving the message, the data are written to the loaded page.

Abstract: A computer receives a request from a client application for data within an enterprise grid. The computer sends the data along with a program to monitor the application's use of the data. The computer subsequently receives from the program a subset of the data being utilized by the client application. Responsive to a subsequent request for the data, the computer sends to the client application only the data corresponding to the identified subset of data being utilized.

Abstract: An application combines on-site and cloud-based calculations. The application selects a cloud computing broker from a list sorted by load. The broker receives computation requests from the application, sends corresponding load-balanced requests to local application service hosts and cloud proxies, receives responses, and sends the responses to the application without identifying the response source as local versus non-local. Each proxy has a logical-physical mapping of cloud-resident worker nodes. A scheduler receives session requests from applications, allocates local and cloud computing resources to a session, and tracks resource usage by session. An application previously run only on-premises can be executed partially on cloud worker nodes without modification. The proxy re-routes unfulfilled requests from a failed worker, undetected by the broker. If all workers assigned to that proxy fail, then the broker reassigns unfulfilled requests to another proxy, undetected by the application.

Abstract: A system and method for managing content data transfers in a peer-to-peer communications network is described. The system includes a hierarchical arrangement of tracker modules, each tracker module being responsible for managing a tracker domain of network elements. Each tracker module has stored therein a content table including a record of content data available to the network elements within its respective tracker domain. Each tracker module responsible for a tracker domain containing end user peers is configured so that, if a content data request is received from a requesting peer in its respective tracker domain and the requested content is held by other peers in that tracker domain, a list of peers having the content data stored thereon is sent to the requesting peer. If the requested content is not held by enough other peers in that tracker domain, the content data request is transferred to the next tracker module up in the hierarchy.

Abstract: Methods and systems for implementing trace deduplication are disclosed. One or more interactions between a plurality of components are determined. The interactions relate to a trace.

The trace is stored if the fingerprint does not match any of the plurality of stored fingerprints. The trace is determined to be a duplicate if the fingerprint matches one of the plurality of stored fingerprints.

Abstract: A non-transitory computer readable medium storing instructions which, when executed on one or more processors, cause performance of operations.

Abstract: Described herein are systems, mediums, and methods for detecting blockage of network traffic at a network server. A signal representative of time series data associated with network traffic is received at a processor for analysis. A data segmentation algorithm and an anomaly detection algorithm are applied in series to the received data. The segmentation algorithm detects regime shifts in the data. Data between regime shifts is considered a segment of data. The anomaly detection algorithm analyzes each segment individually to determine whether anomalies exist in the segment. If a cyclic pattern is found in the segment, the cyclic pattern is extracted from the segment leaving a residual data for analysis. A probability distribution of the residual data is determined for analysis. When an anomaly is detected in the segment o based on the probability distribution of the residual data, it is determined that blockage has occurred on the network traffic.

Abstract: The disclosed embodiments disclose techniques that facilitate the recovery of a virtual machine using a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem in a local storage pool. During operation, a host server executes program instructions for an application in a virtual machine (VM); data associated with this application and/or this virtual machine is stored in the distributed filesystem. Upon detecting a subsequent failure, the system can recover and resume the execution of the virtual machine and application using the previous application and virtual machine data that was stored in the distributed filesystem.
