The method may comprise obtaining a character of first-direction communications and a character of second-direction communications in a network environment, the first-direction communications being network communications from a first node to a second node, and the second-direction communications being network communications from the second node to the first node. The method may further comprise determining a dependency between the first node and the second node based on the character of first-direction communications and the character of second-direction communications, the dependency between the first node and the second node indicating whether the first node depends on the second node or the second node depends on the first node.

Abstract: A computer system for optimizing bandwidth usage within a cloud storage system identifies distinct requests to access a particular digital file. When the number of requests exceeds a threshold, the computer system queries a remote directory server for the particular digital file. The query system then receives, from the remote directory server, addresses to data blocks stored within multiple remote storage nodes. The system requests at least a portion of the addressed data blocks. Upon receiving the blocks, the system decodes the particular digital file from the portion of the addressed data blocks. The computer system then stores the decoded digital file within local memory and communicates the local-area network address to the remote directory server.

The method may further include evaluating feedback data resulting from the test to decide whether a change is necessitated for the default configuration, and computing a new configuration to replace the default configuration at the computing device, if the change is necessitated for the default configuration.

Abstract: A method for buffering data in an adaptive streaming service according to an embodiment of the present disclosure comprises the steps of: measuring a per-session throughput and an available bandwidth with respect to traffic generated from a streaming application; determining a number of multiple sessions based on the per-session throughput and the available bandwidth; determining a buffer size for pre-storing data based on a cache hit ratio of the streaming application; and generating at least one request message requesting data based on the number of multiple sessions and the buffer size, and transmitting the at least one request message to a server.

Abstract: The embodiments herein provide a fair, high speed and lightweight consensus mechanism for leader election in distributed systems using coupons. The consensus mechanism uses a leader election mechanism that is randomized in twin dimensions of space and time using the concept of a colliding random walk. A source node is enabled to generate left and right coupons in a quantum resistant manner for random walks. Two novel coupon processing mechanisms called Process Execution Time Synchronization (PETS) mechanism and Single Queue (SQ) mechanism are used to process the coupons and find matches. The use of PETS optimizes memory and time requirements while SQ is extremely fast and efficient to handle large volumes of coupons. Also, the coupon forwarding to neighbouring nodes is performed based on three algorithms namely Uniform, Delay and Adaptive Delay forward. These forwarding algorithms effect high fairness even in case of open networks.

Abstract: A system and method for generating a data set structured for recognition of time series data by a machine learning computer are provided. The method includes acquiring time series data, generating tensor units based on the time series data, and identifying a target tensor unit including a time of failure of a mainframe computer system.

The computer model is then applied to data in a production environment for identifying a production data pattern corresponding to a data pattern recognized in the tensor sets.

Abstract: Mail server migration. For each mailbox, a migration utility is started on a target server to get a list of message IDs that have already been migrated. The command “listmessage-ids” is executed. The migration utility is started on the source server in a backup mode. The “backup” command is executed. Then, the migration utility is started on the target server in a restore mode. A “restore” command imports the messages. The migration utility on the source server provides mail messages to a standard output. The migration utility on the target server accepts mail messages on the standard input and restores them. RPC agent transfers data via TCP once it gets it from the migration utility on the source server. The migration module receives data from the RPC agent and puts data to the standard input of the migration utility on the target server as soon as it receives it.

Abstract: Technologies are described for dynamic attachment delivery in emails for advanced malicious content filtering. An email service may intercept emails with attachments (or other threats such as links, embedded objects, etc.) and detach the threat (e.g., attachment) from the email allowing the email to be forwarded to the recipient without delay. The threat may be sequestered and analyzed. If the threat is determined to be harmless, it may be reattached to the email and the client notified so they can open the attachment, activate the link, or perform comparable actions.
