Abstract: An improved technique involves avoiding congestion in a network by monitoring round trip times of data units sent from a node of the network. Along these lines, a controller at a node of the network sends data units at some transmission rate to a target node with instructions to send a response back to the home node. Upon receiving the response, the controller measures the round-trip time as the difference in time from sending of the message to receipt of the response. Based on the round-trip time, the controller sets a new transmission rate at which to send units of data.

A physical-layer device receives the data from the memory and transmits the data from the first network device to a second network device.

Abstract: A storage system that is configured to fairly service requests from different host systems particularly in congested situations. To balance the processing of tasks between different clients, the system sorts tasks received from different clients into task lists. In particular, the system sorts the incoming tasks based on the ITL (Initiator, Target, LU) nexus information associated with each task. In some instances, a new task list is created for each ITL nexus. The sorting of tasks may provide for a more even distribution of tasks and thus a more fair processing of tasks. More specifically, because tasks from each list are processed in round-robin fashion, tasks arriving from even the slowest clients are given a substantially equal chance of being processed as the tasks arriving from the faster clients.

Abstract: Techniques are described herein for capturing and restoring database session state. Production database server components save the session state of each of a plurality of database sessions. The components store workload units that are processed in these sessions. The components store updated session states in response to certain events. Thus, the components may capture multiple session states, pertaining to various different points in time, for each session.

A user selects, from among the time points represented by the session states, a point in time at which the user would like workload replay to begin. Sessions are re-created on the test database server. Session states of these sessions are set to reflect the session states as they existed at the user-selected time point. Workload units are replayed in the sessions relative to the test database server.

Abstract: Emulating a NIC for packet transmission on hardware RSS unaware NICs in a multi-core system enables each of a plurality of slave packet engines to emulate a NIC for packet transmissions locally even though the actual NIC transmissions from the queue are handled by a master packet engine only. Each slave packet engine treats a local software-implemented transmission queue as a device queue and uses the local queue to keep track of status of data from the packet engine in the device output queue, handled by the master packet engine on behalf of the slave packet engines. As the master packet engine transmits the data from the queue and the status of the queue changes, the master packet engine and the slave packet engines may use pointers to keep track of which data packets are transmitted, which data packets are drained and which data packets are still in the queue.

Abstract: An approach for caching potentially repetitive message data in a publication/subscription messaging environment is provided. Specifically, when a message is received on a broker system from a publisher system, the broker system analyzes the message for potentially repetitive data. Once such a set of data has been identified, a unique identifier/key corresponding thereto will be sent back to the publisher system and the set of data will be stored in a (data) cache. Upon receipt, the publisher system will cache/store the unique identifier in a (key) cache. Then, when the publisher system generates a future message that would contain the same set of data, the publisher system will substitute the unique identifier (as retrieved from the key cache) for the set of data to yield an abbreviated/truncated message.
