Patent number: 11632330Abstract: A method may include determining whether the topology of a network includes a direct path between a first endpoint and a second endpoint in the network. A direct path may be used to send a first type of traffic from the first endpoint to the second endpoint whereas any currently available path may be used to send a second type of traffic from the first endpoint to the second endpoint. If the topology of the network does not include a direct path, the first type of traffic may be buffered at the first endpoint until the topology of the network is reconfigured to include the direct path. The topology of the network may be reconfigured when at least one switch in the network reconfigures, for example, by switching from one interconnection to another interconnection pattern. Related systems and articles of manufacture are also provided.Type: GrantFiled: January 31, 2019Date of Patent: April 18, 2023Assignee: The Regents of the University of CaliforniaInventors: William Mellette, Alex Snoeren, George Porter, George Papen

Patent number: 11368336Abstract: An apparatus for interfacing with a circuit switched network may be configured to detect when a data carrier signal from a circuit switched network is offline. While the data carrier signal from the circuit switched network is offline, the apparatus may send, to a network element coupled with the circuit switched network via the apparatus, control packets indicating that the data carrier signal is offline. The apparatus may further maintain an active data carrier signal between the apparatus and the network device by sending, to the network element, protocol idle frames. The apparatus may buffer, at the apparatus, packets sent from the network element to the circuit switched network. Once the data carrier signal is restored, the apparatus may send, to the circuit switched network, control packets indicating that the data carrier signal is online and the packet buffered at the apparatus while the data carrier signal is offline.Type: GrantFiled: July 10, 2018Date of Patent: June 21, 2022Assignee: The Regents of the University of CaliforniaInventors: George Porter, William Mellette

Publication number: 20110161294Abstract: The disclosed embodiments provide a system that determines whether to dynamically replicate data segments on a node in a computing cluster that stores a collection of data segments. During operation, the system identifies a data segment from the collection that is predicted to be frequently accessed by future tasks executing in the cluster. The system then determines a slowdown that would result for the current workload of the node if the data segment were to be replicated to the node. The system also determines a predicted future benefit that would be associated with replicating the data segment to the node. If the predicted slowdown is less than the predicted future benefit, the replication system replicates the data segment to the node.Type: ApplicationFiled: December 30, 2009Publication date: June 30, 2011Applicant: SUN MICROSYSTEMS, INC.Inventors: David Vengerov, George Porter
