Abstract: Database replication is performed by tracking sequence numbers associated with binary change logs. At a producer cluster, a binary change log is generated based on a write transaction made to a database partition in the producer cluster. Included with the binary change log is a sequence number corresponding to the write transaction. The binary change log is transmitted from the producer cluster to a consumer cluster, where a determination is made whether to apply the binary change log based on the included sequence number. The binary change log is then applied to a database partition in the consumer cluster. The sequence number is stored at the consumer cluster by combining the sequence number with a numerical range having a first number and a second number, where the second number has a value corresponding to the most recent binary change log applied to the database partition in the consumer cluster.

Abstract: A method for controlling a vapor compression system determines a value of a metric of performance of the vapor compression system using a previous value of an estimated parameter and a previous value of a control signal determined for a previous time step of the control. The values of the estimated parameter represent a relationship between values of the control signal and values of the metric of performance. A current value of the estimated parameter is determined based on the previous value of the estimated parameter and an error between the determined value of the metric of performance and a measured value of the metric of performance. Next, a current value of the control signal is determined based on the current value of the estimated parameter.

Abstract: A quality of service for various classes of services for the transfer of electronic data packets is provided by establishing classes of packets for a customer and for assigning bandwidths to the classes for the customer. Accordingly, the amount of bandwidth for one type of service may vary from the bandwidth for another type of service over the same data connection. A device, such as an edge router of a network, may police the data packets being transferred by a customer to maintain the bandwidth being utilized by a given class of packets of the customer to within the assigned bandwidth for that class of the customer. The data packets may further be policed by core routers of the network may also to maintain the bandwidth being utilized by a given class of packets to within the assigned bandwidth for that class as specified by the service provider.

Abstract: Forwarding packets using experimental bits to support service provider applications. An incoming packet is received. If the packet is associated with a service hosted by a service provider, the packet is forwarded using a packet marking associated with a predefined forwarding behavior applicable to the service hosted by the service provider. If the packet is not associated with a service hosted by the service provider, the packet is forwarded using a label marking associated with the packet.

Abstract: Managing the bandwidth capacity of a network that includes a plurality of traffic destinations, a plurality of nodes, and a plurality of node-to-node links. For each of a plurality of traffic classes including at least a higher priority class and a lower priority class, an amount of traffic sent to each of the plurality of traffic destinations is determined. One or more nodes are disabled, or one or more node-to-node links are disabled. For each of the plurality of traffic classes, a corresponding traffic route to each of the plurality of traffic destinations and not including the one or more disabled nodes or disabled node-to-node links is determined. Bandwidth capacities for each of the corresponding traffic routes are determined to ascertain whether or not sufficient bandwidth capacity is available to route each of the plurality of traffic classes to each of the plurality of traffic destinations.
