The second storage node may cache a copy of the requested data object, and may service at least a portion of requests for the data object using the cached copy.

Abstract: System and methods are described for providing adaptive routing in the presence of persistent flows. Switches in a fabric have the capability to establish flow channels. Switches can adaptively route flows, while monitoring transmission characteristics of the flows channels to identify whether any flows are experiencing congestion towards a destination. In response to detecting congestion, it can be further determined whether the flow is related to a source of congestion, or alternative the flow is a victim of congestion. Flows that are a source of congestion have their routing constrained to prevent congestion from propagating. For example, new packets of a flow that is a source of congestion may be forced to only take the path of the data transmission that detected said congestion (preventing congestion from spreading). Alternatively, victims of congestion do not have their routing constrained, and packets can take any path as permitted by adaptive routing.

Abstract: A SCADA web HMI system dynamically distributes server connection priority lists from web HMI servers to HMI clients in accordance with order of assignment which takes load balancing into account. As a result, preliminary settings associated with connection priority do not need to be made on the HMI clients.

The SCADA web HMI system can reduce the operating costs necessary in client settings while ensuring redundancy and load balancing of servers.

Abstract: Embodiments for optimizing a cost of storing backup data in an object store of a public cloud network provided by a cloud provider by storing delta objects each embodying changes to blocks of the backup data between a full backup incremental backups. The delta objects are each of a same block size, which can be changed.

The process selects a block size for the delta objects based on a lowest calculated cost.
