The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read / write accesses (I / Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I / O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I / O streams is used to apply controls to guarantee quality of service to all I / O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I / O stream is created that will always be applied to that I / O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I / O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.

A method, system and program product for quantifying a risk of an expected unserved energy in an energy generation system using a digital simulation. An energy load demand forecast is generated based at least in part on a weather year model. A plurality of energy generation resources are committed to meet the energy load demand. An operating status is determined for each committed energy generation resource in the energy generation system. A determination is made as to whether or not the committed resources are sufficient to meet the energy load demand. A dispatch order for a plurality of additional energy resources is selected if the committed resources are not sufficient to meet the energy load demand. Additional resources are committed based on the selected dispatch order until the energy load demand is met. The expected unserved energy is determined and an equivalent amount of energy load demand is shed based at least in part on an expected duration of unserved energy and a customer class grouping. An associated cost for the expected unserved energy is also determined.

Methods and systems for optimizing server polling by a mobile client are described, thereby allowing mobile terminals to conserve battery life by more efficiently using resources such as the processor and transceiver in the mobile terminal A broker system may be used to minimize wireless communication traffic used for polling. A broker stub intercepts server polling messages at the client, multiplexes the sever requests together, and forwards the multiplexed message to a broker skeleton that de-multiplexes and forwards the messages as appropriate. Polling may also be dynamically adapted based on user behavior, or a server guard may be used to monitor changes to data, and notify a client to poll its respective server when the server guard detects new or updated data on that server for that client.

The present invention relates to a method for a random access process in a mobile communication system. According to the exemplary embodiments, in the case where a mobile terminal requests a random access to a network, when the network is not able to promptly allocate a resource for the random access to the mobile terminal due to an insufficient resource, the mobile terminal is maintained in a standby state without repeatedly requesting the random access to the network. Accordingly, it is possible to reduce the uplink signal interference caused by the repeated random access request, reduce the possibility of communication contention between the mobile terminals for the access to the mobile communication system, and reduce the power consumption of the mobile terminal.

When large numbers of children play in a playground, part of the power of their play could be usefully harnessed resulting in large energy storage. This stored energy can then be converted for basic, low-power, applications in the school such as lighting, communication, or operating fans. Energy can be produced through the use of pneumatic (i.e., compressed air) systems such as cylinders, motors, valves, and regulators for the conversion of human power of children's play in school playgrounds and other public places. The energy of the compressed air can then be converted to electricity for purposes such as lighting and communication. This provides a low-cost, low-resource means of generation of electricity, especially for use in developing countries.

The invention provides a message forwarding method and a device applied to an SDN. According to the technical scheme of the invention, an SDN controller issues the flow entry of each VM to a physical gateway with the VTEP instead of the VM as a unit, wherein the MAC address in the issued flow entry is the aggregated MAC address of an MAC address pool allocated to the VTEP instead of the real MAC address of the VM. When an MAC forwarding table entry is generated by the physical gateway based on flow entries, a single MAC forwarding table entry is generated based on N (larger than one) flow entries. That means, for the above N flow entries, only one MAC forwarding table entry is stored in the hardware table entry resource of the physical gateway. Therefore, the hardware table entry resource of the physical gateway is saved. The defect that the hardware table entry resource of the physical gateway is insufficient can be overcome.
