Abstract: A system and method is provided for integrating the front-end and back-end of a virtualized desktop environment to achieve an objective. Network measurements are gathered which are related to enforcement of an objective. Based on gathered network measurements and quality of service requirements for user sessions, a determination is made as to how back-resources and front-end remoting protocol settings are to be adjusted. The back-end resources and the front-end remoting protocol settings are controlled to achieve the objective.

Abstract: A method monitors machine activity of multiple virtual computing devices operating through at least one physical computing device by running a monitoring agent. The monitoring agent monitors performance of the multiple virtual computing devices. The method measures simple operating characteristics of only a base level virtual computing device. The method monitors complex operating characteristics using the monitoring agent by: measuring the complex operating characteristics for each of the multiple virtual computing devices (using each of the multiple virtual computing devices); recording the complex operating characteristics of each of the multiple virtual computing devices on a corresponding memory page of each of the multiple virtual computing devices; and sharing each the corresponding memory page with the base level virtual computing device through an interdomain communications channels to transfer the complex operating characteristics to the monitoring agent. The method identifies simple events and complex events for each of the multiple virtual computing devices by evaluating the simple operating characteristics and the complex operating characteristics and outputs the simple events and the complex events for each of the multiple virtual computing devices.

Abstract: A method of estimating a transit demand graph includes collecting conditional information that includes at least one condition that when satisfied converts at least one non-rider into a rider, generating a non-rider transit demand graph by satisfying one of the conditions, and generating a normalized transit demand graph from the non-rider transit demand graph and a rider transit demand graph. The riders use public transit and the non-riders do not use public transit. The non-rider transit demand graph shows the demand of the non-riders for a public transit route. The rider transit demand graph shows the demand of riders for the same public transit route.

Abstract: Embodiments of the present invention relate to an approach for suggesting/recommending migration of an IT environment to a cloud computing infrastructure. Specifically, in a typical embodiment, historical incident data of an information technology (IT) environment is analyzed. Based on the historical incident data, it may be determined whether a problem is recurring in the IT environment. If so, it may then be determined whether the problem can be mitigated in the cloud computing infrastructure. For example, it may be determined whether the cost of mitigating the problem by migrating to the cloud computing infrastructure is less than the cost of loss due to the problem within the current IT environment. A report particular to the IT environment that identifies a benefit of migrating the IT environment to the cloud computing infrastructure may be generated.

Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.
