A method, system and computer program product for providing a service to multiple tenants of an application. Responsive to receiving from a client of a tenant a request, a tenant context of the tenant is bound to the request. With respect to an access to an isolation point of the application in the request, the access to the isolation point is redirected to a partition based on the tenant context bound to the request. The partition may be pre-established for the tenant with respect to the application. Hence, it is possible to provide a multi-tenant solution in a convenient, fast, and cost-effective way, and, in turn, to achieve resource sharing to a greater extent and enhance the resource efficiency.

There is provided a mechanism for allocating communication resources of a cellular communication network to a D2D communication. After an eNB has configured a number of resource pools indicating a set of resources usable in the D2D communication, D2D clusters which share a same resource pool are enabled to obtain resources for their respective D2D communication. By detecting the current resource utilization state in the allocated resource pool by measurement on the UE side, it is decided whether suitable resources are available or not. An overload situation is signalled to the eNB if no suitable resource can be detected.

This invention is to enable appropriate routing based on transition prediction of network traffic. This routing control method includes: reading out predicted utilization transition data (e.g. utilization rate, or utilized bandwidth) associated with a received connection set-up request from a predicted utilization transition data storage storing said predicted utilization transition data for each resource (e.g. links between routers, or server) in a network in future; and selecting a resource satisfying a predetermined condition based on the read predicted utilization transition data. Thus, by using said predicted utilization transition data, an appropriate resource is identified in accordance with future time transition of the resource utilization rate, for example, and thereby, appropriate routing is possible. For example, when a link that a traffic volume will increase after a predetermined time exists, it is possible to judge that such a link is not used even when there are a lot of available bandwidths now.

A filter monitoring system employs a differential pressure sensor to provide a continuous signal output proportional to a pressure drop across a filter element. The differential pressure sensor communicates with a controller that provides output signals to indicate that the filter requires replacement and provides advanced warning for when the filter element will reach a predicted filter differential pressure limit value.

A filter executing on a processor monitors instructions executing on the processor to identify instructions that will benefit from performance tuning. Filtering instructions before analysis for performance tuning reduces overhead by identifying candidates for performance tuning with low cost monitoring before expending resources on analysis so that only instructions that will have performance tuning are analyzed. Reducing overhead for performance tuning makes performance tuning practical in a dynamic optimization environment in which instructions and their effective addresses change over time.
