    2727Let us consider an example of "!FrameLength" metric for illustration purposes below.

    96 === 2.5 Add measurement tasks with the custom metric ===
     96=== Step-5: Add measurement tasks with the custom metric ===
    9797From Researcher Web-portal (!OnTimeBeacon):
    9898The custom metric will appear in the "Measurement Request Specification" page to add related measurement tasks.

    194194To see this experiment case study of !OnTimeMeasure in action, please see [http://ontime.oar.net/demo/framelength.htm demo video]. The experiment uses !OnTimeMeasure to measure all links delay across inter and intra federated sites periodically using Ping tool, and measures "!FrameLength" of http requests across all links using Tshark periodically. The measurement results are compared and studied with various other aspects of data from the experiment application. To accomplish these measurements with !OnTimeMeasure, the !RootBeacon is installed on an extra node in the experiment slice, and !NodeBeacons are installed on nodes f1, bl1, be1, fe2 and bl2 within the experiment slice.

     196== 4.2 Case Study 2: Resource allocation in Virtual Desktop Clouds ==
    197197
    198198A GENI experiment being led by The Ohio State University aims to develop utility-directed resource allocation schemes within virtual desktop clouds (VDCs). The schemes allocate resources (i.e., CPU, memory, network bandwidth) such that the global utility (i.e., combined utility of all virtual desktops at a data center) is maximized under the constraint that each virtual desktop at least meets it minimum quality requirement specified in service level agreements. The allocation adaptation is based on feedback of network health from the client, and CPU/memory load on the server.
