    2015There are two alternative methods for the user to implement this ''interface'' between their experimental applications and the OML Collection Clients. These two alternative methods are:
    2116
    22  * Method based on dynamic OML client library
     17 * '''Method based on dynamic OML client library''' [[BR]] This method is the appropriate one for experimenters who write their own experimental application in C or C++.
     18
     19 * '''Method based on OML client daemon''' [[BR]] This method is the appropriate one for experimenters who use existing applciations with no access to their source code, or who develop their own experimental applications in another language than C/C++. [[BR]] '''-- NOTE:''' this method is currently under development, and will be available soon '''--'''

     26This method assumes that the experimenter is developing its own experimental application(s) in C or C++. This method is illustrated in figure 2.

    31 The details and "How-To" of such association will be presented in a following part of this tutorial. In the context of this introduction to the testbed, the client-side measurement collection can be viewed as follows. The application will forward any required measurements or outputs to the OML collection client. This OML client will optionally apply some filter/processing to these measurements/outputs, and then sends them to the OML Collection Server (currently over one multicast channel per experiment for logical segregation of data and for scalability)

    3534, and, as such, has a client application programming interface (API).  A developer can use this client API through a web interface to define the measurement points and parameters for his or her application.  Measurement points and their frequency of collection are an important part of ones experimental plan.
