1. A method of accepting a session in an information system server, the method comprising:

  • generating a representation of a session, based on one or more of a typical feature vector, regression models, piecewise linear or non-linear models for the session, the representation of the session including a first plurality of parameters, the first plurality of parameters defining a proposed additional load of the session on the information system server;

    determining a current state of the session representation of the information system server, the current state of the information system defined by a second plurality of parameters, the current state session representation defining a current load on the information system server at a time instant;

    determining a headroom representation for the current state of the information system, the headroom representation defined by a distance between a model surface, the model surface indicating a capacity of the information system server;

    comparing a magnitude of the headroom representation to a magnitude of the session representation.
