Patent ID: 7113986

Claim:
A method of determining whether to accept a proposed session in an information system server, the method comprising: generating a session representation that represents the proposed session; wherein the session representation includes a first plurality of parameters; wherein the first plurality of parameters define a proposed additional load of the proposed session on the information system server; determining a current state of the information system server; generating a load representation that represents the current state of the information system; wherein the load representation includes a second plurality of parameters; wherein the second plurality of parameters define a current load on the information system server at a time instant; determining a headroom representation based on the load representation and a model surface; wherein the headroom representation reflects a distance between the model surface and the current load on the information system server; wherein the model surface indicates a capacity of the information system server; determining whether to accept the proposed session in the information system server based on a comparison between a magnitude of the headroom representation and a magnitude of the session representation.
