Abstract

The simulator is provided with a control section that gathers the parameters of a plurality of parts in a computer network and that thereby predicts a future state of the computer network over a prescribed period of time. Further, a scenario creation/management creates a model corresponding to the computer network. Finally, simulation engine executes the simulation on the basis of the created model.

Claims

1. A simulator comprising:

a parameter gathering unit that gathers parameters from a plurality of portions in a network;

a future prediction unit that according to the parameters gathered by said parameter gathering unit predicts a future state in said network over a prescribed length of time;

a model creation unit that creates a model corresponding to said network;

a parameter application unit that applies the parameters gathered by said parameter gathering unit to the model created by said model creation unit; and

a simulation unit that executes simulation according to the model created by said model creation unit.

2. The simulator according to

claim 1

further comprising a display unit that displays the result of prediction by said future prediction unit and the result of simulation by said simulation unit.

3. The simulator according to

claim 1

,

wherein said parameter gathering unit gathers the parameters corresponding to a plurality of segment pairs in said network;

and

wherein said future prediction unit predicts the future state over a prescribed length of time in corresponding relationship to a plurality of the segment pairs.

4. The simulator according to

claim 3

,

wherein said display unit displays the result of prediction by said future prediction unit and the result of simulation by said simulation unit in such a way that these results correspond to the segment pairs.

5. The simulator according to

claim 2

,

wherein said display unit displays whether the result of simulation by said simulation unit satisfies the performance standard of said network that has been set by a user beforehand.

6. A simulation method comprising the steps of:

gathering parameters from a plurality of portions in a network;

predicting a future state in said network over a prescribed length of time based on the gathered parameters;

creating a model corresponding to said network;

applying the gathered parameters to the created model; and

executing simulation based on the created model.

7. The simulation method according to

claim 6

, further comprising a step of displaying the result of prediction and the result of simulation.

8. The simulation method according to

claim 6

,

wherein parameters are gathered corresponding to a plurality of segment pairs in said network;

and

the future state is predicted over a prescribed length of time in corresponding relationship to a plurality of the segment pairs.

9. The simulation method according to

claim 7

,

wherein the result of prediction and the result of simulation are displayed in such a way that these results correspond to the segment pairs.

10. A computer readable medium for storing instructions, which when executed on a computer, causes the computer to perform the steps of:

gathering parameters from a plurality of portions in a network;

predicting a future state in said network over a prescribed length of time based on the gathered parameters;

creating a model corresponding to said network;

applying the gathered parameters to the created model; and

executing simulation based on the created model.
