Patent ID: 8289857

Claim:
A method for determining a data transport unit parameter for communication between two stations in a network of stations, wherein for the data transport unit parameter, a number of common values exists and for a communication path between the two stations, an optimum value of the data transport unit parameter exists depending on the communication technology or network equipment configuration used, the method comprising the steps of: sending a plurality of pairs of probe data transport units to a partner station, for each pair, a first data transport unit parameter being from the set of common values for the data transport unit parameter and a second data transport unit parameter being the first data transport unit parameter increased by a minimum possible increment, and sending each of said plurality of pairs of probe data transport units without waiting for a response message corresponding to the previous pair of probe transport units; evaluating, in a processor, corresponding response messages from the partner station to determine the range between two values from the set of common values in which the optimum value exists; performing a grid search in the determined range, wherein the probe data transport unit parameters for the grid search are sent with a fixed size interval, hereinafter called grid width, the data transport units being sent without waiting for the response message corresponding to the previous grid search probe data transport unit to be received, and in which a grid cell in which the optimum value of the data transport unit parameter lies is determined by evaluating response messages for the probe data transport units sent during the grid search.
