Optical burst exchange route choosing method based on resource forecast

This invention discloses one optical burst exchange route selecting method based on materials predicting, which comprises the following steps: reading one degree joint three status of transmission distance L1, updated circle T1, wavelength busy degree P1 and occupancy information W1; reading the send degree joint relative three status and bringing each parameter to the linear or non-linear information prediction module to compute out relative joint status information reliable amending factorªŠ to compute out joint instant materials information; If w is zero then amending 0+ªŠ as 1-ªŠ to use one degree joint instant materials signal subject to form matrix A and the second degree joint instant information to form subject matrix B and computing Qú¢Aí‡Bíõto select largest Q value as burst transmission reliable path.
