ABSTRACT:
A method for the measurement of performance parameters of an asynchronous transfer mode transmission network having an asynchronous transfer mode channel, the method including: generating identifiable measurement cells and inserting the identifiable measurement cells into an asynchronous incident flow transmitted by the asynchronous transfer mode channel; receiving an asynchronous flow of cells from the channel, counting a total number of cells received in the asynchronous flow, detecting the identifiable measurement cells among the asynchronous flow and counting a total number of identifiable measurement cells received in the asynchronous flow, comparing a content of each individual identifiable measurement cell with an expected content for that individual identifiable measurement cell so as to detect transmission errors, generating and memorizing a counting information element upon each reception of a given number of cells in the asynchronous flow, the counting information element comprising the total number of cells received in the asynchronous flow, and generating and memorizing an information element upon the reception whenever the content of each individual identifiable measurement cell does not correspond to the expected content for that individual identifiable measurement cell, the information element comprising the total number of cells received in the asynchronous flow, the total number of identifiable measurement cells received in the asynchronous flow, the content of that individual identifiable measurement cell and a number of errors declared.
