Abstract:
1. A method for measuring data loss of a data flow transmitted through a communication network, said method comprising: a) at a transmitting node, marking each data unit of said data flow by setting a feature of said data unit to one of a first value or a second value for dividing said data flow in blocks so that data units belonging to a same block have said feature with a same value, and data units belonging to contiguous blocks have said feature with different values; b) at said transmitting node, transmitting said data flow to a receiving node, said transmitting comprising increasing a first counter when a data unit having said feature set to said first value is transmitted, and increasing a second counter when a data unit having said feature set to said second value is transmitted; c) at said receiving node, for each received data unit of said data flow, checking said feature of said received data unit, increasing a third counter when said feature is equal to said first value, and increasing a fourth counter when said feature is equal to said second value; and d) while said steps a), b) and c) are performed, at a management server cooperating with said communication network detecting values of said first counter, said second counter, said third counter and said fourth counter, and calculating a data loss value based on detected values of said first counter, said second counter, said third counter and said fourth counter.
