Abstract
A method for measuring data loss of a data flow in a communication network is provided. The method includes, at a transmitting node: marking each data unit of the data flow for dividing the data flow in blocks so that: data units of a same block have a feature with a same value, while data units of contiguous blocks have the feature with different values; increasing a first counter when the feature has the first value, and a second counter when the feature has the second value; and transmitting the data flow to a receiving node. The method includes, at the receiving node, for each data unit: checking the feature, increasing a third counter when the feature has the first value, and increasing a second counter when the feature has the second value. The method includes calculating data loss based on detected values of first, second, third and fourth counters.
