US 2011/0255440 A1 · Measurement of Data Loss in a Communication Network

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.

Dependent claims

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 and 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, increasing a first counter when said feature is set to said first value, and increasing a second counter when said feature is set to said second value;
c) transmitting said data flow to a receiving node;
d) at said receiving node, for each data unit of said data flow, checking said feature, 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
e) calculating a data loss value based on detected values of said first counter, said second counter, said third counter and said fourth counter.

3 more elements

A communication network comprising a transmitting node, a receiving node and a management server for cooperating with said communication network, wherein said transmitting node is configured to:

a) mark each data unit of said data flow by setting a feature of said data unit to one of a first value and 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) increase a first counter when said feature is set to said first value, and increase a second counter when said feature is set to said second value;
and
c) transmit said data flow to a receiving node,
wherein said receiving node is configured to:
d) for each data unit of said data flow, check said feature, increase a third counter when said feature is equal to said first value, and increase a fourth counter when said feature is equal to said second value;
and
wherein said management server is configured to:
e) calculate a data loss value based on detected values of said first counter, said second counter, said third counter and said fourth counter.
