FIELD: information technology.
SUBSTANCE: invention relates to backbone network monitoring. Generation of the first operation, administration and maintenance (OAM) message for quality of service control from the local network terminal station to the peer-to-peer network terminal are provided; aggregating a first OAM message with a first IP service message for transmitting service information from a local network terminal station to a peer-to-peer network endpoint; and sending the first aggregated message generated from the aggregation to the peer-to-peer network end station. First aggregated message is used by a terminal station of a peer-to-peer network to determine quality of service from a terminal station of a local network to a terminal station of a peer-to-peer network.
EFFECT: high accuracy of monitoring without considering the state of the backbone network.
