A method for measuring frame loss on a network connection between a near-device, NED, and a far-end device, FED, during a measurement period, the method comprising: placing, by the NED and on the network connection, a plurality of test frames comprising a first test frame comprising a first unique sequence number and a second test frame comprising a second unique sequence number, wherein the plurality of test frames cause the FED to transmit on the network connection a plurality of reflected test frames back to the NED, wherein the NED and the FED operate without synchronizing local counters in the NED with local counters in the FED, wherein the plurality of reflected test frames comprises a first reflected test frame and a second reflected test frame; wherein the FED comprises a FED receiving counter configured to count the number of the plurality of test frames received by the FED; obtaining, by the NED and from the network connection, the first reflected test frame comprising the first unique sequence number, and a first FED receiving counter value from the FED, wherein the first FED receiving counter value is the value of the FED receiving counter after receiving the first test frame by the FED; obtaining, by the NED and from the network connection, the second reflected test frame comprising the second unique sequence number and a second FED receiving counter value from the FED, wherein the second FED receiving counter value is the value of the FED receiving counter after receiving the second test frame by the FED; extracting, by the NED, the first unique sequence number from the first reflected test frame and the second unique sequence number from the second reflected test frame; calculating, by the NED, a one-way frame loss value from the FED to the NED using the first unique sequence number, the second unique sequence number, the first FED receiving counter value, and the second FED receiving counter value; and determining, by the NED, whether one or more reflected test frames are dropped from the FED to the NED by using the first unique sequence number and the second unique sequence number. placing, by the NED and on the network connection, a plurality of test frames comprising a first test frame comprising a first unique sequence number and a second test frame comprising a second unique sequence number, wherein the plurality of test frames cause the FED to transmit on the network connection a plurality of reflected test frames back to the NED, wherein the NED and the FED operate without synchronizing local counters in the NED with local counters in the FED, wherein the plurality of reflected test frames comprises a first reflected test frame and a second reflected test frame; wherein the FED comprises a FED receiving counter configured to count the number of the plurality of test frames received by the FED; obtaining, by the NED and from the network connection, the first reflected test frame comprising the first unique sequence number, and a first FED receiving counter value from the FED, wherein the first FED receiving counter value is the value of the FED receiving counter after receiving the first test frame by the FED; obtaining, by the NED and from the network connection, the second reflected test frame comprising the second unique sequence number and a second FED receiving counter value from the FED, wherein the second FED receiving counter value is the value of the FED receiving counter after receiving the second test frame by the FED; extracting, by the NED, the first unique sequence number from the first reflected test frame and the second unique sequence number from the second reflected test frame; calculating, by the NED, a one-way frame loss value from the FED to the NED using the first unique sequence number, the second unique sequence number, the first FED receiving counter value, and the second FED receiving counter value; and determining, by the NED, whether one or more reflected test frames are dropped from the FED to the NED by using the first unique sequence number and the second unique sequence number.
