A method of determining packet loss ratio between two communications nodes, the method comprising: transmitting at least one loopback packet configured to be propagated from a first node through a second and third nodes back to the first node; upon traversal of the second node inserting into the loopback packet a first counter for a number of packets sent from the second node to the third node prior to receiving the loopback packet; upon traversal of the third node inserting into the loopback packet a second counter for a number of packets received by the third node from the second node prior to receiving the loopback packet; upon return of the loopback packet to the first node, determining a packet loss ratio between the second and third nodes responsive to the first counter number and the second counter number inserted into the loopback packet.

Triangle loopback

A method of characterizing a communications channel between two communications nodes, the method comprising: determining at least one feature of a communications path between a first communications node and a second communications node; determining at least one feature of a communications path between the first communications node and a third communications node; transmitting at least one packet from the first node to propagate through the second and third nodes and return to the first node; and determining at least one feature of the communications channel between the second and third nodes responsive to receiving the packet at the first node, the at least one determined feature of the first node and the second node, and/or information comprised in the packet.
