What's the definition of throughput? As defined in [RFC1242], “the throughput is the maximum rate at which none of the offered frames are dropped by the device”. In MPLS-TP context the concept of throughput is not just for a particular device, but extended to apply to an MPLS- TP connection which could be a PW, LSP or Section.

What's the definition of One-way and Two-way throughput estimation? One-way throughput indicates only the throughput for the forward direction of the MPLS-TP connection. Also note that only the initiator MEP needs to send test traffic for one- way throughput estimation. Two-way throughput indicates both the throughput for the forward direction of the MPLS-TP connection and the throughput for the reverse direction of the connection. Also note that both the initiator MEP and the peer MEP need to send test traffic for two-way throughput estimation.

What's the format of Indication Packet for throughput estimation? The Indication Packet flows over G-ACh of an MPLS-TP connection

What's the format of Indication Message for two-way throughput estimation? Figure 1 Figure 2 Figure 3

What's the format of Test Packet for throughput estimation? Like Indication Packet, the Test Packet also flows over G-ACh
