Abstract: A MPLS-TP network includes a first router, at least one second router, and a third router. The first router is set to a MEP and generates and transmits a link trace packet. The second router is set to an MIP, generates a response packet in response to reception of the link trace packet, transmits the response packet in a direction of the first router, and forwards the link trace packet. The third router is set to the MEP, generates a response packet in response to reception of the forwarded link trace packet, and transmits the response packet in the first router direction.

Abstract: When a transmitting apparatus wants to transmit a preemptable frame, the transmitting apparatus transmits a preemptable packet by a custom preamble including frame length information on a payload of the preemptable frame to the payload of the preemptable frame. A receiving apparatus determines whether a received preemptable frame is fragmented using frame length information set in the custom preamble of the received preemptable frame. As described above, since it is possible to check whether the received frame is fragmented using the frame length information set in the custom preamble, there is no need to perform CRC calculation to determine whether the received frame is fragmented as in the prior art.

Abstract: A method in which a high-quality packet telephony terminal apparatus performing low-latency and lossless packet communication with a counterpart packet telephony terminal apparatus operates in an integrated network structure in which a time sensitive network (TSN) and a packet communication network are combined may be disclosed. The packet telephony terminal apparatus may perform packet telephony call processing, perform a TSN stream reservation procedure when the counterpart packet telephony terminal apparatus is capable of performing a TSN function for lossless packet communication, adjust a size of a dejitter buffer when the TSN stream reservation procedure is successful, and perform low-latency packet telephony communication through the minimized size of the dejitter buffer.
