    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: An apparatus and method for guaranteeing deterministic latency in a communication system is proposed. The method of operating enqueue packet processing may include extracting cycle information of a received packet from the received packet, identifying at least one of enq_myQ, enq_mateQ, and enq_mateQ_hold states of a queuing state parameter of an enqueue process for a previous packet for each flow at a reception node, identifying whether a cycle parameter for performing a CQF operation for the previous packet for each flow in the reception node is the same as a cycle parameter for performing the current CQF operation, identifying whether a cycle parameter included in the previously received packet for each flow in the reception node is the same as a cycle parameter included in a currently received packet, and storing (enqueuing) the received packet on the basis of the identifying processes and storing information about the received packet.
