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.
