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.

Abstract: Provided is a data processing system, including: a plurality of line matching blocks each including a data processor configured to store predefined preliminary transmission tables corresponding to the respective events requiring change of a data path, to determine whether to change a transmission table based on information received through an internal communication device, and to select and activate a preliminary transmission table corresponding to an event from among the preliminary transmission tables, wherein the preliminary transmission tables include destination information on all the physical or logical paths; and a shared bus configured to enable information on an event requiring change of the data path to be transmitted and received between the plurality of line matching blocks.

Abstract: In order to perform protection switching of a frame that is transmitted and received between a packet processor and a host processor, when an input frame is a receiving frame and a signal failure has occurred, by transporting a message including a protection switching command to a packet processor, protection switching is performed. Information representing that protection switching is performed is recorded in a header of the receiving frame, and a frame including a message including a corresponding header is transported to the host processor.

Abstract: A frame transmission controlling apparatus includes: a list configuration unit managing a parameter related to a gate control; a cycle timer unit managing a start timing of a cycle; a list executing unit performing the gate control based on the parameter, wherein the list executing unit includes: a cycle executing state machine setting an expiration time of at least one section included in the cycle, checking gate operation information corresponding to a list pointer indicating the at least one section, and performing a control corresponding to the gate operation information; a delaying state machine deducting and updating the expiration time by a predetermined unit; a cycle holding state machine generating a control signal indicating stopping transmission in MAC; and a cycle releasing state machine generating a control signal indicating resuming the transmission in MAC.
