Abstract: In the apparatus for controlling a transmission for lossless packet forwarding, when a failure is detected on one of a plurality of forwarding paths set between a transmitting node and a receiving node, packet transmission of a flow associated with the path in which the failure occurs is stopped, when the path in which the failure occurs is recovered, packet transmission of the flow is resumed, and the receiving node temporarily extends the bandwidth of the flow.

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: Disclosed are methods lossless traffic forwarding using distributed delay offset matching. The lossless traffic forwarding method includes calculating a delay offset between a first forwarding path between a transmitting node and a receiving node and a second forwarding path between the transmitting node and the receiving node, and controlling a buffer resource by an extent of the delay offset to delay packets to be forwarded on the first forwarding path.
