A method and apparatus for processing DetNet traffic through the steps of receiving configuration information for configuring a DetNet node from a DetNet controller of a DetNet system and configuring a UPF, a DS-TT, and/or a NW-TT in a mobile communication system as the DetNet node are provided.

Method and apparatus for processing DetNet traffic

Provided is an apparatus and method for a centralized ultra-precision network control framework controlling heterogeneous multiple network domains to provide a large-scale end-to-end ultra-precision service in a communication system. A method of operating a network domain controller in a communication system includes: receiving node information, link information, adjacent node information, and adjacent node link information from a network node control agent; identifying controller topology information based on the node information, the link information, the adjacent node information, and the adjacent node link information; and transmitting boundary node information, boundary node link information, adjacent domain node information, and adjacent domain node link information to a network orchestrator.

Apparatus and method for centralized ultra-precision network control framework controlling heterogeneous multiple network domains in communication system

An autonomous quality of service provisioning apparatus and method are disclosed. The apparatus includes a parameter extraction unit receiving a packet transmitted from a transmitting terminal and extracting QoS parameters by analyzing the received packet; and a quality of service reservation unit configured to be associated with a controller that manages and controls resources of the network to request the controller to reserve resources corresponding to the extracted QoS parameters.

Autonomous quality of service provisioning apparatus and method

Method and apparatus for processing DETNET traffic

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.

Packet telephony terminal apparatus and operating method thereof

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.

Method and apparatus for controlling transmission for lossless packet forwarding

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.
