Abstract: The present disclosure relates generally to a communication system, and more particularly, to a method for time-deterministic packet forwarding that guarantees a maximum and minimum latency requirement of a service, the method including: receiving latency information of links and nodes on a path, and buffer resource information of the nodes; calculating, on the basis of the buffer resource information of the last node, local latency budgets that the other nodes need to guarantee; performing control so that the nodes transmit a packet on the basis of the local latency budgets; and finally guaranteeing, by the last node, a residual latency budget remaining after the nodes transmit the packet within the local latency budgets.

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: 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.

Abstract: 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.

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.
