Abstract: Disclosed is a method and apparatus for transmitting an object which includes packets and is significant for an application of a receiver, the method including calculating a network latency between a sender and a receiver through a control message for transmitting a plurality of packets constituting the object, detecting that a specific packet is lost among the plurality of packets, calculating a retransmission required time required for retransmitting the specific packet, comparing the retransmission required time with a deadline, and transmitting a NACK message including information related to retransmission of the specific packet to the sender when the retransmission required time is within the deadline, wherein the network latency is used for calculating the deadline determined by latency times for transmission of the object.

Abstract: Disclosed are a network latency measurement method and apparatus for a low latency immersive service. The network latency measurement method includes transmitting a request message for measuring network latency from a first end node to a second end node, calculating a node latency at each node present between the first end node and the second end node and inserting the calculated node latency into the request message, and measuring a one-way network latency from the first end node to the second end node based on the node latency at each of the nodes inserted into the request message at the second end node.

Abstract: There are provided a method, a system, and a computer-readable recording medium for processing network traffic. A method for processing network traffic using a switching application specific integrated circuit (ASIC) includes generating, by a software forwarder operated in a software-based network operating system, a message including network processing information, transmitting the message to a switch manager operated in a hardware-based network operating system, learning, by the switch manager, the network processing information, and controlling the switching ASIC with reference to the learned information.
