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 apparatus and method for protection switching are disclosed. The protection switching method in accordance with an example of the present disclosure is capable of smoothly processing a protection switching while preventing a data path mismatch occurring in the protection switching in a case in which a forced switching command (FS), which is a passive command, and a signal failure (SF) of a protection path occur at both end nodes, respectively, when a linear protection switching is performed by use of a protection state coordination message in a packet network or a packet transport network.

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: In a network in which a plurality of protection paths have been formed for one working path between a first node and a second node, each node determines preference levels corresponding to an order to be preferentially used when performing protection switching on the plurality of protection paths. Next, each node exchanges pieces of information about the preference levels determined for the plurality of protection paths.

Abstract: Provided is a failure recovery method in a non-revertive mode of an Ethernet ring network. In an Ethernet ring network, link priorities between nodes or node priorities are determined based on media access control (MAC) addresses and the nodes having blocked ports are determined after failures are recovered from based on the priorities so that the blocked ports can be distributed.
