Abstract: Disclosed is a method of handing a fault in a software defined networking (SDN) network. First, information about an indirect port switched when a fault occurs in a flow table is set. When a fault is sensed, after information about an indirect port corresponding to the port in which the fault has occurred is obtained, the port in which the fault has occurred is switched into the obtained indirect port based on the obtained indirect port information. Thus, when a fault occurs, the fault can be rapidly handled so that the continuity of traffic transmission can be guaranteed.

Abstract: A hand-over packet loss control method in an Internet service system is provided to maintain the connection state through a transfer Internet protocol version 6 when changing the data transmission path. At the first point of time(T1), a process for searching continuously the movement toward a new access router(122) is performed. Because the present moving node(110) is not moved to the new access router, an HA(Home Agent)(140) and an opponent node(150) have the address of PCoA and transmit the data packet including a class and a label to an MAP(Mobility Anchor Point)(130). The MAP maintains the information included in the received packet and transmits the received packet to a previous access router(121) corresponding to the class and label on a binding update table. The previous access router transmits the received packet to the moving node. The moving node produces the data packet as a source of PCoA and transmits the produced data packet to the MAP through the previous access router. The transmitted packet includes the address of the opponent node.

Abstract: A maintenance signal delivery method among multiple layers in an EoS(Ethernet over SONET/SDH) transmission device is provided to define relations among maintenance signals which are independently generated from an Ethernet layer and SONET/SDH(Synchronous Optical Network/Synchronous Digital Hierarchy) layers, so as to deliver the maintenance signals quickly among the layers to ensure signal continuity. Mutual conversion relations among maintenance signals of SONET/SDH layers(31), a maintenance signal of an EoS adaptive layer(32), and a maintenance signal of an Ethernet layer(33) are previously defined. The maintenance signals which are independently generated at the layers(31-33) are mutually converted by using the defined conversion relations, and the converted signals are mutually delivered to the respective layers.

Abstract: A method and a device for detecting a fault by protection switching in SONET(Synchronous Optical NETwork)/SDH(Synchronous Digital Hierarchy) equipment are provided to enhance reliability for fault detection in an operator system or other devices by transmitting the fault detected in the SONET/SDH equipment to the operator system or other devices. Each fault detector(110) detects the fault from a signal input terminal(150) of an SONET/SDH interface(170) in real-time. Each fault controller(120) transfers the detected fault information to the operator system or other devices(130) if the detected fault information is over a predetermined threshold. A protection switching part(140) performs a protection switching service by using the fault detected in the fault detector if the detected fault information is not over the predetermined threshold. The protection switching part is at least one of 1+1, 1:1, 1+N, and UPSR(Unidirectional Path Switched Rings).
