Abstract: A method and an apparatus for managing QoS(Quality of Service) profiles are provided to effectively execute QoS management by providing optimized QoS according to multimedia services. An apparatus for managing QoS profiles comprises a QoS profile management part(120), a QoS profile application management part(130), a user interface part(110) and a device interface part(150). The QoS profile management part(120) stores and manages a QoS profile according to a QoS profile management command. The QoS profile application management part(130) outputs a QoS profile application or release command to one of many transfer devices according to the QoS profile management command, and manages a QoS profile list applied to the selected transfer device. The user interface part(110) receives the QoS profile management command, and forwards it to the QoS profile management part(120) or the QoS profile application management part(130). The device interface part(150) forwards the QoS profile application or release command to the selected transfer device.

Abstract: PURPOSE: A network connection releasing method using an RSVP(Resource Reservation Protocol) in all-optical network is provided to increase a stability of a network and effectively protect a network resource by preventing generation of a protection and restoration process. CONSTITUTION: A source node(10) inserts an error code(120) of Deletion in Process into a reservation error(ResvErr) message(110) and transmits it to an ingress node(20) of an all-optical network(S101). The ingress node(20) disables an alarm monitor(S102) and transmits an ACK message to the source node(10)(S103). An egress node(30) also receives an ResvErr message(110) and transmits the ResvErr message with the error code of Deletion In Progress inserted therein to a destination node(40). The destination node(40) turns off an alarm function on the LOL(Loss of Light)(S106) and transmits an ACK message to the egress node(30) of the all-optical network(S107). In addition, the destination node(40) releases every state related to connection and connections, sets a Path_State_Removing flag(150) of a path error(PathErr) message(140), and transmits it to the egress node(30) of the all-optical network(S108). The egress node(30) transmits an ACK message to the destination node(40)(S109), and transmits the PathErr message to a downstream(S110). The ingress node(20) transmits the PathErr message(140) to the source node(10)(S111). The source node releases every state and connection of itself, and transmits an ACK message(S112).

Abstract: PURPOSE: A bandwidth adaptive transcoding method using a frame drop rate is provided to compare a frame transmission number calculated based on a regular time interval with a reference frame number, to obtain the frame drop rate, and to decide a size of a video frame appropriately for a traffic condition of an accessing Internet user for transmission. CONSTITUTION: A VOD(Video On Demand) server transmits video stream on the request of an Internet user(201). A transcoding server analyzes an MPEG(Moving Picture Experts Group) 1/2 header(202) and a frame header, and increases a counter(fc) of a frame number and a value(tc) of a self-timer(203,204). Whether the value of the self-timer reaches a reference time(T) is checked(205). If not, video transmission is performed and the steps of 203 to 205 are repeated. If the value of the self-timer reaches the reference time, a transmission frame number(f) per second is calculated(207). A frame counter is initialized(208), and a difference between a reference frame number(F) and the frame transmission number is checked(209). If the frame transmission number is smaller than the reference frame number, transcoding is not performed and the 203 step is returned while continuously transmitting frames. If the frame transmission number is larger than the reference frame number, a frame drop rate(D) is calculated by subtracting the frame transmission number from the reference frame number(210). Transcoding based on frame dropping is performed on the basis of the calculated frame drop rate(211).
