Abstract: PURPOSE: A share mesh protection switching method and a device thereof are provided to prevent a chaotic situation in a share protection segment by delaying protection switching operation through an APS(Automatic Protection Switching) protocol. CONSTITUTION: An end node D reports a protection switching event to a share node Q after detecting errors of a working path W2(S301,S302). The end node D waits until a timer unit is terminated by operating the timer unit(S303). The share node Q confirms whether a share protection segment P-Q is available(S304). The end node D executes a protection switching process to a protection path P2 according to a linear protection switching protocol after the time set in the timer unit is terminated(S305).

Abstract: PURPOSE: A packet processing apparatus for an MPLS(Multi-Protocol Label Switching)-TP(Transport Profile) network and method thereof are provided to respectively execute service packet processing processes by managing a service by using data link layer information. CONSTITUTION: A packet processing apparatus acquire LSP(Label Switched Path) condition information(203). The packet processing apparatus acquires forwarding information and header information(204). When the SLSP(Service LSP) lable information of the forwarding information is matched with the SLSP information stored in a hash table, the packet processing apparatus determines the created service type or a temporary type(206,208). The required bandwidth of the determined service type is over the preestablished threshold values, the packet processing apparatus transmits the reception packet through an MPLS-TP(Multiprotocol Label Switching-Transport Profile) label encapsulation and the header update of the reception packet.

Abstract: An apparatus and a method for measuring the loss of frames in a multicast service environment are provided to measure the loss of frames accurately even without advance information about a change in a traffic route of the multicast service or a node from which traffic is outputted. An input frame-counting unit(200) counts data frames of a specific multicast service, which is included in a target net of which the loss of frames is to be measured. An output frame-counting unit(210) counts data frames of the specific multicast service, which is outputted from the target net. A loss-measuring unit(220) measures the frame loss by comparing the number of data frames counted by the input frame-counting unit with the number of data frames counted by the output frame-counting unit.
