The invention relates to a linear protection switching method applicable to a large-capacity PTN (packet transport network) device. At a communication source end node, output ports are configured by a crossed unit into three service forwarding instances, namely a main NNI (network node interface) port, a standby NNI port, and a main-standby NNI port; keywords matched to generate target MAC (media access control) addresses, namely MACn1, MACn2, and MACn3; at a communication destination end node, the interface units of the main and standby NNI interfaces are respectively configured with service processing instances; and the keyword to be matched is a Tunnel label; however, only the main service instance is in activated state; during switching, corresponding switching operations are implemented according to protection modes (1-plus-1 protection and 1-to-1 protection). The most fundamental thought of the linear protection switching method applicable to the large-capacity PTN (packet transport network) device is to convert centralized switching into distributed switching; the crossed unit only implements high speed packet forwarding, and does not participate in switching motions; therefore, the switching motions are carried out by a plurality of service processing units; moreover, the service processing units process the switching motions concurrently, so the switching speed is improved by times.

The invention discloses an NNI (Network Node Interface) PING realization method and device.

The invention discloses a method for implementing service control in an all-fiber protection system and a device thereof. The method comprises the following steps: determining a primary port and a standby port of a network node interface (NNI), setting the spanning tree protocol status of the primary port to be a forwarding state, and setting the spanning tree protocol status of the standby port to be a learning state; and processing board-to-board communication messages between a main control board and an Ethernet passive optical network (EPON) subcard by the mode of a bridge protocol data unit (BPDU) via a switching chip. In the invention, service flow only passes through a main link; and in addition, when changeover occurs between the main link and a standby link, the service flow can be rapidly switched between the main link and the standby link, thus reducing packet loss and enhancing protective performance.
