20090323705	METHOD FOR IMPLEMENTING PHOTOELECTRIC MUTEX, ETHERNET PHOTOELECTRIC MUTEX INTERFACE DEVICE AND NETWORK EQUIPMENT - A method for implementing photoelectric mutex, an Ethernet photoelectric mutex interface device, and network equipment are provided. The Ethernet photoelectric mutex interface device includes a channel switching module, a first Ethernet physical layer (PHY) chip, and a second Ethernet PHY chip. The channel switching module is connected to the first Ethernet PHY chip through a first interface and connected to the second Ethernet PHY chip through a second interface respectively, and is adapted to perform data transmission through the first Ethernet PHY chip and when a presence signal of an optical interface data transmission module is detected, perform data transmission through the second Ethernet PHY chip. Thus, a cost of equipment for implementing a photoelectric mutex function in an Ethernet is reduced, and a utilization rate of transmission resources is improved.	12-31-2009

20090262651	FAULT DETECTION METHOD, COMMUNICATION SYSTEM AND LABEL SWITCHING ROUTER - A fault detection method, a communication system, and an LSR are provided herein to overcome the inability of performing BFD packet resolution fault detection for multiple nodes in the conventional art. The method includes: determining a hop count between a first node and a second node on an LSP, where the second node is located downstream of the first node; encapsulating a BFD packet into an MPLS packet that carries information about the hop count between the first node and the second node; sending the MPLS packet from the first node along the active LSP; and judging, by the node that receives the MPLS packet, whether this node is the second node according to the hop count. If this node is the second node, extract the BFD packet for detect, and obtaining a fault detection result. Otherwise, forward the MPLS packet. Through the technical solution provided by the invention, the fault detection is more flexible in the MPLS.	10-22-2009
