The invention provides a fault location method and a server, relates to the technical field of computers, and used for quickly and accurately locating faults when CATERR (Catastrophic Error) or IERR (Internal Error) type faults occur. The fault location method comprises the following steps: detecting a fault notification message; indicating that deadly hanging type faults have occurred by the fault notification message; acquiring wrong data, and determining timeout errors corresponding to the deadly hanging type faults in the wrong data; reading wrong addresses in address registers of the timeout errors; matching the wrong addresses with an address space pre-stored in a PCIe (Peripheral Component Interface Express) equipment address space table; and if the address space matched with the wrong address exists in the PCIe equipment address space table, then determining PCIe equipment corresponding to the address space is a fault source which causes the deadly hanging type faults.

Embodiments of the present invention provide a method and a device for processing location information of a fault point. The method includes: obtaining, by an ingress node of a tunnel, first location information of a fault point on a link traversed by the tunnel, where the first location information of the fault point includes an identifier of an upstream node of the fault point and an identifier of an interface that is connected to the fault point and located on the upstream node of the fault point; and providing, by the ingress node, the first location information of the fault point to a user so that the user determines a location of the fault point corresponding to a tunnel fault. With the technical solutions of the present invention, the location of the fault point can be determined, and efficiency of troubleshooting specific to the tunnel fault can be improved.

An embodiment of the invention provides a method of channel fault notification and network equipment. The method comprises the following steps that the network equipment detects whether a first channel, on which the network equipment is positioned, generates a fault; when it is detected that the first channel generates the fault, fault information is obtained; first fault notification information is transmitted to the other network equipment on the first channel, and the first fault notification information carries the fault information; and the fault information can be directly obtained by the other network equipment on the first channel in real time, so that the accuracy rate and the timeliness for obtaining the fault information of the first channel are improved.

The embodiment of the invention provides a request message processing method and device. The method comprises the following steps: a gateway receives a request message sent by a client; the gateway determines a first application programing interface API corresponding to the request message; the gateway determines a running state of the first API according to the currently executed publishing stepin a preset publishing scheme, wherein the running state comprises a publishing state, and a unpublished state, and the publishing scheme comprises multiple publishing steps and identifiers of the corresponding API in the publishing state; the gateway determines a target service instance according to the running state of the first API, wherein the version of the API loaded by the target service instance is corresponding to the running state of the first API; the gateway sends the request message to the target service instance, thereby enabling the target service instance to process the requestmessage according to the loaded first API. The method provided by the embodiment of the invention is used for improving the service publishing efficiency.

The invention discloses a protection switching method and a protection switching device. The method comprises following steps of obtaining first control information and protection group type control information corresponding to a switching point between a master path and a backup path before a protected business is forwarded; on the premise that the obtained protection group type control information corresponding to the switching point matches with the protection group type actually corresponding to the switching point, controlling the protected business to be sent at the switching point by the master path or the backup path according to the obtained first control information corresponding to the switching point; in this way, when the master path or the backup path generates a fault and the path needs to be switched, the switching operation can be finished only by modifying the first control information; the work in the protection switching operation can be simplified; the simpleness and high efficiency of the protection switching operation can be ensured; and moreover, the multi-level switching protection can be realized.

Protection switching method and protection switching device

The embodiment of the invention provides a positional information processing method and positional information processing equipment of a fault point. The method comprises the following steps of: acquiring first positional information of the fault point of a tunnel passing through a link by an entering node of the tunnel, wherein the first positional information of the fault point comprises a mark of an upstream node of the fault point and a mark which is connected with an interface of the fault point and is on the upstream node; and providing the first positional information of the fault point for a user by the entering node so that the user can determine the position of the fault point corresponding to tunnel fault. By the technical scheme provided by the invention, the position of the fault point can be determined, and fault troubleshooting efficiency in allusion to tunnel fault is further improved.
