Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flowchart of a method for detecting a satellite link state according to an embodiment of the present invention, which is applicable to a case of detecting a satellite communication link failure, and is particularly applicable to a case of a failure between inter-satellite communication links. The method can be executed by a satellite link state detection device, and the device can be realized in a software/hardware mode. The method can be integrated in a satellite link state detection system server, and specifically comprises the following steps:
and S110, receiving a specified satellite link state detection request of a user.
In this embodiment, by implementing based on the B/S mode, specifically, an application program is deployed on the server side to be accessible to a plurality of PC clients. A user can send a specified satellite link state detection request at a PC client, and a server receives the corresponding specified satellite link state detection request.
Optionally, the method may further include the steps of: and verifying the user login information, and receiving a link state detection request of a specified satellite when the user login information passes the verification. Satellite communication link management requires a technician with a certain level of capability to perform. To ensure proper operation of the satellite communication system. User information needs to be confirmed to determine whether the user is an authorized user. When the verification is passed, the user can be confirmed as an authorized user, and the satellite link state monitoring request is received.
And S120, sending state query information to the satellite node of the specified satellite link.
The link failure in the satellite network may be a link outage due to a spatial environment or a link outage due to a satellite node port failure. After receiving the query request, the controller sends a message encapsulated with an LLDP message to all satellite nodes, the message is forwarded to all adjacent satellite nodes and then sent back to the controller, and the controller acquires the link state by analyzing the source node and destination node information carried in the message.
And S130, receiving the state parameters returned by the satellite nodes.
Illustratively, the controller receives the corresponding information to obtain the corresponding state parameter. Illustratively, the information may be an ofp _ port _ status message.
And S140, judging whether the information is abnormal or not according to the returned information, and providing a corresponding alternative scheme for the user to select when the information is abnormal.
For example, the determining whether the information is abnormal according to the returned information may include: and judging whether the state is abnormal or not according to the returned port link state. Optionally, the determining whether the port link status is abnormal according to the returned port link status may include: positioning the failed link and port and the satellite with the link failure according to the state of the port link; and comparing the signal received by the monitoring point corresponding to the link with a preset signal, and judging whether the link is abnormal or not according to the comparison result.
After receiving the status information, the failed link and port and the failed satellite can be located by a failure detection algorithm. Illustratively, the corresponding links, ports, and satellites may be determined by the network topology. Optionally, the ID and the corresponding relationship are set according to the original network topology, and the failed link and port and the failed satellite are located according to the corresponding relationship.
And comparing the signal corresponding to the corresponding link with the normal signal, and judging whether the signal is abnormal or not according to the comparison result. For example, whether or not there is an abnormality may be determined by comparing the ofp _ port _ status information with the normal ofp _ port _ status information.
Because the satellite network has the characteristic of extending propagation time, when an abnormality occurs, if recovery is performed, service flow interruption can have serious consequences during the recovery period. Thus, in this embodiment, corresponding alternatives may be provided, i.e. alternative lines for the user to select. The user may select an appropriate alternative line based on the performance for the fault recovery scheme. Two indexes of link failure recovery time and end-to-end delay can be selected for measurement.
The embodiment detects the request by receiving the appointed satellite link state of the user; sending state query information to the satellite node of the specified satellite link; receiving state parameters returned by the satellite nodes; and judging whether the information is abnormal or not according to the returned information, and providing a corresponding alternative scheme for the user to select when the information is abnormal. A better link detection scheme can be determined according to the requirements of users, fault points and fault reasons can be rapidly determined according to detection results, and satellite link detection can be completed in a short time.
In a preferred embodiment of this embodiment, the method may further include the following steps: and replacing the failed link according to the selected alternative scheme to recover the corresponding service. By the selected alternative scheme, the standby line can be quickly switched to, and smooth communication is guaranteed.
In another preferred embodiment of this embodiment, the method may further include the steps of: and recording the relevant information of the satellite link state detection operation and storing the information into a database so as to trace back the process. Through recording corresponding detection data and the detection process, the whole process is conveniently traced, so that the detection algorithm is adjusted according to the tracing process in the later stage, and various instructions are optimized.
