Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The inventor finds that the existing industry short message disaster recovery routing has the following problems:
first, only the disaster recovery routing of the link layer can be provided, and the disaster recovery routing of the service layer cannot be realized.
Fig. 1 is a schematic diagram illustrating an embodiment of a method for switching a route of an industry sms in the prior art. As shown in fig. 1, the industry short message configures a link-level disaster recovery route. The solid line part represents the primary route, and the dotted line part represents the backup route. The primary route has X, Y and other clients, and if only the route from the X client to the network node 1 has a fault, the standby route switching cannot be performed only for the X client.
For example, if a failure a occurs, the network node 1 can only perform a link-level route switching to simultaneously switch the industry short messages of the customer X and the customer Y to the standby route.
Secondly, only the link fault connected with the network node 1 can be detected, the fault of the industry short message downstream path or node cannot be detected, and a routing fault blind area exists.
Fig. 2 is a schematic diagram illustrating another embodiment of a method for switching a route of an industry sms in the prior art. As shown in fig. 2, the industry sms configures a link-level disaster recovery route. The solid line part represents the primary route, and the dotted line part represents the backup route.
For example, if a fault b occurs, at this time, only the industry short message route of the client Y has a fault, the industry short message route of the client is still normal, but the network node 1 does not sense the fault b, and does not know the link fault at the position b nor the industry short message route of the client Y has a fault. The network node 1 can perform neither the route switching of the link layer nor the route switching of the client Y service layer.
The route switching method according to an embodiment of the present invention is described below with reference to fig. 3.
Fig. 3 is a flowchart illustrating a route switching method according to an embodiment of the present invention. As shown in fig. 3, the route switching method of this embodiment includes:
step S302, route heartbeat servers are respectively arranged in the network node and the plurality of client systems.
The industry short message routing heartbeat server is mainly respectively arranged in a network node with a routing function and a client system. The industry short message routing heartbeat server is used for sending heartbeat short messages, receiving heartbeat short messages and responding heartbeat short messages.
Step S304, the routing heartbeat server at the network node communicates with the routing heartbeat servers at the plurality of client systems respectively through heartbeat messages, and determines the fault service route according to the heartbeat response messages of the heartbeat messages.
For example, a failed link in a failed traffic route may be determined based on whether heartbeat response messages are received from routing heartbeat servers located on multiple client systems.
Step S306, the standby service route is used to replace the failure service route.
For example, if a failed link exists in a route between a client system to a network node, the failed traffic route may be replaced with a backup route between the client system to the network node.
A specific application example of the route switching method is described below with reference to fig. 4 and 5. Fig. 4 shows a schematic diagram of a network node performing route switching when a failure a occurs. Fig. 5 shows a schematic diagram of a network node performing route switching when a failure b occurs.
Taking the uplink short message as an example, the routing heartbeat server in the network node 1 may simulate a terminal user to periodically send heartbeat short messages to all client systems, the client systems submit the heartbeat short messages to the routing heartbeat server in the client systems for processing after receiving the heartbeat short messages, and the routing heartbeat server in the client systems responds to acknowledgement information (for example, ACK, OK or an extended status code).
Whether a fault a or b occurs, the routing heartbeat server of the network node 1 cannot detect the response of the routing heartbeat short message of the client Y, and judges that the main route is abnormal, so that the routing switching of a service layer is performed on the industrial short message. As shown in fig. 4, if the routing heartbeat server of the network node 1 cannot detect the responses of the routing heartbeat messages of the client X and the client Y, it is determined that a failure a occurs, and the routing heartbeat server of the network node 1 performs route switching on both the client X and the client Y. As shown in fig. 5, if the routing heartbeat server of the network node 1 detects the response of the routing heartbeat short message of the client X but cannot detect the response of the routing heartbeat short message of the client Y, it determines that a failure b occurs, and performs routing switching only on the client Y.
In the embodiment, the routing heartbeat server is arranged in the industrial short message system, and the fault service route is determined through the heartbeat response message of the heartbeat message, so that the fault service route is replaced by the standby service route, the disaster recovery route switching of a service layer is realized, and the blind-spot-free fault link detection of the whole route is realized. Meanwhile, the technical scheme is realized in the existing network, hardware equipment is not required to be added, the existing network is slightly changed, only route heartbeat server software is required to be added, and therefore the implementation cost is low.
Preferably, in one embodiment, the heartbeat message may contain a specific character string, so that the network node preferentially processes the heartbeat message containing the specific character string.
For example, the content of the heartbeat short message may contain a specific character string. All network nodes through which the heartbeat short message passes can identify the content of the heartbeat short message, and the heartbeat short message containing the specific character string is processed with the highest priority, so that the heartbeat short message can be sent in priority.
By setting the specific character string in the heartbeat message, the heartbeat message can be transmitted preferentially, so that the existing fault can be detected as soon as possible in the network, and the delay of route switching is reduced.
Preferably, in one embodiment, heartbeat messages may be sent periodically or manually to determine the failed traffic route.
The heartbeat messages may be timed according to a preset event period, and the time period may be set to be timed to day, hour, minute, or second. Or manually to immediately detect whether the route is normal. And if the routing heartbeat server in the network node cannot receive the heartbeat response message within a period of time, performing routing switching of a service layer.
The above embodiments all take the route detection of the uplink as an example. It should be understood by those skilled in the art that, when detecting a failure in the network, a routing heartbeat server in the client system may also initiate downlink routing detection, send a heartbeat message to a routing heartbeat server in the network node, and determine whether a failure exists in the routing through a received heartbeat response message.
