Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a dual-server hot-standby routing management method according to the present invention, in this embodiment, the dual-server hot-standby routing management method includes the following steps:
step S10: judging whether an information synchronization request sent by a standby machine is received;
the server is one of computers, and provides calculation or application services for clients (such as terminals like PCs, smart phones, ATMs and the like, and even large-scale equipment like train systems and the like) in a network. If a server fails, there are various reasons causing the server failure, such as equipment failure, operating system failure, software system failure, etc., and it usually takes a lot of time to troubleshoot the failure reason and repair the failure according to the failure reason, resulting in long-time network interruption. For some important systems, if the network is interrupted for a long time, there are problems of information loss and data transmission being not timely. Therefore, long-time service interruption is avoided through the dual-computer hot standby, and long-term and reliable service provision of the system is guaranteed. The dual-server hot standby refers to a solution, and for important services, two servers are used for mutual backup and executing the same service together. When one server fails, the other server can undertake the service task, so that the system can be automatically ensured to continuously provide the service without manual intervention. In addition, routing management can be performed between two servers through OSPF (Open Shortest Path First), which is a link state-based interior gateway protocol developed by IETF (Internet Engineering task force) organization; two routers can dynamically learn link or routing information of each other through OSPF networking, and for a more complex networking environment, OSPF is generally used for routing management. One of the two servers is used as a host machine, and the other server is used as a standby machine. When the host and the standby are started, the OSPF services of the host and the standby respectively enter into own working modes, and connection is established through socket. After the connection is completed, because the information is empty when the standby machine is initialized, the host machine needs to actively send an information synchronization request to the host machine for full synchronization, so that when the host machine and the standby machine are started, the host machine firstly judges whether the information synchronization request sent by the standby machine is received, and whether the host machine receives the information synchronization request sent by the standby machine depends on whether the standby machine sends the synchronization information request.
Step S20: synchronizing target information to be synchronized to a standby machine, and determining a target algorithm for performing routing calculation on the target information so that the standby machine performs routing calculation on the target information according to the target algorithm to obtain target routing information;
after the step of determining whether an information synchronization request sent by the standby machine is received, if the information synchronization request sent by the standby machine is received, determining corresponding target information to be synchronized according to the information synchronization request, and synchronizing the target information to the standby machine, where the target information to be synchronized may include: interface information, neighbor information, link state broadcast information update information, neighbor information update information, interface information exception information, and the like. After target information to be synchronized is synchronized to a standby machine, a target algorithm for performing route calculation on the target information by a host machine is determined, wherein the target algorithm can be a Dijkstra algorithm and other route calculation algorithms, and can be determined according to specific use conditions or application scenes. Determining that the target algorithm can enable the host to perform routing calculation on corresponding target information through the target algorithm to obtain host routing information, so as to perform corresponding routing management according to the host routing information when the host works normally; in addition, the determined target algorithm can be used as a route calculation algorithm of the standby machine, so that when the information of the standby machine is consistent with the information of the host machine, the same route information can be obtained if the standby machine adopts the same algorithm as the host machine to perform route calculation on the same information, and the route information of the host machine and the route information of the standby machine are ensured to be consistent. After the target information to be synchronized is synchronized to the standby machine, the standby machine enters a route calculation process according to the received target information, and autonomously calculates corresponding route information, at the moment, after a target algorithm for performing route calculation on the target information is determined, the target algorithm is used as a route calculation algorithm of the standby machine, so that the standby machine performs route calculation on the target information through the target algorithm. Because the standby computer has the same calculation source (target information) and the same routing algorithm (target algorithm), after the standby computer performs routing calculation on the target information through the target algorithm, the standby computer obtains the target routing information obtained by performing the routing calculation on the target information through the target algorithm, so that the routing information obtained by the calculation of the standby computer can be consistent with the routing information obtained by the calculation of the host computer.
When the information synchronization request sent by the standby machine is not received, the information cannot be synchronized to the standby machine, and the routing information of the standby machine is inconsistent with the routing information of the host machine. In order to ensure the consistency of the routing information of the host and the standby machine, if the information synchronization request sent by the standby machine is still not received within the preset time, the standby machine can send the information synchronization request to the host again, at the moment, whether the information synchronization request sent by the standby machine is received is judged again, and the requested information is synchronized to the standby machine until the information synchronization request sent by the standby machine is received. If the time for not receiving the information synchronization request sent by the standby machine exceeds the preset time threshold, the problems such as communication connection and the like may exist between the host and the standby machine, after the problems are eliminated, the standby machine can continuously send the information synchronization request to the host, and whether the information synchronization request sent by the standby machine is received or not is judged again until the information synchronization request sent by the standby machine is received. It is worth noting that whether the host receives the information synchronization request sent by the standby machine or not, a target algorithm for performing route calculation on the target information needs to be determined, and on one hand, the host can calculate the route information of the target information through the determined target algorithm; on the other hand, the standby machine adopts the same target algorithm as the host machine to calculate the routing information of the target information, even if the information of the host machine and the standby machine is not synchronous, the routing information of the host machine and the standby machine can be ensured to be the same as much as possible, and therefore when the host machine fails and is switched to the standby machine to execute the routing management operation, the network interruption time is reduced.
Step S30: when entering a fault state, switching to a standby machine, and executing routing management operation by the standby machine according to the target routing information;
and before switching to the standby machine and executing the routing management operation by the standby machine according to the target routing information, judging whether fault information exists or not. In a preferred embodiment, whether the host has the fault information is determined according to whether the heartbeat information received by the standby machine within a first preset time includes the host fault information or whether the standby machine receives the heartbeat information within a second preset time. If the heartbeat information received by the standby machine in the first preset time contains the host fault information or the heartbeat information is not received by the standby machine in the second preset time, judging that the fault information exists; and when the heartbeat information received by the standby machine in the first preset time does not contain the host fault information or the heartbeat information is received in the second preset time and the heartbeat information part contains the host fault information, judging that no fault information exists. The first preset time is the preset interval time for the host to send heartbeat information to the standby machine, the second preset time is the preset time for judging whether the host fails, and the second preset time is greater than the first preset time.
When the host computer is judged to have fault information, the dual-computer switching is directly carried out, and the standby computer executes the routing management operation according to the calculated target routing information. When the host enters a fault state, because the routing information of the standby machine is consistent with the routing information of the host, when the host is switched to the standby machine to execute the routing management operation, the network interruption is not needed or the time for interrupting the network is extremely short, even the time is as short as the time which is difficult to capture by the prior art, and the seamless butt joint of the host and the standby machine can be basically realized.
In this embodiment, by determining whether an information synchronization request sent by a standby machine is received, if the information synchronization request sent by the standby machine is received, target information to be synchronized is synchronized to the standby machine, and a target algorithm for performing routing calculation on the target information is determined, so that the standby machine performs routing calculation on the target information according to the target algorithm to obtain target routing information, so as to ensure consistency between the routing information of the standby machine and the routing information of a host machine, so that when the standby machine enters a fault state, the standby machine is switched to the standby machine, and the standby machine performs routing management operation according to the target routing information, so that a network does not need to be interrupted to re-exchange routing information with a corresponding router, or the interruption time is extremely short, thereby avoiding information loss caused by network interruption, and improving the efficiency of routing management.
Referring to fig. 3, fig. 3 is a flowchart of a second embodiment of the dual-computer hot-standby routing management method of the present invention, in this embodiment, the dual-computer hot-standby routing management method includes the following steps:
step S11: judging whether an information synchronization request sent by a standby machine is received;
step S12: if so, acquiring interface information, neighbor information and link state broadcast information;
step S13: taking the interface information, the neighbor information and the link state broadcast information as target information to be synchronized;
step S14: synchronizing the target information to be synchronized to a standby machine, and determining a target algorithm for performing routing calculation on the target information so that the standby machine performs routing calculation on the target information according to the target algorithm to obtain target routing information;
step S15: and when the router enters a fault state, switching to the standby machine, and executing the routing management operation by the standby machine according to the target routing information.
In this embodiment, whether an information synchronization request sent by the standby machine is received is determined, and if the information synchronization request sent by the standby machine is received, after receiving the link state broadcast information and the neighbor information sent by the neighbor router, the received neighbor information, the link state broadcast information, and the corresponding interface information are acquired, at this time, the interface information, the neighbor information, and the link state broadcast information of the host are used as target information to be synchronized, and the target information to be synchronized is synchronized to the standby machine. And determining a target algorithm for performing routing calculation on the target information, so that the standby machine performs routing calculation on the target information according to the target algorithm to obtain target routing information, so as to ensure the consistency of the routing information of the host machine and the standby machine, so that when the host machine enters a fault state, the host machine is directly switched to the standby machine, and the standby machine performs routing management operation according to the routing information to manage all routing information in the networking.
In a specific operation process, the target information of the host may be dynamically changed due to the influence of other external routers. When the target information of the host changes, the host actively sends a notification message to the standby machine, and synchronously changes the target information of the standby machine according to the changed target information to realize incremental synchronization. Therefore, in an embodiment, after the step of synchronizing the target information to be synchronized to the standby machine, the method further includes: judging whether the link state update information exists or not; and if so, sending the updating information to the standby machine so that the standby machine can update the link state broadcast information according to the updating information. If the host receives the update information of the link state broadcast information of other neighbor routers, the host is judged to have the update information of the link state, and the update information is sent to the standby machine so that the standby machine can update the link state broadcast information of the standby machine according to the update information, and therefore the link state broadcast information of the standby machine is ensured to be consistent with the link state broadcast information of the host. The update information of the link state broadcast information may include: link state update information such as addition and deletion of links, adjustment of links, and the like.
In an embodiment, after the step of synchronizing the target information to be synchronized to the standby machine, the method further includes: judging whether update information of a neighbor router exists or not; and if so, sending the updating information to the standby machine so that the standby machine updates the neighbor information of the standby machine according to the updating information to keep consistent with the neighbor information of the host machine. Judging whether the host has the update information of the neighbor router according to whether the neighbor router connected with the host has the change, if so, judging that the update information of the neighbor router exists, and sending the update information to the standby machine so that the standby machine can update the neighbor information of the standby machine according to the update information to ensure that the neighbor information of the standby machine is consistent with the neighbor information of the host. The update information may include: and adding, deleting or replacing information of the neighbor router connected with the host, and the like.
In an embodiment, after the step of synchronizing the target information to be synchronized to the standby machine by the control host, the method further includes: judging whether the update information of the interface exists or not; and if so, sending the updating information to the standby machine so that the standby machine updates the interface information of the standby machine according to the updating information, so that the interface information of the standby machine and the interface information of the host machine are kept consistent. Under certain specific conditions, if part of working ports of the host cannot work normally, the data information cannot be continuously acquired from the corresponding working ports, therefore, after the step of synchronizing the target information to be synchronized to the standby machine by the control host, whether the host has the update of the interface is judged, if the host has the update of the interface, the host is judged to have the update information of the interface, and at the moment, the control host sends the update information to the standby machine so that the standby machine updates the interface information of the standby machine according to the update information, and the consistency of the interface information of the standby machine and the interface information of the host is ensured. In addition, the interface updating information can also comprise abnormal information of the interface besides the addition and deletion information of the interface, if part or all of the interfaces of the host computer are abnormal, a corresponding interface switching command is generated and sent to the standby computer, so that the standby computer switches the corresponding interface of the standby computer to a working state to transmit data according to the interface switching command, and the host computer is switched back to after the abnormal interface of the host computer is repaired, and the interface of the host computer is utilized to perform corresponding data transmission operation.
It should be noted that if there are two or more updates in the interface information, the neighbor information, and the link state broadcast information, two or more updates are sent to the standby machine at the same time, that is, as long as there are any updates (which may be one, two, or three updates), the interface information, the neighbor information, and the link state broadcast information of the standby machine will be sent to the standby machine, so that the interface information, the neighbor information, and the link state broadcast information of the standby machine can be completely consistent with the host machine. Therefore, after the consistency of the interface information, the neighbor information and the link state broadcast information of the standby machine and the interface information, the neighbor information and the link state broadcast information of the host machine is ensured, the consistency of the routing information of the standby machine and the routing information of the host machine can be ensured according to the routing algorithm, so that when the host machine enters a fault state, the standby machine is directly switched to, and the standby machine executes routing management operation according to the calculated target routing information.
In this embodiment, when an information synchronization request of a standby device is received, interface information, neighbor information, and link state broadcast information are synchronized to the standby device as target information to be synchronized, and a target algorithm for performing routing calculation on the target information is determined, so that after the standby device performs routing calculation on the target information according to the target algorithm to obtain target routing information, if a host enters a fault state, the standby device is switched to the standby device, and the standby device performs routing management operation according to the routing information.

step S21: judging whether an information synchronization request sent by a standby machine is received;
step S22: if the target information is received, the control host synchronizes the target information to be synchronized to the standby machine, and determines a target algorithm for performing routing calculation on the target information, so that the standby machine calculates the target information according to the target algorithm to obtain target routing information;
step S23: when entering a fault state, switching the current mode into a client mode, and sending a mode switching command to the standby machine so as to switch the mode of the standby machine into a server mode;
step S24: and switching to the standby machine according to the switched mode, and executing the routing management operation by the standby machine according to the target routing information.
After the servers are connected, it is impossible to determine which server is the master and which is the slave, and therefore it is impossible to determine from which server the information synchronization request is sent. Therefore, when the two servers are both started, different priorities are configured for the two servers, the server with the high priority is determined as the host, the server with the low priority is determined as the standby, and then the information synchronization request is generated and sent to the host by setting the standby. In order to avoid information loss caused by network faults and other reasons, a host judges whether an information synchronization request sent by a standby machine is received or not, synchronizes target information to be synchronized to the standby machine when the information synchronization request sent by the standby machine is received, and determines a target algorithm for performing routing calculation on the target information so that the standby machine performs routing calculation on the target information according to the target algorithm to obtain target routing information.
When the host enters a fault state, because the dual hot-standby devices can be mutually backed up, the dual switching can be realized in a priority switching mode: if the host computer is in failure, the priority of the standby computer is switched to be higher than that of the host computer, at the moment, if the standby computer receives an information synchronization request sent by the host computer, the host computer can work normally, after the standby computer synchronizes target information to be synchronized to the host computer, the standby computer can be continuously controlled to execute the routing management operation until the standby computer enters a failure state, the priority of the host computer is switched to be higher than that of the standby computer again, the host computer with high priority executes the routing management operation, or after the standby computer synchronizes the target information to be synchronized to the host computer, the priority of the host computer is directly switched to be higher than that of the standby computer, and the host computer with high priority executes the routing management operation. Namely, the corresponding priority switching is carried out as long as the dual-computer switching occurs, and the priority can be automatically switched according to the pre-configured priority switching command when the dual-computer switching occurs. Certainly, when the host enters a fault state, that is, the host cannot normally operate with a high priority, at this time, switching of the priority may not be performed, the standby with a low priority is defaulted to perform the routing management operation according to the routing information until the standby receives an information synchronization request sent by the host, which indicates that the host can normally operate, at this time, the standby is controlled to synchronize target information to be synchronized to the host, after the host receives the synchronized target information, the host is preferentially selected according to the priority order to perform the routing management operation, and the standby is restored to a standby state, until the host enters the fault state again, the standby is controlled to perform the routing management operation.
In an embodiment, when the host enters a failure state, the dual-computer switching is realized by a mode switching manner. Before entering a fault state, the mode of the host is a server mode, the mode of the standby machine is a client mode, and at the moment, the host in the server mode executes routing management operation; and after the host enters a fault state, the host needs to be switched to the standby machine, and the standby machine executes the routing management operation, at this time, the current mode of the host is switched from the server mode to the client mode, and a mode switching command is sent to the standby machine so as to switch the mode of the standby machine to the server mode, so that the host is switched to the standby machine, and the standby machine in the server mode executes the routing management operation. After the standby machine in the server mode executes the routing management operation, if the fault of the host machine is repaired, the host machine can normally work, the current working mode can be continuously maintained at the moment, and the standby machine executes the management operation, so that the problem that the processing efficiency of the system is influenced due to information loss caused by frequent switching between the host machine and the standby machine is avoided; or sending an information synchronization request to the standby machine to receive the synchronization information sent by the standby machine, switching the current mode from the client mode to the server mode after receiving the synchronization information, and sending a mode switching instruction to the standby machine to switch the mode of the standby machine from the server mode to the client mode, so that the standby machine is switched back to the host machine according to the switched mode to execute the routing management operation by the host machine in the server state. The mode switching command can be sent manually or automatically by a system, and the automatic sending condition can be that one of the two hot standby parties enters a fault state, or that one of the two hot standby parties sends an information synchronization request after entering the fault state.
In this embodiment, by determining whether an information synchronization request sent by a standby machine is received, when the information synchronization request of the standby machine is received, target information to be synchronized is synchronized to the standby machine, and a target algorithm for performing routing calculation on the target information is determined, so that the standby machine performs routing calculation on the target information according to the target algorithm to obtain target routing information.
