Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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.
As will be appreciated by one skilled in the art, aspects of the present application may be embodied as a system, method or program product. Accordingly, various aspects of the present application may be embodied in the form of: an entirely hardware embodiment, an entirely software embodiment (including firmware, microcode, etc.) or an embodiment combining hardware and software aspects that may all generally be referred to herein as a "circuit," module "or" system.
As described in the background art, in the related art, when the traffic forwarding process exits abnormally or is stuck, the monitoring program in kyoto is responsible for restarting the traffic forwarding process, and there is a network failure fault, which cannot meet the requirement of the user for high reliability of the network. Based on the application, a message forwarding method is provided to solve the technical problem.
The message is a data unit exchanged and transmitted in the network, i.e. a data block to be sent by the station at one time.
The following describes a message forwarding method, an apparatus, a computing device, and a storage medium provided by the present invention in more detail with reference to the accompanying drawings and embodiments.
The method comprises the following main ideas that a shared message memory area is established by a standby process (hereinafter referred to as a bypass process), a flow forwarding process forwards messages in the shared message memory area, the bypass process monitors the flow forwarding process, and after the abnormality of the flow forwarding process is monitored, a CPU used when the flow forwarding process forwards the messages is used for forwarding the messages in the shared message memory area.
Fig. 2 is a schematic diagram of a packet forwarding method according to an embodiment of the present invention. In fig. 2, both the traffic forwarding process and the bypass process may forward the message in the shared message memory area, the solid line represents that the traffic forwarding process forwards the message in the shared message memory area, and the dotted line represents that the bypass process forwards the message in the shared message memory area.
The following describes the message forwarding method in detail.
As shown in fig. 3, a method for forwarding a packet according to an embodiment of the present invention includes:
s301, the message in the shared message memory area is forwarded through the flow forwarding process.
And S302, monitoring the state of the flow forwarding process in real time through a standby process, wherein the shared message memory area is created by the standby process, and both the standby process and the flow forwarding process can access the shared message memory area.
And S303, after monitoring that the state of the flow forwarding process is abnormal through the standby process, determining a CPU (central processing unit) used when the flow forwarding process forwards the message.
S304, the standby process uses the CPU to forward the message in the shared message memory area.
In the embodiment of the invention, the message in the shared message memory area is forwarded through the flow forwarding process, the state of the flow forwarding process is monitored in real time in the process of forwarding the message in the shared message memory area through the flow forwarding process through the standby process, after the abnormal state of the flow forwarding process is monitored, the CPU used when the flow forwarding process forwards the message is determined, and the determined CPU is used for forwarding the message in the shared message memory area. Compared with the prior art, after the state of the flow forwarding process is abnormal, the standby process forwards the message in the shared message memory area by using the CPU used when the flow forwarding process forwards the message, so that the forwarding of the message is not interrupted, and the reliability of message forwarding can be improved.
When the message is forwarded in the embodiment of the invention, the shared message memory area is created by the bypass process, and firstly, the bypass process is started to create the shared message memory area and initialize the shared message memory area. And starting to forward the message after a series of initialization operations are carried out.
It should be noted that after the bypass process creates the shared message memory area and before forwarding the message, the CPU used by the traffic forwarding process when forwarding the message may be determined by reading the configuration file of the CPU used by the traffic forwarding process when forwarding the message, and the CPU is used to forward the message.
When the bypass process forwards the message, the CPU used when the flow forwarding process forwards the message is used for forwarding, so that the CPU resource is not occupied additionally, and the CPU resource can be saved.
In addition, the shared message memory area is created by the bypass process, so that the shared message memory area can be normally used when the state of the flow forwarding process is abnormal.
In the process of forwarding the message in the shared message memory area by the bypass process, the traffic forwarding process is started, and a registration message is sent to the bypass process through a registration mechanism, where the registration message carries a CPU identifier, such as a CPU ID (Identity Document, identification number), of a CPU used when the traffic forwarding process forwards the message.
After the flow forwarding process is started, the shared message memory area created by the standby process needs to be determined, and when the forwarding message is switched to the flow forwarding process from the bypass process, the flow forwarding process forwards the message in the determined shared message memory area.
After the flow forwarding process is started, a registration message can be sent to the bypass process, and the registration message is used for triggering the bypass process to stop forwarding the message. After receiving the registration message, the bypass process stops forwarding the message in the shared message memory area, and after the packet receiving and sending queue finishes processing the remaining message, the bypass process can send a registration response message to the traffic forwarding process, wherein the registration response message is used for triggering the traffic forwarding process to forward the message.
Correspondingly, after receiving the registration response message, the flow forwarding process takes over the network card to receive and transmit the packet queue immediately and starts to forward the message.
It should be noted that, when the forwarding of the packet is switched from the bypass process to the traffic forwarding process, the time can reach the ms level due to the switching between the software, so that the reliability of the packet forwarding can be improved.
In the process of forwarding the message by the flow forwarding process, the bypass process can monitor the state of the flow forwarding process in real time, and if the abnormal state of the flow forwarding process is monitored, a CPU used when the flow forwarding process forwards the message is determined, and the CPU is used for forwarding the message in the shared message memory area.
It should be noted that, after the traffic forwarding process state is recovered to normal from abnormal, the CPU used in forwarding the packet may be different from the CPU used in forwarding the packet last time, and therefore, when the traffic forwarding process state is abnormal next time, the bypass process needs to determine the CPU used in forwarding the packet by the traffic forwarding process once again.
In an embodiment, the bypass process may monitor the state of the traffic forwarding process by using a netlink connector ns mechanism, and when the state of the traffic forwarding process is abnormal, the netlink connector ns mechanism sends a condition semaphore to the bypass process.
The registration message sent by the traffic forwarding process to the bypass process may carry a CPU identifier of a CPU used by the traffic forwarding process when forwarding traffic, and after receiving the conditional semaphore, the bypass process binds the corresponding CPU to continue forwarding the message according to the CPU identifier of the registration message.
In another embodiment, the bypass process may further determine that the traffic forwarding process does not forward the packet in the shared packet memory area within a preset time length, so as to determine that the state of the traffic forwarding process is abnormal.
Because the switching from the flow forwarding process to the bypass process is the switching between the software, the switching time can reach ms level, and the flow forwarding process and the bypass process share the message memory area, so that the message is not lost at the moment of switching, and the message forwarding reliability can be improved.
In addition, the bypass process can detect other abnormal forwarding states of the traffic forwarding process, such as deadlock, deadlock and the like, by checking the head and tail registers of the network card packet receiving queue, and at the moment, the traffic forwarding process can be manually quitted and switched to the bypass process until the traffic forwarding process is recovered to be normal again.
In a possible implementation manner, after the state of the traffic forwarding process is recovered to normal from an exception, the shared message memory area created by the standby process needs to be determined, and when the forwarding message is switched from the bypass process to the traffic forwarding process, the traffic forwarding process forwards the message in the determined shared message memory area.
For ease of understanding, specific examples are set forth below.
