Description
Technical Field
The present application belongs to the technical field of network communication, and in particular, relates to a method, an apparatus, a network device, and a storage medium for improving stability of a network device.
Background
On the network equipment, the connection (Link) state of the port has two states, namely, a connection state (up) and a disconnection state (down). When the connection state of the port changes, the CPU needs to be notified immediately, and then the CPU notifies the upper layer service software, so that the upper layer service software executes operations corresponding to the change of the connection state, for example, switching service traffic and stopping sending and receiving packets, and also reminds a user whether to perform some processing on a physical link. Frequent changes in connection state within a short time increase system overhead and reduce system stability. To improve system stability, software typically has a delayed reporting mechanism. The delayed reporting mechanism is that after the port generates a state change event, the port is confirmed in a certain period, if the connection state is still maintained in the changed state, the connection state is notified to the upper layer service software for processing, otherwise, the change is ignored.
When the connection state of the port changes up/down, two actions are triggered: 1. operations such as clearing/modifying registers or table entries and the like need to be actively carried out on hardware; 2. meanwhile, the event that the connection state changes is immediately notified to the upper layer service software, and the upper layer service software also needs to do some operations such as modifying registers or entries. The setting of hardware and the setting of software may occur simultaneously, and there is a possibility that the settings conflict. There will be a certain probability that this will cause some unknown problems, such as the actual value of a certain register being different from the expected value, etc. Particularly, in an environment where the port connection state up/down frequently occurs, the possibility of collision is increased, a hardware problem is easily caused, and it is difficult to recover from ambiguity as to which settings are not specified.
Although, the delayed reporting mechanism may enable the software to perform the software setting after the hardware setting is completed after the connection status changes, thereby alleviating the problem. However, the following problems remain:
1, some service software needs to sense the change of the port connection state as soon as possible, especially the state change from up to down, and the service needs to switch flow, calculate a path and the like as soon as possible, but a delayed reporting mechanism is usually used when the state change from down to up.
2, individual setup requires that the port be kept in either the up or down state for execution to be reliable. The setting is easier to keep in the down state, and the port can be kept in the down state all the time only by actively modifying the corresponding register by software before the setting. However, the up state is usually affected by the physical link and may be passively changed during the setting process, so that maintaining the up state is not easy to be realized.

In view of this, an object of the present application is to provide a method, an apparatus, a network device and a storage medium for improving the stability of a network device, so as to solve the problem that software perception is slow from an up state to a down state in a scheme of a delayed reporting mechanism, and the problem that individual settings need to be executed in a specific connection state to ensure reliability.

In order to solve the problems of the current delayed reporting mechanism, the application provides a method for improving the stability of network equipment, when the connection state of a sensing physical link is changed, hardware keeps the port connection state unchanged, upper layer service software is informed to process the change, after the upper layer service software completes corresponding operation, the port state of the hardware side is changed, so that the problems that the software sensing from an up state to a down state is slow in the scheme of the delayed reporting mechanism and that individual setting needs to be executed in a specific connection state to ensure the reliability can be effectively avoided. The method for improving the stability of the network device provided by the embodiment of the present application will be described with reference to fig. 1.
Step S101: when detecting that the connection state of the physical interface transceiver side changes, notifying upper-layer service software that the connection state of the physical interface transceiver side changes, so that the upper-layer service software executes an operation corresponding to the change of the connection state.
When detecting that a connection state of a physical interface transceiver (PHY) side changes, a processor (e.g., a Central Processing Unit, CPU) notifies upper layer service software that the connection state of the PHY side changes, so that the upper layer service software executes an operation corresponding to the change of the connection state, for example, operations such as service switching and table entry deletion.
As an embodiment, whether the connection state of the physical interface transceiver side changes is detected by detecting whether a notification of the change of the connection state of the physical interface transceiver side sent from the Media Access Controller (MAC) side is received, and when the notification of the change of the connection state of the physical interface transceiver side sent from the MAC side is received, it is characterized that the change of the connection state of the physical interface transceiver side is detected. Usually, the change of the port connection state is firstly sensed by the PHY side, when a connection state event occurs at the PHY side, the PHY side notifies the processor through an interrupt mode through a Media Access Controller (MAC) side, and after receiving the notification, the processor notifies the PHY side of the upper layer service software that the connection state changes.
In still another embodiment, the detection of the change of the connection state of the physical interface transceiver side is performed by detecting whether the connection state of the physical interface transceiver side changes from up to down or from down to up, and the detection of the change of the connection state of the physical interface transceiver side is characterized when the detection of the change of the connection state of the physical interface transceiver side changes from up to down or from down to up. In this embodiment, the processor senses whether the connection state of the physical interface transceiver side changes by detecting whether the connection state of the physical interface transceiver side changes from up to down or from down to up in real time through the media access controller.
Step S102: and when the upper-layer service software finishes the operation corresponding to the change of the connection state, controlling the connection state of the media access controller side to be changed into a state consistent with the connection state of the physical interface transceiver side.
And when the upper-layer service software finishes the operation corresponding to the change of the connection state, controlling the connection state of a Media Access Controller (MAC) side to be changed into a state consistent with the connection state of the physical interface transceiver side. That is, in the embodiment of the present application, the connection state of the MAC side does not change due to the change of the connection state of the PHY side, and the connection state of the MAC side is controlled to change until the upper layer service software completes the operation corresponding to the change of the connection state, so that the connection state of the MAC side is consistent with the connection state of the PHY side. Usually, the change of the port connection state is firstly sensed by the PHY side, then the connection state of the MAC side is changed in a linkage manner, and then the MAC side notifies upper-layer service software on a processor to process the change in an interrupt manner. Before detecting that the connection state of the physical interface transceiver side changes, the connection state of the media access controller side is controlled to be a forced state, so that the connection state of the media access controller side does not change due to the change of the connection state of the physical interface transceiver side; and then after the PHY side generates an event of connection state change, the connection state of the MAC side is forced to be kept unchanged, the event of connection state change generated by the PHY side is notified to the processor, after the upper-layer service software running on the processor executes the operation corresponding to the connection state change, the forced connection state of the MAC side is controlled to be changed to be consistent with the PHY, and the setting of hardware is triggered. Therefore, the settings are linearly executed, the processing sequence of software and hardware can be effectively ensured, the problem caused by multiple operations in an unstable state is prevented, meanwhile, the service perception and the processing speed are not influenced, the stability of network equipment can be improved, and the service is prevented from being influenced by network oscillation.
For convenience of understanding, a specific embodiment of switching the connection state of the ports shown in fig. 2 is described as an example. Firstly, the initialization process is carried out, the network equipment is started, and after the PHY side finds the up state, the MAC side is set to the up state of a forced state (forceLink), so that the PHY side and the MAC side are both in the up state. Then waiting for the state of the PHY side to be changed into down; then, the PHY side is processed to generate down, after the PHY side generates down event, the MAC side informs the upper layer service software on the processor to set through an interruption mode, and after the upper layer service software is set, the MAC side is set to be in the down state of Force Link, and the hardware is triggered to start setting; then start to wait for the state of the PHY side to change to up; and then the PHY side generates up processing, when the PHY side generates up event, the MAC side informs the upper layer service software on the processor to set in an interruption mode, and after the upper layer service software is set, the MAC side is set to be in the up state of Force Link, and the hardware is triggered to start setting. The process then waits for the PHY side to change to down, and so on.
According to the method and the device, when the connection state of the physical link changes, the linkage of the PHY side and the MAC side is separated. When detecting that the connection state of the PHY side changes, notifying upper layer service software to perform equipment, and meanwhile, forcibly keeping the connection state of the MAC side unchanged, so that the connection state of the MAC side does not change due to the change of the connection state of the PHY side; after the upper-layer service software is operated, the connection state of the MAC side is changed to keep consistent with that of the PHY side, so that the settings are linearly executed, the processing sequence of the software and the hardware can be effectively ensured, the problem caused by multiple operations in an unstable state is prevented, the service perception and the processing speed are not influenced, the stability of network equipment can be improved, and the service is prevented from being influenced by network oscillation.
