Abstract
Description
Technical Field
[0001] This invention relates to the field of communication technology, and more specifically, to a method and related apparatus for transmitting congestion status. Background Technology
[0002] In the prior art, when implementing flow control functions, a congestion state table is often maintained to store the congestion state of the receiving module. Based on this, the memory unit can determine whether the receiving module is congested through the congestion state table, and send the current congestion state to the media access controller when the congestion state changes.
[0003] However, after the receiving module restarts and enables flow control, the media access controller often cannot obtain the current congestion status of the receiving module because the congestion state has not changed. To solve this problem, existing technologies often use the central processing unit to actively modify the congestion state table, thereby triggering the memory unit to send the current congestion status to the media access controller. However, since this method requires the central processing unit to perform read and write operations on the congestion state table, there may be atomic operation problems. Summary of the Invention

[0007] Obtain the status detection trigger event for the target receiving module;
[0008] If the current flow control function state corresponding to the target receiving module is different from the target pending flow control function state corresponding to the target receiving module, then a first congestion state is sent to the media access controller according to the target pending flow control function state, and the current flow control function state is updated according to the target pending flow control function state.
[0009] The first congestion state is used to characterize the congestion state of the target receiving module, and the target pending flow control function state is set by the central processing unit according to the flow control function setting instruction sent by the user.

[0014] In an optional implementation, the method further includes:
[0015] If both the current flow control function state corresponding to the target receiving module and the target pending flow control function state corresponding to the target receiving module are enabled, then the current congestion state of the target receiving module is determined based on the current congestion count corresponding to the target receiving module and the preset congestion waterline.
[0016] Based on the current congestion state and the second congestion state corresponding to the target receiving module, determine whether to update the second congestion state; wherein, the second congestion state is the congestion state corresponding to the target receiving module stored in the memory unit;
[0017] If it is determined that the second congestion state needs to be updated, the second congestion state is updated to the current congestion state.
[0018] In an optional implementation, determining whether to update the second congestion state based on the current congestion state and the second congestion state corresponding to the target receiving module includes:
[0019] If the current congestion state is different from the second congestion state, then it is determined that the second congestion state should be updated.
[0020] In an optional implementation, the method further includes:

[0022] In an optional implementation, sending a first congestion status to the media access controller based on the target pending flow control function status includes:
[0023] If the target flow control function is in a closed state, the unobstructed state is sent to the media access controller as the first congestion state.
[0024] The step of updating the current flow control function status of the target based on the target pending flow control function status includes:
[0025] Change the current flow control function status of the target to the off state.
[0026] Secondly, the present invention provides a congestion state transmission device applied to a memory unit, the memory unit being connected to a media access controller and a central processing unit, respectively. The memory unit stores the current flow control function state and the pending flow control function state corresponding to each receiving module, and at the initial operating moment, both the current flow control function state and the pending flow control function state are in a closed state; the device includes:
[0027] The acquisition module is used to acquire status detection trigger events for the target receiving module;
[0028] The sending module is configured to send a first congestion status to the media access controller according to the target pending flow control function status if the target current flow control function status corresponding to the target receiving module is different from the target pending flow control function status corresponding to the target receiving module, and update the target current flow control function status according to the target pending flow control function status.

[0032] Fifthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the congestion state transmission method as described in any of the foregoing embodiments.
[0033] The congestion state sending method and related apparatus provided in this invention include a memory unit storing the current flow control function state and the pending flow control function state corresponding to each receiving module. In the initial operating state, both the current flow control function state and the pending flow control function state are in a disabled state. The pending flow control function state can be set by the central processing unit (CPU) according to a flow control function setting instruction sent by the user. When the memory unit receives a state detection trigger event for a target receiving module, it can determine whether the target current flow control function state corresponding to the target receiving module is the same as the target pending flow control function state. If they are different, a first congestion state is sent to the media access controller based on the target pending flow control function state. With this method, after the receiving module restarts and enables flow control, the CPU only needs to modify the pending flow control function state before the memory unit can send the first congestion state to the media access controller. Therefore, the CPU does not need to modify the congestion state table, thus ensuring that atomic operation problems do not occur.

[0045] Optionally, the memory unit stores the current flow control function status and the pending flow control function status corresponding to each receiving module, and at the initial running time, both the current flow control function status and the pending flow control function status are in the off state.
[0046] Optionally, the receiving module may include a receiving port and a receiving queue.
[0047] Optionally, the current flow control function state and the pending flow control function state can be stored in a memory unit in the form of a state table.
[0048] Furthermore, in Figure 1 On this basis, Figure 2Please refer to the block diagram of the memory unit 100 provided in the embodiment of this application. Figure 2 The memory unit 100 includes a memory 101, a processor 102, and a communication module 103. The memory 101, processor 102, and communication module 103 are electrically connected directly or indirectly to each other to achieve data transmission or interaction.

[0051] The communication module 103 is used to establish a communication connection between the server and other communication terminals via the network, and to send and receive data via the network.
[0052] It should be understood that, Figure 1 , Figure 2 The structure shown is only a schematic diagram of the electronic device and memory unit; the electronic device and memory unit may also include more than [other components]. Figure 1 , Figure 2 The more or fewer components shown, or having the same Figure 1 , Figure 2 The different configurations shown. Figure 1 , Figure 2 The components shown can be implemented using hardware, software, or a combination thereof.
[0053] The following is based on the above. Figure 1 The memory unit 100 in the diagram serves as the execution entity. The congestion state transmission method provided in this application embodiment will be described exemplarily with reference to the flowchart. Specifically, Figure 3 For a flowchart illustrating the congestion state transmission method provided in this application embodiment, please refer to [link / reference]. Figure 3The method includes:
[0054] Step S20: Obtain the status detection trigger event for the target receiving module.
[0055] Optionally, the status detection triggering event includes message triggering and timer scan triggering.
[0056] Step S21: If the current flow control function state of the target corresponding to the target receiving module is different from the target pending flow control function state of the target receiving module, then send the first congestion state to the media access controller according to the target pending flow control function state, and update the current flow control function state of the target according to the target pending flow control function state.
[0057] The first congestion state is used to characterize the congestion state of the target receiving module, and the target pending flow control function state is set by the central processing unit according to the flow control function setting instruction sent by the user.
[0058] Optionally, the flow control function setting instructions may include enable instructions and disable instructions.
[0059] In this embodiment, the user can send an enable or disable command for the flow control function of the target receiving module. The central processing unit (CPU) can then modify the state of the target's pending flow control function according to the enable or disable command. In this embodiment, since both the target's current flow control function and the target's pending flow control function are disabled in the initial operating state, if the user enables the flow control function for the target receiving module, the CPU can modify the state of the target's pending flow control function to be enabled.
[0060] Optionally, if the memory unit obtains a status detection trigger event for the target receiving module at this time, it can determine that the target's current flow control function and the target's pending flow control function are different. Based on this, the memory unit can send the first congestion status to the media access controller.
[0061] Understandably, in the prior art, after the receiving module restarts and the flow control function is enabled, the central processing unit needs to modify the congestion state table before it can trigger the memory unit to send the current congestion state to the media access controller. However, since the state detection trigger event may also require modification of the congestion state table, there will be certain atomic operation problems. However, the congestion state sending method provided in this application embodiment does not require the central processing unit to modify the congestion state table, and the memory unit can successfully send the first congestion state to the media access controller, thus ensuring that there will be no atomic operation problems.
[0062] The congestion state sending method provided in this application embodiment stores the current flow control function state and the pending flow control function state corresponding to each receiving module in the memory unit. In the initial running state, both the current flow control function state and the pending flow control function state are in a closed state. The pending flow control function state can be set by the central processing unit (CPU) according to the flow control function setting instruction sent by the user. When the memory unit obtains a state detection trigger event for the target receiving module, it can determine whether the target current flow control function state corresponding to the target receiving module is the same as the target pending flow control function state corresponding to the target receiving module. If they are different, a first congestion state is sent to the media access controller based on the target pending flow control function state. With this method, after the receiving module restarts and enables flow control, the CPU only needs to modify the pending flow control function state before the memory unit can send the first congestion state to the media access controller. Therefore, the CPU does not need to modify the congestion state table, thus ensuring that atomic operation problems do not occur. Optionally, the difference between the target current flow control function state and the target pending flow control function state corresponding to the target receiving module may include the following two situations.
[0063] Firstly, at the initial running moment, both the target's current flow control function status and the target's pending flow control function status are in the off state. However, when the user enables the flow control function for the target receiving module, the central processing unit modifies the target's pending flow control function status to the on state.
[0064] Secondly, during normal operation, both the current flow control function status and the target pending flow control function status are enabled. However, if the user disables the flow control function for the target receiving module, the central processing unit will change the target pending flow control function status to disabled.
[0065] Understandably, since different target pending flow control function states indicate whether the flow control function still needs to operate normally, the memory unit needs to send the corresponding first congestion state according to different target pending flow control function states.
[0066] In one possible implementation, if the target's current flow control function is in a disabled state and the target's pending flow control function is in an enabled state, it means that the flow control function needs to be enabled later. Therefore, the memory unit can send the target receiving module's current actual congestion status to the media access controller.
[0067] Specifically, if the target flow control function is enabled, the memory unit can determine the current congestion state of the target receiving module based on the current congestion count and the preset congestion waterline, and send the current congestion state as the first congestion state to the media access controller.
[0068] Optionally, the current congestion count can be data such as the percentage of buffer usage, and the congestion watermark can be congestion threshold data, etc.
[0069] In one example, if the current congestion count exceeds the congestion threshold, the current congestion state of the target receiving module can be determined as congested, and this congested state can be sent to the media access controller as the first congestion state.
[0070] In another example, if the current congestion count does not exceed the congestion threshold data, the current congestion state of the target receiving module can be determined to be a smooth state, and this smooth state is sent to the media access controller as the first congestion state.
[0071] In this embodiment, the memory unit also needs to update the current flow control function state of the target according to the target's pending flow control function state, that is, modify the target's current flow control function state to the enabled state.
[0072] In another possible implementation, if the target's current flow control function is enabled, while the target's pending flow control function is disabled, it means that the flow control function needs to be disabled later. In this case, the media access controller needs to release the flow control from the peer device. Therefore, the memory unit can ignore the actual congestion status of the target receiving module and directly assume that the target receiving module is in a smooth state.
[0073] Specifically, if the target flow control function is in the off state, the memory unit sends the unobstructed state as the first congestion state to the media access controller.
[0074] In this embodiment, the memory unit also needs to update the current flow control function state of the target according to the target's pending flow control function state, that is, modify the target's current flow control function state to the off state.
[0075] Optionally, since the memory unit updates the current flow control function state of the target based on the state of the target pending flow control function after sending the first congestion state, the current flow control function state of the target receiving module and the state of the target pending flow control function of the target receiving module may be the same after the memory unit obtains the state detection trigger event for the target receiving module, that is, both are in the open state or both are in the closed state.
[0076] Understandably, if both the current flow control function status and the target pending flow control function status are closed, it means that the flow control function is always closed and no other operation is required; if both the current flow control function status and the target pending flow control function status are open, it means that the flow control function is open, so it is necessary to detect the current congestion status.
[0077] Optionally, if both the current flow control function state corresponding to the target receiving module and the pending flow control function state corresponding to the target receiving module are enabled, the memory unit can determine the current congestion state of the target receiving module based on the current congestion count corresponding to the target receiving module and the preset congestion waterline.
[0078] Optionally, the memory unit may store a congestion state table to store the second congestion state corresponding to each receiving module.
[0079] Based on this, the memory unit can determine whether to update the second congestion state according to the current congestion state and the second congestion state corresponding to the target receiving module, and if it is determined that the second congestion state should be updated, the second congestion state is updated to the current congestion state.
[0080] In one possible implementation, if the current congestion state is different from the second congestion state, it indicates that the congestion state of the target receiving module has changed, and therefore it can be determined to update the second congestion state.
[0081] Optionally, the memory unit may also send the current congestion status to the media access controller every preset time interval when both the current flow control function status corresponding to the target receiving module and the pending flow control function status corresponding to the target receiving module are enabled.
[0082] Optionally, a timer can be set in the memory unit to record the time interval for sending the current congestion status. Based on this, the memory unit can periodically send the current congestion status to the media access controller when the time interval between the current moment and the moment when the current congestion status was last sent reaches the preset duration.
[0083] In this embodiment, the preset duration can be set according to the actual application situation, and this application does not make specific limitations on it.
[0084] To perform the corresponding steps in the above embodiments and various possible methods, an implementation of a congestion state transmission device is given below. Further, please refer to... Figure 4 , Figure 4 This is a functional block diagram of a congestion status sending device provided in an embodiment of the present invention.
