Detailed Description

Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

The embodiment of the application provides a queue management method for a network card, aiming at the problems that in the related art, in a cloud computing virtualization scene, the number of network interfaces corresponding to the network card is increased, and queue allocation is performed in a fixed allocation mode, so that when a queue corresponding to the network interface is in an idle state, the network interface cannot be allocated to other queues for use, and an idle queue corresponding to the network interface cannot be allocated to other network interfaces for use, so that queue resources are wasted, and the performance of the network card is reduced.

The method for managing the queue of the network card according to the embodiment of the application comprises the steps of determining a base address of a virtual network interface to be created in a preset queue mapping table according to an identifier of the virtual network interface to be created included in a virtual network interface creation request and the maximum queue number supported by each virtual network interface corresponding to the network card when the virtual network interface creation request corresponding to the network card is acquired and the number of idle queues corresponding to the network card is greater than 0, traversing a queue state array group corresponding to the network card, sequentially determining a queue with a queue state being an idle state as a queue to be allocated according to the number of the request queues, sequentially filling the identifier of each queue to be allocated into the preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table, and further sequentially filling the identifier of the queue to be allocated and the number of the queue to be allocated, and updating the queue state array and the number of free queues. Therefore, by presetting a queue mapping table in the network card and carrying out dynamic queue management through the queue mapping table, the idle queue corresponding to the network card is flexibly distributed to each network interface, so that queue resources in the network card are fully utilized, and the performance of the network card is improved.

The following describes in detail a queue management method, apparatus, electronic device, storage medium, and computer program for a network card provided in the present application with reference to the drawings.

Fig. 1 is a flowchart illustrating a method for managing a queue of a network card according to an embodiment of the present application.

As shown in fig. 1, the method for managing the queue of the network card includes the following steps:

step 101, acquiring a virtual network interface creating request corresponding to a network card, wherein the virtual network interface creating request includes an identifier of a virtual network interface to be created and the number of request queues corresponding to the virtual network interface to be created.

It should be noted that the queue management method for the network card in the embodiment of the present application may be executed by the queue management method device for the network card in the embodiment of the present application. The network card queue management method according to the embodiment of the present application may be configured in any electronic device, so as to execute the network card queue management method according to the embodiment of the present application.

As a possible implementation manner, the method for managing the queue of the network card in the embodiment of the present application may be executed by the network card in the electronic device. As shown in fig. 2, a schematic structural diagram of an electronic device including a network card according to an embodiment of the present application is provided, where the electronic device includes the network card, and the network card mainly includes two parts, namely a network card logic and management software. The network card logic may be implemented by a Field Programmable Gate Array (FPGA), and the management software may run on a Central Processing Unit (CPU) on the network card. It should be noted that, in the present application, the queue inside the network card and the preset queue mapping table (hardware part) may be implemented by a network card logic, and the queue management method (software part) of the network card may be implemented by management software.

The network card may be any network card having a plurality of network interfaces. For example, it may be an intelligent network card that supports the creation of virtual network interfaces.

The virtual network interface creation request may be sent to the network card by an application program in the electronic device where the network card is located, so as to create a network interface used when the application program sends and receives a data packet.

The identifier of the virtual network interface to be created may be specified when the application program sends a virtual network interface creation request; or the management software of the network card may generate the identifier according to the created virtual network interface after acquiring the virtual network interface creation request, and the identifier of the virtual network interface to be created is different from the identifier of the created virtual network interface.

It should be noted that the identifier of the virtual network interface is information that can uniquely determine the virtual network interface, and the identifiers of the virtual network interfaces are different from each other. Optionally, a format of the identifier of the virtual network interface may be preset, so as to allocate a legal identifier to the newly-built virtual network interface when the virtual network interface is newly built. For example, the identities of the virtual network interfaces may be NET0, NET1, NET2, and so on.

The number of request queues corresponding to the virtual network interface to be created refers to the number of queues that are allocated to the virtual network interface to be created according to the current needs set by the application program according to actual needs.

In this embodiment of the present application, the management software in the network card may obtain, in real time, a virtual network interface creation request sent by an application program in the electronic device, and perform parsing on the virtual network interface creation request to determine an identifier of a virtual network interface to be created included in the virtual network interface creation request and a number of request queues corresponding to the virtual network interface to be created.

And 102, under the condition that the number of idle queues corresponding to the network card is greater than 0, determining a base address of the virtual network interface to be created in a preset queue mapping table according to the identifier of the virtual network interface to be created and the maximum number of queues supported by each virtual network interface corresponding to the network card.

In the embodiment of the present application, because the number of network interfaces in the network card is large in the cloud computing virtualization environment, when the fixed allocation manner shown in fig. 3 is adopted to equally allocate the queues in the network card to each network interface, the queues in the network card are not sufficient, and when there is an idle queue in a network interface, the idle queue cannot be allocated to other network interfaces for use, so that queue resources are wasted. The quee _ base refers to a base address corresponding to a corresponding network interface, and the quee _ offset refers to an offset address corresponding to a queue.

When the on-demand allocation method shown in fig. 4 is used to allocate the queues in the network card to the network interfaces, the queues are directly exposed to the application program for use, and therefore the queues allocated to the same network interface need to be physically continuous, so that after the network interfaces are created and deleted for many times, a "hole" is easily formed in the queue space, and thus the queue resources are wasted. For example, as shown in fig. 4, initially, 4 network interfaces NET0, NET1, NET2, NET3 are created in sequence, and each network interface occupies 2 queues. Then, the network interface NET1 is deleted, releasing the Queue2/3 Queue, and then the network interface NET3 is deleted, releasing the Queue6/7 Queue. At this time, Queue2/3 and Queue6/7 are in idle state, but are not physically continuous, if a network interface NET4 containing 4 queues needs to be created subsequently, the creation will fail in a continuous allocation mode, although the number of idle queues inside the network card is greater than or equal to 4, thereby wasting Queue resources.

Therefore, in the embodiment of the present application, in order to fully utilize the queue resources in the network card, a queue mapping table may be preset, so as to store the allocation relationship between the virtual network interfaces and the queues through a preset queue mapping table, and for each virtual network interface, a continuous space may be allocated in the preset queue mapping table to store the mapping relationship between the virtual network interface and the queues; when the application program accesses the queues through the queue mapping table, the queues corresponding to the same virtual network interface are continuous in the preset queue mapping table for the application program regardless of whether the queues corresponding to the virtual network interfaces are continuous physically, so that the physically discontinuous queues can be successfully allocated to the same virtual network interface, and queue resources are fully utilized.

The maximum number of queues supported by each virtual network interface refers to a mapping position with a fixed size configured for each virtual network interface in the network card in a preset queue mapping table, and can reflect the maximum number of queues that each virtual network interface can allocate. For example, the maximum number of supported queues allocated to each virtual network interface in the network card in the preset queue mapping table may be 64, that is, each virtual network interface may be allocated with 64 queues at most.

It should be noted that, assuming that the network card includes 1000 queues, 1 queue in the preset queue mapping table needs to be represented by 10 bytes, and if the maximum number of queues supported by each virtual network interface is 64 and the network card can support 128 virtual network interfaces at most, 10 bits × 64 × 128 — 80Kb of storage resources are needed to implement the preset queue mapping table, so that the resource occupation amount is small.

The base address of the virtual network interface to be created in the preset queue mapping table refers to a starting address of the virtual network interface to be created in the preset queue mapping table, that is, a storage address of a first queue corresponding to the virtual network interface to be created.

As a possible implementation manner, the number of idle queues corresponding to the network card may be stored in the management software, so that when the management software obtains a virtual network interface creation request, the management software may first determine whether the network card currently has an idle queue according to the number of idle queues to determine whether to respond to the creation request. Therefore, when the number of the idle queues corresponding to the network card is greater than 0, that is, when the idle queues currently exist in the network card, the creation request of the virtual network interface is responded, and the mapping relation between the new virtual network interface and the idle queues is generated in the preset queue mapping table, so that the idle queues are allocated to the new virtual network interface for use, and the creation of the virtual network interface is completed. Therefore, the base address of the virtual network interface to be created in the preset queue mapping table can be determined according to the identifier of the virtual network interface to be created and the maximum number of queues supported by each virtual network interface, so that the mapping relationship between the virtual network interface to be created and the queue allocated to the virtual network interface to be created can be stored according to the base address.

Optionally, the identifier of the virtual network interface to be created may be used to indicate an arrangement order of the virtual network interface to be created in the preset queue mapping table, so that the base address of the virtual network interface to be created in the preset queue mapping table may be determined according to the identifier of the virtual network interface to be created and the maximum number of queues supported by each virtual network interface. For example, the identifiers of the virtual network interfaces are NET0, NET1, NET2, NET3, … …, where NET0 is the 1 st virtual network interface in the preset queue mapping table, NET1 is the 2 nd virtual network interface in the preset queue mapping table, and so on; if the identifier of the virtual network interface to be created is NET1, the maximum number of queues supported by each virtual network interface is 64, and the addresses of each storage unit corresponding to the preset queue mapping table are 0, 1, 2, 3, … …, and so on; thus, it can be determined that the base address of the virtual network interface NET1 to be created in the preset queue mapping table is 64.

As a possible implementation manner, if the number of idle queues corresponding to the network card is 0, it may be determined that no idle queue exists in the network card at present, and the virtual network interface creation request may not be responded, and a prompt message of creation failure is sent to the application program that initiated the request, and a failure reason is reported.

Step 103, traversing the queue state array corresponding to the network card, and determining the queue with the queue state being an idle state as a queue to be allocated in sequence until the traversal of the queue state array is completed, or until the number of the queues to be allocated is equal to the number of the request queues.

The queue state may include a use state and an idle state. The use state means that the queue is currently used by the network interface; an idle state, meaning that the queue is not currently being used by any network interface.

In the embodiment of the application, a queue state array may be maintained in management software for storing a queue state of each queue in the network card, so that when an idle queue exists in the network card, the queue state array corresponding to the network card may be traversed to determine, in sequence, each queue whose queue state is the idle state as a queue to be allocated, and allocate the queue to be allocated to a virtual network interface to be created, so as to complete creation of a new virtual network interface.

As a possible implementation manner, if the number of idle queues corresponding to the network card is less than the number of request queues, all queues in an idle state may be determined as queues to be allocated, and the number of actually allocated queues is returned to the application program that sends the request after the virtual network interface is created; if the number of the idle queues corresponding to the network card is greater than or equal to the number of the request queues, the idle queues can be determined as queues to be allocated in sequence from the first idle queue in the queue state array until the number of the queues to be allocated is equal to the number of the request queues.

For example, as shown in fig. 5, assuming that the number of request queues corresponding to the to-be-created virtual network interface NET1 is 4, and there are free queues Queue3, Queue4, Queue6, and Queue8 in the network card, free queues Queue3, Queue4, Queue6, and Queue8 may be determined as queues to be allocated.

And step 104, sequentially filling the identifier of each queue to be allocated into a preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table.

The identifier of the queue to be allocated may be a physical number of the queue to be allocated in the network card. For example, as shown in FIG. 5, the identification of Queue0 can be 0, the identification of Queue1 can be 1, and so on.

In this embodiment of the present application, when the queue mapping table is preset, a preset value may be filled in each storage unit corresponding to the preset queue table, for example, as shown in fig. 5, the preset value may be-1. After determining the queues to be allocated, filling the identifier of the 1 st queue to be allocated into a storage unit corresponding to the base address in a preset queue mapping table, filling the identifier of the 2 nd queue to be allocated into a storage unit which is positioned behind the storage unit corresponding to the base address and adjacent to the storage unit corresponding to the base address in the preset queue mapping table, and so on until the identifiers of all queues to be allocated are filled into the preset queue mapping table, thereby generating the corresponding relationship between the virtual network interface to be created and each queue to be allocated in the preset queue mapping table.

For example, as shown in fig. 5, after determining that the queues to be allocated corresponding to the virtual network interfaces NET1 to be created are Queue3, Queue4, Queue6 and Queue8, respectively, identifier 3 of Queue3, identifier 4 of Queue4, identifier 6 of Queue6, and identifier 8 of Queue8 may be sequentially filled in a preset Queue mapping table from a base address corresponding to NET 1.

And 105, updating the queue state array and the number of the idle queues according to the identifiers of the queues to be distributed and the number of the queues to be distributed.

In the embodiment of the application, after the identifier of the queue to be allocated is filled in the preset queue mapping table, the corresponding relationship between the virtual network interface to be created and the queue to be allocated is established, that is, each queue to be allocated is already used by the virtual network interface to be created, and the queue state of each queue to be allocated changes, so that the queue state array and the number of idle queues need to be updated, so as to ensure that the queue state data and the number of idle queues can accurately represent the use condition of each queue in the network card.

As a possible implementation manner, the queue state array may include a corresponding relationship between an identifier of each queue and a queue state, so that after the queue to be allocated is allocated to the virtual network interface to be created, the queue state corresponding to the queue to be allocated may be searched and updated by using the identifier of the queue to be allocated as an index, and the number of free queues may be updated. That is, in a possible implementation manner of this embodiment of the present application, step 105 may include:

updating the queue state corresponding to the identifier of each queue to be allocated in the queue state array to be a use state according to the identifier of the queue to be allocated, and associating the identifier of each queue to be allocated with the identifier of the virtual network interface to be created;

and determining the difference between the number of the idle queues and the number of the queues to be distributed as the updated number of the idle queues corresponding to the network card.

In the embodiment of the application, the queue state array may be traversed to update the queue state corresponding to the identifier of each queue to be allocated in the array to the use state, and the identifier of the virtual network interface to be created corresponding to the queue to be allocated may be written into the queue state data, so as to associate the identifier of each queue to be allocated with the identifier of the virtual network interface to be created, so that the queue state array may represent not only the use state of each queue in the network card, but also which network interface each queue is specifically allocated to for use.

In the embodiment of the application, since the queue to be allocated is allocated to the virtual network interface to be created for use, the number of idle queues corresponding to the network card is correspondingly reduced, so that the difference value between the current number of idle queues and the number of queues to be allocated can be determined as the updated number of idle queues.

For example, as shown in fig. 5, assuming that the current free Queue number of the network card is 4, after Queue3, Queue4, Queue6 and Queue8 are allocated to NET1, the Queue states corresponding to Queue3, Queue4, Queue6 and Queue8 may be updated to the use state and the free Queue number may be updated to 0 in the Queue state array.

As a possible implementation manner, step 103-105 in this embodiment may also be performed synchronously, that is, in the process of traversing the queue state array, each idle queue is queried, the idle queue is determined as a queue to be allocated, and at the same time, the queue state corresponding to the queue to be allocated is updated to the use state, and the number of the idle queues is reduced by one; and traversing the next queue in the queue state array until the number of the queues to be distributed is the same as that of the request queues, or the traversal of the queue state array is completed.

In a possible implementation form of the present application, the request may be correspondingly created and a new virtual network interface may be created only when the number of idle queues in the network card is greater than or equal to the number of request queues corresponding to the virtual network interface to be created, so that the created virtual network interface may meet the actual use requirement of the application program, and the reliability of the operation of the network card is further improved while the queue resources are fully utilized.

The queue management method of the network card provided in the embodiment of the present application is further described below with reference to fig. 6.

Fig. 6 is a flowchart illustrating another method for managing a queue of a network card according to an embodiment of the present application.

As shown in fig. 6, the method for managing the queue of the network card includes the following steps:

step 201, obtaining a virtual network interface creation request corresponding to the network card, where the virtual network interface creation request includes an identifier of a virtual network interface to be created and a number of request queues corresponding to the virtual network interface to be created.

The detailed implementation process and principle of step 201 may refer to the detailed description of the above embodiments, and are not described herein again.

Step 202, obtaining the number of idle queues corresponding to the network card.

In the embodiment of the application, the number of idle queues corresponding to the network card can be stored in the management software, so that when a virtual network interface creation request is obtained, assignment of a variable corresponding to the number of idle queues can be obtained, and the assignment of the variable is determined as the number of idle queues corresponding to the network card currently.

Step 203, sending a prompt message of failure of newly building a virtual network interface when the number of the idle queues is less than the number of the request queues.

As a possible implementation manner, if the number of idle queues corresponding to the network card at present is less than the number of request queues, it may be determined that the number of the idle queues is insufficient, and a virtual network interface cannot be newly created, so that a prompt message indicating that a newly created virtual network interface fails may be sent to an application program that sends a request, and a failure reason is sent, so as to ensure that the newly created virtual network interface can meet actual requirements of the application program, and further improve the reliability of the operation of the network card.

And 204, under the condition that the number of the idle queues is determined to be greater than or equal to the number of the request queues, determining the base address of the virtual network interface to be created in the preset queue mapping table according to the identifier of the virtual network interface to be created and the maximum number of the queues supported by each virtual network interface corresponding to the network card.

As a possible implementation manner, if it is determined that the number of idle queues corresponding to the network card currently is greater than or equal to the number of request queues, it may be determined that the current idle queues may meet the requirement of newly building a virtual network interface, so that a virtual network interface may be newly built according to a virtual network interface creation request, the same number of idle queues are allocated to the virtual network interface according to the number of request queues, a mapping relationship between a new virtual network interface and an idle queue is generated in a preset queue mapping table, and creation of the virtual network interface is completed.

It should be noted that, the specific process and implementation principle of determining the base address of the virtual network interface to be created in the preset queue mapping table in step 204 may refer to the detailed description of the foregoing embodiment, and details are not described here.

Step 205, sequentially obtaining the queue state corresponding to each queue in the queue state array.

In the embodiment of the application, after the base address of the virtual network interface to be created in the preset queue mapping table is determined, the queue state array corresponding to the network card may be traversed to determine the current idle queue in the network card, and the idle queue is allocated to the virtual network interface to be created, so that the queue state corresponding to each queue in the queue state array may be sequentially obtained to determine the queue state as the queue in the idle state.

And step 206, determining the current queue as the queue to be allocated under the condition that the queue state corresponding to the current queue is an idle state.

In the embodiment of the application, when the queue state array corresponding to the network card is traversed, if it is determined that the queue state corresponding to the current queue in the queue state array is an idle state, the current queue may be determined as a queue to be allocated, so as to allocate the queue to a virtual network interface to be created. For example, as shown in fig. 5, if the Queue status of Queue3 is idle, Queue3 may be determined as the Queue to be allocated.

And step 207, under the condition that the queue state corresponding to the current queue is the use state, skipping the current queue and acquiring the queue state corresponding to the next queue adjacent to the current queue in the queue state array until the number of the queues to be distributed is equal to the number of the request queues.

In this embodiment of the present application, when traversing the queue state array corresponding to the network card, if it is determined that the queue state corresponding to the current queue in the queue state array is the use state, it may be determined that the current queue cannot be allocated to the virtual network interface to be created, so that the current queue may be directly skipped, and the queue state of the next queue adjacent to the current queue is continuously obtained from the queue state array until the number of queues to be allocated is equal to the number of request queues, and the above traversal process may be completed.

For example, as shown in fig. 5, when NET1 is created, the number of corresponding request queues is 4, and the Queue state of current Queue5 is the use state, then Queue5 may be skipped to obtain the Queue state of Queue6 until the Queue state of Queue8 is determined to be the idle state, and after Queue8 is determined to be the Queue to be allocated, the number of queues to be allocated is determined to be 4, which is the same as the number of request queues, so that traversal of the Queue state array may be stopped.

And step 208, sequentially filling the identifier of each queue to be allocated into a preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table.

Step 209, updating the queue status array and the number of idle queues according to the identifier of the queue to be allocated and the number of the queue to be allocated.

The detailed implementation process and principle of the step 208 and the step 209 may refer to the detailed description of the above embodiments, and are not described herein again.

The method for managing the queues of the network card provided by the embodiment of the application determines the base address of the virtual network interface to be created in a preset queue mapping table according to the identifier of the virtual network interface to be created included in the virtual network interface creation request and the maximum queue number supported by each virtual network interface corresponding to the network card when the virtual network interface creation request corresponding to the network card is acquired and the number of the idle queues corresponding to the network card is greater than or equal to the number of the request queues, traverses the queue state array corresponding to the network card, determines the queue with the queue state in the idle state as the queue to be allocated according to the number of the request queues, then sequentially fills the identifier of each queue to be allocated into the preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table, and further according to the identifier of the queue to be allocated and the number of the queue to be allocated, and updating the queue state array and the number of free queues. Therefore, by presetting a queue mapping table in the network card and carrying out dynamic queue management through the queue mapping table, idle queues corresponding to the network card are flexibly distributed to each network interface, and queues are distributed to the network interfaces according to the number of request queues in the creation request, so that queue resources in the network card are fully utilized, the processing efficiency of the network card is improved, and the running reliability of the network card is further improved.

In a possible implementation form of the present application, the method for managing the queue of the network card according to the embodiment of the present application may further delete a created virtual network interface, and timely release queue resources in the network card, thereby further improving the utilization rate of the queue resources and improving the processing efficiency of the network card.

The queue management method of the network card provided in the embodiment of the present application is further described below with reference to fig. 7.

Fig. 7 is a flowchart illustrating a further method for managing a queue of a network card according to an embodiment of the present application.

As shown in fig. 7, the method for managing the queue of the network card includes the following steps:

step 301, obtaining a virtual network interface creation request corresponding to the network card, where the virtual network interface creation request includes an identifier of a virtual network interface to be created and a number of request queues corresponding to the virtual network interface to be created.

Step 302, when the number of idle queues corresponding to the network card is greater than 0, determining a base address of the virtual network interface to be created in a preset queue mapping table according to the identifier of the virtual network interface to be created and the maximum number of queues supported by each virtual network interface corresponding to the network card.

Step 303, traversing the queue state array corresponding to the network card, and determining the queue with the queue state being an idle state as the queue to be allocated in sequence until the traversal of the queue state array is completed, or until the number of the queues to be allocated is equal to the number of the request queues.

And step 304, sequentially filling the identifier of each queue to be allocated into a preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table.

Step 305, updating the queue state array and the number of idle queues according to the identifiers of the queues to be allocated and the number of the queues to be allocated.

The detailed implementation process and principle of the steps 301-305 can refer to the detailed description of the above embodiments, and are not described herein again.

Step 306, a virtual network interface deletion request corresponding to the network card is obtained, wherein the virtual network interface deletion request includes an identifier of the virtual network interface to be deleted.

The virtual network interface deletion request may be sent to the network card by an application program in the electronic device where the network card is located, so as to delete the corresponding relationship between the corresponding network interface and the queue from a preset queue mapping table according to actual needs.

In the embodiment of the application, the management software in the network card may obtain, in real time, a virtual network interface deletion request sent by an application program in the electronic device, and perform analysis processing on the virtual network interface deletion request to determine an identifier of a virtual network interface to be deleted included in the virtual network interface deletion request.

Step 307, traversing the queue state array to obtain a corresponding relationship between the identifier of each queue in the network card and the queue state and an association relationship between the identifier of each queue and the identifier of the virtual network interface.

In this embodiment, the queue state array corresponding to the network card may store the queue state of each queue in the network and the virtual network interface associated with each queue. Therefore, after the virtual network interface deletion request is obtained, the queue state array corresponding to the network card can be traversed to obtain the corresponding relation between the identifier of each queue in the network card and the queue state and the incidence relation between the identifier of each queue and the identifier of the virtual network interface, and further determine the queue allocated to the virtual network interface to be deleted in the network card.

Step 308, deleting the identifier of the current queue from the preset queue mapping table, updating the queue state corresponding to the current queue in the queue state array to be an idle state, and adding one to the number of the idle queues when the queue state corresponding to the current queue is the use state and the identifier of the current queue is associated with the identifier of the virtual network interface to be deleted.

In this embodiment of the application, when traversing the queue state array corresponding to the network card, if the queue state corresponding to the current queue is the use state and the identifier of the current queue is associated with the identifier of the virtual network interface to be deleted, it may be determined that the current queue is the queue allocated to the virtual network interface to be deleted, so that the identifier of the current queue may be deleted from the preset queue mapping table, and a preset value (for example, the preset value may be-1) is filled in the storage unit corresponding to the identifier of the current queue, and then the queue state corresponding to the current queue in the queue state array is updated to be the idle state, and the number of idle queues corresponding to the network card is increased by one, so as to update the number of the queue state array and the number of idle queues corresponding to the network card.

Step 309, when the queue status corresponding to the current queue is in an idle status, or the identifier of the current queue is not associated with the identifier of the virtual network interface to be deleted, skipping the current queue and obtaining the corresponding relationship between the identifier of the next queue in the queue status array and the queue status, and the associated relationship between the identifier of the next queue and the identifier of the virtual network interface, until the queue status array is completely traversed.

In this embodiment of the application, when traversing the queue state array corresponding to the network card, if the queue state corresponding to the current queue is an idle state, or the queue state of the current queue is a use state but is not associated with the identifier of the virtual network interface to be deleted, it may be determined that the current queue is not a queue allocated to the virtual network interface to be deleted, and the current queue may be skipped to continuously obtain the corresponding relationship between the identifier of the next queue in the queue state array and the queue state and the associated relationship between the identifier of the next queue and the identifier of the virtual network interface until the traversal of the queue state array is completed, and it may be determined that the virtual network interface is deleted.

According to the queue management method of the network card, when a virtual network interface deletion request corresponding to the network card is obtained, the queue state array is traversed, the identification of the current queue is deleted from the preset queue mapping table under the condition that the queue state corresponding to the current queue is a use state and the identification of the current queue is associated with the identification of the virtual network interface to be deleted, the queue state corresponding to the current queue in the queue state array is updated to be an idle state, the number of the idle queues is increased by one, and the next queue in the queue state array traversed by the current queue is skipped under the condition that the queue state corresponding to the current queue is an idle state or the identification of the current queue is not associated with the identification of the virtual network interface to be deleted, so that the virtual network interface is deleted. Therefore, by presetting a queue mapping table in the network card and carrying out dynamic queue management through the queue mapping table, the idle queue corresponding to the network card is flexibly distributed to each network interface, the created virtual network interface can be deleted, and the queue resources in the network card are released in time, so that the utilization rate of the queue resources is further improved, and the processing efficiency of the network card is improved.

In a possible implementation form of the present application, an application program in an electronic device where a network card is located may access an actual physical queue that needs to be used for sending a data packet through a preset queue mapping table, so as to ensure reliability of operation of the network card.

The queue management method of the network card provided in the embodiment of the present application is further described below with reference to fig. 8.

Fig. 8 is a flowchart illustrating a method for managing a queue of a network card according to an embodiment of the present application.

As shown in fig. 8, the method for managing the queue of the network card includes the following steps:

step 401, obtaining a virtual network interface creation request corresponding to the network card, where the virtual network interface creation request includes an identifier of a virtual network interface to be created and a number of request queues corresponding to the virtual network interface to be created.

Step 402, determining a base address of the virtual network interface to be created in a preset queue mapping table according to the identifier of the virtual network interface to be created and the maximum queue number supported by each virtual network interface corresponding to the network card under the condition that the number of idle queues corresponding to the network card is greater than 0.

Step 403, traversing the queue state array corresponding to the network card, and sequentially determining the queue with the queue state being an idle state as a queue to be allocated until the traversal of the queue state array is completed, or until the number of the queues to be allocated is equal to the number of the request queues.

Step 404, sequentially filling the identifier of each queue to be allocated into a preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table.

Step 405, updating the queue state array and the number of idle queues according to the identifier of the queue to be allocated and the number of the queue to be allocated.

The detailed implementation process and principle of the

steps

401 and 405 can refer to the detailed description of the above embodiments, and are not described herein again.

Step 406, a data packet sending request sent by the first application to the network card is obtained, where the data packet sending request includes a base address and an offset address corresponding to the first target queue in the preset queue mapping table.

The first application program refers to an upper application program which is required to send a data packet to other equipment currently in the electronic equipment where the network card is currently located.

The data packet sending request may be generated by a driver corresponding to the network interface and sent to the management software 3 in the network card when the first application needs to send a data packet to another device through the network link.

The first target queue refers to a queue in a network card that needs to be used when the first application program sends a data packet currently.

In this embodiment, the driver software of the network interface may calculate five tuple information (a protocol type, a source IP address, a destination IP address, a source port number, and a destination port number) of a to-be-sent data packet of the first application program through a hash algorithm, determine a first target queue that needs to be used by the first application program to send the to-be-sent data packet, generate a base address and an offset address corresponding to the first target queue in a preset queue mapping table, and send the base address and the offset address to the management software, so that the management software queries an identifier of the first target queue from the preset queue mapping table according to the base address and the offset address corresponding to the first target queue.

Step 407, acquiring the identifier of the first target queue from the preset queue mapping table according to the base address and the offset address corresponding to the first target queue.

In this embodiment of the present application, after the management software determines the base address and the offset address corresponding to the first target queue, the management software may obtain the identifier of the first target queue from the corresponding storage unit of the preset queue mapping table according to the base address and the offset address corresponding to the first target queue.

For example, as shown in fig. 5, assuming that the maximum number of queues supported by each virtual network interface is 64, the base address of NET0 is 0, and the base address of NET1 is 64, if the base address of the first target queue is 64 and the offset address is 2, the identifier of the first target queue may be determined to be 6.

Step 408, according to the identifier of the first target queue, obtaining a pointer and/or a storage address corresponding to the data packet to be sent from the first target queue.

In the embodiment of the application, after the identifier of the first target queue is determined, the first target queue can be accessed according to the identifier of the first target queue, information such as a pointer and a storage address corresponding to a data packet to be sent is obtained from the first target queue, and the data packet to be sent is read from a corresponding storage space according to the information such as the pointer and/or the storage address corresponding to the data packet to be sent.

Step 409, initiating a read operation to the first application program according to the pointer and/or the storage address corresponding to the data packet to be sent to acquire the data packet to be sent, and sending the data packet to be sent through the first virtual network interface corresponding to the first target queue.

In this embodiment of the application, after the information such as the pointer and/or the storage address corresponding to the data packet to be sent is obtained, a read operation may be initiated to the first application according to the pointer and/or the storage address corresponding to the data packet to be sent, so as to read information such as a descriptor and a buffer area of the data packet to be sent from a corresponding storage space, and send the data packet to be sent through the first virtual network interface corresponding to the first target queue, thereby completing a sending process of the data packet.

According to the queue management method for the network card, when a data packet sending request sent to the network card by a first application program is obtained, according to a base address and an offset address corresponding to a first target queue in a preset queue mapping table included in the data packet sending request, an identifier of the first target queue is obtained from the preset queue mapping table, according to the identifier of the first target queue, a pointer and/or a storage address corresponding to a data packet to be sent are obtained from the first target queue, then, a read operation is initiated to the first application program according to the pointer and/or the storage address corresponding to the data packet to be sent, so that the data packet to be sent is obtained, and the data packet to be sent is sent through a first virtual network interface corresponding to the first target queue. Therefore, by presetting a queue mapping table in the network card and carrying out dynamic queue management through the queue mapping table, idle queues corresponding to the network card are flexibly distributed to each network interface, and an application program in the electronic equipment where the network card is located can access actual physical queues required to be used for sending data packets through the preset queue mapping table, so that the utilization rate of queue resources and the processing efficiency of the network card are improved, and the running reliability of the network card is further improved.

In a possible implementation form of the present application, an application program in an electronic device where a network card is located may access an actual physical queue that needs to be used for receiving a data packet through a preset queue mapping table, so as to ensure reliability of operation of the network card.

The queue management method of the network card provided in the embodiment of the present application is further described below with reference to fig. 9.

Fig. 9 is a flowchart illustrating a method for managing a queue of another network card according to an embodiment of the present application.

As shown in fig. 9, the method for managing the queue of the network card includes the following steps:

step 501, acquiring a virtual network interface creation request corresponding to a network card, where the virtual network interface creation request includes an identifier of a virtual network interface to be created and a number of request queues corresponding to the virtual network interface to be created.

Step 502, determining a base address of the virtual network interface to be created in a preset queue mapping table according to the identifier of the virtual network interface to be created and the maximum queue number supported by each virtual network interface corresponding to the network card, when the number of idle queues corresponding to the network card is greater than 0.

Step 503, traversing the queue state array corresponding to the network card, and determining the queue with the queue state being an idle state as the queue to be allocated in sequence until the traversal of the queue state array is completed, or until the number of the queue to be allocated is equal to the number of the request queues.

Step 504, sequentially filling the identifier of each queue to be allocated into a preset queue mapping table according to the base address of the virtual network interface to be created in the preset queue mapping table.

And 505, updating the queue state array and the number of idle queues according to the identifier of the queue to be distributed and the number of the queue to be distributed.

The detailed implementation process and principle of the steps 501-505 may refer to the detailed description of the embodiments, and are not described herein again.

Step 506, a data packet to be received by the physical network interface of the network card is obtained.

The data packet to be received refers to a data packet sent by other equipment, which is received by a physical network interface of the network card through a network link.

In this embodiment, the network card may include a physical network interface and a virtual network interface, and when receiving a data packet sent by another device through a network, the network card may receive the data packet to be received through the physical network interface, and further determine the virtual network interface and the queue for receiving the data packet to be received according to the received data packet to be received.

Step 507, the data packet to be received is analyzed to determine the identifier of the second virtual network interface corresponding to the data packet to be received, and the base address and the offset address corresponding to the second target queue in the preset queue mapping table.

The second virtual network interface is a network interface to be simulated, which is required to be used by the network card to currently receive the data packet to be received.

The second target queue refers to a queue that needs to be used by the network card to currently receive the data packet to be received. It should be noted that the second target queue is a queue allocated to the second virtual network interface.

In this embodiment, after receiving a data packet to be received, a network card may utilize an OVS module in the network card to perform parsing on the data packet to be received, so as to determine a virtual network interface for receiving the data packet to be received, further calculate, according to a hash algorithm, quintuple information corresponding to the data packet to be received through driver software corresponding to the network interface, so as to determine a second target queue that needs to be used for receiving the data packet to be received, generate a base address and an offset address corresponding to the second target queue in a preset queue mapping table, and send the base address and the offset address to management software, so that the management software queries an identifier of the second target queue from the preset queue mapping table according to the base address and the offset address corresponding to the second target queue.

And step 508, acquiring the identifier of the second target queue from the preset queue mapping table according to the base address and the offset address corresponding to the second target queue.

In the embodiment of the present application, after the management software determines the base address and the offset address corresponding to the second target queue, the identifier of the second target queue may be obtained from the corresponding storage unit of the preset queue mapping table according to the base address and the offset address corresponding to the second target queue.

For example, as shown in fig. 5, assuming that the maximum number of queues supported by each virtual network interface is 64, the base address of NET0 is 0, and the base address of NET1 is 64, if the base address of the first target queue is 0 and the offset address is 1, it may be determined that the identifier of the second target queue is 2.

Step 509, according to the identifier of the second target queue, obtaining a pointer and/or a storage address corresponding to the data packet to be received from the second target queue.

In the embodiment of the present application, after the identifier of the second target queue is determined, the second target queue may be accessed according to the identifier of the second target queue, and information such as a pointer and a storage address corresponding to the data packet to be received is obtained from the second target queue, so that the data packet to be received is written into a corresponding storage space according to the information such as the pointer and/or the storage address corresponding to the data packet to be received.

Step 510, writing the data packet to be received into the memory according to the pointer and/or the storage address corresponding to the data packet to be received, and sending the data to be received to the second application program through the second virtual network interface corresponding to the second target queue.

The second application program is an upper layer application program that finally receives the data packet to be received.

In this embodiment of the application, after information such as a pointer and/or a storage address corresponding to a data packet to be received is obtained, a write operation may be initiated to a system memory according to the pointer and/or the storage address corresponding to the data packet to be received, so as to write the data packet to be received into a corresponding storage space, and the data packet to be received is sent to a second application program through a second virtual network interface corresponding to a second target queue, thereby completing a receiving process of the data packet.

In the method for managing the network card queue provided in the embodiment of the application, when the data packet to be received by the physical network interface of the network card is acquired, analyzing the data packet to be received to determine the identifier of the second virtual network interface corresponding to the data packet to be received, and the base address and the offset address corresponding to the second target queue in the preset queue mapping table, acquiring the identifier of a second target queue from a preset queue mapping table according to the base address and the offset address corresponding to the second target queue, then acquiring a pointer and/or a storage address corresponding to a data packet to be received from the second target queue according to the identifier of the second target queue, further writing the data packet to be received into the memory according to the pointer and/or the memory address corresponding to the data packet to be received, and sending the data to be received to a second application program through a second virtual network interface corresponding to the second target queue. Therefore, by presetting a queue mapping table in the network card and carrying out dynamic queue management through the queue mapping table, the idle queues corresponding to the network card are flexibly distributed to each network interface, and an application program in the electronic equipment where the network card is located can access the actual physical queues required to be used for receiving the data packets through the preset queue mapping table, so that the utilization rate of queue resources and the processing efficiency of the network card are improved, and the running reliability of the network card is further improved.
