The above will be discussed in detail below. Please refer to fig. 2. Fig. 2 is a flowchart of another message distribution method according to an embodiment of the present invention. The message distribution method comprises the following steps:
201. in the process of initializing the multi-core processor or in the process of operating the multi-core processor, establishing a first corresponding relationship between an application program APP and a service core so that a distribution unit in the multi-core processor distributes a message according to the first corresponding relationship, wherein the first corresponding relationship comprises a first sub-corresponding relationship, the first sub-corresponding relationship is a corresponding relationship between a first APP and a first service core, and the first service core is the service core in the multi-core processor.
In an embodiment of the invention, after execution 201, 202, or 203, or 204 may be executed.
In the embodiment of the present invention, in an initialization process of a multi-core processor or in an operation process of the multi-core processor, a first corresponding relationship between an APP and a service core is established, so that a distribution unit in the multi-core processor distributes a packet according to the first corresponding relationship, where the first corresponding relationship includes a first sub-corresponding relationship, the first sub-corresponding relationship is a corresponding relationship between the first APP and a first service core, and the first service core is a service core in the multi-core processor.

In particular implementation, the execution subject of 201 may be a control core.
It should be noted that, in the embodiment of the present invention, when the distribution unit is implemented specifically, the distribution unit may be a hardware module in a multi-core processor. In addition, the distribution unit may also be implemented by software.
In the embodiment of the present invention, the first sub-mapping relationship is a mapping relationship between the first APP and the first service core. In particular, the first APP refers to a certain APP. Hereinafter, the APP will be described, and will not be described in detail here. The first service core may be one service core or a plurality of service cores.
The first sub-correspondence is used for message distribution. In specific implementation, after receiving a message, a distribution unit determines the type of the APP corresponding to the message. If the APP corresponding to the message is the first APP, the distribution unit distributes the message to the first service core according to the first sub-correspondence. In a scenario where the first service core is a plurality of service cores, the distribution unit may distribute the packet to one of the plurality of service cores according to a predetermined rule.
In a specific implementation, the first corresponding relationship may include other sub-corresponding relationships in addition to the first sub-corresponding relationship. For example, the first corresponding relationship may further include an eighth sub-corresponding relationship, where the eighth sub-corresponding relationship is a corresponding relationship between an eighth APP and an eighth service core, and the eighth service core is a service core in the multi-core processor. The eighth sub-correspondence is similar to the first sub-correspondence, and is not described herein again. It is noted that the eighth APP is different from the first APP and the second APP.
In the embodiment of the present invention, APP refers to an Application Program (APP). For example, APP may be a network stream (netstream). The network flow is a statistical technique based on network traffic information. The APP may also be Bidirectional Forwarding Detection (BFD).
202. And in the operation process of the multi-core processor, adding a second sub-corresponding relationship in the first corresponding relationship, wherein the second sub-corresponding relationship is a corresponding relationship between a second APP and a second service core, and the second service core is a service core in the multi-core processor.
When the second sub-correspondence is added to the first correspondence, the specific implementation may be:
the user enables the second APP by means of a command line. The control core senses that the second APP is enabled, and the second sub-corresponding relation is added to the first corresponding relation.
And in the operation process of the multi-core processor, the control core adds a second sub-corresponding relation in the first corresponding relation, the second sub-corresponding relation is the corresponding relation between a second APP and a second service core, and the second service core is a service core in the multi-core processor.
In this embodiment of the present invention, when the control core adds the second sub-correspondence to the first correspondence, the specific implementation may be:
the control core determines available ones of the service cores of the multi-core processor. The available service cores have a specific meaning. The "available" of the available service cores emphasizes that the service core has additional processing power. The available service cores include service cores which have not established a corresponding relationship with the APP, and also include service cores which have established a corresponding relationship with the APP, but have additional processing capacity. The processing capability of the service core is influenced by the operating frequency of the service core, the manufacturing process and other factors. The processing power of the business core can be obtained by prototype testing.
The control core determines a second service core allocated to a second APP from the available service cores. And the control core adds a second sub-corresponding relation formed by a second APP and a second service core in the first corresponding relation. For example, the multi-core processor includes 5 service cores having the same processing capability, i.e., service cores 1 to 5. Wherein the service core 4 and the service core 5 have no additional processing capacity. The business core 1 and the business core 3 do not establish a corresponding relationship with the APP. The service core 2 has an additional processing capacity, which is equal to the processing capacity of 0.5 service cores for the service core 2. Thus, available service cores include: a service core 1, a service core 2 and a service core 3. If the second APP requires 2.5 service cores, the service core 1, the service core 2, and the service core 3 may be allocated to the second APP. That is, the second service core includes service cores 1 to 3.
It should be noted that, the control core may determine the number of service cores that need to be allocated to the second APP according to the stored service specification parameter of the second APP. The specific implementation can be as follows:
the license document describes the service specification of the second APP. The service specification may be the number of sessions of the second APP, for example, 1000 sessions, or the service specification may be a detection period, for example, the detection period of the second APP is 10 ms. In addition, the control core can access the corresponding relation between the pre-stored service specification of the APP to be processed and the number of the required service cores. The corresponding relation between the business specification of the APP to be processed and the number of the needed business cores can be obtained through prototype testing. The control core may determine the service specification of the second APP through the license file of the second APP. The control core may determine the number of service cores to be allocated by the second APP according to the correspondence between the service specification of the APP to be processed and the number of service cores required.
It should be noted that the number of the service cores to be allocated by the second APP may be an integer or a decimal number.
In the embodiment of the present invention, the control core may add the second sub-correspondence to the first correspondence, so that the distribution unit can distribute the packet according to the second correspondence, thereby improving the flexibility of the core resource allocation manner.
203. And deleting the first sub-corresponding relation in the first corresponding relation in the running process of the multi-core processor.
In the operating process of the multi-core processor, the control core may delete the first sub-correspondence in the first correspondence, that is, delete the first sub-correspondence of the first APP and the first service core in the first correspondence.
The specific implementation of deleting the first sub-correspondence relationship may be:
the user disables the second APP by means of a command line. And the control core senses that the second APP is forbidden and deletes the first sub-corresponding relation.
204. And in the operation process of the multi-core processor, modifying the first sub-corresponding relationship into a third sub-corresponding relationship, wherein the third sub-corresponding relationship is the corresponding relationship between the first APP and a third service core, and the third service core is a service core in the multi-core processor.
And in the operation process of the multi-core processor, the control core modifies the first sub-corresponding relation into a third sub-corresponding relation, the third sub-corresponding relation is the corresponding relation between the first APP and the third service core, and the third service core is a service core in the multi-core processor.
In the embodiment of the present invention, the modification of the first sub-correspondence to the third sub-correspondence may specifically be:
and the control core determines the available service cores in the service cores of the multi-core processor and modifies the first sub-corresponding relation into a third sub-corresponding relation. And the third sub-corresponding relationship is a corresponding relationship between the first APP and the third service core. The third service core comprises a first service core and a fourth service core. The fourth service core is an available service core. The above means that the number of the service cores corresponding to the first APP is increased by modifying the first sub-correspondence relationship into the third sub-correspondence relationship.
For example, the first service core corresponding to the first APP in the first sub-correspondence relationship includes a service core 1 and a service core 2. And the service specification in the license file corresponding to the first APP is modified into a new service specification. The number of the service cores corresponding to the new service specification is 3. The control core senses that the service specification in the license file corresponding to the first APP changes, and determines an available service core, namely a service core 3, from the service cores of the multi-core processor. The service core 3 is a fourth service core. And the control core modifies the first sub-corresponding relation into a third sub-corresponding relation. In the third sub-correspondence relationship, the third service core includes a service core 1, a service core 2, and a service core 3.
In this embodiment of the present invention, modifying the first sub-correspondence to the third sub-correspondence may further be:
the control core determines available ones of the service cores of the multi-core processor. And modifying the first sub-corresponding relationship into a third sub-corresponding relationship, wherein the third sub-corresponding relationship is the corresponding relationship between the first APP and the third service core. The first service core comprises a third service core and a fifth service core, and the fifth service core is a service core in the multi-core processor. The above means that the number of the service cores corresponding to the first APP is reduced by modifying the first sub-correspondence relationship into the third sub-correspondence relationship.
For example: in the first sub-correspondence relationship, the first service core includes a service core 1, a service core 2, and a service core 3. And the service specification in the license file corresponding to the first APP is modified into a new service specification. The number of the service cores corresponding to the new service specification is 2. The control core senses that the service specification in the license file corresponding to the first APP changes, and determines the service core 3 as a fifth service core. In the third sub-correspondence relationship, the third service core includes a service core 1 and a service core 2. The third sub-correspondence does not include the service core 3. Meaning that the service core 3 becomes an available service core, and the service core 3 can be used when a sub-correspondence is subsequently established or a correspondence is modified.
It should be noted that, in the embodiment of the present invention, the first corresponding relationship, the first sub corresponding relationship, the second sub corresponding relationship, and the third sub corresponding relationship may be embodied in a corresponding table, or may be embodied in a computer program code. The present invention is not limited to a specific load bearing manner.
It can be determined from the above description of 204 that 204 can be applied in a scenario where the service specification of the first APP changes. That is to say, when the number of the service cores to be allocated by the first APP changes, the number of the service cores corresponding to the first APP is increased or decreased by modifying the correspondence between the first APP and the first service core.
In an embodiment, the distributing unit determines, for the received packet, a service core to process according to a corresponding relationship between the APP in the control core and the service core, and specifically may be:
the multi-core processor receives the message. And the message unit analyzes the message and determines the APP corresponding to the message. And the distribution unit searches the business core corresponding to the APP corresponding to the message in the corresponding relation between the APP and the business core according to the APP corresponding to the message. And the distribution unit distributes the received message to the searched service core.
It should be noted that "first" and "second" in the first corresponding relationship and the second corresponding relationship related to the embodiment of the present invention are used to distinguish different corresponding relationships, and are not used to define a sequence. Similarly, "first", "second", "third", and "eighth" in the first sub-correspondence, the second sub-correspondence, the third sub-correspondence, and the eighth sub-correspondence are used to distinguish different correspondences, and are not used to limit the order of precedence. The first, second, third, fourth, fifth and eighth service cores in the first, second, third, fourth, fifth and eighth service cores are used for distinguishing different service cores, and are not used for limiting the order.
In addition, the first service core, the second service core, the third service core, the fourth service core, the fifth service core and the eighth service core all refer to a set of service cores, and the set may include one service core or a plurality of service cores.
It should be noted that, in the embodiment of the present invention, the second embodiment is a refinement and supplement of the first embodiment. The contents of the first and second embodiments may be combined.
In the embodiment of the present invention, after the first corresponding relationship is established, the flexibility of the service core resource allocation manner can be improved by modifying the first corresponding relationship, specifically including adding the second sub-corresponding relationship to the first corresponding relationship, or deleting the first sub-corresponding relationship in the first corresponding relationship, or modifying the first sub-corresponding relationship.

The modifying unit 302 in the third embodiment may be configured to modify the first corresponding relationship into the second corresponding relationship, where the modifying is to add a second sub-corresponding relationship in the first corresponding relationship, or to delete a first sub-corresponding relationship in the first corresponding relationship, or to modify the first sub-corresponding relationship. The above will be discussed in detail below. Please refer to fig. 4. Fig. 4 is a schematic structural diagram of another message distribution apparatus according to an embodiment of the present invention.
Referring to fig. 4, when the modification unit 302 is implemented specifically, it may be an add subunit 401, a delete subunit 402, or a modify subunit 403. The detailed discussion is as follows:
the adding subunit 401 is configured to add a second sub-correspondence relationship in the first correspondence relationship, where the second sub-correspondence relationship is a correspondence relationship between a second APP and a second service core, and the second service core is a service core in the multi-core processor.
When the second sub-correspondence is added to the first correspondence, the specific implementation may be:
the user enables the second APP by means of a command line. The control core senses that the second APP is enabled, and the second sub-corresponding relation is added to the first corresponding relation.
And in the operation process of the multi-core processor, the control core adds a second sub-corresponding relation in the first corresponding relation, the second sub-corresponding relation is the corresponding relation between a second APP and a second service core, and the second service core is a service core in the multi-core processor.
Optionally, the adding subunit 401 may include a first determining unit 501, a second determining unit 502, and a first adding unit 503. Please refer to fig. 5. Fig. 5 is a schematic structural diagram of an add-on subunit 401 in the embodiment of the present invention. The adding subunit 401 includes:
a first determining unit 501, configured to determine available service cores in the service cores of the multi-core processor.
The available service cores have a specific meaning. The "available" of the available service cores emphasizes that the service core has additional processing power. The available service cores include service cores which have not established a corresponding relationship with the APP, and also include service cores which have established a corresponding relationship with the APP, but have additional processing capacity. The processing capability of the service core is influenced by the operating frequency of the service core, the manufacturing process and other factors. The processing power of the business core can be obtained by prototype testing.
A second determining unit 502, configured to determine, after the first determining unit 501 determines the available service cores, the second service core allocated to the second APP from the available service cores.
A first adding unit 503, configured to add, in the first correspondence, a second sub-correspondence formed by the second APP and the second service core after the second determining unit determines the second service core.
For example, the multi-core processor includes 5 service cores having the same processing capability, i.e., service cores 1 to 5. Wherein the service core 4 and the service core 5 have no additional processing capacity. The business core 1 and the business core 3 do not establish a corresponding relationship with the APP. The service core 2 has an additional processing capacity, which is equal to the processing capacity of 0.5 service cores for the service core 2. Thus, available service cores include: a service core 1, a service core 2 and a service core 3. If the second APP requires 2.5 service cores, the service core 1, the service core 2, and the service core 3 may be allocated to the second APP. That is, the second service core includes service cores 1 to 3.
It should be noted that, the control core may determine the number of service cores that need to be allocated to the second APP according to the stored service specification parameter of the second APP. The specific implementation can be as follows:
the license document describes the service specification of the second APP. The service specification may be the number of sessions of the second APP, for example, 1000 sessions, or the service specification may be a detection period, for example, the detection period of the second APP is 10 ms. In addition, the control plane pre-stores the corresponding relation between the service specification of the APP to be processed and the number of the required service cores. The corresponding relation between the business specification of the APP to be processed and the number of the needed business cores can be obtained through prototype testing. The control core may determine the service specification of the second APP through the license file of the second APP. The control core may determine the number of service cores to be allocated by the second APP according to the correspondence between the service specification of the APP to be processed and the number of service cores required.
It should be noted that the number of the service cores to be allocated by the second APP may be an integer or a decimal number.
In the embodiment of the present invention, the control core may add the second sub-correspondence to the first correspondence, so that the distribution unit can distribute the packet according to the second correspondence, thereby improving the flexibility of the core resource allocation manner.
A deleting subunit 402, configured to delete the first sub-correspondence in the first correspondence.
In the operating process of the multi-core processor, the control core may delete the first sub-correspondence in the first correspondence, that is, delete the first sub-correspondence of the first APP and the first service core in the first correspondence.
The specific implementation of deleting the first sub-correspondence relationship may be:
the user disables the second APP by means of a command line. And the control core senses that the second APP is forbidden and deletes the first sub-corresponding relation.
The modifying subunit 403 is configured to modify the first sub-correspondence relationship into a third sub-correspondence relationship, where the third sub-correspondence relationship is a correspondence relationship between the first APP and a third service core, and the third service core is a service core in the multi-core processor.
And in the operation process of the multi-core processor, the control core modifies the first sub-corresponding relation into a third sub-corresponding relation, the third sub-corresponding relation is the corresponding relation between the first APP and the third service core, and the third service core is a service core in the multi-core processor.
Alternatively to this, the first and second parts may,
the modification subunit 403 may specifically include a third determining unit 601 and a first modifying unit 602. Please refer to fig. 6. Fig. 6 is a schematic structural diagram of the modifying subunit 403 in the embodiment of the present invention. The modification subunit 403 specifically includes:
a third determining unit 601, configured to determine available service cores in the service cores of the multi-core processor.
A first modifying unit 602, configured to modify the first sub-correspondence to the third sub-correspondence after the third determining unit determines the available service core, where the third sub-correspondence is a correspondence between the first APP and the third service core, the third service core includes the first service core and a fourth service core, and the fourth service core is the available service core.
The above means that the number of the service cores corresponding to the first APP is increased by modifying the first sub-correspondence relationship into the third sub-correspondence relationship.
For example, the first service core corresponding to the first APP in the first sub-correspondence relationship includes a service core 1 and a service core 2. And the service specification in the license file corresponding to the first APP is modified into a new service specification. The number of the service cores corresponding to the new service specification is 3. The control core senses that the service specification in the license file corresponding to the first APP changes, and determines an available service core, namely a service core 3, from the service cores of the multi-core processor. The service core 3 is a fourth service core. And the control core modifies the first sub-corresponding relation into a third sub-corresponding relation. In the third sub-correspondence relationship, the third service core includes a service core 1, a service core 2, and a service core 3.
Optionally, the modification subunit 403 may specifically include a third determining unit 601 and a second modifying unit 603. Referring to fig. 7, fig. 7 is a schematic diagram illustrating another structure of the modifying subunit 403 according to an embodiment of the present invention. The modification subunit 403 includes:
a third determining unit 601, configured to determine available service cores in the service cores of the multi-core processor.
A second modifying unit 603, configured to modify the first sub-correspondence to a third sub-correspondence after the third determining unit determines an available service core, where the third sub-correspondence is a correspondence between the first APP and the third service core, the first service core includes the third service core and a fifth service core, and the fifth service core is a service core in the multi-core processor.
The above means that the number of the service cores corresponding to the first APP is reduced by modifying the first sub-correspondence relationship into the third sub-correspondence relationship.
For example: in the first sub-correspondence relationship, the first service core includes a service core 1, a service core 2, and a service core 3. And the service specification in the license file corresponding to the first APP is modified into a new service specification. The number of the service cores corresponding to the new service specification is 2. The control core senses that the service specification in the license file corresponding to the first APP changes, and determines the service core 3 as a fifth service core. In the third sub-correspondence relationship, the third service core includes a service core 1 and a service core 2. The third sub-correspondence does not include the service core 3. Meaning that the service core 3 becomes an available service core, and the service core 3 can be used when a sub-correspondence is subsequently established or a correspondence is modified.

And the distribution unit searches the business core corresponding to the APP corresponding to the message in the corresponding relation between the APP and the business core according to the APP corresponding to the message. And the distribution unit distributes the received message to the searched service core.
