[0069] In order to make the technical personnel in the art better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0070] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in other than the order illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0071] In order to facilitate understanding, the professional terms that may be involved in the embodiments of the present application are first explained.

[0072] XLP processor, a multi-core MIPS processor, is mainly used for processing network traffic. XLP is a SOC (System on Chip) chip, which has 16 physical cores (i.e. microcore), each physical core including 4 logical cores, i.e. the XLP processor has 64 logical cores. The frequency of each core is 800Mhz-1.8GHz. The throughput of processing 64-byte packets can reach 100Gbps.

[0073] The default packet receiving processing mode of the existing XLP processor is to poll the 64 logical cores after receiving the packet, which cannot realize the packet distribution processing and the special core processing. In addition, the micro processing core corresponding to the packet receiving path is shared by the allocation mechanism of all physical channels, which causes the load of a certain physical channel to be too large to affect the packet receiving performance of other channels, and further causes the flow control and other problems.

[0074] To solve the above problems, the embodiment of the present application provides a packet processing method, device, network processor, electronic equipment and medium.

[0075] Figure 1 A flow chart of a packet processing method is provided for the embodiment of the present application, which can be applicable to the case of processing network packets. The method can be executed by a packet processing device, which can be realized in the form of hardware and / or software, and can be configured in a network processor. For example, the network processor can be an XLP (eXtreme Low Power) processor and the like. As shown in the figure, the method comprises the following steps. Figure 1

[0076] S110, obtaining a target packet to be processed.

[0077] The target packet can be a network packet received by the network processor and needing to be processed. For example, the target packet includes management packets and service packets and the like. In the embodiment of the present application, different logical cores are used to process the above-mentioned management packets and service packets. For example, part of the logical cores in the network processor are pre-configured to be used for processing the management packets, and the remaining logical cores are pre-configured to be used for processing the service packets, so as to realize the distribution processing of the management packets and the service packets. Taking the XLP processor as an example, the 64 logical cores are divided into two groups, the first 4 logical cores are a group and are used for processing the management packets, and the last 60 logical cores are a group and are used for processing the service packets.

[0078] Exemplarily, the target packet to be processed is obtained through the micro processing core corresponding to the packet processing channel, wherein the packet processing channel includes a service channel and a management channel, the service channel is a physical channel for transmitting and receiving service packets, the management channel is a physical channel for transmitting and receiving management packets, the micro processing core is a packet processing resource allocated to the physical channel, and the packet processing resources on each physical channel are independent of each other.

[0079] ​The message processing channel can be a physical channel in the network processor for transmitting and receiving messages. The physical channel can be a channel formed by various interfaces in the network processor. For example, the message processing channel can include a service channel and a management channel. The physical channels in the network processor can be configured to process only service messages and only management messages, respectively. The message processing resources are allocated to different physical channels, so that the management channel and the service channel are physically independent, and the micro processing cores corresponding to the physical channels are also independent.

[0080] The message processing resource can be a resource allocated to the message processing channel. For example, the message processing resource can be a buffer resource, etc. The main buffer resource can include a first-in first-out (FIFO) resource, a receive buffer (rx buffer) resource, a last-in first-out (LIFO) resource, and a micro processing core (i.e., a physical core), etc.

[0081] In the embodiment of the present application, the network processor uses the management channel to transmit and receive management messages, and uses a polling method to determine idle micro processing cores corresponding to the management channel, and distributes the management messages to the idle micro processing cores for processing. In addition, the network processor uses the service channel to transmit and receive service messages, and uses a polling method to determine idle micro processing cores corresponding to the service channel, and distributes the service messages to the idle micro processing cores for processing. This design realizes the separate processing of service messages and management messages.

[0082] In some embodiments, an XLP processor is taken as an example, one micro processing core is allocated to the management channel, and all management messages of the management channel pass through the micro processing core to determine the logical core. The remaining 15 micro processing cores are all allocated to the service channel, and all service messages of the service channel are processed by the 15 micro processing cores in a polling manner. The resource utilization rate of each micro processing core can be polled, and whether the micro processing core is in an idle state is determined according to the resource utilization rate. The micro processing core in the idle state is used to distribute the service messages. For example, if the resource utilization rate of a micro processing core is less than a set threshold, it is determined that the micro processing core is in the idle state. If there are multiple micro processing cores with resource utilization rates less than the set threshold, the micro processing core with the smallest resource utilization rate is used to distribute the service messages.

[0083] Figure 2 A resource allocation diagram is provided for the embodiment of the present application. As shown in FIG. 1, the network processor includes a management channel and a service channel. The management channel is allocated a micro processing core, and the service channel is allocated 15 micro processing cores. The management channel and the service channel are physically independent, and the micro processing cores corresponding to the management channel and the service channel are also independent. Figure 2As shown, the service channel and the management channel involved in the packet receiving path 21 each have independent FIFO resource 22, rx buffer resource 23, LIFO resource 24 and micro-processing core 25, instead of all the physical channels sharing the above resources, realizing channel separation and the effect of independent message processing resources among the physical channels, avoiding the performance problem of a certain physical channel affecting other physical channels, and enhancing the robustness of the system.

[0084] It should be noted that there are many ways to allocate message processing resources on different physical channels, and the embodiments of the present application do not make specific limitations. For example, the message processing resources can be allocated to the management channel and the service channel in proportion according to the number of management channels and service channels in the physical channel. Or, according to the number of management messages and service messages in a period of time, the weights of the management channel and the service channel are determined, and the message processing resources are allocated to the management channel and the service channel according to the weights.

[0085] S120, determining a logical core identifier according to the characteristic information of the target message.

[0086] The target field can be a characteristic field representing a basic hash value of the service message, and the logical core identifier is determined by the basic hash value, which can be determined based on the processing result of the previous processing unit of the service message, and can be a basic hash value. The position of the target field in the service message is related to the message type, and the position of the target field is different in different types of service messages, and the content of the target field is also different.

[0087] The logical core identifier is used to represent the logical core for processing the target message. Since the network processor is pre-configured with micro-processing cores dedicated to processing service messages and micro-processing cores dedicated to processing management messages, and each micro-processing core corresponds to multiple logical processing cores, i.e. pre-configured with logical processing cores dedicated to processing service messages as a first logical core group. The logical core identifier is used to distinguish different logical cores in the first logical core group. In addition, the logical processing cores dedicated to processing management messages are pre-configured as a second logical core group. The logical core identifier is used to distinguish different logical cores in the second logical core group.

[0088] Exemplarily, the determining of the logical core identifier according to the characteristic information of the target message comprises: in the case that the target message is a service message, parsing the service message through the micro-processing core corresponding to the service channel to obtain a message type field; obtaining a target field of the service message according to the message type field; and determining the logical core identifier corresponding to the service message according to the target field and the number of logical cores in the first logical core group, wherein the target logical core group includes the first logical core group, and the first logical core group includes logical cores for processing service messages.

[0089] The message type field can be a characteristic field representing the type of the service message. For example, the message type field in the fragmentation message is "FP". When the message type field is "FP" is obtained by analyzing the service message, it is determined that the service message is a fragmentation message.

[0090] Since the network processor pre-allocates different micro-processing cores for the service channel and the management channel, there is an association between the channel identifier and the micro-processing core identifier. The target message carries the channel identifier. After the network processor obtains the target message, if it is determined that the target message is a service message according to the channel identifier, the micro-processing cores pre-allocated for the service channel are polled to determine an idle micro-processing core to analyze and process the service message, and the message type field of the service message is obtained.

[0091] The message type field is used to determine the field position of the basic hash value in the service message. The basic hash value in the service message is obtained from the field position. The hash value is calculated again by using the set hash algorithm according to the basic hash value and the number of logical cores in the first logical core group, and the logical core identifier is obtained. The logical core identifier obtained by the calculation is the identifier information of the logical core processing the service message.

[0092] S130, determining a target logical core from the target logical core group according to the logical core identifier, and distributing the target message to the target logical core for processing.

[0093] For example, since the logical core identifier is used to distinguish the logical cores in the target logical core group, the target logical core can be selected from the target logical core group based on the logical core identifier, and the target message can be distributed to the target logical core for processing, so that the target message is processed by the specified logical core.

[0094] For example, the first logical core can be selected from the first logical core group based on the logical core identifier when the target message is a service message, and the service message can be distributed to the first logical core for processing, so that the service message is processed by the specified logical core.

[0095] The embodiments of the present disclosure provide a message processing method. The logical core identifier is determined based on the characteristic information of the target message, and the target message is distributed to the specified logical core for processing according to the logical core identifier. According to the embodiments of the present disclosure, the network message is distributed to the specified logical core for processing according to the message characteristics, the message processing efficiency is improved, and the resource waste is reduced.

[0096] Figure 3A flowchart of another packet processing method provided by an embodiment of the present application is shown in FIG. 10. The embodiment is based on the above-mentioned embodiment, and further limits that the target field of the service packet is acquired according to the packet type field; and the logical core identifier corresponding to the service packet is determined according to the target field and the number of logical cores in the first logical core group. As shown in FIG. 10, the method comprises the following steps. Figure 3

[0097] S310, acquiring a target packet to be processed.

[0098] S320, in the case that the target packet is a service packet, parsing the service packet by a micro-processing core corresponding to the service channel to obtain a packet type field.

[0099] S330, determining position information of the target field in the service packet according to the packet type field.

[0100] The position information can be the field position of the target field in the service packet. The target field can be a characteristic field representing a basic hash value of the service packet. The definition of the target field has been described in the above-mentioned embodiment, and will not be repeated here.

[0101] Exemplarily, the position information of the target field in the service packet is determined according to the packet type field according to the association relationship between the packet type and the position information of the target field.

[0102] S340, acquiring the target field in the service packet according to the position information.

[0103] Exemplarily, the target field is acquired from the service packet based on the position information. The target field can be a basic hash value output by a previous processing unit, or the target field can be a basic hash value determined based on the result output by the previous processing unit, etc. After the service packet is processed by the previous processing unit, the service packet carries the basic hash value, and the position of the characteristic field corresponding to the basic hash value in the service packet is different for different types of service packets.

[0104] S350, determining the logical core identifier corresponding to the service packet according to the target field, the service channel identifier, the number of distributed service packets, and the number of logical cores in the first logical core group.

[0105] The service channel identifier can be the identifier information of the physical channel used for processing the service packet. The number of distributed service packets can be the number of service packets distributed by the micro-processing core, which can be recorded by a counter in the micro-processing core. For example, the micro-processing core can increase the count value of the counter by 1 after distributing a service packet to a designated logical core each time.

[0106] ​Exemplarily, after the micro-processing core acquires the target field in the service packet according to the position information, a set hash algorithm in the micro-processing core code is used to calculate a hash value of the target field, the service channel identifier, and the number of distributed packets to the number of logical cores in the first logical core group, and the hash value is the logical core identifier corresponding to the service packet. The number of distributed packets refers to the number of service packets distributed by the current micro-processing core, which is determined by polling the micro-processing cores corresponding to the service channel.

[0107] Specifically, the micro-processing core can splice the basic hash value, the service channel identifier, and the number of distributed packets of the micro-processing core to obtain a spliced value, calculate a hash value of the spliced value to the number of logical cores in the first logical core group, and distribute the service packet to the specified logical core for processing according to the hash value.

[0108] Alternatively, the micro-processing core can perform mathematical operations based on the basic hash value, the service channel identifier, and the number of distributed packets of the micro-processing core to obtain an operation result, calculate a hash value of the operation result to the number of logical cores in the first logical core group, and distribute the service packet to the specified logical core for processing according to the hash value.

[0109] S360, determining a target logical core from the target logical core group according to the logical core identifier, and distributing the target packet to the target logical core for processing.

[0110] The embodiment of the present disclosure provides another packet processing method. The packet type field is obtained by analyzing the service packet, the position of the basic hash value in the service packet is determined based on the packet type field, the basic hash value is obtained from the service packet, and then the logical core identifier is determined based on the basic hash value, the service channel identifier, and the number of distributed packets, so as to distribute the service packet to the specified logical core, thereby improving the packet processing efficiency. Since the step of distributing the network packet to the logical core for processing by using the polling method is omitted, the resource waste is reduced.

[0111] Figure 4 A flowchart of another packet processing method provided by the embodiment of the present disclosure is provided. The embodiment of the present disclosure adds a processing flow of a management packet to the above-mentioned embodiment. As shown in the figure, Figure 4 the method comprises:

[0112] S410, obtaining a target packet to be processed by a micro-processing core corresponding to a packet processing channel, and in the case that the target packet is a service packet, continuing to perform S420, and in the case that the target packet is a management packet, continuing to perform S470.

[0113] Exemplarily, the management message is acquired through at least one management channel, and the service message is acquired through at least one service channel, wherein the management channel and the service channel are independent physical channels, and the message processing resources allocated to the management channel and the service channel are also independent, that is, each management channel or service channel occupies independent message processing resources, which mainly include FIFO resources, rx buffer resources, LIFO resources, micro-processing cores and the like.

[0114] Taking the XLP processor as an example, one of the 16 micro-processing cores is allocated to the management channel, and the management messages of all the management channels are distributed through the micro-processing core, and the remaining 15 micro-processing cores are allocated to the service channel, and the service messages of all the service channels are processed by the 15 micro-processing cores in turn. Since one micro-processing core corresponds to four logical cores, the four logical cores corresponding to the micro-processing core allocated to the management channel are taken as a second logical core group and are used for processing the management messages. The 60 logical cores corresponding to the 15 micro-processing cores allocated to the service channel are taken as a first logical core group and are used for processing the service messages.

[0115] S420, the message type field is obtained by parsing the service message through the micro-processing core corresponding to the service channel.

[0116] In some embodiments, for the service message, the micro-processing core corresponding to the service channel is polled to determine the micro-processing core used for processing the service message, and after the micro-processing core acquires the service message, the message type field is obtained by parsing the service message.

[0117] S430, the position information of the target field in the service message is determined according to the message type field.

[0118] S440, the target field in the service message is acquired according to the position information.

[0119] S450, the logical core identifier corresponding to the service message is determined according to the target field, the service channel identifier, the number of distributed messages and the number of logical cores in the first logical core group.

[0120] Exemplarily, the target field is a basic hash value obtained after the service packet is processed by a front-stage processing unit of the service packet. The position and value of the basic hash value are different for different types of packets. The basic hash value can be obtained from the service packet through the association between the type of the service packet and the position information of the basic hash value. The service channel identifier is carried in the service packet, and the service channel identifier can be obtained by analyzing the service packet. Since the micro-processing core records the number of distributed packets through a counter, the number of distributed packets can be obtained by querying the counter in the micro-processing core. Then, the hash algorithm in the code of the micro-processing core is used to calculate the hash value of the service packet based on the basic hash value, the service channel identifier, the number of distributed packets, and the number of logical cores in the first logical core group, and the hash value of the service packet is used as the logical core identifier.

[0121] S460, determining a first logical core from the first logical core group according to the logical core identifier, and distributing the service packet to the first logical core for processing.

[0122] S470, polling a second logical core group through a micro-processing core corresponding to the management channel, and determining a logical core identifier according to a polling result.

[0123] The second logical core group includes logical cores for processing management packets, and the second logical core group can be composed of logical cores corresponding to micro-processing cores allocated to the management channel.

[0124] Since the micro-processing cores dedicated to processing management packets are pre-configured, if the number of micro-processing cores is 1, the management packets of all management channels are distributed by the micro-processing core.
