Detailed ways

The application will be described in detail below in conjunction with the accompanying drawings and embodiments.

Any embodiment or design solution described as "optional" or "exemplary" in the embodiments of the present application shall not be interpreted as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "optional" or "exemplary" is intended to present related concepts in a concrete manner.

Figure 1 is a schematic flow chart of the flow migration method of the embodiment of the present application. The method can be executed by the flow migration device provided by the embodiment of the present application. The device can be implemented by software and/or hardware. In a specific embodiment In this example, the device may be integrated in an electronic device, and the electronic device may be a network card. In this embodiment, the integration of the traffic migration device in the network card is used as an example for illustration.

Fig. 1 is a schematic flow chart of the traffic migration method of the embodiment of the present application, which is applied to the traffic migration system. The traffic migration system includes a switch, a network card, and a target server. The network card is installed on the target server, and the target server has multiple cache queues and corresponding Multiple processing processes, each processing process processes the data cached in the corresponding cache queue, the method includes the following steps:

S110. The network card receives the data to be processed distributed by the switch.

Wherein, the network card is a network processor architecture for multi-core and multi-thread, and realizes features such as virtual switching. For example, it may be a plug-in network card, or may be a snap-in network card, etc., which is not limited in this embodiment. A switch is a device that performs an information exchange function in a communication system. For example, it may be an Ethernet switch, or may be a fiber optic switch, which is not limited in this embodiment. The data to be processed can be accessed from the outside, such as the operator, or it can be generated by the internal structure, such as building a network and directional input traffic.

Wherein, the network card is attached to the target server, and each target processor is equipped with a network card. The target server is mainly set up for packet acceleration processing and traffic management. Among them, the target server generally uses a general-purpose x86 server as its basic form, and business-related applications use the basic hardware resources provided by it to run normally. For example, it can be a central processing A central processing unit (CPU), a dynamic random access memory (Dynamic Random Access Memory, DRAM), or a hard disk drive (Hard Disk Drive, HDD), etc., which is not limited in this embodiment.

Exemplarily, the switch evenly distributes the data traffic to multiple target servers, and then the target servers receive the data traffic through the network card.

S120. The network card calculates the first target cache queue to which the data to be processed should be distributed according to the additional information of the data to be processed.

Among them, the additional information includes input port information, source Media Access Control MAC (Media Access Control) address, destination MAC address, network type, network identification number, source Internet Protocol Address (Internet Protocol Address) address, and destination IP address At least one of , IP port information, source Transmission Control Protocol TCP (Transmission Control Protocol) port information and target TCP port information.

Among them, the cache queue is a buffer for storing pre-allocated data traffic. Generally, a target server will load a network card. In the case of a large amount of data traffic access, a single cache queue may not be able to meet the performance requirements. Requirements, so that multiple cache queues can be divided, and one cache queue is determined from the multiple cache queues as the first target cache queue according to the additional information of the data to be processed, and the remaining cache queues are other cache queues.

S130. The network card determines the cache status of the first target cache queue.

Exemplarily, when the network card wants to store the data traffic into the first target cache queue, it needs to determine whether the cache status of the first target cache queue can store the data traffic. Among them, a processing process can process a cache queue. If the processing process corresponding to a certain cache queue is killed by the operating system, such as a code error, memory access out of bounds, etc., an exception will occur in the processing process at this time, resulting in the generation of the cache queue. Backlog, the NIC detects that the cache queue is full in time; if the processing process can continue to process normally, it will display that the cache status is not full; that is, the status of the cache queue reflects the status of the corresponding processing process.

Exemplarily, when the network card now needs to store the existing data traffic into the first target cache queue, and the processing process corresponding to the first target cache queue is normal, and there is no backlog in the cache queue, then the network card determines that the first target cache queue The cache status of a target cache queue is ready to store data traffic.

S140. When the cache state of the first target cache queue is fully loaded, the network card determines the second target cache queue according to the cache states of other cache queues, and the other cache queues are caches other than the first target cache queue among the multiple cache queues queue.

Wherein, for all target cache queues, if one target cache queue is determined to be the first target cache queue, then the remaining cache queues are called other cache queues. Exemplarily, when the cache state of the first target cache queue is fully loaded, it can Among other cache queues, a second target cache queue is determined.

As shown in Figure 2, Figure 2 is a schematic diagram of traffic migration in the target server of the embodiment of the present application, there are n cache queues in total, assuming that the first target cache queue is cache queue 1, when the cache state of the first target cache queue is In the full state, that is, the first target cache queue can no longer receive new data traffic, and the corresponding processing process can no longer be processed, resulting in a backlog in the first target cache queue. At this time, the same method as S130 needs to be used to determine other cache queues again The second target cache queue is determined in 2-n cache queues except the first target cache queue according to the cache status of other cache queues. Corresponding to Figure 2, the network card determines to distribute the data to be processed to the cache queue 1 as shown by the black arrow. When the cache queue 1 is fully loaded, the cache queue 1 cannot continue to be stored at this time, and the network card judges that the cache queue 2 and cache queue n can be processed. The data traffic is cached, and the data to be processed is cached in cache queue 2 and cache queue n respectively, as shown in the black boxes in cache queue 2 and cache queue n in Figure 2.

Releasing the full load of a single cache queue mainly depends on the daemon program of the data processing node, which can continuously monitor the running status of the program. After the full load occurs, such as the error of the memory out of bounds segment mentioned above, the program can be restarted. The release of the full cache queue mainly depends on the system. For example, the server is powered off and the port is disconnected from the switch. When the power failure is restored, the server will automatically execute the program startup script after startup to restore the normal operation of the target server. The switch detects that the processing process of the cache queue starts processing The traffic will then be forwarded back.

Exemplarily, when the initial data flow storage capacity of each cache queue is set to 8, if the current 8 data flow storage spaces of the first target cache queue are all occupied, the cache status of the first target cache queue will be The second cache queue can be determined from other cache queues. For example, if there is a cache queue in other cache queues, and two of its 8 data flow storage spaces are occupied, then the cache queue can be determined as The second target cache queue, there is no backlog in the second target cache queue.

S150. The network card distributes the data to be processed to the second target cache queue.

Exemplarily, when it is determined that the second target cache queue is not fully loaded, that is, there is no backlog of data traffic, and the processing process is processing data traffic normally, then the network card distributes the data to be processed to the second target cache queue.

Optionally, the traffic migration system also includes a backup server, and the method also includes: when the network card cannot determine the second target cache queue according to the cache states of other cache queues, the network card returns the data to be processed to the switch, so that the switch will Pending data is distributed to standby servers.

Wherein, the standby server may be the same server as the target server, or may be a different server, which is not limited in this embodiment.

Exemplarily, when the network card cannot determine the second target cache queue according to the cache status of other cache queues, that is to say, when the second target cache queue is determined according to the cache status of other cache queues, the remaining target cache queues are all fully loaded state, the data to be processed can no longer be received. At this time, the data traffic to be accessed is returned to the switch, and then the switch distributes the data to be processed to the standby server for further processing.

As shown in Figure 3, Figure 3 is a schematic diagram of traffic migration to a backup server according to the embodiment of the present application; when all target cache queues in the target server are fully loaded or the instantaneous data traffic is much greater than the performance of the target server For a limited time, the network card will not discard the subsequent received traffic, but will forward the traffic to the standby server through the switch.

The technical solution of the embodiment of the present application provides a flow migration method, which receives the data to be processed distributed by the switch through the network card, and uses the network card to calculate the first target cache queue to which the data to be processed should be distributed according to the additional information of the data to be processed; the network card determines The cache status of the first target cache queue; when the cache status of the first target cache queue is fully loaded, the network card determines the second target cache queue according to the cache status of other cache queues, and the other cache queues are the multiple cache queues except the first A cache queue other than the target cache queue; the network card distributes the data to be processed to the second target cache queue. That is, in the embodiment of the present application, a flexible load balancing strategy can be achieved through the network card using its own computing power to migrate traffic, and the traffic received by the data nodes is more stable and balanced. That is to say, in the embodiment of the present application, the network card installed on the device can be used for traffic distribution, and the balanced distribution of traffic can be realized, and the high-performance programmable capability of the network card can be used to realize the sudden traffic migration. When the process) is abnormal, traffic migration can be performed through the network card installed on the device, thereby avoiding traffic being discarded, ensuring the normal operation of the business, and improving the user's business experience.

Exemplarily, on the basis of the foregoing embodiments, the result of traffic migration performed by the network card according to the data to be processed is refined.

Fig. 4 is a schematic flowchart of another traffic migration method according to an embodiment of the present application. As shown in Fig. 4, the method includes:

S410. The network card receives the data to be processed distributed by the switch.

That is, the data to be processed received by the network card is distributed by the switch. For example, the switch can maintain a data distribution table and distribute the data to be processed according to the data distribution table. The entries in the data distribution table are generally 256, 512 or 1024. For example, The data distribution table maintained in the switch can be shown in Table 1 below:

索引index	网口Network port
00	00
11	11
22	22
……	……
1515	1515
1616	00
1717	11
……	……
10231023	1515

Table 1

As shown in Table 1, that is, the entry is 1024, which needs to be distributed to 16 network ports (network cards), then for a piece of data to be processed, it can be analyzed to obtain the source IP and destination IP, both of which are 32bit The value needs to be processed to correspond to the entry (1024 entries represent 10bit). The general processing is xor, which means XOR operation, namely:

(1) Source IP xor destination IP gets a 32bit value;

(2) Take the high 16-bit xor low 16-bit value of the value obtained in step (1) to obtain a 16-bit value;

(3) Use 15-12bits and 11-8bits xor of 16bits to replace the obtained 4bits with 11-8bits to obtain 12bits;

(4) The 12bit value is shifted to the right by 2 bits (remove the lower 2 bits) to obtain a 10bits hash value.

The data distribution table maintained in the switch is queried according to the obtained hash value, so as to determine to which network port the data to be processed is distributed, and thus the data to be processed is distributed to the corresponding network port. For example, if the hash value of certain data to be processed calculated by the switch according to the above rules is 15, the lookup table 1 determines that the data to be processed can be distributed to the network port 15 .

S420. The network card performs hash calculation on the additional information of the data to be processed to obtain a hash value.

Among them, the hash calculation is also called the hash algorithm, which is to give an input channel through the hash algorithm to output a fixed length, mainly to transform the input of any length into a fixed-length output through the hash algorithm, the output is hash value. This conversion is a compression mapping, that is, the space of the hash value is usually much smaller than the space of the input, different inputs may be hashed into the same output, and it is impossible to uniquely determine the input value from the hash value. Simply put, it is a function to compress a message of any length into a fixed-length message digest.

Among them, the hash value can be understood as the identity of a piece of traffic data. Through a certain hash algorithm, for example, it can be MD5 message digest algorithm (MD5Message-Digest Algorithm, MD5), or it can be secure hash algorithm 1 (Secure Hash Algorithm 1, SHA-1), etc., which are not limited in this embodiment.

Exemplary, the additional information of the data to be processed by the network card, such as input port information, source media access control MAC address, destination MAC address, network type, network identification number, source Internet Protocol IP address, destination IP address, IP At least one of port information, source transmission control protocol TCP port information and target TCP port information is hashed, and a long piece of data is mapped to a short piece of small data. This piece of small data is the hash of big data. Hash value, and it is unique, once the big data changes, even if it is a small change, its hash value will also change.

S430. Determine the first target cache queue according to the hash value.

For example, a data distribution table may also be maintained in the network card, and the data distribution table maintained in the network card may be shown in Table 2 below:

索引index	缓存队列cache queue
11	11
22	22
33	33
……	……
77	11
88	22
99	33
……	……

Table 2

As shown in Table 2, that is, the data needs to be distributed to three cache queues. After the network card calculates the hash value of the data to be processed according to the above rules, it can query the data distribution table maintained in the network card to determine the first queue where the data to be processed should be distributed. A target cache queue. For example, for a certain data to be processed, if the hash value calculated by the network card is 2, the data distribution table maintained in the network card can be queried to determine that the data to be processed needs to be distributed to the cache queue 2.

S440. The network card determines whether the first target cache queue is fully loaded.

Exemplarily, for example, when the original fixed buffer value of the first target buffer queue is 8 bits, the value equal to 8 bits is a full load state, and less than 8 bits is a non-full load state.

S450. The network card distributes the data to be processed to the first target cache queue.

Exemplarily, corresponding to a target cache queue, a processing process of a target server is used for processing. The non-full load state is when the processing process normally processes the data traffic of the first target cache queue and can continue to buffer the data traffic. At this time, it can Distribute the data to be processed to the first target cache queue for processing.

Exemplarily, if the total number of caches in the first target cache queue is 8, for example, if the number of caches in the first target cache queue is currently 4 in a non-full state, there are 4 data flows in the network card that need to be distributed to the cache queue. There is buffer space in the first target cache queue, and the 4 data flows to be processed can be distributed to the first target cache queue.

S460. The network card determines a second target cache queue according to cache states of other cache queues, where the other cache queues are cache queues other than the first target cache queue among the multiple cache queues.

Exemplarily, when the cache status of the first target cache queue is full, that is, when the processing process is processing data traffic, there is a backlog in the processing of the cache queue by the processing process, and the network card promptly distributes the subsequent files to the first target cache queue. The data flow of a target cache queue is recalculated and the hash result is distributed to other cache queues, that is, the second target cache queue is determined in other cache queues, and the original distribution method is restored after the cache queue is fully loaded. Among them, the full load of the cache queue mainly depends on the daemon program of the target server, which can continuously monitor the running status of the program. Usually, when the cache queue is full, such as a memory out-of-bounds segment error, the full load can be relieved by restarting the program.

S470. The network card distributes the data to be processed to the second target cache queue.

As an optional solution in this embodiment, the network card determines the second target cache queue according to the cache status of other cache queues, including: the network card finds that the cache status is not fully loaded from other cache queues, and the amount of cached data is less than a preset Threshold cache queue to get the second target cache queue.

Among them, the preset threshold is a theoretical upper limit. In many cases, it is affected by traffic or hardware. It can be a dynamic upper limit for identification. Within a period of time, there is a threshold that reaches the upper limit for a certain time. It can be considered to have reached the upper limit of the preset threshold.

Exemplarily, when the first target cache queue is fully loaded, the network card determines whether the cache status of other cache queues is full or not full according to the cache status of other cache queues except the first target cache queue, and the cache queue The number of caches is 8, if it is less than 8, it is judged as not fully loaded, and when it is equal to 8, it is judged as fully loaded. When it is judged to be in a non-full load state, determine the cached data volume of the data to be processed. If the determined cacheable data volume of the non-full-loaded cache queue is 4, and the data volume of the data to be processed is less than 4 or equal to 4, the second Target cache queue; if the amount of data to be processed is greater than the cacheable data volume 4 of the cache queue, continue to determine the second target cache queue in the remaining other cache queues.

The technical solutions of the embodiments of the present application provide a traffic migration method, wherein the network card receives the data to be processed distributed by the switch. The network card performs hash calculation on the additional information of the data to be processed to obtain the hash value; determines the first target cache queue according to the hash value; when the cache state of the first target cache queue is not fully loaded, the network card distributes the data to be processed to The first target cache queue; the network card determines the cache status of the first target cache queue; when the cache status of the first target cache queue is fully loaded, the network card determines the second target cache queue according to the cache status of other cache queues, and the other cache queues are A cache queue other than the first target cache queue among the multiple cache queues; the network card distributes the data to be processed to the second target cache queue. That is, in the embodiment of the present application, the hash value is used to determine the first target cache queue, thereby successfully implementing traffic migration and ensuring that the traffic received by the data nodes is more stable and balanced.
