It should be understood that the embodiments of the present application and the specific features in the embodiments are a detailed description of the technical solution of the present application, and This is not intended to limit the technical solution of the present application. If there is no conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

It should be understood that in the description of the embodiments of this application, words such as "first" and "second" are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating. Or suggestive order. In the description of the embodiments of this application, "multiple" means two or more.

The term "and/or" in the embodiment of this application is only an association relationship describing associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A alone exists, and A and A exist simultaneously. B, there are three situations of B alone. In addition, the character "/" in this article generally indicates that the related objects are an "or" relationship.

In order to facilitate understanding of the solutions of the embodiments of the present application, possible application scenarios of the embodiments of the present application are first introduced below.

Embodiments of the present application can be used for various types of network cards, such as network cards that support Data Plane Development Kit (DPDK) services, or other devices. As long as the device has a need to transmit messages to the CPU, the technical solutions in the embodiments of the present application can be adopted. For ease of description, this article takes a network card that supports DPDK as an example.

Most application services developed based on DPDK use network card multi-queue, multi-core CPU bound queue and other technologies to improve network throughput performance. DPDK application services use kernel bypass technology, and independent application protocol stack traffic passes through the network card and directly enters the application program for processing, without going through the operating system kernel Linux network protocol stack. Business traffic (specifically refers to the service traffic processed by the application, which is generally VIP service traffic) and control traffic (specifically refers to all non-VIP service traffic including all host IPs, Border Gateway Protocol (BGP)/Shortest Path First (Open Shortest) Path First, OSPF)/health check and other traffic) are mixed in different network card queues for reception and processing.

For example, see Figure 1, which is a schematic diagram of a scenario applicable to the embodiment of the present application. The DPDK network card can receive messages (the types of messages include business messages and control messages) and distribute the messages to the network card queue. , where different network card queues correspond to different CPU cores. After the CPU core receives the message, it processes the message and transmits the processed message to the corresponding process. It is understandable that different CPU cores in this article can be integrated on different CPU physical entities, or can be integrated in different CPU physical entities. For the convenience of description, this article uses the example that one CPU core is a CPU for description.

Among them, different types of messages need to be transmitted to different processes. For example, business messages need to be transmitted to the forwarding process, and control messages need to be transmitted to the control packet process.

One possible implementation is to separate business packets and control packets at the CPU. In other words, there may be both business packets and control packets in the same network card queue, and the same CPU may process both business packets and control packets. The first network card queue also processes control packets. As shown in Figure 2, the first network card queue carries both business packets and control packets. CPU1 processes both business packets and control packets.

However, in actual applications, the traffic of business packets changes dynamically. When business packets surge and business packets and control packets share the network card queue, problems such as delay and loss of control packets will occur in the network card, which in turn affects the business. of normal operation.

In view of this, the technical solution of the embodiment of the present application is provided to realize the separation of service messages and control messages at the network card, so that the service messages and control messages are carried in different network card queues respectively, and are respectively carried by different network card queues. The CPU performs processing to avoid problems such as delay and loss of control messages.

Refer to Figure 3, which is a flow chart of a message transmission method provided by an embodiment of the present application. The method is applied to the scenario shown in Figure 1 as an example. The specific steps of the method are as follows:

Step S301: The network card receives the first service message and the first control message.

Generally, packets carry five-tuple information, including source address, destination address, source port number, destination port number, and protocol number. The embodiments of this application do not limit the type of packets. For convenience of description, this article takes IP packets as an example. Correspondingly, the source address, destination address, source port number, and destination port number are: source IP address, destination IP address, source Transmission Control Protocol (TCP)/User Datagram Protocol (UDP) ) port number, destination TCP/UDP port number.

In this embodiment of the present application, the first service packet carries the first five-tuple information, and the first control packet carries the second five-tuple information.

Among them, the type of the destination address in the first quintuple information is VIP; the type of the destination address in the second quintuple information is not VIP, or it is an address of other types besides VIP, such as Host Identification Protocol ( Host Identity Protocol, HIP) address. For example, the five-tuple information of the first service message can be expressed as S1 = (SIP, VIP, SPORT, DPORT, PROTO), where SIP, VIP, SPORT, DPORT, and PROTO respectively represent the source IP address of the first service message. , destination IP address, source port number, destination port number, protocol number; the five-tuple information of the first control message can be expressed as S2 = (SIP, HIP, SPORT, DPORT, PROTO), where SIP, VIP, SPORT, DPORT and PROTO respectively represent the source IP address, destination IP address, source port number, destination port number, and protocol number of the second service message, where the protocol number can be the protocol number of the transport layer protocol.

Step S302: The network card distributes the first service packet to the first network card queue based on the first five-tuple information; the network card distributes the first control packet to the second network card queue based on the second five-tuple information.

Among them, the first network card queue is used to transmit service packets (not to transmit control packets), and the second network card queue is used to transmit control packets (not to transmit business packets).

Specifically, the network card determines that the message type of the first service message is a service message based on the type of the destination address in the first five-tuple information (ie, VIP), and distributes it to the network card queue used to transmit the service message. superior. Based on the type of the destination address (such as HIP) in the second five-tuple information, the network card determines that the message type of the second service message is a control message, and distributes it to the network card queue used to transmit the control message.

In one possible implementation, the number of network card queues used to transmit service packets in the network is one, such as the first network card queue, and the network card directly distributes the first service packet to the first network card queue.

In a possible implementation, the number of network card queues used to transmit service packets in the network is multiple (for example, the first network card queue is one of the network card queue groups, and the network card queue group includes multiple network card queues, and multiple network card queues are included in the network card queue group. (the network card queue group does not include the second network card queue), the network card needs to further determine the first network card queue from these multiple network card queues, and then the network card distributes the first service packet to the first network card queue.

In one possible design, the network card determines the first network card queue from multiple network card queues, including: the DPDK network card calculates the hash value of the first five-tuple information and obtains the hash value h; and then performs the hash value h on the hash value h. Calculate the remainder: h%N to obtain the first value, where N is a preset value; then determine the identity of the first network card queue from the redirection table based on the first value; wherein the redirection table includes N entries; Each entry among the N entries corresponds to the identifier of a network card queue; the first value is used to indicate one of the N entries. Furthermore, the network card can distribute the first service packet to the first network card queue according to the identifier of the first network card queue. This method determines the first network card queue by querying the redirection table, and is simple and easy to implement.

In specific implementation, the process of the network card distributing the first service message to the first network card queue can be implemented based on RSS. RSS is a technology that can distribute the message by performing hash calculation on the five-tuple information, which can be implemented Forward different packets to multiple different CPUs in a load-balanced manner. Considering that different network cards have different default redirection table lengths, in specific applications, if the number of business processes does not match the length of the redirection table (that is, the number of table entries), you need to modify the redirection table. Perform a reset before using.

For example, taking the 82599 model network card and the number of service processes as 16:

In the first step, the length of the redirection table corresponding to the 82599 model network card is 64, and the entries in the redirection table are taken from 0 to 63; the number of business processes is 16, so 16 network card queues need to be configured, and the values of the network card queue numbers are in order is 0 to 15; perform remainder calculation on each entry in the redirection table based on the number of processes, that is, take the remainder of 16 from 0 to 63, and write the remainder result as the network card queue number corresponding to each entry in the redirection table to get the reset redirection table. According to the remainder result, the network card queue numbers corresponding to the 0 to 15 table entries are 0 to 15, the network card queue numbers corresponding to the 16 to 31 table entries are 0 to 15,..., and so on, so that the reset redirection table The network card queue number corresponding to each entry is one from 0 to 15.

The second step is to calculate the hash value of the first service message. Assume that the hash value is 63. The remainder of the hash value 63 is taken according to the length of the redirection table, that is, the remainder is 63% 64. The remainder result is 63. The query is repeated. If there is an entry corresponding to 63 in the configured RSS redirection table, and the network card queue number corresponding to this entry is 15, it is determined that the first service packet will be distributed to the network card queue number 15.

In one possible design, the network card distributes the first control message to the second network card queue based on the second five-tuple information, including: the network card determines that the destination address in the second five-tuple information is the preset destination address; The destination port number is a preset port number and the protocol number is a preset protocol number; the network card binds the first control message to the second network card queue, and the second network card queue transmits the first control message to the second CPU.

In specific implementation, the process of the network card distributing the first control message to the second network card queue can be implemented based on Flow Director or Rte_Flow. Flow Director or Rte_Flow is a network card queue that can match special fields in the message and decide to transmit the message. Technology in which special fields can be used as packet matching rules.

Specifically, configure message matching rules on the network card based on Flow Director or Rte_Flow. The message matching rules include the destination address, destination port number, and protocol number corresponding to the control message, represented by S=Match{DIP,DPORT,PROTO}.

For example:

S _OSPF =Match{224.0.0.5,0,0};

S _BGP =Match{hip,179,6};

_SHIP =Match{hip,0,0}.

Among them, DPORT=0 means all ports, PROTO=0 means all protocols, BGP uses port 179 for the TCP protocol, and the TCP protocol has a field of 6 in the IP header.

Among them, S _HIP traffic includes S _BGP traffic. The S _BGP configuration here shows how users can customize the port configuration. S _HIP traffic also includes Secure Shell Protocol (Secure Shell, SSH) remote login traffic.

After the setting is completed, the control traffic sent to OSPF, BGP and the management port host IP can be received by the second network card queue.

It can be understood that the above example takes the number of network card queues used to transmit control messages as 1. In actual applications, the number of network card queues used to transmit control messages can also be multiple, thereby further improving the transmission efficiency of control messages. .

Furthermore, different network card queues in the embodiment of this application are bound to different CPUs, and different CPUs transmit messages to different processes. Exemplarily, the first network card queue corresponds to the first CPU, the first network card queue is used to transmit service packets to the first CPU, and the first forwarding process binds the first CPU to process the first service packet; the second network card queue corresponds to The second CPU and the second network card queue transmit the control packet to the second CPU, and the first control process binds the second CPU to process the first control packet.

For example, see Figure 4, NIC queue 0 to NIC queue n correspond to CPU0 to CPUn respectively, in which NIC queue 0 to NIC queue n-1 are used to carry service packets, and NIC queue n is specially used to carry control packets.

Through the above solution, the business packets and control packets can be separated at the network card, so that the business packets and control packets are carried in different network card queues and processed by different CPUs respectively to avoid business packets The surge will cause problems such as packet transmission delays and loss.
