Description
Technical Field
The present application relates to the field of network communication technologies, and in particular, to a method and an apparatus for processing a packet.
Background
The Smart NIC, i.e., the Smart network card, completely transfers the virtual switch function from the server CPU to the network card, freeing up the expensive computing power of the server CPU to return to the application, thereby better extending the network card functionality and providing higher performance.
Because the forwarding mechanisms of the intelligent network card and the common network card are different, the intelligent network card is bypass kernel, the memory of the virtual machine and the memory of the intelligent network card are directly mapped, and the common network card is written to the memory mapped by the network card through the kernel, so that the intelligent network card and the common network card cannot be aggregated at present.
At present, in order to reduce the cost, the port rate of some models of the smart cards is lower than the chip forwarding rate, for example, the port is 2 × 25G — 50G, and the chip forwarding rate is 100G, so that the smart card has a bandwidth of 50G to be idle.

As used in this application and the claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
Exemplarily, referring to fig. 1, a detailed flowchart of a message processing method provided in an embodiment of the present application is shown, where the method is applied to an intelligent network card, a network device configured with the intelligent network card is also configured with a common network card, the intelligent network card is connected to a virtual machine created on the network device, the intelligent network card and the common network card are connected to an external device, and a transmission buffer of the common network card is configured in a memory of the network device, and the method includes the following steps:
step 100: the intelligent network card acquires the memory address information of the sending buffer area.
In the embodiment of the application, when the network device is initialized, the network card driver acquires the memory address information of the transmission BUFFER (e.g., TX BUFFER RING) of the common network card, and notifies the acquired memory address information of the transmission BUFFER to the intelligent network card.
It should be noted that the network card driver is a network card driver that can drive an intelligent network card deployed on a network device and, at the same time, can drive a common network card deployed on the network device. The TX BUFFER RING is essentially a RING consisting of a series of small blocks of memory, and each message may occupy several small blocks of memory because the address of the TX BUFFER RING written in the smart card is the starting address of the currently idle memory block. After the intelligent network card sends a message to the TX BUFFER RING, the starting address needs to be modified and shifted to the starting address of the new idle memory block, so that the message which is sent just before is prevented from being covered by other messages before being sent by the common network card.
In practical application, after sensing that the transmission buffer changes (i.e. after buffering the message to be transmitted), the DMA sends the message buffered by the transmission buffer out from the physical port of the common network card.
Step 110: the intelligent network card establishes a first logic port, establishes a connection relation between the first logic port and the sending buffer area based on the memory address information of the sending buffer area, and forms an aggregation port by the first logic port and a local physical port.
In this embodiment, after obtaining the sending buffer area of the normal network card, the intelligent network card locally creates a first logical port, where the first logical port is used to point to a memory address of the sending buffer area of the normal network card, that is, the first logical port and the sending buffer area of the normal network card establish a connection relationship, the first logical port can send a message to the sending buffer area of the normal network card, and further, the intelligent network card forms an aggregation port by using the first logical port and a physical port locally used for sending the message, and both the aggregation port and the physical port are used for message sending processing.
Step 120: and when receiving a first message sent by the virtual machine, the intelligent network card determines a target port for sending the first message from the aggregation port based on the communication address information of the first message, and sends the first message to an external device through the target port.
In this embodiment of the present application, when determining, based on the communication address information of the first packet, a destination port for sending the first packet from the aggregation port, and sending the first packet to an external device through the destination port, a preferable implementation manner is:
and the intelligent network card performs hash calculation according to the MAC and/or IP address information of the first message, and determines a target port for sending the first message from the first logic port and the local physical port according to a hash result.
As can be seen from the above, the aggregation port includes a local physical port on the smart network card and the first logical port, and then the determined target port may be the local physical port, or the determined target port may be the first logical interface.
And if the intelligent network card determines that the target port is the local physical port, the first message is sent to external equipment through the physical port.
If the intelligent network card determines that the target port is the first logical port, the first message is sent to the sending cache area through the first logical port, so that the common network card sends the first message to an external device from a local physical port of the common network card.
Exemplarily, referring to fig. 2, a networking connection diagram provided for the embodiment of the present application is shown, where an intelligent network card, a common network card, a virtual machine, a sending buffer of the common network card and a network card driver are deployed on a network device, a first logical interface of the intelligent network card is connected to the sending buffer of the common network card, the intelligent network card is connected to the virtual machine, the intelligent network card is connected to the common network card and an external switch, and the first logical interface of the intelligent network card and a local physical port for sending a message form an aggregation port.
Then, when the virtual machine sends a message, the message sending process of the network device is as follows: when a virtual machine deployed in network equipment sends a message, according to the processing logic of the intelligent network card, the message bypasses (bypass) an inner core to reach the intelligent network card, a flow table on the intelligent network card is inquired, an output port of the flow table is a polymerization port, the intelligent network card performs hash processing according to information such as MAC (media access control), IP (Internet protocol) and the like of the message, the message hashed to a local physical port is directly sent out from a physical port of the intelligent network card, the message hashed to the logical port is sent to a sending buffer zone through the logical port, then the message is sensed by a DMA (direct memory access) of a common network card, and the message is sent out from a physical port of the common physical network card.
Further, in this embodiment, a receiving buffer of the common network card is further configured in the memory of the network device; the above method further comprises the steps of:
the method comprises the following steps: and the intelligent network card acquires the memory address information of the receiving buffer area.
Specifically, the network card driver may still be configured to acquire the memory address information of the receiving BUFFER (e.g., RX BUFFER RING) of the common network card, and notify the intelligent network card of the memory address information of the receiving BUFFER, so that the intelligent network card acquires the memory address information of the receiving BUFFER.
Step two: and the intelligent network card establishes a second logic port and establishes a connection relation between the first logic port and the receiving buffer area based on the memory address information of the receiving buffer area.
Further, the intelligent network card creates a new second logical port, or the second logical port may also be the first logical port, that is, in this embodiment of the application, the second logical port and the first logical port are the same logical port, and a connection relationship between the second logical port and the receiving buffer of the ordinary network card is established, that is, the intelligent network card may obtain the cached message from the receiving buffer of the ordinary network card through the second logical port.
Step three: and when receiving an interrupt request sent by the common network card, the intelligent network card acquires a second message from the receiving buffer area through the second logic port and sends the second message to the corresponding virtual machine, wherein when receiving the second message sent by the external equipment and caching the second message to the receiving buffer area, the common network card sends the interrupt request to the intelligent network card.
For example, referring to fig. 3, another schematic diagram of networking connection provided for the embodiment of the present application is shown, where an intelligent network card, a normal network card, a virtual machine, a sending buffer area of the normal network card, and a network card driver are deployed on a network device, a second logic interface of the intelligent network card is connected to a receiving buffer area of the normal network card, the intelligent network card is connected to the virtual machine, and the intelligent network card, the normal network card, and an external switch are connected.
Then, when the local physical port on the intelligent network card receives the message sent by the switch, the message is directly forwarded to the corresponding virtual machine, and when the common network card receives the message sent by the switch, the message processing process is as follows:
specifically, the intelligent network card suspends packet receiving interruption of the ordinary network card to the CPU of the intelligent network card, so that when the ordinary network card receives a message and caches the message in the receiving BUFFER, the intelligent network card receives an interruption request, further reads the message from the RX BUFFER RING, and forwards the message to the corresponding virtual machine by looking up the flow table.
Further, in this embodiment of the present application, the message processing method may further include the following steps: and when determining that the utilization rate of the sending buffer area is greater than a first set threshold value, the intelligent network card takes the local physical port in the aggregation port as a target port and sends the received first message sent by the virtual machine to external equipment through the local physical port.
And when determining that the usage rate of the transmission buffer is smaller than a second set threshold, the intelligent network card performs a step of determining a destination port for transmitting the first message from the aggregation port based on the communication address information of the first message, and transmitting the first message to an external device through the destination port, wherein the second set threshold is smaller than the first set threshold.
That is, when the usage rate of the sending BUFFER is greater than the first set threshold, for example, the sending BUFFER is full and no more usable BUFFER is available, at this time, the virtual port corresponding to the common network card may be set to not participate in the hash, so that the subsequent message is not sent to the common network card. And setting the logic port corresponding to the common network card as the joining hash again until the common network card sends the current message of the sending BUFFER zone completely, and setting the logic port corresponding to the common network card as the joining hash again, so that the message sent by the subsequent virtual machine can still be hashed to the common network card.
