One or more embodiments of the present application will be described below with reference to the accompanying drawings.
Based on the above objects, a first aspect of the embodiments of the present invention proposes an embodiment of a method for controlling a data flow of a multihost network card. Fig. 1 is a schematic diagram of a method for controlling data flow of a multihost network card according to the present invention. As shown in fig. 1, a method for controlling data traffic of a multihost network card according to an embodiment of the present invention includes the following steps:
s1, establishing a data flow control layer between a MAC layer and a SERDES layer of a multi host network card;
s2, establishing identification of a source MAC of the MAC layer by the data flow control layer to obtain the flow demand of the data of the source MAC;
s3, establishing connection of different SERDES interfaces of the data flow control layer and the SERDES layer;
and S4, the data flow control layer forwards the data of the source MAC to a corresponding SERDES interface for transmission according to the flow demand of the data of the source MAC.
Fig. 2 is a schematic diagram of another embodiment of a method for controlling data traffic of a multihost network card according to the present invention.
In the existing multihoming application scenario, when the bandwidth of the multihoming network card is 100G, four CPUs of the four-way server are connected to the pci ex16 of the multihoming network card by the lane of the pci ex4, so that the four CPUs are allocated with four MAC addresses at the OS layer. Each CPU corresponds to one MAC address, the MAC addresses can access the multi-host network card, data transmission is carried out from the physical network port of the multi-host network card, and all MAC share the physical network port. The multi host network card presents addresses corresponding to 4 CPUs in the upper OS, different application data can call different MAC addresses for data transmission, for example, program 1 calls MAC1, and program 2 calls MAC2 for analogization. Although the sending port of the multi-host network card is also 4 SERDES interfaces (each SERDES is a fixed flow of 25G), the 4 SERDES interfaces only send data transmitted by all MAC layers in parallel, do not distinguish specific data streams, namely, transmit data to the outside at the physical port of the multi-host network card, send the data according to a queue sequence, and cannot control the flow of the data. However, on the multipath server, the user can use multiple services, and there is a priority difference, that is, there is a service that is important to send data in time, and a service that is not important to wait, and flow control is required according to the service requirement. Therefore, in this case, the multihost network card cannot distinguish the data stream and perform data flow control, and only can transmit data according to the sequence of the data packet, which affects the actual service application of the user.
The method for controlling the data flow of the multi-host network card provided by the invention is designed for separating the data flow in a hardware layer, namely a data flow control layer is additionally arranged between an MAC layer and an SERDES layer of the multi-host network card, and the data of specific flow is sent to the specific SERDES and then sent to a network through the data flow control layer.
In this embodiment, the mode of sequential transmission in the prior art is broken, a data flow control layer is added at the back end of the MAC layer, and the data flow control layer performs data distribution according to the upper MAC address, for example, controls the data flow direction of the data flow control layer, and then forwards the data of the upper MAC to the corresponding SERDES interface according to the data flow control requirement. The SERDES which is sent by the specific MAC is set by a data flow control layer of hardware, so that a user can better adjust according to own service requirements, important service data can occupy sufficient bandwidth, the bandwidth is shared independently, and timely and stable sending of the important service data is ensured.
And establishing the identification of the source MAC of the MAC layer by the data flow control layer to obtain the flow demand of the data of the source MAC. Because the ethernet data packet outermost layer is an ethernet header, the ethernet header is sequentially a destination MAC (MAC for receiving data, occupying the first 6 bytes), a source MAC (MAC for transmitting data, occupying the middle 6 bytes), a type (upper protocol type, occupying 2 bytes), and the like, the source MAC needs to be identified at the data flow control layer (directly skipping the 6 bytes of the destination MAC), and then the data flow of the source MAC is forwarded as required.
A plurality of configuration modules are established in a data flow control layer, and connection between the configuration modules and different SERDES interfaces of the SERDES layer is established respectively so as to transmit data. In this embodiment, the data bandwidth of the port of the multihost network card is 100G, and there are a total of 4 SERDES interfaces, namely serdes_1, serdes_2, serdes_3, and serdes_4, and the data traffic of each SERDES interface is 25G per second. The data importance of mac1 and mac2 is not high, but the data importance of mac3 and mac4 is high, so that the data of mac3 and mac4 need to be sent preferentially, meanwhile, the data bandwidth requirement of mac4 is high, and the following allocation can be performed according to the above traffic requirement at the traffic control layer: the data sent for mac1 and mac2 are all forwarded to serdes_1, so that the data of mac1 and mac2 can only wait for at most 25G per second, even if more data packets need to be sent, and it can be understood that the applications called by mac1 and mac2 are relatively unimportant data here; the data sent by mac3 is all forwarded to SERDES_2, so that the data sent by mac3 can independently share 25G per second of traffic, namely, the application called by mac3 is important data and needs to exclusive certain bandwidth data; the data sent to mac4 is all forwarded to serdes_3 and serdes_4 so that mac4 can exclusively share 50G per second traffic, i.e., applications calling mac4 are also important and need to exclusive very large bandwidth data. The SERDES which is correspondingly sent by the specific source MAC can be set through the data flow control layer of hardware, so that a client can better adjust according to own service demands, the important service data can occupy sufficient bandwidth, the bandwidth is exclusively shared, and the timely and stable sending of the important service data is ensured.
In this embodiment, the number of configuration modules corresponds to the source MACs one by one, and each configuration module serves the corresponding source MAC. In this embodiment, there are a total of 4 configuration modules, i.e., configuration 1, configuration 2, configuration 3, and configuration 4, each of which is connected to a SERDES interface, i.e., each of which is connected to serdes_1, serdes_2, serdes_3, and serdes_4, respectively, so as to transmit data. In each configuration module, editing setting can be performed, configuration table information is written in, and the configuration table information is used for configuring data traffic to be forwarded to fixed SERDES, so that data traffic control can be realized. When the data on the mac1 corresponding to the CPU1 needs to be sent preferentially, a rule can be established in the configuration 1 of the data flow control layer, the data flow of the mac1 is forwarded to the SERDES1, if the data flow exceeds 25Gb/s, the rule can be modified, and the data flow of the mac1 is forwarded to the SERDES1 and the SERDES2, so that the data flow can reach the capacity of 50 Gb/s; if the importance of mac2 and mac3 data is not high, queuing can be performed, a rule can be established in configuration 2 of the data flow control layer, and data flows of mac2 and mac3 are forwarded to serdes_3, so that data of mac2 and mac3 share the bandwidth of serdes_3, whether the data flow is greater than 25Gb/s or not, the hardware is limited to 25Gb/s, and the excess data portions are queued for transmission in sequence.
Meanwhile, the configuration module at the data flow control layer can also be configured according to a time period, a preset time range of data flow control is set at the data flow control layer, and in the preset time range, the data of the source MAC is matched with corresponding SERDES interface transmission by the flow control layer; and not within the preset time range, setting all the SERDES interfaces to be shared by all the source MAC data of the MAC layer for transmission. For example, in the case of daytime traffic is relatively average, configuration 8 may be: 00 to 17:00 all source MACs share all SERDES, i.e. all traffic shares these 4 SERDES;17:00 to 24:00 when some sensitive services need to monopolize the data bandwidth, the flow control layer can be set to match the corresponding SERDES interface transmission for the data of the source MAC, namely, according to the configuration, a certain MAC is configured with a single SERDES for monopolizing the data bandwidth, so that the priority transmission of important data is ensured.
In this embodiment, the data of the multiple paths of CPUs are distributed from the hardware level according to the need, the data traffic of the service at the OS level is reasonably configured and forwarded, and the accurate control of the service traffic at the multi-host network card hardware level is realized, that is, the corresponding SERDES interface is allocated according to the traffic demand of the data of the upper layer service. The method ensures that the important business can independently share fixed physical bandwidth, and the data of the important business can be rapidly and even transmitted and received so as to realize that the important business can be timely transmitted under the condition of high traffic. Meanwhile, the method is simple and efficient in configuration and easy to operate, and can play a great role in a multihost application scene.
