Technical Field

The present application relates to the field of data processing, and more particularly, to a method and apparatus for data processing.

Background

The data packet aggregation is a method for combining a plurality of received data packets into a single data packet through a Network Interface Controller (NIC)/network card, and a processor or a service processing logic processes the aggregated data packet, which can reduce the service processing overhead for each data packet, thereby improving the service processing performance, efficiency, and throughput of the network end node.

Packet aggregation is reception-based aggregation that requires a first device (transmitting side) to slice data belonging to the same data stream according to a certain rule and a second device (receiving side) to aggregate received packets. A typical aggregation technique is that a first device performs data slicing on large TCP data through a TCP Segment Offload (TSO) technique, and a second device performs packet aggregation through a large packet aggregation (LRO) technique.

At present, an aggregation engine of a second device needs to know all details of a transmission protocol to implement data aggregation of the protocol, details of different transmission protocols are completely different, and even implementation details and requirements of the same transmission protocol on different operating systems or different platforms are different, so that the aggregation engine needs to perform a matching evolution packet header according to service evolution and support, and complexity and efficiency of aggregated data are high and low.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The data packet aggregation is a method for combining a plurality of received data packets into a single data packet through a Network Interface Controller (NIC)/network card, and a processor or a service processing logic processes the aggregated data packet, so that the service processing overhead of each data packet can be reduced, thereby improving the service processing performance, efficiency and throughput of the network end node.

The common NIC generates a CPU interrupt for a group of aggregated data packets, the CPU submits the group of aggregated data packets to the protocol stack for processing in an interrupt processing program, and finally the driver or the protocol stack releases the buffers occupied by the data packets together, thereby improving the processing efficiency of the service. The intelligent network card (Smart NIC) unloads the network processing protocol stack, and once service processing is performed on a group of aggregated data packets in the Smart NIC, so that the data processing efficiency can be improved, and the service performance can be improved.

When the aggregated packets arrive in sequence and belong to the same transmission message of the same stream, the efficiency of aggregation is significantly improved, for example, packets in a Transmission Control Protocol (TCP) stream are transmitted in a bit (byte) stream manner, allowing an application to transmit a packet in a RoCEv2 stream in a network protocol (RDMA over converted ethernet, roCE) for remote memory access via ethernet with a sequence number (sequence) and a message (message).

In this case, a group of aggregated packets may be presented to the processor as a single large packet, and the processor may complete the corresponding protocol stack related business processes in one operation. To achieve this, the aggregation processing engine should identify the following information in the received packet:

(1) Whether they belong to the same aggregate flow;

(2) Receiving new packets in the order required by the already aggregated packets:

(3) The newly received data packet belongs to the same message as the aggregated data packet.

As shown in fig. 1, a schematic diagram of slicing, transmitting, and aggregating processes by message is shown. The first equipment (the sending side) is sliced according to the message, the second equipment (the receiving side) is aggregated according to the message, and the intermediate network equipment transmits the data packets which are sliced into one piece.

Packet aggregation is reception-based aggregation that requires a first device to slice data belonging to the same data stream according to a certain rule and to aggregate received packets at a second device. A typical NIC technology is that a first device performs data slicing on large TCP data through a TCP Segment Offload (TSO) technology, and a second device performs packet aggregation through a large packet aggregation (LRO) technology. As shown in fig. 2, a schematic diagram of a TSO technique is shown; as shown in fig. 3, a schematic diagram of LRO technology is shown.

In the existing aggregation technology, user data transmitted through a network is encapsulated into different service layers of the data through messages, such as a transport layer (transport layer) and a placement layer (fastening layer). When the aggregation engine provides the merged data packet to the protocol stack, the key data information of different service layers should not be lost. Some data to be accumulated may be obtained from the last data packet, such as a sequence number; other parts of the data information need to perform "stateful" aggregation operations, such as Selective Acknowledgement (SACK) information of TCP.

Currently, aggregation engines are "stateless" processor engines that require guessing at the first device's intent to aggregate boundary definitions for packets. The aggregation engine of the second device needs to know all details of the transmission protocol to implement data aggregation of the protocol, the details of different transmission protocols are completely different, and even the implementation details and requirements of the same transmission protocol on different operating systems or different platforms are different, so that the aggregation engine needs to perform matching evolution according to service evolution and support. The aggregation engine can judge the aggregation qualification of the data packets to be merged according to heuristic analysis, deep packet header inspection and protocol perception capability, so that the complexity of aggregated data is high and the efficiency is low.

Therefore, the embodiment of the application provides a data processing method, which can reduce the complexity of aggregation processing data and improve the efficiency of aggregation processing.

As shown in fig. 4, a schematic view of an application scenario of the embodiment of the present application is shown. The first device and the second device both comprise intelligent network cards, and the intermediate network device can be a switch or a router.

As shown in fig. 5, a schematic flow chart interaction diagram of a method 500 for data processing proposed by the embodiment of the present application is shown. The method comprises the following steps:

the first device configures aggregation policy information for the data packet, where the aggregation policy information is used to indicate whether a second device receiving the data packet aggregates the data packet. Specifically, the first device may configure aggregation policy information for each of a plurality of data packets, where the plurality of data packets may be data packets belonging to different data flows, and the plurality of data packets may also be data packets belonging to the same data flow.

The plurality of data packets are obtained by slicing the data by the slicing engine in the first device according to the message. The slicing engine may be a hardware module or a software module.

Optionally, the header of the data packet includes aggregation policy information, where the aggregation policy information may include at least one of the following information: sequence number of the packet, boundary information, priority information, dirty field, dirty mode field, etc. Wherein the boundary information is used for indicating a way of not aggregating the data packets or aggregating the data packets; the priority information is used for indicating the priority of the data packet; the dirty field is used to indicate whether data in a data packet is modified by a third device, wherein the third device is a device used to transmit the data packet; the dirty mode field is used to indicate whether to ignore the dirty field. It should be appreciated that only the dirty field may be modified by the third device transmitting the data packet, and other information in the aggregated policy information may not be modified by the third device. Illustratively, the boundary information may include any one of: first boundary information, second boundary information, third boundary information, or fourth boundary information. The first boundary information is used for indicating that the data packet is not aggregated, and it can be understood that the data packet can be sent to the processor for processing; the second boundary information is used for indicating that the data packet can be aggregated with the data packet sent after the data packet, namely the data packet cannot be aggregated with the data packet sent before the data packet; the third boundary information is used to indicate that the data packet may be aggregated with the data packet sent before the data packet and the data packet sent after the data packet, it is understood that the data packet may be aggregated with not only the data packet sent before the data packet but also the data packet sent after the data packet; the fourth boundary information is used to indicate that the data packet cannot be aggregated with a data packet sent after the data packet, and the data packet may be aggregated with a data packet sent before the data packet, or may not be aggregated with the data packet.

It should be understood that the data packet may be understood as a data packet, and the header of the data packet may be understood as a header of the data packet, which is not specifically limited in this application.

Optionally, the boundary information is indicated by bit (bit) information. When the bit information is equal to the first value, indicating that the boundary information in the data packet is first boundary information; when the bit information is equal to a second value, indicating that the boundary information in the data packet is second boundary information; when the bit information is equal to a third value, indicating that the boundary information in the data packet is third boundary information; when the bit information is equal to the fourth value, indicating that the boundary information in the data packet is fourth boundary information. Illustratively, when the bit information for indicating the boundary information in the packet is equal to the first value, "locator" may be indicated, indicating that the packet is a separate packet; when the bit information for indicating the boundary information in the data packet is equal to the second value, "first" may be indicated, indicating that the data packet is the first data packet in the data stream; when the bit information for indicating the boundary information in the data packet is equal to the third value, "next" may be indicated, indicating that the data packet is an intermediate data packet in the data stream; when the bit information indicating the boundary information in the packet is equal to the fourth value, "last" may be indicated, indicating that the packet is the last packet in the data stream. Illustratively, the bit information may occupy two bits in the header of the data packet. The first value may be equal to 0, the second value may be equal to 1, the third value may be equal to 2, and the fourth value may be equal to 3.

Illustratively, the sequence number of the data packet may be monotonically increasing or may be monotonically decreasing. The first device may assign a unique sequence number to each packet, where the sequence number of the initially transmitted packet is different from the sequence number of the retransmitted packet. In addition, the serial number with the bit width of 40 bits/48 bits/64 bits can be adopted in the embodiment of the application, so that the turnover period of the serial number is increased, and the turnover of the serial number is reduced.

Illustratively, the priority information includes first priority information or second priority information, the first priority information may indicate that the priority of the data packet is high priority, for example, the first priority information may indicate that the priority of the data packet is higher than or equal to a preset value, the second priority information may indicate that the priority of the data packet is low priority, for example, the second priority information may indicate that the priority of the data packet is lower than the preset value, which may be predefined. When the priority of the data packet is high, it indicates that the data packet is not negligible or important, and needs to be indicated to the processor for processing.

Alternatively, the priority information may be indicated by bit information. Illustratively, the bit information may occupy one bit in the header of the data packet. When the bit value corresponding to the bit is equal to 1, it may indicate that the priority of the data packet is higher than or equal to a preset value; when the bit value corresponding to the bit is equal to 0, it may indicate that the priority of the data packet is lower than a preset value. For example, when the bit value for indicating the priority of the data packet is equal to 1, an "on" may be indicated, indicating that the data packet needs to be individually indicated to the processor for processing; when the bit value indicating the priority of the packet is equal to "0", it may indicate "off", indicating that the packet does not need to be separately indicated to the processor for processing.

Alternatively, the dirty field and the dirty mode field may also be indicated by bit information.

And 520, the first device sequentially sends data packets to the second device, wherein the data packets comprise aggregation strategy information.

In particular, the first device may send a plurality of data packets to the second device through the at least one third device. The second device may be an aggregation engine. The third device, which may be a switch or a router, etc., may also be referred to as an intermediate device.

And 530, the second device receives a data packet sent by the first device, wherein the data packet comprises aggregation policy information, and the aggregation policy information is used for indicating whether to aggregate and process the data packet.

In particular, the second device may receive a plurality of data packets transmitted by the first device through the at least one third device.

The dirty field in the aggregation policy information is modifiable by a third device (intermediate device) that transmitted the packet. The dirty field may occupy one bit in the header of the data packet. Specifically, when the dirty field in the data packet is the first indication value, the dirty field is used to indicate that the data in the data packet is modified by the third device, in this case, the modified data packet cannot be aggregated with other data packets; when the dirty field in the data packet is the second indication value, the dirty field is used to indicate that the data in the data packet has not been modified by the third device. The third device modifies the data in the data packet, including adding the address information of the third device to the data packet, so that the second device can know the transmission path of the data packet. For example, the first indication value may be "1" and the second indication value may be "0".

For example, the first device configures a bit value in a dirty field to be 0, if data in a data packet is modified, the bit value in the dirty field is modified to be 1 (a first indication value), and the modified dirty field indicates that the data packet cannot be aggregated with other data packets. If the data in the data packet is not modified, the bit value in the dirty field is not modified and remains 0 (second indicator value). It should be understood that the first device configures the bit value in the dirty field to be 1, which is not particularly limited. In addition, a dirty field may occupy more bits.

The dirty mode field is used to indicate whether to ignore the dirty field, which is to be understood as indicating whether to ignore the bit value in the dirty field as modified. The dirty mode field may occupy two bits in the header of the data packet. Illustratively, when the bit value in the dirty mode field in the data packet is 0, it may indicate to ignore the dirty field; when the bit value in the dirty mode field in the data packet is 1, it may indicate that the dirty field is not to be ignored. It should be understood that, when the bit value in the dirty mode field in the data packet indicates 1, it may indicate to ignore the dirty field, which is not specifically limited in this application.

The second device processes the packet according to the aggregation policy information in the packet 540. Specifically, the aggregation engine in the second device processes the data packet according to the aggregation policy information in the data packet. The aggregation engine may be a hardware module or a software module.

Illustratively, the aggregation policy information may include a sequence number of the data packet and one of the following four types of boundary information: first boundary information, second boundary information, third boundary information, or fourth boundary information.

When the aggregation policy information of the data packet includes the first boundary information, the second device does not aggregate the data packet, and may send the data packet to the processor separately for processing. The processor may be a processor in a protocol stack of the host independent from the second device, or may be a processor in the second device, which is not particularly limited.

When the second boundary information is included in the aggregation policy information of the data packet, the second device may aggregate the data packet with a data packet received after the data packet, but the data packet cannot be aggregated with a data packet transmitted before the data packet. For example, the aggregation policy information of the packet with sequence number 101 includes second boundary information, and if the second device receives the packet with sequence number 102 after receiving the packet with sequence number 101, the second device may aggregate the packet with sequence number 101 and the packet with sequence number 102; if the second device receives the data packet with the sequence number of 103 instead of the data packet with the sequence number of 102 after receiving the data packet with the sequence number of 101, the second device does not need to aggregate the data packet with the sequence number of 101 and the data packet with the sequence number of 103, and only needs to send the data packet with the sequence number of 101 to the processor separately. The packet with sequence number 101, the packet with sequence number 102, and the packet with sequence number 103 belong to the same flow and the same message.

When the third boundary information is included in the aggregation policy information of the data packet, the second device may aggregate the data packet with not only a data packet received before the data packet but also a data packet received after the data packet. For example, the aggregation policy information of the packet with sequence number 202 includes third boundary information, and if the second device receives a packet with sequence number 201 before receiving the packet with sequence number 202, the second device may aggregate the packet with sequence number 202 and the packet with sequence number 201; if the second device receives a packet with sequence number 203 after receiving a packet with sequence number 202, the second device may aggregate the packet with sequence number 203 with the packet with sequence number 201 and the packet with sequence number 202. The packet with sequence number 201, the packet with sequence number 202, and the packet with sequence number 203 belong to the same flow and the same message.

When the fourth boundary information is included in the aggregation policy information of the data packet, the second device may or may not aggregate the data packet with the data packet transmitted before the data packet, but the data packet cannot be aggregated with the data packet transmitted after the data packet. For example, the aggregation policy information of the packet with the sequence number 302 includes fourth boundary information, and if the second device receives a packet with the sequence number 301 before receiving the packet with the sequence number 302, the second device may aggregate the packet with the sequence number 302 and the packet with the sequence number 301. If the second device does not receive the packet with sequence number 301 before receiving the packet with sequence number 302, the second device may send the packet with sequence number 302 to the processor separately. The data packet with sequence number 301 and the data packet with sequence number 302 belong to the same data flow and the same message.

Illustratively, the aggregation policy information may include a sequence number, boundary information, and priority information of the data packet.

When the aggregation policy information of the data packet includes the first priority information and the third boundary information, the second device may aggregate the data packet with a data packet received before the data packet and a data packet received after the data packet, and the aggregation context information sent by the second device to the processor includes identification information of the data packet, which is used to instruct the processor to process the data packet. The identification information of the data packet may be header information of the data packet, or may be a serial number of the data packet, which is not specifically limited in this application.

It should be understood that the aggregated context information includes header information of a first (first) data packet, header information of a last (last) data packet, and data information of the aggregated data packets. Therefore, when the boundary information in the aggregation policy information of the data packet is the first boundary information, the second boundary information, or the fourth boundary information, the header information of the data packet is sent to the processor through the aggregation context information, and it is not necessary to indicate that the priority of the data packet is higher than or equal to the preset value through the first priority information, that is, it is not necessary to add the header information of the data packet or the sequence number of the data packet again in the aggregation context information sent by the second device to the processor.

Optionally, when the aggregation policy information of the data packet includes the first priority information and the third boundary information, the second device may also aggregate the data packet with a data packet received before the data packet, or the second device aggregates the data packet with a data packet received after the data packet, so that the aggregation context information sent by the second device to the processor includes the header information of the data packet.

Optionally, when the aggregation policy information includes the second priority information and the boundary information, the second device may process the data packet according to the boundary information, which may be understood as that the second device processes the data packet according to the sequence number and the boundary information of the data packet, and the specific process is as described above.

Illustratively, the aggregation policy information may include a sequence number, boundary information, priority information, and a dirty field of the packet.

When the dirty field is included in the aggregation policy information of the data packet and indicates that the data packet is modified by the third device, the second device does not aggregate the data packet. It should be appreciated that when the dirty field indicates that the packet is modified by the third device, the second device cannot aggregate the packet regardless of which boundary information the boundary information in the aggregation policy information is, and regardless of whether the priority information in the aggregation policy information is the first priority information or the second priority information.

When the dirty field is included in the aggregation policy information of the data packet and indicates that the data packet is not modified by the third device, the second device processes the data packet according to at least one of the sequence number, the boundary information and the priority information of the data packet.

For example, in the case where only the sequence number, the boundary information, and the dirty field of the data packet are included in the aggregation policy information, when the dirty field indicates that the data packet is not modified by the third device, the second device may process the data packet according to the sequence number and the boundary information of the data packet. When the aggregation policy information includes the sequence number, the boundary information, the priority information, and the dirty field of the data packet, the second device may process the data packet according to the sequence number, the boundary information, and the priority information of the data packet when the dirty field indicates that the data packet is not modified by the third device.

Illustratively, the aggregation policy information may include a sequence number, boundary information, priority information, a dirty field, and a dirty mode field of the packet.

When the dirty field in the aggregation policy information indicates that the data packet is modified by the third device and the dirty mode field indicates that the dirty field is not to be ignored, the second device does not aggregate the data packet. It should be appreciated that when the dirty field indicates that the data packet is modified by the third device and the dirty mode field indicates that the dirty field is not to be ignored, the second device cannot aggregate the data packet regardless of which boundary information the boundary information in the aggregation policy information is, and regardless of whether the priority information in the aggregation policy information is the first priority information or the second priority information.

When a dirty field in the aggregation policy information indicates that the packet is modified by the third device, but the dirty mode field indicates that the dirty field is ignored, the second device may process the packet according to at least one of sequence number, boundary information, and priority information of the packet. For example, in a case where only the sequence number, the boundary information, the dirty field, and the dirty mode field of the data packet are included in the aggregation policy information, when the dirty field indicates that the data packet is modified by the third device and the dirty mode field indicates that the dirty field is ignored, the second device may process the data packet according to the sequence number and the boundary information of the data packet. In a case where the aggregation policy information includes a sequence number, boundary information, priority information, a dirty field, and a dirty mode field of the packet, when the dirty field indicates that the packet is modified by the third device and the dirty mode field indicates that the dirty field is ignored, the second device may process the packet according to the sequence number, boundary information, and priority information of the packet.

When the dirty field in the aggregation policy information indicates that the data packet is not modified by the third device, the second device may process the data packet according to at least one of sequence number, boundary information, and priority information of the data packet, regardless of whether the dirty mode field indicates to ignore the dirty field or indicates not to ignore the dirty field. For example, in a case where only the sequence number, the boundary information, the dirty field, and the dirty mode field of the data packet are included in the aggregation policy information, when the dirty field indicates that the data packet is not modified by the third device, the second device may process the data packet according to the sequence number and the boundary information of the data packet. In a case where the aggregation policy information includes a sequence number, boundary information, priority information, a dirty field, and a dirty mode field of the data packet, when the dirty field indicates that the data packet is not modified by the third device, the second device may process the data packet according to the sequence number, boundary information, and priority information of the data packet.

Fig. 6 shows a schematic diagram of the location of aggregation policy information in the header of a data packet. The data packet may include information such as a sequence number, boundary information, priority information, a dirty field, a dirty mode field, and user data of the data packet, where the boundary information, the priority information, the dirty field, and the dirty mode field may occupy 6 bits in a header of the data packet. A field composed of the boundary information, the priority information, the dirty field, and the dirty mode field may be referred to as an aggregation tag (aggregation tag), a field composed of the sequence number of the packet, the boundary information, the priority information, the dirty field, and the dirty mode field may be referred to as an aggregation header (aggregation header), and the aggregation header may be understood as the aggregation policy information. It should be appreciated that the present application is not limited to the particular location in the header of the data packet where the aggregate tag and the serial number of the data packet should be placed.

In the technical solution provided in the embodiment of the present application, a data packet sent by a first device includes aggregation policy information used for indicating whether a second device receiving the data packet performs aggregation processing on the data packet, and the second device may process the data packet according to the aggregation policy information in the received data packet. The first device indicates whether or how to aggregate the data packets by configuring the aggregation policy information in the data packets, and the second device does not need to guess the intention of the first device and implement the aggregation processing of the data packets according to all details of the transmission protocol, so that the complexity of the aggregation processing of the data by the second device can be reduced, and the efficiency of the aggregation processing can be improved.
