Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data transmission, and particularly relates to a TCP message encapsulation method and device, electronic equipment and a storage medium. BACKGROUND

[0002] TCP (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer protocol. TCP can ensure the integrity and accuracy of data through its own series of characteristics. TCP is widely used in network communication that requires reliability, but these characteristics of TCP also bring additional performance overhead and complexity, which limits its real-time communication and high-efficiency transmission. For example, TCP needs to perform three-way handshake when connecting and four-way handshake when disconnecting. Although this constraint ensures the stability of data transmission, it greatly reduces the speed of real-time communication.

[0003] In the prior art, TSO (TCP Segment Offload) technology is generally used to dynamically adjust the size of the data packet to adapt to the MTU (Maximum Transmission Unit) of different network segments, reduce the performance loss caused by IP (Internet Protocol) layer fragmentation, reduce delay, and improve the overall performance of network communication.

[0004] However, when segmenting and offloading TCP data packets, the IP header and the complete TCP header are saved. As shown in Figure 1 , a complete TCP data packet is segmented into multiple smaller segment messages according to the MSS (Maximum Segment Size). The TCP frame header of each segment message is as shown in Figure 2 . The TCP frame header shown in Figure 2 is retransmitted when each segment message is sent, which greatly reduces the data transmission rate. SUMMARY

[0043] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0044] In order to solve the problem of low transmission rate of data in the prior art, the present application provides a TCP message encapsulation method, Figure 3 is a flowchart of the TCP message encapsulation method provided by the present application, as shown in Figure 3 The TCP message encapsulation method comprises the following steps 310 to 330.

[0045] Step 310, receiving a TCP message sent by a CPU in the local end, and segmenting the TCP message into at least two first segmented messages in the case that a communication connection is established between the opposite end and the local end.

[0046] Specifically, after receiving the TCP message sent by the CPU in the local end and the communication connection is established between the opposite end and the local end, if the TCP message exceeds the MTU (Maximum Transmission Unit) of the network segment, the electronic device can segment the TCP message by the MSS (Maximum Segment Size) negotiated in the communication process between the opposite end and the local end to obtain at least two first segmented messages. The MSS can be understood as the most suitable data block size in the data transmission process. The segmentation can better adapt to the network environment, reduce the load of the transmission of the single first segmented message, improve the network throughput, and realize the reliable transmission of data.

[0047] It should be noted that the TCP message encapsulation method provided by the present application is applied to an electronic device in the local end. The electronic device can comprise a network interface card or other hardware devices, and the electronic device is in communication connection with the CPU in the local end. The local end can be a client or a server. When the local end is a client, the opposite end is a server, and vice versa, when the local end is a server, the opposite end is a client.

[0048] Figure 4 is a flowchart of data transmission provided by the present application, as shown in Figure 4 Before the TCP message is segmented in the local end, the data transmission comprises the following steps.

[0049] S1, the application layer issues an instruction, the CPU in the local end executes the application program to issue an instruction, and prepares to send data.

[0050] S2, the to-be-sent data is delivered to the transport layer after being encapsulated by the presentation layer and the session layer, and the transport layer encapsulates the to-be-sent data by TCP (Transmission Control Protocol), adds necessary TCP header information to the to-be-sent data, and the TCP header information can include: source port number, destination port number, sequence number and length information. Then the to-be-sent data with the added TCP header information is transmitted to the network layer.

[0051] S3, the network layer adds IP (Internet Protocol) header information to the TCP header information of the to-be-sent data delivered, to form a TCP message. The IP header information can include: source IP address and destination IP address information. Then the network layer delivers the TCP message to the link layer. In the link layer, the electronic device adds a MAC (Media Access Control Address) frame header to the IP header information of the delivered TCP message, and the MAC frame header can include source MAC address, destination MAC address, type field and CRC (Cyclic Redundancy Check) field information. Then the TCP message with the added MAC frame header is delivered to the physical layer and communicates with the opposite end on the Ethernet medium.

[0052] S4, the communication connection between the local end and the opposite end is established by the "three-way handshake" in TCP. During the "three-way handshake", the opposite end and the local end will negotiate some communication parameters, which at least include part of the fields in the redundancy field and the MSS. The three-way handshake actually provides a parameter basis for subsequent data segmentation.

[0053] Step 320, optimizing the redundancy field in each of the first segment messages to determine each first encapsulated message.

[0054] Specifically, since the redundancy fields in each of the first segment messages are the same, by optimizing the redundancy fields in each of the first segment messages, each first encapsulated message is obtained, and by reducing the header overhead in each of the first segment messages, the repeated transmission of the redundancy field is avoided.

[0055] Further, the redundancy field includes a source port and a destination port.

[0056] The optimization of the redundancy field in each of the first segment messages to determine each first encapsulated message includes:

[0057] obtaining the source port and the destination port confirmed by the opposite end and the local end during the communication process;

[0058] For each first segmented packet, the source port and the destination port in the TCP frame header of the first segmented packet are deleted to determine a second segmented packet; the first encapsulated packet is determined based on a segment type corresponding to the second segmented packet, wherein the segment type is used to represent a position of the second segmented packet in the TCP packet.

[0059] Specifically, since the source port and the destination port of the peer and the local end are obtained during the "three-way handshake", to avoid repeated transmission of the source port and the destination port, the source port and the destination port in the TCP frame header of each first segmented packet can be deleted to obtain the second segmented packet with the optimized TCP frame header. Then, according to the segment type of each second segmented packet, i.e., according to the position of each second segmented packet in the TCP packet, the TCP frame header of each second segmented packet is further optimized to obtain each first encapsulated packet.

[0060] Further, the redundant field further includes an acknowledgement number.

[0061] The first encapsulated packet is determined based on a segment type corresponding to the second segmented packet, and the segment type is used to represent a position of the second segmented packet in the TCP packet.

[0062] In a case where the segment type corresponding to the second segmented packet is a first segment packet, the second segmented packet is determined as the first encapsulated packet.

[0063] In a case where the segment type corresponding to the second segmented packet is a non-first segment packet, the acknowledgement number in the TCP frame header of the second segmented packet is deleted to obtain the first encapsulated packet.

[0064] Specifically, since each second segmented packet belongs to the same TCP packet, the acknowledgement numbers of the second segmented packets are the same, which can be the response to the previous request. Therefore, for each second segmented packet, if the second segmented packet is a first segment packet of the TCP packet, the acknowledgement number in the TCP frame header of the first segment packet can be retained, i.e., the second segmented packet is directly determined as the first encapsulated packet. If the second segmented packet is a non-first segment packet of the TCP packet, the acknowledgement number in the TCP frame header of the non-first segment packet can be deleted, and the acknowledgement number of the first segment packet is shared, so that the same acknowledgement number does not need to be repeatedly sent in the transmission process of each non-first segment packet.

[0065] For example, as shown in the TCP frame header, Figure 2 After the source port, the destination port and the acknowledgement number are deleted, the TCP frame header can be optimized from a fixed 20 bytes to 12 bytes, reducing the overhead of the TCP frame header by 40%.

[0066] Step 330, for each first encapsulation packet, determining a second encapsulation packet corresponding to the first encapsulation packet based on the corresponding check state data of the local end; the check state data is used to indicate whether the first encapsulation packet enables check and offloading.

[0067] Specifically, after determining each first encapsulation packet, the check state data configured in the local end can be determined, and through the check state data, it can be determined whether the check and offloading is supported in the local end. Through the check state data, the TCP frame header of each first encapsulation packet can be further optimized to obtain the second encapsulation packet of the optimized user.

[0068] It should be noted that the check and offloading is an effective technology to improve network performance, which transfers the check and calculation and verification tasks of the data packet from the CPU to the electronic device, uses hardware acceleration to quickly complete the generation and verification of the check sum, reduces the delay in the data transmission process, effectively reduces the burden of the CPU, and improves the communication efficiency of the network.

[0069] Further, the determination of the second encapsulation packet corresponding to the first encapsulation packet based on the corresponding check state data of the local end comprises:

[0070] In the case that the check state data indicates that the local end enables check and offloading, the check sum corresponding to the first encapsulation packet is determined, and the TCP frame header of the first encapsulation packet is updated based on the check sum to obtain the second encapsulation packet;

[0071] In the case that the check state data indicates that the local end does not enable check and offloading, the first encapsulation packet is determined as the second encapsulation packet.

[0072] Specifically, if it is determined according to the check state data that the local end supports check and offloading, the electronic device calculates the check sum of the first encapsulation packet and verifies it, and inserts the value of the check sum into the check sum field in the TCP frame header of the first encapsulation packet to obtain the second encapsulation packet after optimization. If it is determined according to the check state data that the local end does not support check and offloading, the first encapsulation packet does not need to be further optimized, and the first encapsulation packet can be directly determined as the second encapsulation packet.

[0073] Further, the determination of the check sum corresponding to the first encapsulation packet comprises:

[0074] Based on the pseudo header corresponding to the first encapsulation packet, the check sum corresponding to the first encapsulation packet is determined.

[0075] Specifically, if checksum offload is supported at the local end, a pseudo header corresponding to each first encapsulated packet can be obtained, the pseudo header can include a source IP address, a destination IP address, a padding field, a protocol number, and a TCP packet length, etc. Each first encapsulated packet belongs to the same TCP packet, and thus the pseudo headers of the first encapsulated packets are the same. After determining the pseudo headers of the first encapsulated packets, the checksum of each first encapsulated packet can be calculated according to the pseudo header.

[0076] For example, Figure 5 is a schematic diagram of a TCP frame header enabling checksum offload provided by an embodiment of the present application, Figure 6 is a schematic diagram of a second encapsulated packet enabling checksum offload provided by an embodiment of the present application. If checksum offload is enabled at the local end, a redundant field is deleted, and a TCP frame header of the second encapsulated packet after insertion of the checksum is as shown in Figure 5 , and a complete second encapsulated packet is as shown in Figure 6 . In the figures, EH represents an Ethernet frame header, IPH represents an IP frame header, CRC represents an Ethernet checksum, TPi represents the i-th segment of TCP payload segment data, the TCP payload segment data of all second encapsulated packets can constitute TCP payload data of a TCP packet, i is a positive integer less than n, n represents the number of all second encapsulated packets, and THLC represents a TCP frame header enabling checksum offload.

[0077] In addition, if checksum offload is not enabled at the local end, the TCP frame header of the second encapsulated packet is different from the TCP frame header as shown in Figure 5 , in that the checksum field is empty. Figure 7 is a schematic diagram of a second encapsulated packet without enabling checksum offload provided by an embodiment of the present application, and a complete second encapsulated packet obtained is as shown in Figure 7 , in which THL represents a TCP frame header without enabling checksum offload.

[0078] It should be noted that the checksum is used to detect whether an error occurs in each first encapsulated packet during transmission, and the checksum is determined based on the pseudo header and the TCP payload data. Therefore, although the pseudo headers of the first encapsulated packets are the same, the TCP payload data in the first encapsulated packets are different, and thus the values of the checksums of the first encapsulated packets calculated are different.

[0079] Further, the method further includes:

[0080] According to the segment order of each second encapsulated packet, each second encapsulated packet is sequentially sent to the opposite end.

[0081] Specifically, after determining each second encapsulated packet, the electronic device can sequentially send each second encapsulated packet to the opposite end according to the segment order of each second encapsulated packet, to realize network communication between the local end and the opposite end.

[0082] The TCP packet encapsulation method provided in this embodiment of the invention segments the TCP packets sent by the local CPU to obtain at least two first segment packets. When a communication connection is established between the local and the remote end, redundant fields in each first segment packet are optimized to obtain an optimized first encapsulated packet. At the same time, based on the verification status data configured on the local end to enable or disable verification and offloading, the encapsulation method of each first encapsulated packet is optimized to obtain an optimized second encapsulated packet. This reduces the header overhead in each second encapsulated packet, avoids the repeated transmission of redundant fields, and thus improves the real-time data transmission efficiency.
