The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
The invention provides a message processing method, network equipment and storage medium under a 5G network, wherein the message processing method under the 5G network is applied to a first processing unit of the network equipment, the network equipment comprises the first processing unit and a second processing unit, and the second processing unit is connected with the first processing unit. Acquiring an original data message, wherein the original data message comprises a first packet header field and a first data field; under the condition that the length of the original data message exceeds a preset first threshold value, a plurality of second fields are obtained according to the first threshold value, the first packet header field and the first data field; adding a second packet header in front of each second field to form a plurality of sub-data messages corresponding to the original data messages, wherein the second packet header is used for representing the corresponding relation between the sub-data messages and the original data messages; and sending each sub-data message to the second processing unit. According to the embodiment of the invention, under the condition that the length of the original data message exceeds the preset first threshold, a plurality of second fields are obtained according to the first threshold, the first packet header field and the first data field; the original data message which is received by the second processing unit and has a longer length can be split into a plurality of second fields, a second packet head is added in front of each second field to form a plurality of sub-data messages corresponding to the original data message, and each sub-data message is sent to the second processing unit; the second processing unit can restore the original data message according to the corresponding relation between the sub-data message represented by the second packet header and the original data message, so that the length of the data message received by the second processing unit can be reduced, the memory which is required to be pre-allocated by the second processing unit for receiving the data message is reduced, and the problem that in the prior art, the memory resource waste is caused by the fact that the buffer memory for pre-storing the received message is large in the 5G UPF can be solved.
Embodiments of the present invention will be further described below with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is a schematic diagram of a UPF device 100 according to an embodiment of the present invention, in the example of fig. 1, the UPF device 100 includes a first processing unit 101 and a plurality of second processing units 102, where the second processing units 102 are respectively connected to the first processing unit 101, and the first processing unit 101 is provided with an external network port for communicating with the outside, and an internal network port for communicating with the second processing unit 102.
Specifically, after receiving a message from the network card, the CPU of the UPF device stores the message in a memory applied in advance, then applies a new memory to replace the memory just received, and uploads the memory buffer descriptor storing the data to the operating system kernel. The receiving process is asynchronous to the CPU, so that the receiving buffer address is firstly set on the network port hardware, and when the network port receives the message, the data is filled into the preset buffer through a direct memory operation mode. For 5G UPF, the network port bandwidth can reach 10Gbps, so that only one receiving BD cannot be set for buffering received data, otherwise packet loss is easily caused. However, the number of received BDs of the portal of the 5G UPF is several thousands or even tens of thousands, and the buffer length of one BD is generally set to 1518 bytes. Therefore, in the related art, the buffer memory of the network port for pre-storing the received message is also large. Even if no message is input, the reserved buffer space can not be moved to other uses, so that the waste of memory resources is caused. For 5G UPF other than X86, the memory may not have tens of GB, and may be 1G to 8GB. Memory is a valuable hardware resource of a computer system, almost all computing uses memory as a storage medium, and if the memory consumption is too high, new services may not be performed because the memory is not applied.
In a specific example, the UPF device includes a main control board MPU, a main control board, i.e., a first processing unit; the UPF device further includes two service boards, namely an SPU1 and an SPU2, respectively, and the service boards are also referred to as a second processing unit. The main control board is provided with 3 network ports, namely eth0, eth1 and eth2, wherein eth1 and eth2 are opposite-internal network ports, and eth1 and eth2 are in single-board butt joint with SPU1 and SPU2 respectively. On the single board of the MPU, the receiving buffer lengths of eth1 and eth2 are set to 512 bytes, and the receiving buffers of the network ports eth0 of the SPU1 and SPU2 are also set to 512 bytes, so that compared with the scheme of receiving the BD with the length preset to 1518 bytes in the related art, at least 20 Mbyte memory is saved.
Specifically, referring to fig. 2, fig. 2 is a schematic diagram of an internal network port provided by a specific example of the present invention, a network port of an external network on a UPF device is in butt joint with an external device, a message length is long or short, and a receiving BD length is preset to 1518 bytes. However, the internal network ports of the UPF are also in butt joint with the software and hardware system board of the manufacturer, so in the example of fig. 2, the buffer length of the received messages of the network ports can be set to 512 bytes, and then two thirds of the memory can be saved by one internal network port.
The UPF device and the application scenario described in the embodiments of the present invention are for more clearly describing the technical solution of the embodiments of the present invention, and do not constitute a limitation on the technical solution provided by the embodiments of the present invention, and those skilled in the art can know that, with the evolution of the communication technology and the appearance of the new application scenario, the technical solution provided by the embodiments of the present invention is applicable to similar technical problems.
It will be appreciated by those skilled in the art that the UPF device illustrated in FIG. 1 is not limiting of embodiments of the present invention and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.

step S400, each sub data message is sent to the second processing unit.
According to the scheme provided by the embodiment of the invention, under the condition that the length of the original data message exceeds a preset first threshold value, a plurality of second fields are obtained according to the first threshold value, the first packet header field and the first data field; the original data message which is received by the second processing unit and has a longer length can be split into a plurality of second fields, a second packet head is added in front of each second field to form a plurality of sub-data messages corresponding to the original data message, and each sub-data message is sent to the second processing unit; the second processing unit can restore the original data message according to the corresponding relation between the sub-data message represented by the second packet header and the original data message, so that the length of the data message received by the second processing unit can be reduced, the memory which is required to be pre-allocated by the second processing unit for receiving the data message is reduced, and the problem that in the prior art, the memory resource waste is caused by the fact that the buffer memory for pre-storing the received message is large in the 5G UPF can be solved.
Specifically, as shown in fig. 4, fig. 4 is a schematic structural diagram of an original DATA packet provided in an embodiment of the present invention, where in the example of fig. 4, the original DATA packet includes a mac_dst field, a mac_src field, a TYPE field, and a DATA field, where the mac_dst field, the mac_src field, and the TYPE field are first header fields, and the DATA field is a first DATA field.
Specifically, the mac_dst field and the mac_src field are used to represent the MAC address of the reception source and the MAC address of the transmission direction, respectively.
Specifically, the length of the mac_dst field and the mac_src field are both 6 bytes, and the length of the TYPE field is 2 bytes, that is, the total length of the first packet header field is 14 bytes.
As shown in fig. 5, the above method step S200 includes, but is not limited to, step S210 and step S220:
Step S210, subtracting the length of the second packet header from the first threshold to obtain a second threshold under the condition that the length of the original data message exceeds the first threshold;
Step S220, splitting the original data message into a plurality of continuous second fields, wherein the first second field comprises a first packet header field and a first data field, the length of each second field does not exceed a second threshold value, and the length of each second field is less than one second field of the second threshold value.
Specifically, the second fields are split from the original data message in sequence, so that the first second fields comprise the first packet header field and the first data field at the same time, and the original data message can be restored by sequentially combining the second fields in sequence.
In an embodiment, the second header includes a first flag field and a second flag field, where the first flag field of each sub-data packet corresponding to the same original data packet is the same, and the second flag field is used for the second processing unit to restore the original data packet according to each sub-data packet in sequence.
As shown in fig. 6, the above-mentioned method step S300 includes, but is not limited to, step S310, step S320, step S330, and step S340:
Step S310, generating a first mark field according to the original data message, wherein the first mark fields of all sub data messages corresponding to the same original data message are the same;
Step S320, generating second mark fields corresponding to the sub data messages one by one according to the generation sequence of the sub data messages, wherein the second mark fields are used for a second processing unit to restore original data messages according to the sub data messages in sequence;
step S330, a second packet header corresponding to the second fields one by one is generated according to the first mark field and the second mark field, and the second packet header is combined with the corresponding second fields to obtain the sub-data message.
As shown in fig. 7, fig. 7 is a schematic structural diagram of a first sub data packet obtained from the original data packet in fig. 4, and the sub data packet shown in fig. 7 is generated in the case that the first threshold is defined as 512 bytes in the original data packet in fig. 4, and in the example in fig. 7, a second header of the sub data packet includes a mac_dst field, a mac_src field, a type identification field, and a sequence identification field sequentially from front to back.
Specifically, the length of the type identifier field is 2 bytes, the content is 0x9999, and when the second processing unit detects that the thirteenth to fourteenth bytes of the packet header of the received packet are 0x9999, the packet header of the received packet can be confirmed to be a sub-data packet.
Specifically, the length of the sequence identifier field is 2 bytes, and since fig. 6 is a schematic structural diagram of the first sub-data packet obtained according to the original data packet in fig. 4, the sequence identifier field is 0x0000, and similarly, the sequence identifier field of the second sub-data packet obtained according to the original data packet in fig. 4 is 0x0001.
Specifically, the first tag field and the second tag field include a sequence identification field.
Specifically, since the first threshold is 512 bytes, in the example of fig. 6, the length of the second field is 496 bytes, that is, the second field includes 496 field contents of the original data packet from front to back in fig. 4.
As shown in fig. 8, fig. 8 is a schematic diagram of a structure of a second sub-data packet obtained according to the original data packet in fig. 4, where the second sub-data packet obtained according to the original data packet in fig. 4 is different from the first sub-data packet obtained according to the original data packet in fig. 4 only in sequence identification field, and the sequence identification field of the second sub-data packet is 0x0001, so that whether a plurality of sub-data packets correspond to the same original data packet can be obtained by verifying whether the mac_dst field, the mac_src field and the type identification field of the sub-data packet header are consistent, after the result of the verification, the sequence of each sub-data packet can be determined by the sequence identification field, and then the second fields of each sub-data packet can be combined in sequence to restore the original data packet.
In an embodiment, the method step further includes step S500: and under the condition that the length of the original data message does not exceed the first threshold value, sending the original data message to the second processing unit.
If the length of the original data message does not exceed the first threshold value, the original data message is not required to be split into a plurality of sub data messages, and the sub data messages are directly sent to the second processing unit.
As shown in fig. 9, fig. 9 is a flowchart of a method for processing a message under a 5G network according to another embodiment of the present invention, and in the example of fig. 9, the method for processing a message under a 5G network according to the embodiment of the present invention is applied to a second processing unit, which includes, but is not limited to, step S600, step S700, and step S800;

Specifically, the above method step further includes step S500: and under the condition that the received data message is a sub data message and the first memory space does not exist, applying the first memory space to the second processing unit according to a preset memory space value, wherein the first memory space is used for restoring the sub data message into an original data message.
Specifically, the static variable pBuf is defined for applying 1600 bytes of memory, i.e., applying for 1600 bytes of first memory space, whose initial value is NULL. The memory is actually applied when the first 0x9999 type message is encountered.
Specifically, the first threshold is set to 512 bytes, and the length of the second header is 16 bytes.

step S831, the length of the message in the first memory space is used as the current message length;
in step S832, the memory location pointed by the buffer descriptor corresponding to the sub-data packet plus the length of the second header is used as a starting point, the last bit of the sub-data packet is used as an end point, and the contents from the starting point to the end point in each sub-data packet are copied to the memory location pointed by the current packet length in the first memory space in sequence according to the sorting result, so as to obtain the original data packet.
Example one:
in a specific example, the step of obtaining the original data packet by the second processing unit includes, but is not limited to:
step 1, defining a static variable pBuf for applying 1600 bytes of memory, using a packet, and setting the initial value as NULL. The memory is actually applied when the first 0x9999 type message is encountered. Defining a static variable ulLen for saving the actual length of the group packet, wherein the initial value is 0;
and step 2, taking the current message, and judging whether the type is 0x9999. If not, entering the next step, otherwise entering the step 4;
Step 3, judging ulLen whether 0 is obtained, if 0 is obtained, indicating that no packet is formed, directly uploading the BD-oriented message to the operating system kernel, and entering step 2;
Step 4, judging whether pBuf is empty, if yes, applying for the memory with 1600 bytes length, otherwise, directly entering the next step;
Step 5, copying the memory from the message 16 pointed by the BD to the memory pointed by pBuf + ulLen, wherein the copying length is the length of the message minus 16;
Step 6, grouping packet length ulLen = ulLen +current message length-16;
Step 7, entering step 2
Step 8, the memory with address pBuf and length ulLen is submitted to the kernel of the operating system, and step 2 is entered;
It should be noted that the steps in the specific example are established on the premise that the length of the first packet header field is 16 bytes, the first threshold value is 512 bytes, and the original data packet is smaller than 1600 bytes.
