Description
Technical Field
The present invention relates to the field of computer application technologies, and in particular, to a data forwarding processing method and a server for a 5G data forwarding plane.
Background
The 5G data forwarding plane is a hardware resource and a software resource for forwarding a user's data packet in a 5G network (the 5G network is a fifth generation mobile communication network, the peak theoretical transmission speed of which can reach 1GB per 8 seconds, which is more than 10 times faster than the transmission speed of the 4G network, and for the 5G network, it shows more obvious advantages and more powerful functions in the actual application process).
The 5G data forwarding plane is used for forwarding the data packet of the user in the 5G network, and a program for realizing the data forwarding plane is called a forwarding program. The number of users supported in the 5G network is very large, and the data packets of different users often have different forwarding rules according to the user information in the data packets of the users based on the demand of customizable forwarding of the user traffic. Even different types of packets of the same user have different forwarding rules.
For example, the forwarding processing rules are exemplified as follows:
the user information is assumed to be in the form of a mobile phone number, and of course, may be other forms of user information.
In a server running a forwarding program, perhaps, thousands or even tens of thousands of user data packet forwarding rules are stored, and a set of these forwarding rules is called a forwarding rule table, and when the forwarding program processes a user data packet, the forwarding program needs to search for and match a suitable forwarding rule according to information carried by the data packet.
In order to improve the processing capability of the forwarding program on a single server and reduce the average operation cost of a user, it is easy to think about processing the data packet by adopting a multi-core concurrency (multiple CPU cores forward the data packet simultaneously, each operation core of the CPU can independently operate the program, the multiple operation cores simultaneously operate the program as concurrency, and the CPU cores are the meaning of the CPU cores).
If the forwarding program is simply run on multiple CPU cores, the forwarding capability actually promoted is relatively limited; only one forwarding rule table is in the memory, so that the CPU core running the forwarding program needs to access the one forwarding rule table, and frequent access can cause access memory conflict. If the forwarding rule table is copied to each CPU core, the problem of access memory conflict can be solved, but when a certain rule needs to be added, deleted and changed, all the forwarding rule tables need to be updated synchronously, and when a plurality of forwarding rule tables exist, it is very difficult to update data synchronously and efficiently.
Accordingly, the prior art is still in need of improvement and development.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, the data forwarding processing method of the 5G data forwarding plane according to the preferred embodiment of the present invention includes the following steps:
and S10, when the forwarding program is run on a plurality of CPU cores simultaneously, dividing the forwarding processing rule table into a plurality of forwarding processing rule sub-tables, wherein the forwarding processing rules in each forwarding processing rule sub-table are different from each other, and each CPU core corresponds to one forwarding processing rule sub-table.
Specifically, the 5G data forwarding plane is used for forwarding a data packet of a user in the 5G network, a program for implementing the data forwarding plane is called a forwarding program, in order to improve a processing capability of the forwarding program on a single server, a multi-core concurrent (multiple CPU cores are used for forwarding the data packet simultaneously, each operation core of the CPU can independently operate the program, the multiple operation cores operate the program simultaneously and are called concurrent), the CPU cores (CPU cores are CPU operation cores) load and operate the same forwarding program, and the multiple CPU cores (i.e. multi-core CPUs, collectively referred to as CPUs with multiple operation cores) respectively share a forwarding processing work responsible for a part of the data packet, and the multi-core concurrent is that the multiple CPU cores concurrently operate the forwarding program.
Specifically, a forwarding program is loaded onto a plurality of CPU cores, and the plurality of CPU cores are numbered in sequence respectively; classifying all forwarding processing rules in the forwarding processing rule table into a plurality of forwarding processing rule sub-tables according to the user information in each forwarding processing rule, and numbering the forwarding processing rule sub-tables in sequence respectively; and designating a CPU core corresponding to each forwarding processing rule sub-table, wherein the forwarding processing rules in each forwarding processing rule sub-table are different from each other.
For example, a forwarding program is loaded onto n CPU cores (where n is a positive integer, e.g., n is 8, i.e., the forwarding program is loaded onto 8 CPU cores), and the n CPU cores are numbered: 1,2, 3.), n (when n is 8, i.e., 8 CPU cores are numbered 1-8 in sequence); classifying all forwarding rules in the forwarding rule table into n types according to user information in each forwarding rule, wherein each type corresponds to one forwarding rule sub-table, and sequentially numbering the forwarding rule sub-tables into 1,2 and 3.
For example, CPU core number 1 corresponds to the forwarding rule sub-table number 1, CPU core number 2 corresponds to the forwarding rule sub-table number 2. It can be seen that the number of CPU cores is the same as the number of forwarding processing rule sub-tables, so that each CPU core corresponds to one forwarding processing rule sub-table, that is, a forwarding program running on the CPU core only reads a forwarding processing rule from the forwarding processing rule sub-table, thereby avoiding access memory conflicts (each CPU core only needs to access its corresponding forwarding processing rule sub-table and does not need to access other forwarding processing rule sub-tables), and all forwarding processing rule sub-tables do not need to be updated synchronously (that is, when a forwarding processing rule sub-table needs to add, delete or change a rule, only needs to add, delete or change a rule in its own forwarding processing rule sub-table, and all forwarding processing rule sub-tables do not need to be updated synchronously).
Further, the forwarding program running on each CPU core only reads the forwarding processing rule from the corresponding forwarding processing rule sub-table, and the forwarding program processes the data packet of the user according to the read forwarding processing rule, for example, the forwarding program running on CPU core i only reads the forwarding processing rule from the corresponding forwarding processing rule sub-table i, and the forwarding program processes the data packet of the user according to the read forwarding processing rule.
The user data packet and the forwarding rule table both carry user information identifying the user, and the user data packet and the user information in the forwarding rule table represent the same type of user (even if the expression forms are different, the user data packet and the user information in the forwarding rule table are actually equivalent, namely represent the same type of user, for example, represent the same user); then both the forwarding rules of the same class of users and the packets of the same class of users may be mapped to the same CPU core (e.g., both the forwarding rules of the same user and the packets of the same user may be mapped to the same CPU core, meaning that as long as the users with the same user information may be categorized as the same class of users, in fact, the users may have the same user information but may have only one user or may have multiple users).
Step S20, when a first CPU core in the plurality of CPU cores receives a data packet of a user, the first CPU core acquires a corresponding first forwarding processing rule sub-table, and performs forwarding processing after searching a forwarding processing rule in the first forwarding processing rule sub-table according to the data packet of the user.
Specifically, before the step S20, the network card driver receives the user data packet, and distributes the user data packet to the corresponding CPU core for processing according to the user information in the user data packet, which specifically includes: classifying the data packets of the user according to the user information in the data packets of the user, and transmitting the data packets of the user to the corresponding CPU cores according to the type of the data packet classification of the user; when the CPU core receives the data packet of the user, the CPU core searches the forwarding processing rule from the corresponding forwarding processing rule sub-table to forward the data packet of the user.
For example, users are classified into the i-th class according to user information in the data packet of the users (for example, the class 1 users can include a plurality of users), then the data packet of the users can be sent to the corresponding CPU core i, the CPU core i reads the forwarding processing rule in the corresponding forwarding processing rule sub-table i, and the forwarding program processes the data packet of the class i user according to the read forwarding processing rule.
When a first CPU core (herein, the first CPU core may refer to any one of the n CPU cores, for example, the first CPU core may refer to the CPU core with the number 4, that is, the first CPU core may be denoted as the CPU core i) of the plurality of CPU cores (for example, n, n=8) receives a packet of the user, the first CPU core obtains a corresponding first forwarding rule table (herein, the first forwarding rule table refers to the forwarding rule table corresponding to the first CPU core, and all CPU cores and all forwarding rule tables are in a one-to-one correspondence, for example, when the first CPU core is the CPU core with the number 4, the first forwarding rule table refers to the forwarding rule table with the number 4, that is, the first forwarding rule table may be denoted as the forwarding rule table i), and performs forwarding after searching for the forwarding rule according to the packet of the user (for example, the packet of the class i user) according to the packet of the user.
According to the relation among the CPU core, the forwarding processing rule sub-table and the data packet of the user, the following corresponding relation can be established:
| CPU core 1 | Forwarding processing rule sub-table 1 | Class 1 user data packet |
| CPU core 2 | Forwarding processing rules sub-table 2 | Class 2 user data packet |
| ··· | ··· | ··· |
| CPU core i | Forwarding processing rule sub-table i | Class i user data packet |
| ··· | ··· | ··· |
| CPU core n | Forwarding processing rule sub-table n | Data packet for n-class user |
It can be seen that, as long as the user information in the forwarding rule is the same as the user information in the user's data packet, the forwarding rule of the user and the data packet of the user are necessarily classified into the i-th class, and both correspond to the same CPU core i.
When the CPU core i receives the data packet of the class i user, the forwarding processing rule of the user is quickly inquired from the forwarding processing rule sub-table i and processed, the worry that the forwarding processing rule of the user does not exist in the forwarding processing rule sub-table i is avoided, the other CPU cores also do not need to access the forwarding processing rule sub-table i to cause access conflict, and the forwarding processing rule of the user does not need to be slowly inquired from the forwarding processing rule table with large volume, so that the efficient forwarding processing of the data packet of the user is realized.
When the forwarding program is operated on a plurality of CPU cores, the forwarding processing rule table is divided into a plurality of forwarding processing rule sub-tables, the forwarding processing rules in each forwarding processing rule sub-table are different from each other, each CPU core corresponds to one forwarding processing rule sub-table, namely, the forwarding program operated on the CPU core only reads the forwarding processing rule from the forwarding processing rule sub-table, thereby avoiding access memory conflict, and not needing to synchronously update all forwarding processing rule sub-tables, and after the forwarding processing rule sub-tables are divided into a plurality of forwarding processing rule sub-tables, the data volume in each forwarding processing rule sub-table is far smaller than the data volume in the original forwarding processing rule sub-table, so that the speed of searching the forwarding processing rule of a user in the forwarding processing rule sub-table is far faster than that of the forwarding processing rule in the original forwarding processing rule sub-table, and the speed of forwarding processing is further improved.
Each CPU core only needs to process the data packet of the user matched with the forwarding processing rule in the forwarding processing rule sub-table corresponding to the CPU core, and the data packet of the user and the forwarding processing rule table carry user information for identifying the user, so the invention classifies the forwarding processing rule in the forwarding processing rule table according to the user information to divide the forwarding processing rule sub-table into a plurality of forwarding processing rule sub-tables and appoints the CPU core corresponding to each forwarding processing rule sub-table, and then the network card drive distributes the data packet of the user to the corresponding CPU core for processing according to the user information in the data packet of the user when receiving the data packet of the user, thereby realizing that the forwarding processing rule of one user and the data packet of the user are both corresponding to the same CPU core, and finally achieving the purpose of multi-core concurrent high-speed forwarding processing of the data packet of the user.
Further, as shown in fig. 2, the present invention further provides a corresponding server based on the data forwarding processing method of the 5G data forwarding plane, which includes a processor, and a memory connected to the processor, where the memory stores a data forwarding processing program of the 5G data forwarding plane, and the data forwarding processing program of the 5G data forwarding plane is used to implement the steps of the data forwarding processing method of the 5G data forwarding plane according to the first embodiment when executed by the processor.
In one embodiment, the following steps are implemented when the processor executes a data forwarding handler of the 5G data forwarding plane in the memory:
when a forwarding program is run on a plurality of CPU cores at the same time, the forwarding processing rule table is divided into a plurality of forwarding processing rule sub-tables, the forwarding processing rules in each forwarding processing rule sub-table are different from each other, and each CPU core corresponds to one forwarding processing rule sub-table;
when a first CPU core in the plurality of CPU cores receives a data packet of a user, the first CPU core acquires a corresponding first forwarding processing rule sub-table, and performs forwarding processing after searching forwarding processing rules in the first forwarding processing rule sub-table according to the data packet of the user.
The forwarding program running on each CPU core only reads the forwarding processing rule from the corresponding forwarding processing rule sub-table, and the forwarding program processes the data packet of the user according to the read forwarding processing rule.
The user data packet and the forwarding rule table both carry user information for identifying the user.
When the forwarding program is run on the multiple CPU cores simultaneously, the forwarding processing rule table is divided into multiple forwarding processing rule sub-tables, the forwarding processing rules in each forwarding processing rule sub-table are different, and each CPU core corresponds to one forwarding processing rule sub-table, and the method specifically comprises the following steps:
