Background
In recent years, high-bandwidth services represented by video on demand, network games, online education, live webcasts, network offices, and IPTV are gradually regarded as new service growth points by telecommunication operators and radio and television operators, and the demand of network users for broadband services has increased. In this case, the GPON router of FTTH is widely applied to home subscribers.
The FTTH (fiber to the user) optical access network technology has obvious advantages in terms of access physical rate, bandwidth efficiency and optical separation ratio, full-service carrying capacity and security, and thus becomes a preferred technology in the optical access era.
The ONU is placed in the home of the user. A passive optical distribution network is adopted between the OLT and the ONU and mainly comprises an optical splitter and an optical fiber, and the OLT can be arranged at a far end or in a cell machine room.
The traditional acceleration method is downloading acceleration software, but the acceleration software can only provide a single network acceleration service, for example, the speed thunder only provides downloading acceleration. The user needs to install a plurality of software. Acceleration services for specific applications (such as online gaming) are provided on some routers, which simply accelerate certain services through the main processor unit. No further services can be accelerated. The network acceleration system based on the GPON router, which is provided for solving the problems, can accelerate most of applications of customers by reasonably using a software and hardware acceleration mode without independently setting acceleration service. More users can enjoy high-quality broadband service.
Disclosure of Invention
The present invention is directed to a network acceleration system based on GPON router to solve the above problems in the background art.
In order to achieve the purpose, the invention provides the following technical scheme:
a network acceleration system based on a GPON router comprises a configuration module, a server module, a software acceleration module, a hardware acceleration module and a software and hardware acceleration rule autonomous learning module, wherein the configuration module is a configuration acceleration parameter and debugging module and comprises a network acceleration setting end module and a user end interface, and the configuration module is used for setting parameters of an acceleration rule, such as the number of soft acceleration and a hardware acceleration threshold; the server-side module is connected with the software acceleration module and the software and hardware acceleration rule autonomous learning module, and is used for analyzing the parameters of the configuration module and setting the parameters into the software acceleration module, the hardware acceleration module and the software and hardware acceleration rule autonomous learning module; the hardware acceleration module is connected with the server module through the software and hardware acceleration rule autonomous learning module.
The GPON router learns the data stream conversion rule through a software and hardware acceleration rule learning module and judges whether the rule is put into an acceleration rule memory in a hardware data stream accelerator according to a threshold value of the data stream, if the data stream speed of the hardware acceleration module is reached, the acceleration rule is configured into the hardware acceleration module, and if the data stream speed of the hardware acceleration module is not reached, the acceleration rule is put into a software acceleration module; if the data flow reaches the rule threshold value of the hardware acceleration module, the rule put into the software acceleration module is also added into the hardware acceleration module, so that the hardware acceleration module can bear the data flow with large data flow for processing, the software acceleration module bears the data flow with less flow, and the use resources of the processor are reasonably allocated.
The rule matching field comprises a commonly used 5-tuple, a network address after address conversion and a port number; therefore, if the subsequent network data packet is matched with the corresponding rule, the acceleration module of the GPON router directly modifies the data packet according to the matching rule and forwards the modified data packet, and the CPU is not needed to process the modified data packet, so that the utilization rate is reduced.
Of course, the number of the rules for hardware acceleration is limited, and the cost of the accelerator is too high due to too many storage rules, and the number of the currently selected storage hardware acceleration rules is 2K.
If the rule storage of the hardware data flow accelerator is full, the subsequent learned data flow rules are stored in the memory of the GPON router and processed by the software accelerator.
The software accelerator records relevant fields of rules in a packet receiving function record packet and a packet sending function record packet of the connection tracking on the running network operating system based on the Linux system into one session in a linked list. The linked list of the session information is a hash table based on 5 tuples, and quick searching can be realized.
The number of the acceleration rules which can be stored in the software acceleration system in the GPON router acceleration system is not less than 4K. After the software acceleration rule is learned, the subsequent data packet is matched and then directly sent out by skipping the routing process of the Linux system, so that the routing time is saved.
Compared with the prior art, the invention has the advantages that: the network acceleration system is a GPON router, realizes acceleration of a plurality of broadband application services of home users by comprehensively and reasonably using software and hardware resources, and does not need to download software or configure specific applications. Network delay and congestion are reduced, and the experience of broadband service application of a user is improved. Meanwhile, the cost of the GPON router can be reduced by reasonably using software and hardware for acceleration.

The GPON router learns a data stream conversion rule through a software and hardware acceleration rule learning module, judges whether to put the rule into an acceleration rule memory in a hardware data stream accelerator according to a threshold value of the data stream, configures the acceleration rule into the hardware acceleration module if the data stream rate (such as 8Mbps) of the hardware acceleration module is reached, and puts the rule into a software acceleration module if the data stream rate is not reached; if the data stream reaches the rule threshold (for example, 8Mbps) of the hardware acceleration module, the rule put into the software acceleration module is also added into the hardware acceleration module, so that the hardware acceleration module can bear large data stream volume for processing, the software acceleration module bears data stream with less flow volume, and the use resources of the processor are reasonably allocated.
The rule matching field comprises a commonly used 5-tuple (protocol name, source IP address, destination IP address, source port number and destination port number) and also comprises a network address and a port number after address conversion; therefore, if the subsequent network data packet is matched with the corresponding rule, the acceleration module of the GPON router directly modifies the data packet according to the matching rule and forwards the modified data packet, and the CPU is not needed to process the modified data packet, so that the utilization rate is reduced.
Of course, the number of the rules for hardware acceleration is limited, and the cost of the accelerator is too high due to too many storage rules, and the number of the currently selected storage hardware acceleration rules is 2K. If the rule storage of the hardware data flow accelerator is full, the subsequent learned data flow rules are stored in the memory of the GPON router and processed by the software accelerator.
The software accelerator records relevant fields of rules in a packet receiving function record packet and a packet sending function record packet of the connection tracking on the running network operating system based on the Linux system into one session in a linked list. The linked list of the session information is a hash table based on 5 tuples, and quick searching can be realized. The number of the acceleration rules which can be stored in the software acceleration system in the GPON router acceleration system is not less than 4K.
