In the home gateway device, some application functions such as wired or WIFI internet access, voice, video and the like need to perform targeted processing on the service message according to application requirements. For example, modifying the packet content, including MAC address, VLAN, IP address or user-defined field, etc.; or, specify a queue number for the packet, a GEM Port-Id, etc. (where GEM Port-Id exists only at a GPON/XG-PON type gateway device, and an EPON type gateway does not have this functionality).
The implementation of these application functions requires that the service packet is captured and processed, and then forwarded according to the original packet path, that is, in the technical field of network communication, the network card driver, the kernel protocol stack, and the data transmission between the kernel mode and the user mode are required. Whereas the prior art generally employs: after entering the gateway device from the user port, the message is forwarded through the kernel protocol stack, and then the hook is hung on the sending end driven by the network card to capture and process the message. The method firstly needs to store the forwarding information and service configuration related to the message, and is used for searching the related information when the message is finally forwarded; then, capturing the message twice, capturing and analyzing the message for the first time, and processing the message according to the service function requirement; and secondly, when the message is finally sent, capturing and analyzing the message again, searching the stored configuration information table, searching corresponding forwarding information according to the content of the message, modifying the head of the message, and adding forwarding information identifiers including a queue number, a GEM Port-Id, a VLAN and the like so as to achieve correct forwarding of the message. The method has the advantages that the operation of analyzing, searching and processing twice exists in a kernel mode aiming at the same message; the message forwarding is realized by pure software. When a large number of service messages appear, CPU resources are occupied, and the forwarding efficiency is low.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a packet asynchronous forwarding system based on a Linux operating system, which includes a packet receiving module, an application module, and a packet sending module.
Wherein, receive the packet module, it is used for: receiving an original message in a kernel state, obtaining a first message containing a network card driving source port number based on the original message, and forwarding the first message from the kernel state to a user state;
an application module to: receiving and processing the first message in a user mode to obtain a second message retaining the network card driving source port number, and forwarding the second message from the user mode to a kernel mode;
a hair pack module for: and receiving the second message in the kernel state, searching the corresponding network equipment according to the network card driving source port number, constructing a final message based on the second message, and sending the final message to the kernel protocol stack.
Specifically, the original packet in this embodiment includes a first SKB packet header and a first payload, where SKB (Struct sk _ Buffer) is in a linux TCP/IP stack and is used to manage a Data Buffer structure. Data packets transmitted in the linux network generally consist of an SKB data structure (i.e., an SKB header) and data packet contents (i.e., a data packet payload). After the first SKB packet header is analyzed, port number information (i.e., a network card driving source port number) and information of a first packet length, which are forwarded by the network card driver in the original message, can be obtained, and the original message is added into a local queue for caching, and then the first message including the network card driving source port number, the first packet length and the first packet payload is forwarded from the kernel state to the user state.
As a better implementation manner, the packet receiving module receives the original message in the kernel state by hanging a hook at the receiving end driven by the network card.
Further, the application module in this embodiment, according to the requirement of the application function, where the application function refers to functions of wired or WIFI internet access, voice, video, and the like, and generally, the application function performs targeted processing on the packet, and in this embodiment, the application module is specifically configured to modify the first packet length and the first packet payload, that is, modify the first packet length to the second packet length, modify the first packet payload to the second packet payload, and simultaneously reserve the network card drive source port number, so that a second packet including the second packet length, the second packet payload, and the network card drive source port number can be obtained, and then forward the second packet from the user mode to the kernel mode. Because the processing of the message in the embodiment is realized in the user mode, the CPU overhead is reduced because the kernel is not occupied for a long time in the process, and the system processing performance of the high-priority service is improved.
In addition, the first packet payload in this embodiment includes a source MAC address and a destination MAC address, a source IP address and a destination IP address, or a source port number and a destination port number of the ethernet packet. The three different combinations of source and destination MAC addresses, source and destination IP addresses, or source and destination port numbers can all act as identifiers for the packets. In the process of converting the original packet into the first packet, since the payload of the first packet does not change, the ethernet packet may refer to the original packet or the first packet.
Further, the packet sending module constructs a second SKB packet header based on the network card drive source port number and a second packet length, takes a message containing the second SKB packet header and a second packet payload as a final message, and then sends the final message back to an entrance where a Linux operating system kernel protocol stack receives a data packet.
In the prior art: after entering the gateway device from the user port, the message is forwarded through the kernel protocol stack, and then the hook is hung on the sending end driven by the network card to capture and process the message. The method firstly needs to store the forwarding information and service configuration related to the message, and is used for searching the related information when the message is finally forwarded; then, capturing the message twice, capturing and analyzing the message for the first time, and processing the message according to the service function requirement; and secondly, when the message is finally sent, capturing and analyzing the message again, searching the stored configuration information table, searching corresponding forwarding information according to the content of the message, modifying the head of the message, and adding forwarding information identifiers including a queue number, a GEM Port-Id, a VLAN and the like so as to achieve correct forwarding of the message.
Compared with the prior art, the invention realizes that the message is received in the kernel mode, processed in the user mode and then sent back to the kernel protocol stack. In addition, the network card driving source port number is reserved in the whole processing process, so that the message can still be forwarded according to a correct path before being captured and processed without storing message forwarding information and service configuration information in a kernel state, and the operations of higher system processing priority and more CPU resource occupation are realized by message analysis, searching comparison and message modification when the message is captured by the sending end of the network card driving. Meanwhile, after the message processed by the application module is sent to the kernel protocol stack receiving data packet inlet through an asynchronous forwarding mechanism, the message can be continuously subjected to hard forwarding or soft forwarding according to the original path according to the message forwarding rule, and the forwarding efficiency is further improved. In conclusion, the invention reduces the soft processing flow of the message, reduces the CPU overhead, improves the forwarding efficiency of the message processed by the CPU, and indirectly improves the system processing performance of the high-priority service.

Because the processing of the message in the embodiment is realized in the user mode, the CPU overhead is reduced because the kernel is not occupied for a long time in the process, and the system processing performance of the high-priority service is improved.
And S3, receiving the second message in the kernel state, searching the corresponding network equipment according to the network card driving source port number, constructing a final message based on the second message, and sending the final message to the kernel protocol stack.

Meanwhile, after the message processed by the application module is sent to the kernel protocol stack receiving data packet inlet through an asynchronous forwarding mechanism, the message can be continuously subjected to hard forwarding or soft forwarding according to the original path according to the message forwarding rule, and the forwarding efficiency is further improved. In conclusion, the invention reduces the soft processing flow of the message, reduces the CPU overhead, improves the forwarding efficiency of the message processed by the CPU, and indirectly improves the system processing performance of the high-priority service.
