S200, extracting an IP layer message of the Ethernet data packet by using BRouter technology to obtain a message to be detected;
The message to be detected is obtained by intercepting an Ethernet data packet. The BRouter technique implements traffic ingress at uCPE, i.e., traffic for all clients within the subnet is detected at the BRouter implementation point shown in the figure.
And intercepting and detecting the incoming Ethernet data packet in real time by using BRouter technology, and acquiring an IP layer message in the incoming Ethernet data packet, wherein the IP layer message is used as a message to be detected.
S300, extracting quintuple information in the message to be detected;
In this embodiment, the intelligent path is configured based on a quintuple-based intelligent path technology, and if the intelligent path is used, quintuple information in the message needs to be extracted to determine whether the intelligent path can be used.
S400, detecting the five-tuple information according to a preset matching condition;
The matching condition is used for judging whether the message corresponding to the quintuple information can be sent through the intelligent path based on the quintuple.
S500, if the preset matching condition is met, the Ethernet data packet is sent to a specific application receiving end through a flow optimization path.
When the preset matching condition is met, the Ethernet data packet can access the specific application through the optimization path set for the specific application, so that the purpose of flow optimization is achieved.
As an optional implementation manner of the present application, extracting quintuple information in the message to be detected includes:
extracting five-tuple information from the packet header of the message to be detected;
In this embodiment, the use of BRouter technology for real-time interception of ethernet packets may implement a specific forwarding operation for IP layer packets according to custom logic, where the custom logic is capable of forwarding a specific (if necessary, IP packets destined for microsoft 365) to a preset acceleration tunnel according to five-tuple information in the IP packet header. According to the custom logic, five-tuple information needs to be extracted from the packet header of the message to be detected.
The five-tuple information includes: source IP address, source port number, destination IP address, destination port number, protocol number.
Wherein the source IP address is: the IP address of the source host identifies the initiator of the communication.
The source port number is: port number of process in source host for sending data. It identifies the application or process that initiated the communication.
Destination IP address: the IP address of the target host identifies the recipient of the communication.
Destination port number: the port number of the process in the host for receiving the data. Which identifies the application or process that received the communication.
Protocol number: the protocol number identifies the communication protocol or data format agreed between the sending process and the receiving process, e.g. the protocol number of the TCP protocol is 6 and the protocol number of the udp protocol 17.
As an optional implementation manner of the present application, if the preset matching condition is met, the sending the ethernet packet to a specific application receiving end through a traffic optimization path includes:
Presetting an acceleration tunnel;
Presetting an acceleration router;
The acceleration tunnel is used for connecting the port for acquiring the Ethernet data packet and the acceleration router;
And when the preset matching condition is met, the Ethernet data packet is sent to an acceleration router through a preset acceleration tunnel.
In this embodiment, uCPE is a port for acquiring an ethernet packet, which is added with an acceleration tunnel, and is connected to one of acceleration routers in the internet, typically ECR in SD-WAN system. The traffic flowing to uCPE after the acceleration tunnel is added has two egress directions, one is a gateway and the other is an acceleration router.
UCPE, based on the five-tuple intelligent path function, cooperates with BRouter function to detect the five-tuple of the IP messages of all clients, and is sent to the acceleration router once the preset matching condition is met.
As an alternative embodiment of the present application, the preset matching conditions include:
Taking the IP address and the corresponding port number of the specific application as matching conditions;

Detecting whether the destination IP address and the destination port number in the quintuple information are consistent with the IP address and the corresponding port number of the specific application;
Because there are multiple clients, in the five-tuple information, the destination IP address and the destination port number are paid attention to in this embodiment, for example, according to the destination IP address in the five-tuple information, the ethernet packet sent to microsoft 365 can be known, however, microsoft 365 runs multiple applications, different applications provide different services, and the matching condition records that the port number corresponding to the specific service is partially provided, and at this time, it is detected whether the destination port number is consistent with the port number corresponding to the IP address in the matching condition.
And if the Ethernet data packets are consistent, sending the Ethernet data packets to an acceleration router.
When the destination IP address and the destination port number are respectively consistent with the IP address and the corresponding port number of the specific application recorded in the matching list, the Ethernet data packet is sent to the acceleration router.

The acceleration router determines a specific application receiving end corresponding to a target IP address in the message to be detected according to an IP address table stored by the acceleration router.
And sending the Ethernet data packet to the receiving end of the corresponding specific application through a flow optimization path of the corresponding specific application.
For some specific applications, an optimization path is provided for accessing the specific application, for example, a traffic optimization path is provided for accessing microsoft 365; if the destination IP address in the message to be detected is microsoft 365, the ethernet packet is transmitted by accessing the traffic optimization path of microsoft 365.
As an optional implementation manner of the present application, the port for acquiring the ethernet packet is disposed between the client and the gateway.
In this embodiment, the port for acquiring the ethernet packet is uCPE, and the IP address segment of the gateway and the new IP address segment are not changed and the topology of the existing network is not changed when the ethernet packet is set between the client and the gateway.
As an alternative embodiment of the present application, further comprising:
and if the preset matching condition is not met, sending the Ethernet data packet to a gateway.
In the present embodiment, the case where the preset matching condition is not satisfied is as follows:
The IP address and the port number of the destination are inconsistent with the IP address and the corresponding port number of the specific application recorded in the matching list;
the destination IP address and the destination port number are inconsistent with one of the IP address of the specific application and the corresponding port number recorded in the matching list;
In the above case, the ethernet packet is sent to the gateway, and the gateway sends the ethernet packet to the corresponding application receiving end.
In this embodiment, by detecting the five-tuple of the traffic of all the clients, when the matching condition is not met, the ethernet packet is sent to the gateway, and the gateway sends the ethernet packet to the corresponding application receiving end through the normal path, where the normal path has no specific traffic optimization.
By the method, the quintuple-based intelligent path can be provided for specific application services, users have no perception, clients do not need to be changed, and the purpose of flow optimization can be achieved without changing network topology.
