Fig. 2 is a schematic flowchart of a message distribution method provided by another embodiment of the present invention, which is applied to a scenario where a network side device sends a message to a user device through a wireless gateway. As shown in Fig. 2, the message distribution method of this embodiment Methods can include:

201. The communication interface receives a packet, where the packet includes a destination IP address, where the destination IP is the IP address of a user equipment that receives the packet.

Wherein, the communication interface is a communication interface in the wireless gateway, and the communication interface receives a message sent from the network side device to the user equipment, and the message includes a destination IP address, and the destination IP is the user who finally receives the message The IP address of the device.

Wherein, the IP address of the user equipment is an IP address allocated to the user equipment by the wireless gateway when the user equipment establishes a connection with the wireless gateway.

202. The communication interface hashes the message to the first processor by using a hash function according to the IP address.

Specifically, according to the IP address, the communication interface uses a hash function to determine the first processing identifier corresponding to the IP address; wherein, the first processing identifier is usually the serial number of the first processor.

According to the first processing identifier, sending the packet to the first processor pointed to by the first processing identifier.

During specific implementation, the above-mentioned hash function may specifically be: i=f(IpAddr, M); wherein, IpAddr is the IP address of the user equipment, M is the number of processors in the wireless gateway, and i represents the IP address according to the user equipment and the number M of processors, and the processing identifier (the number of the processor) hashed to by the user equipment obtained by calculating through the hash function.

Assuming that the number of user equipments is relatively large, the user equipments can be evenly distributed to each processor through the hash function f. For example, the hash function f(IpAddr, M)=IpAddr mod M, mod is a modulo calculation, that is, the remainder obtained by dividing M by IpAddr. Assuming that the number of processors M=3, the numbers of the three processors are 0, 1, and 2 respectively; assuming that there are 10 user devices, the IP addresses are 1, 2, 3, 4, 5, 6, 7, and 8 respectively , 9, 10; through the calculation of the hash function, the remainder after the IP addresses are 3, 6, and 9 when they are divided by 3 is 0, that is, IpAddr mod 3=0, therefore, the IP addresses corresponding to 3, 6, and 9 can be The user equipment is hashed to processor No. 0 for processing. Similarly, through the calculation of the hash function, the remainder after the IP address is 1, 4, 7, and 10 is 1, and the IP address is 1, 4, 7, and 10 The corresponding user equipment is hashed to processor No. 1 for processing. Similarly, the remainder after the IP address is 2, 5, and 8 is 2, and the user equipment corresponding to IP address 2, 5, and 8 is hashed to No. 2. processor processing.

203. The first processor searches a preset hashed user forwarding table according to the IP address, and determines a second processor where the context information of the user equipment corresponding to the IP address resides.

During specific implementation, before step 203, assuming that the user equipment selects the second processor when establishing a connection with the wireless gateway, the second processor will create the context information of the user equipment, and the context information saves the process and sends it to the user equipment information required by the message;

After the wireless gateway assigns an IP address to the user equipment, the second processor uses a hash function to determine the first processing identifier corresponding to the IP address of the user equipment according to the IP address of the user equipment. The content of the function can refer to the relevant description in step 202, and will not be repeated;

Therefore, the communication interface does not need to save the corresponding relationship between the processing identifier where the context information of each user equipment is located and the IP address of the user equipment, thereby avoiding the performance bottleneck of searching the forwarding table of the communication interface.

204. The first processor sends the packet to the second processor, so that the second processor sends the packet to the second processor according to the context information of the user equipment corresponding to the IP address user equipment.

According to the embodiment of the present invention, according to that the message received by the communication interface includes the destination IP address, the message is hashed to the first processor by using a hash function; so that the first processor searches for the preset IP address according to the IP address. Hashing the user forwarding table, determining the second processor where the context information of the user equipment corresponding to the IP address resides, and sending the message to the second processor, so that the second processor according to The context information of the user equipment corresponding to the IP address, and sending the packet to the user equipment. Since the hashed user forwarding table only saves the correspondence between the processing identifiers where the context information of some user equipments is located and the IP addresses of some user equipments, the IP address can be quickly found according to the destination IP address included in the message. The processor where the context information of the user equipment corresponding to the address is located sends the message to the corresponding user equipment through the processor where the context information of the user equipment is located, which can improve the efficiency of message distribution.

Because this embodiment does not need to look up the table through the forwarding table of the communication interface, the performance bottleneck of searching the forwarding table of the communication interface can be avoided, so it can solve the problem that the performance bottleneck of the forwarding table of the communication interface can easily lead to the decline of message distribution efficiency .
