Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
According to an aspect of the present invention, an embodiment of the present invention provides a packet forwarding method, as shown in fig. 1, which may include the steps of:
s1, responding to the received message, acquiring the IP address of the message;
s2, obtaining the value corresponding to the preset field of the preset byte in the IP address of the message;
s3, responding to the fact that the values corresponding to the preset fields of the preset bytes are not all 1, and obtaining rules corresponding to the preset fields;
s4, calculating a decimal value corresponding to the preset field;
s5, determining a forwarding port according to the decimal value and the rule to forward the message by using the forwarding port.
The scheme provided by the invention can be used for load sharing under the specific flow condition, and can flexibly design a shunting mode according to the current flow condition.
In some embodiments, in step S1, in response to receiving the message, an IP address of the message is obtained, specifically, each byte in the IP address is obtained as an 8-bit binary string, for example, for the IP address 10.1.1.1, where the third byte 10 may be represented as 00001010, the second byte 1 may be represented as 00000001, the first byte 1 may be represented as 00000001, and the 0 th byte 1 may be represented as 00000001, so that one IP address may be represented by a 32-bit string.
In some embodiments, if the IP address is 1 at step and incremented 512 times, the upper 16 bits do not change in the model, but require homology and homing, so the upper 16 bits need full attention to ensure accurate matching of traffic into the model; shunting by taking 4 bits as a unit in the lower 16 bits; when the flow cannot be completely equalized, 3 bits are derived from the upper bits, and the flow is redistributed.
In some embodiments, obtaining a value corresponding to a preset field of a preset byte in an IP address of the packet further includes:
and judging whether the values corresponding to the Nth preset field of the first preset byte in the IP address are all 1.
In some embodiments, in response to that the values corresponding to the preset fields of the preset bytes are not all 1, obtaining the rule corresponding to the preset fields, further includes:
and responding to the situation that the values corresponding to the Nth preset field are not all 1, and acquiring a rule corresponding to the Nth preset field.
Specifically, the lower 4 bits of the lower 16 bits are used as a first preset field, that is, the lower 4 bits of the 0 th byte are used as preset fields, and whether the fields are all 1 is determined, for example, for the IP address 10.1.1.1, the two-level system corresponding to the 0 th byte is represented as 00000001, the lower 4 bits are 0001, and not both 1, a rule corresponding to the first preset field is matched, then step S4 is performed, a decimal value, that is, 1, corresponding to the value corresponding to the preset field is calculated, and then a corresponding forwarding port is found in the rule according to the decimal value (that is, 1), so as to forward the packet using the port.
In some embodiments, further comprising:
responding to the condition that the values corresponding to the Nth preset field are all 1, and judging whether the values corresponding to the (N + 1) th preset field adjacent to the Nth preset field are all 1;
and responding to the condition that the values corresponding to the N +1 preset fields are not all 1, and acquiring the rule corresponding to the N +1 preset fields.
Specifically, for example, for the IP address 10.1.1.63, the two-level system corresponding to the 0 th byte is represented as 00111111, the lower 4 bits thereof are 1111 bits and are all 1 bits, the rule corresponding to the second preset field (011 in 0011) is matched, that is, 3 bits are derived from the upper bits, then step S4 is performed, the decimal value corresponding to the preset field, that is, 3(011 obtained), is calculated, and then the corresponding forwarding port is found in the rule according to the decimal value (that is, 3) to forward the packet using the port.
Similarly, if the values in the second preset field are all 1, 3 bits are derived from the high order bits as the third preset field, and at this time, since the 0 th byte has only 8 bits, the value corresponding to the 1 st byte needs to be matched. The 1 st byte is also represented by 8 bits, the 0 th byte and the 1 st byte have 16 bits in total, if the lower 4 bits (the first preset field) and the upward derivative 3 bits (the second preset field is 1), the third preset field (the highest bit of the 0 th byte and the lower 2 bits of the 1 st byte) is matched with the rule, the decimal value corresponding to the third preset field (the highest bit of the 0 th byte and the lower 2 bits of the 1 st byte) is calculated, then the corresponding forwarding port is found in the rule according to the decimal value (namely 3), so that the port is used for forwarding the message, and so on.
