Description
Technical Field

Because the image is a remote image, the message received and sent by the Port5 on the SW5 needs to be encapsulated into a sampling message, the source Internet Protocol (IP) address of the sampling message is the IP address of the Port5 on the SW5, and the destination IP address of the sampling message is the IP address of the sampling service, and then the sampling message is sent to the sampling server.
In fig. 1, although there are many links from the sampling device to the sampling server, if a packet at the same port on the same device is collected, the source IP address, the destination IP address, the source port, and the destination port of the packaged sampled packet are all the same, the equalization factor of the current equalization algorithm is usually related to the source IP address, the destination IP address, the source port, and the destination port, so that the sampled packet of one sampling device only selects the same link to forward at each time, as the link identified by the dashed line with an arrow in fig. 1.
In the above method for forwarding the sample packet, if the number of the sample packet is large, the excessive bandwidth of the link identified by the dotted line with the arrow is occupied, which affects forwarding of the normal service packet on the link, and other links may be in an idle state, and the bandwidth utilization rate of other links is low, thereby causing link load imbalance of the whole data center.

Detailed Description
For a problem of link load imbalance of the entire data center in the prior art, an embodiment of the present invention provides a method for forwarding a sample packet, where the method is applied to a sampling source device included in the data center, an architecture diagram of the data center may refer to the architecture shown in fig. 1, and the source device is a device configured with an sFlow sampling function in the data center, and may be, for example, SW5 in fig. 1. The flow of the method is shown in fig. 2, and the specific execution steps are as follows:
s21: and establishing communication connection with sampling destination equipment included in the data center.
The sampling destination device is a device connected to a sampling server included in the data center, and may be one device or a plurality of devices, for example, in the case of a plurality of devices shown in fig. 1, the sampling destination device in fig. 1 is SW2(SW2 includes SW2-1 and SW2-2 constituting a virtual switching unit). After the data center is established, in order to implement the method in this embodiment, the sampling source device needs to establish a communication connection with the sampling destination device, which may be, but is not limited to, a Transmission Control Protocol (TCP) connection.
S22: and synchronizing the IP address of the sampling source equipment and the random IP address list to the sampling destination equipment so that the sampling destination equipment establishes the mapping relation between the IP address of the sampling source equipment and the random IP address list.
In order to enable the sampling destination device to establish a mapping relationship between the IP address of the sampling source device and the random IP address list, the sampling source device needs to synchronize the IP address of the sampling source device and the random IP address list to the sampling destination device.
The random IP address list may be set according to actual needs, and for example, may include: 1.1.1.1-1.1.1.254, totaling 254 IP addresses, and if the IP address of the sampling source device is 192.168.1.1, the sampling source device can synchronize 192.168.1.1 and 1.1.1.1-1.1.1.254 to the sampling destination device.
S23: and packaging the acquired message by taking one IP address in the random IP address list as a source IP address to obtain a sampling message.
When the sampling source device receives and sends the messages, the messages can be collected, then the header information is added outside the messages and encapsulated into the sampling messages, wherein the source IP address of the sampling messages is not the IP address of the sampling source device but one IP address in the random IP address list, the IP address can be randomly obtained from the random IP address list or obtained from the random IP address list according to the sequence, and the specific implementation mode can be determined according to the actual situation.
Continuing with the above example, 1.1.1.10 may be selected from the random IP address list as the source IP address of the sample packet.
S24: and sending the sampling message to the sampling destination equipment so that the sampling destination equipment changes the source IP address into the IP address of the sampling source equipment according to the mapping relation and forwards the sampling source equipment to the sampling server.
The sampling source device sends the sampling message in S23 to the sampling destination device, and in order to ensure that the sampling server correctly performs sampling analysis on the sampling source device, the sampling destination device needs to change the source IP address of the sampling message to the IP address of the sampling source device according to the mapping relationship in S22.
Continuing with the above example, the sampling destination device determines that the IP address of the sampling source device corresponding to 1.1.1.10 is 192.168.1.1 according to the mapping relationship, and therefore, directly changes 1.1.1.10 to 192.168.1.1 and forwards the result to the sampling server.
According to the scheme, the messages of the same port on the same equipment are collected, the source IP addresses of the sampling messages obtained by encapsulation are different, the balance factors of the balance algorithm used when different sampling messages are forwarded can be directly influenced to be different, even if the links selected by the sampling messages of the same port on the same sampling equipment at each time are different, the load balance of all the links of the whole data center can be ensured, and the bandwidth utilization rate of all the links is improved.
Specifically, the establishing of the communication connection with the sampling destination device included in the data center in S21 includes:

and if the IP address list does not pass the conflict detection, deleting the conflicting IP address from the random IP address list, and synchronously sampling the IP address of the source device and the random IP address list for deleting the conflicting IP address to the sampling destination device.
Sometimes two different devices in a data center may have the same IP address, and to avoid this, collision detection is required. In this embodiment, collision detection may be performed on the IP addresses in the random IP address list before the IP address of the source device and the random IP address list are synchronously sampled to the sampling destination device, and if the collision detection is passed, it is indicated that the IP addresses of the devices in the data center are not included in the random IP address list, and the IP address of the source device and the random IP address list may be synchronously sampled to the sampling destination device directly; if the IP addresses of the partial devices of the data center do not pass the conflict detection, the IP addresses of the partial devices of the data center are included in the random IP address list, and after the conflicting IP addresses need to be deleted from the random IP address list, the IP address of the source device is synchronously sampled to the sampling destination device, and the random IP address list of the conflicting IP addresses is deleted.

S35: and after the source IP address is changed into the IP address of the sampling source device according to the mapping relation, forwarding the IP address to the sampling server.
In order to ensure that the sampling server correctly performs sampling analysis on the sampling source device, the sampling destination device needs to change the source IP address of the sampling packet to the IP address of the sampling source device according to the mapping relationship in S33.
According to the scheme, the messages of the same port on the same equipment are collected, the source IP addresses of the sampling messages obtained by encapsulation are different, the balance factors of the balance algorithm used when different sampling messages are forwarded can be directly influenced to be different, even if the links selected by the sampling messages of the same port on the same sampling equipment at each time are different, the load balance of all the links of the whole data center can be ensured, and the bandwidth utilization rate of all the links is improved.
