Technical Field
The present invention relates to the field of data network communications, and in particular, to a method and an apparatus for adjusting traffic.
Background
With the rapid development of global information industry, the increasing popularization of internet multimedia application and intelligent terminals, the data flow in the network is larger and larger, and thus the requirements on the performance such as bandwidth, time delay and the like are higher and higher. The above-mentioned requirements cannot be met if the data traffic is forwarded over a single link. Therefore, multiple forwarding paths need to be established according to different routes, and data traffic is balanced by a certain rule and distributed to different links for forwarding, so as to optimize forwarding.
The current traditional processing method is to differentiate the traffic by the characteristics of the packet, such as five-tuple information (source IP address, source port, destination IP address, destination port, and transport layer protocol) or to allocate the traffic to different links per packet. However, these processing methods only focus on distributing traffic to different links, and do not consider the actual processing capability of the downstream node, that is, after the traffic is balanced to the downstream device, the traffic may be dropped due to its performance problem.

In the case where only part of the interface is enabled, the protocol packet is multicast to the enabled interface through the disabled interface, so that the upstream device receives the protocol packet sent by the first downstream device through the enabled interface.

It is worth mentioning that the upstream device may adjust the traffic forwarded to the first downstream device to the second downstream device in one of three ways:
adjusting traffic forwarded to the first downstream device over a particular link onto the second downstream device;

The self IP address refers to the IP address of the interworking interface of R2 with the upstream device.
After receiving the protocol message, the upstream devices R1 and R2 may check the load sharing information related to the device, and if the R2 finds that the data forwarded to the R3 has other equivalent paths, such as R4, the forwarding path is adjusted, and the subsequent message is forwarded to other devices R4 on the equivalent path, so as to avoid the problem of packet loss when the message is forwarded to the R3.
