Problems solved by technology

[0003] Among them, the load balancing technology can only achieve multi-link equal ratio load balancing or load sharing and forwarding traffic according to a fixed ratio, and needs to occupy all links for forwarding. The flexibility is poor
Policy routing technology can only select a link for each type of business to forward data packets. If the business traffic exceeds the bandwidth of this link, packet loss will occur.
[0004] However, in actual data communication multi-link usage scenarios, it is often necessary to realize the requirement of link load forwarding for data packet classification and splitting, which cannot be realized by existing technologies.

Abstract

The embodiment of the invention discloses a data forwarding method and device, and relates to the communication field. The demand of performing link load forwarding on the data message classification shunt flow can be realized, and the flexibility of the multi-link load forwarding is improved. The data forwarding method comprises the following steps: acquiring data messages; measuring the flow of the data messages with the same service type in the data messages; marking the flow belonging to the promised access rate in the data messages with the same service type as a first forwarding marker; and forwarding the data message with the first forwarding marker identifier according to the preset strategy routing. The method and device disclosed by the embodiment of the invention are used for data forwarding.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a data forwarding method and device. Background technique [0002] At present, in the process of data communication, there is an application scenario where data packets are transmitted to the same destination and use multiple links with the same cost. In this scenario, effective technologies and methods are needed to load-share and forward traffic on multiple links. Currently, the main common technologies are link load balancing technology and policy routing technology. [0003] Among them, the load balancing technology can only achieve multi-link equal ratio load balancing or load sharing and forwarding traffic according to a fixed ratio, and needs to occupy all links for forwarding traffic, which has poor flexibility. Policy routing technology can only select a link for each type of service to forward data packets, and packet loss will occur if the service ...
