Problems solved by technology

[0004] However, the bandwidth on the DSL link between HG1 and HG2 and the Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access Multiplexer, DSLAM) can be guaranteed, but the DSLAM passes through the router (Router) to the HAAP. There is an IP link between them, and the bandwidth provided to each

Example Embodiment

[0065] Example 1

[0066] figure 2 A flow chart of a method for distributing traffic provided by an embodiment of the present invention. A first data link and a second data link are connected between a first network node and a second network node, and a first data link is established on the first data link. There is a first forwarding tunnel from the first network node to the second network node, and the first network node and the second network node are respectively tunnel endpoints of the first forwarding tunnel.

[0067] It can be seen that the embodiment of the present invention is mainly applied in the scenario of using the hybrid access mode to access the network, and two or even more data links are respectively connected between two network nodes, and the first network node and the second network node are connected with each other. The first data link is used as the priority data link for forwarding traffic between two network nodes, that is, only when the traffic for...

Abstract

The embodiment of the invention discloses a flow distribution method and device. The method comprises the following steps: calculating the first packet loss rate of a first forwarding tunnel within the preset cycle by a first network node; when the first packet loss rate is smaller than a first preset threshold value, reducing the rated bandwidth of the first forwarding tunnel by a first preset bandwidth to obtain a first available bandwidth; when the forwarding flow of the first forwarding tunnel exceeds the first available bandwidth, distributing the exceeded forwarding flow to a second data link for forwarding. According to the method, the available bandwidth of the first forwarding tunnel is reduced to be the first available bandwidth by the first network node when the packet loss rate of the first forwarding tunnel is relatively high; as the first available bandwidth is smaller than the original available bandwidth of the first forwarding tunnel, the forwarding flow can early exceed the first available bandwidth, the flow distribution opportunity of the first network node is advanced, and the serious packet loss possibility before flow distribution is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for splitting traffic. Background technique [0002] Hybrid Access (Hybrid Access, HA) is currently a relatively common way for user terminals to connect to the network. The so-called hybrid access mode means that the user terminal is connected to the network through multiple different types of data transmission links at the same time. A typical application scenario in the hybrid access mode is that a user terminal is connected to the network through a Digital Subscriber Line (Digital Subscriber Line, DSL) link and a Long Term Evolution (Long Term Evolution, LTE) link at the same time. [0003] figure 1 It is a network topology diagram of a hybrid access network, such as figure 1 As shown, a PC (personal computer), that is, a user terminal, is connected to a home gateway (Home Gateway, HG), and there is a DSL link and an LTE link between the HG and a hybrid access ...
