specific Embodiment

[0039] Such as figure 2 As shown, the multi-mode terminal MN has two network interfaces, one accesses the Internet through 3G, and the other accesses the Internet through WIFI. The multi-mode terminal MN has a service flow dataflow that is using the WIFI network for data communication. With the movement of the multi-mode terminal MN, the local area network WIFI network has a large-scale network oscillation at this time, and the current mobile data (2G, 3G, 4G) network signal is relatively weak. At this time, switching dataflow to any interface will not effectively improve user experience. By establishing a distribution strategy, all communication data dataflow is distributed to two interfaces for simultaneous transmission, that is, the bandwidth of the two interfaces is aggregated, so that Even in the case of poor network conditions, existing network resources can be fully utilized to achieve bandwidth aggregation, effectively improving the user's online experience.

Abstract

The invention discloses a MIPv6-based multi-mode terminal service flow distribution method. The method comprises the following steps that: a service flow distribution strategy is established, and specified service flow is distributed to corresponding interfaces; a routing management module establishes a routing table, monitors a local interface state, and maintains the routing table; the routing management module establishes strategy routing according to the service flow distribution strategy; a service flow management module captures data packets, and analyzes the captured data packets; an operating system performs TOS (Type of Service) setting on the data packets through an iptables tool; and the routing management module receives and transmits the data packets according the strategy routing. When a multi-mode terminal is in a heterogeneous network of which various network quality is poor, certain service flow can be selectively distributed to a plurality of interfaces to be transmitted at the same time, so that a flexible transmission way is realized; the transmission efficiency is increased; existing network resources can be utilized fully; and bandwidth aggregation is realized.

Description

technical field [0001] The invention relates to the technical field of service flow distribution, in particular to an MIPv6-based multi-mode terminal service flow distribution method. Background technique [0002] At present, multi-mode terminals are increasingly popular, and IPv6 networks have entered the deployment stage. Consider the following scenario. When the network environment where the multi-mode terminal is located is not good, for example, the WiFi and Lan network environments are congested. At this time, switching the service flow to any interface will not significantly improve the communication quality. . Therefore, currently, a service flow can be distributed to several interfaces for simultaneous transmission, so that multiple interfaces can share the communication requirements of the service flow and realize bandwidth aggregation. Most of the existing solutions do not support service flow distribution of multi-mode terminals. [0003] In "Research on Multi...
