Abstract

The invention provides a data transmission method, a data transmission device and a data transmission system. The method comprises that: a router shares a data transmission load to a plurality of load sharing links in a stream-by-stream way, and detects the utilization rates of each load sharing link; and if the maximum link utilization rate of the load sharing link is judged to be greater than a switching threshold value, and the ratio of the maximum link utilization rate to the minimum link utilization rate of the load sharing link is judged to be greater than a ratio threshold value, the router switches the stream-by-stream mode into a packet-by-packet mode. In the method, the router can switch a load sharing mode according to the actual utilization conditions of each load sharing link. By the method, the device and the system, the problems of traffic load sharing unbalance and serious packet loss when the number of streams in a network is relatively lower in the independent adoption of the stream-by-stream mode are solved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a data transmission method, device and system thereof. Background technique [0002] Route load sharing is an effective means to improve the reliability of IP transmission. Currently, there are two main implementation forms of routing load balancing: packet-by-packet mode and flow-by-flow mode. [0003] The flow-by-flow mode is to classify the flow by analyzing the source, destination IP address and source, destination port number, and protocol classification of the data packet flow. The data packets belonging to the same flow are routed to the same link, which can ensure that they belong to the same The data packets of the flow arrive at the destination in sequence, avoiding out-of-order. Such as figure 1 As shown, when a Gigabit Ethernet (GE, Gigabit Ethernet) link is load-balanced to three 622Mbps links, data traffic enters router R1 from the GE link, ...
