Embodiment Construction

[0096] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0097] Multicast is a point-to-multipoint communication, which can make a data packet of the multicast source be copied into multiple data packets on the network, so as to achieve the amplification of traffic. Therefore, the multicast technology can be regarded as the data packet amplifier. Load sharing is to divide a large channel into multiple small channels to complete the transmission of large amounts of data on small bandwidth links. For small channels in large bandwidth, small channels are the reduction of large bandwidth traffic. Therefore, multicast and load sharing ...

Abstract

The invention discloses a bandwidth measurement method, device and system. The method comprises the following steps: amplifying the flow of test flow to exceed the receiving ability Rm of a receiving pipeline by a receiving terminal, outputting the amplified test flow to a business receiving pipeline, and using the receiving ability Rm as a receiving bandwidth R, wherein the test flow is sent by a transmitting terminal through a business transmitting pipeline. By adoption of the technical scheme provided by the invention, the bandwidth measurement of a large-capacity asymmetric link is realized, and the cost of link measurement is reduced while the equipment ability is improved.

Description

technical field [0001] The present invention relates to but not limited to the technical field of communication, in particular to a bandwidth measurement method, device and system. Background technique [0002] Bandwidth measurement can better feed back the quality of the line, and is the data index that users care most about. Traditional link bandwidth measurement methods are required to be performed in a scenario where the uplink and downlink bandwidths are consistent. [0003] In the current business applications, on the one hand, there are generally scenarios where the uplink and downlink bandwidths are asymmetrical; Many manufacturers have upgraded their devices to have 100GE uplink ports. However, due to cost and technical limitations, although the uplink ports have 100GE throughput, it is still impossible to measure the link bandwidth of 100GE ports. [0004] Such as figure 1 As shown, device A and device B are schematic diagrams of two typical communication device...
