Embodiment Construction

[0096] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0097] Multicast is a kind of 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 the 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 data volumes on small bandwidth links. For small channels in large bandwidth, small channels are the reduction of large bandwidth traffic. Therefore, multicast and load splitting are ...

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 is not limited to, the field of communication technology, in particular to a bandwidth measurement method, device and system. Background technique [0002] Bandwidth measurement can better feedback the quality of the line, which is the data index that users are most concerned about. Traditional link bandwidth measurement methods are required to be performed in a scenario where the uplink and downlink bandwidths are consistent. [0003] In current business applications, on the one hand, there are generally scenarios where the uplink and downlink bandwidths are asymmetric; on the other hand, with the increase in the large bandwidth requirements of communication equipment, the current uplink port rate requirement of communication equipment has increased to 100GE, which is increasingly Many manufacturers upgrade their equipment to the uplink port with 100GE capability. However, due to cost and technical limitations, although...
