Problems solved by technology

The packets after 747 are the third stage. At this time, there are not enough tokens in the token bucket to send a packet, and the packet queue is full, so it passes through at an average rate, but keeps losing packets
This makes it difficult to apply the existing end-to-end bottleneck bandwidth measurement technology to the measurement of the access network, which has become a major problem in the measurement of the access network

Embodiment Construction

[0088] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0089] see Figure 7 , the present invention is a measurement system of bottleneck bandwidth and remaining bandwidth under the token bucket rate-limited network path, the system consists of a sending device at the sending end for sending probe packets, a receiving device at the receiving end for receiving probe packets, and related It is composed of an analysis device for processing measurement data, and the connection between the sending end and the receiving end adopts the data connection of UDP protocol. Among them, the sending device, the receiving device, and the analyzing device are solid-line boxes, indicating that these three devices are basic devices and indispensable. The two control devices are dotted boxes, indicating that in a simple implementation, ...

Abstract

This invention relates to measure method and system for bottle wide and remain wide band in the label barrel speed limit network path, wherein, the method comprises the following steps: establishing send end and receive end for data interacting; firstly detecting and judging whether the linkage is label speed limit network path; if yes, then computing linkage each label parameters, bottle and remain wide band; if not adopting traditional method to measure and compute the bottle wide band and remain wide band. The invention is free of label speed limited.

Description

technical field [0001] The present invention relates to a method and system for active bandwidth measurement in the field of network measurement, to be precise, relates to a method and system for measuring bottleneck bandwidth and remaining bandwidth under token bucket rate-limited network paths, and belongs to the bandwidth measurement technology of the Internet field. Background technique [0002] Each path in the network is usually connected by several physical links with different bandwidths. Therefore, the bottleneck bandwidth of a network path refers to the physical bandwidth of the link path with the narrowest bandwidth on the path. Maximum transfer capacity when there is no other background traffic. At present, the end-to-end bottleneck bandwidth measurement method is mainly based on the packet pair (Packet Pair) technology and the data packet train (Packet Train) technology. A brief introduction to it is given below. [0003] A data packet pair refers to two equa...
