Embodiment 1

[0079] When encapsulating user packets in the QinQ format, a double-layer tag is usually used to mark an enterprise user in the MAN. The outer tag represents a certain enterprise, and the inner tag represents different services in the enterprise. The specific encapsulation format of QinQ is shown in Table 1. in,

Abstract

The invention provides an end-to-end flux measurement method, comprising: a sending exchange receives a data message of a pending measurement user, and acquires the test message at a test port, wherein the test message takes with an identification of the pending measurement user; when the bandwidth occupied by the data message of the pending measurement user is less than an appointed speed of a pending measurement flux, the exchange transmits the data message and test message of the pending measurement user at an output port to make the total bandwidth occupied by the data message and the test message equal to the appointed speed of a pending measurement flux and to make the test message transmit in a priority lower than that of the data message; a receiving exchange receives and accounts the total bandwidth occupied by the data message and the test message of the pending measurement user at an input port based on the identification of the pending measurement user as an end to end actual flux bandwidth. The invention further provides a sending exchange and a receiving exchange for an end to end flux measurement. The invention can achieve an end to end flux bandwidth measurement in a condition without breaking the user data message.

Description

technical field [0001] The invention relates to the measurement technology of network parameters, in particular to an end-to-end flux measurement method and equipment. Background technique [0002] Ethernet has developed rapidly due to its low cost, high bandwidth, and easy deployment. With the rapid development of the Internet, many new services have emerged, such as VOIP, BTV, VOD and so on. The interconnection business of enterprise customers is migrating from the traditional Frame Relay / Private line to Ethernet E-LINE, E-LAN, etc., and various business departments and external customers in the enterprise are increasingly relying on the network to complete daily business processing And communication, any network or service interruption or even performance degradation will have a serious impact on the enterprise business. [0003] In the operator's network, the IP network is shared by many users. However, not all users will use the bandwidth of the IP network online at ...
