Problems solved by technology

However, the bandwidth tested in this way is usually lower than the bandwidth of the user contract. This is because FTP is an application layer protocol, including IP, Ethernet, and ATM protocol overhead;
Therefore, the test bandwidth does not match the actual bandwidth, making users doubt the integrity of the operator

Embodiment Construction

[0029] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0030] Such as figure 1 Shown, diagram is the structure of the bandwidth testing system preferred embodiment of ATM ELAN business of the present invention, comprises:

[0031] The file monitoring unit 101 is used to monitor the Ethernet packet size corresponding to the test file application package, and the test file transfer rate;

[0032] ATM ELAN protocol overhead analysis calculation unit 102, for calculating the protocol overhead of the ATMELAN of said ether packet according to the Ethernet packet size and the test file transfer rate that file monitoring unit 101 monitors to obtain;

[0033] The comprehensive analysis unit 103 is used to calculate the bandwidth of the ATM ELAN as the sum of the test file transfer rate and the ATM ELAN protocol overhead.

[0034] Wherein, the ATM ELAN protoco...

Abstract

This invention discloses a broadband test method and a system for ELAN service of abnormal transmission mode(ATM) including: a file monitor unit monitors size of an Ether packet corresponding to an applied packet of the test file and tests its transmission rate, an analysis and computation unit for spending of the ATM ELAN protocol computes the ATM ELAN protocol spending of the Ether packet basedon the size of the packet tested by the monitor unit and the transmission rate of the test file and an integrated analysis unit is used in computing that the ATM ELAN broadband is the sum of the rateand the protocol spending.

Description

technical field [0001] The invention relates to a bandwidth testing technology, in particular to a testing method for confirming bandwidth provided to a user when an asynchronous transfer mode (ATM) local area network emulation (ELAN, Emulation of LAN) service is opened. Background technique [0002] With the popularization of the Internet Protocol (IP) and the desktop trend of Ethernet (Ethernet), the IP service of Ethernet access carried by the ATM network can provide users with high security and high reliability guarantees. Important customers with quality and bandwidth assurance requirements. Therefore, how to prove to the user that the circuit bandwidth provided by the operator complies with the service level agreement (SLA) will be an important issue when the user service is opened, which is related to the service brand of the operator and the vital interests of the user. [0003] Generally, when the ATM ELAN service is opened, the smoothness of the ATM ELAN circuit i...
