Problems solved by technology

Or throughput testing cannot be done without a test terminal
Moreover, setting up such a test environment is complicated, and there are many parts involved in locating faults. The test results are also greatly affected by the test environment such as the terminal, which is easy to waste time and reduce efficiency.
[0005] At present, in the industry, no effective method has been proposed, or it is not aware of this problem, and it is only solved by purchasing equipment

Embodiment Construction

[0029] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] Considering that the chips used for business processing and access termination are independent on a general broadband access board, and we test the capability of the service processor when we conduct a throughput test, based on the above principles, we propose a method to solve the above problems It utilizes the data loopback function provided by the DSP set chip that completes the access function on the single board, and loops the data stream on the set chip, so that the traffic sent by the test equipment SmartBits does not need to actually pass through the terminal, but only passes through the service processor to reach the receiving end. Configure a fast di...

Abstract

The invention provides a method for testing single-plate throughput performance of wideband access system, comprising the steps of: configuring downlink port and each of several user ports in a VLAN, respectively, to compose several downlink VLANs, and configuring user ports into VLAN tag-free mode; configuring uplink port and several user ports together in a VLAN to compose an uplink VLAN, different from the downlink VLANs and configuring several user port VLAN marks to make them all correspond to the uplink VLAN; configuring digital looping function in data looping parts at several user ports and testing signals returning from data looping part to the uplink port. Thus, it reduces test complexity and saves the cost of buying large numbers of terminals and raises failure locating efficiency.

Description

technical field [0001] The invention relates to the field of hardware single-board testing of a broadband access system, and more particularly relates to a method and device for testing the throughput performance of a single-board of a broadband access system. Background technique [0002] For the data loopback function, generally for the hardware single board of the broadband access system, its hardware components are mainly composed of two components, namely, the service processor and the user-side access unit. On the access unit of the function, in the face of the data loopback function provided by the service processor, its main function is to send the data packet sent by the service processor to the access unit on the user side unconditionally and reversely send it. The loopback function is used for connectivity testing. The digital processing part of the user-side access unit is generally a DSP (Digital Signal Processor, digital signal processing chip, hereinafter ref...
