Problems solved by technology

[0012] Since multi-frame generators and detectors are more expensive than single-frame generators and detectors, and multi-frame generators and detectors are newly launched products, most companies have already purchased single-frame generators and detectors. Generators and detectors lead to repeated purchases, increasing the cost of implementing fluidic functional testing

Embodiment Construction

[0026] The core of the present invention is to realize the connection of the test process by cascading Ethernet ports sequentially, then configure according to the needs of the test, and carry out the corresponding flow control test. The cost of the flow control test on the Ethernet port.

[0027] The device of the present invention includes in the specific implementation process:

[0028] The frame generator, the frame detector and the cross function module, the frame generator and the frame detector communicate with the cross function module through a group of Ethernet ports to be tested, and the group of Ethernet ports to be tested is passed through the cross function module level In other words, the output of the upper-level Ethernet port on the Ethernet single board is used as the input of the lower-level Ethernet port, and each Ethernet port is cascaded in turn; the output of the frame generator is used as a group of cascaded The input of the first Ethernet port among t...

Abstract

An equipment and method to achieve fluidic testing, that is: cascade a group of untested Ethernet ports by the overlapping, the output of the frame generator as input of the first Ethernet port in a group of cascade Ethernet port, the last Ethernet port output in a group of cascade Ethernet port as the input of the frame generator; then, processes the corresponding configure and fluidic testing based on the untested Ethernet port. The invention can achieve the fluidic function testing for all the ports of the Ethernet veneer and not reconnect the exterior line of the Ethernet veneer, thereby improve the testing efficiency and decrease the testing cost.

Description

technical field [0001] The invention relates to testing technology in the field of communication technology, in particular to a flow control testing technology used in communication network equipment. Background technique [0002] At present, Ethernet technology has been widely used, major operators have basically completed the construction of their own backbone transmission network, MAN (Metropolitan Area Network) has become the focus of competition among operators, with the continuous development and improvement of Ethernet technology , Ethernet technology has matured. The Ethernet single board is one of the important components of the existing metropolitan area network equipment. It is mainly used to solve telecom application fields such as Ethernet service access, aggregation, bandwidth management, and Ethernet service Layer 2 switching. [0003] Tests for Ethernet boards include auto-negotiation tests and flow control function tests. Among them, the basic principles o...
