FPGA-based Ethernet service test apparatus and method

Abstract

The invention discloses an FPGA-based Ethernet service test apparatus and method. The method includes: a test terminal and a reflection terminal for service measurement are configured by a network administrator; the network administrator starts service measurement, the test terminal sends a test message based on configuration, the reflection terminal receives the test message, carries out path field replacement based on configuration instead of processing the payload of the test message, and then reflects the test message to the test terminal; the test terminal carries out frame parsing on thereceived test message returned by the reflection terminal to extract a time information field; the test terminal completes counting of message sending and receiving and completes calculation and caching of time test information; and after test time is over, the test terminal latches the test data and provides a CPU interface for the CPU reading. Therefore, the cost and test implementation difficulty of integration of functions of the test terminal and the reflection terminal for Ethernet service measurement to transmission equipment are reduced substantially and the integration of the test system is improved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to an FPGA-based Ethernet service testing device and method. Background technique [0002] With the development of the information age, data services have gradually replaced voice services as the main service carried by the transmission network. The advancement of technology has extended the application field of Ethernet from the initial local area network to the metropolitan area network and wide area network. At the same time, the growth of network services has brought enormous pressure on the network, and network performance, service quality and reliability have become the focus of attention. Therefore, network service testing technology has developed rapidly in recent years, providing an effective means for evaluating network performance. [0003] Ethernet service measurement mainly includes equipment performance test and network performance test. Both RFC2544 protoc...

AI Technical Summary

Problems solved by technology

[0004] When performing Ethernet service measurement on the live network, it is necessary to integrate the test end and reflection end functions of the Ethernet service measurement into the transmission equipment. However, because the traditional Ethernet service measurement is based on instrument testing, it is expensive and does not have existing Network testing capability
