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

Embodiment Construction

[0036] The invention integrates the Ethernet test protocol function into the transmission equipment, wherein the FPGA is used as a message sending and receiving engine, the CPU is responsible for main control and forwarding, and the upper computer implements network management configuration. The present invention is implemented based on FPGA, and realizes the message sending and receiving engine, that is, the main function of the protocol. The functions of the test end and the reflection end can be realized at the same time, wherein the test end sends test packets in the sending direction according to the configured frame length, frame interval, frame header content and test duration; at this time, the remote end acts as the reflection end, and the reflection end changes the path according to the configuration After receiving the information (without modifying the payload content), the test message is bounced back to the test terminal; the test terminal resolves the bounced tes...

Abstract

The invention discloses an FPGA-based Ethernet service testing device and method. The method includes: a network manager configures a test terminal and a reflection terminal for service measurement; the network management starts service measurement, and the test terminal starts to send test messages according to the configuration. After receiving the test message, do not process the test message payload, only replace the path field according to the configuration, and then reflect the test message back to the test end; the test end performs frame analysis on the received test message looped back from the reflection end , to extract the time information field; the test end completes the counting of sent and received messages, and at the same time completes the calculation and buffering of time test information; after the test duration is reached, the test end latches the test data and provides a CPU interface for the CPU to read. The invention greatly reduces the cost of integrating the functions of the test end and reflection end of the Ethernet service measurement into the transmission equipment and the difficulty of test implementation, and improves the integration degree of the test system.

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...
