Test items
The performance indicators are tested using a dedicated Ethernet test instrument, and the test results of these performance indicators can also evaluate whether the LAN system meets the acceptance requirements. From GBT21671-2008 "Ethernet-based LAN System Acceptance Evaluation Specification", it can be understood that LAN can also judge performance by measuring performance indicators such as network throughput, transmission delay, and packet loss rate. The Ethernet tester is a rugged test platform suitable for field use. It has a complete Ethernet test function, dual optical ports and dual electrical ports, Ethernet service interface module, HST-3000 supports multiple data stream tests. Including 10/100/1000M Ethernet link traffic generation and troubleshooting, it can test electrical and optical port links up to 1Gbit/s. Due to the limitation of various conditions in the acceptance inspection, point-to-point or routing network testing can be supported for routine testing of switches.
The problem
The overall characteristics of modern test instruments are high reliability, high performance and high applicability. Therefore, the gap between domestic test products and foreign products is reflected in this aspect. Although some domestic testing equipment is close to the international advanced level in certain performance indicators, there are generally few products with comprehensive equipment performance indicators that meet international standards. In addition, most of the domestic test instruments are common specifications, which cannot meet the test work in some special environments. Low-level automated testing is also a common problem. [3]
Switch test technology
Nowadays, switches put forward new requirements on the performance of switches based on application requirements. There have been new developments in comprehensive network services, security, and intelligence. Protocol testing is a basic switch testing technology. The network protocol is to improve the efficiency of testing and the effectiveness of communication to ensure the rules of communication. In the era of increasing network communication, network protocols are also indispensable. The basic requirements of network protocols are correct functions, good interoperability and superior performance. The initial prototype of protocol testing is software testing, and the main categories are black box testing, white box testing and gray box testing.
