Ziguang Guoxin (002049) announced on Wednesday evening that the company intends to invest in Beijing to set up a wholly-owned subsidiary Ziguang Guoxin Microelectronics Co., Ltd. (tentative name) with a registered capital of 100 million yuan.
The new company's business scope is integrated circuit design, packaging, testing, sales; technology development, technology transfer, technical consulting, technical services; import and export of goods, technology import and export, agent import and export.
Ziguang Guoxin said that the company's foreign investment to set up a wholly-owned subsidiary will further expand the company's integrated circuit design business, enhance the company's core competitiveness and profitability, and promote the company's sustained and rapid development.
The problem
Throughput is an important indicator of Ethernet testing. Many engineers believe that the Ethernet switching throughput should be its line rate, that is, no packet loss can occur at 100% traffic, and that it is illegal for the Ethernet frame interval IFG to be less than 96 bits. However, in the Ethernet switching throughput and packet loss rate test, a small amount of packet loss occurs in the long-term error test under the line speed condition. The reason is the cross-clock domain architecture of the Ethernet.
With the rapid development and application of industrial Ethernet technology, a large number of network problems have appeared along with it. According to statistics provided by Siemens, the network communication failure rate accounts for more than 70%, and the network equipment failure rate is less than 30%. After a network failure causes the system to shut down, the time required for fault diagnosis and location accounts for more than 80% of the total system downtime, while maintenance measures take up less than 20%. Therefore, real-time monitoring and analysis of network traffic is a major problem in the development and application of industrial Ethernet. Real-time monitoring and analysis of industrial Ethernet network traffic and timely detection and location of network problems play a vital role in improving the stable operation of the entire system. .
