The job at Accton is to design test cases, execute designed cases, and writton. The job at Accton is to design test cases, execute designed cases, and write down all the detailed testing procedures. The purpose of the regular meetinge down all the detailed testing procedures. The purpose of the regular meetings at NBL for this project is to work out possible combinations of features for ts at NBL for this project is to work out possible combinations of features for testing, purpose for each test case, and possible testing procedures. That is, befesting, purpose for each test case, and possible testing procedures. That is, before fulfilling testing procedures at Accton, we should think how to create test ore fulfilling testing procedures at Accton, we should think how to create test cases in our regular meetings.

Before the teTP) conformance of the Accton L3 switch. Before the testing, I thought the pass ratio should be 100% because Ssting, I thought the pass ratio should be 100% because STP is a classical protocol. However, the test results shoTP is a classical protocol. However, the test results shown many failures in the timer-related test cases. I found wn many failures in the timer-related test cases. I found the timer of the DUT is very inaccurate even the configuthe timer of the DUT is very inaccurate even the configured time is very short. The inaccurate timer would affect red time is very short. The inaccurate timer would affect many operations of STP, such as MAC entry expiration ,many operations of STP, such as MAC entry expiration , port state transition and topology change.

However, a content deploying servers in several ISP networks. However, a content delivery network acts as a third party to deliver content for delivery network acts as a third party to deliver content for various content providers into ISPs networks. In this paper, we various content providers into ISPs networks. In this paper, we introduce the evolution of Internet content delivery and evaluate introduce the evolution of Internet content delivery and evaluate the performance of CDN. In our evaluation, we find that CDN the performance of CDN. In our evaluation, we find that CDN saves more bandwidth consumption and distribution time than saves more bandwidth consumption and distribution time than traditional distribution alternatives, has shorter user-perceived traditional distribution alternatives, has shorter user-perceived latency than centralized hosting, and improves the delivery latency than centralized hosting, and improves the delivery quality of streaming media.quality of streaming media.
