| Compared with Gigabit Ethernet,10 Gigabit Ethernet has absolute advantages and characteristics.It is first reflected in the physical link,and its communication material is full-duplex optical fiber,so it has the absolute advantage in speed and transmission quality.10G Ethernet has a good inheritance of the Ethernet before,so the risk of upgrade is very low,while in the next upgrading to 40G or 100G are obvious advantages.As increasing popularity of network applications,network development is growing fast.Especially the rapid development of business applications,such as video,is very fast.With gradually extending of 10G Ethernet technologies,and rising of network capacity,the pressure of data transmission and processing is increasingly greater.It can be seen from the foreign construction 40G and 100G backbone network,the backbone network in China is in a stage of rapid development,and 10G Ethernet will become the main backbone network in a fairly long period of time.As 10G Ethernet is applicated in the large core network,and the data is transported in a high rate,the service quality assurance is important.It should pay attention to the network link test.In this paper,the 10G Ethernet tester is designed for the next generation of MAN and IP bearer network,and it is a complete test solution for carrying Ethernet voice,data and video services.This paper shows the hardware structure of the 10G Ethernet tester and descripts how it can speed uo to 10G.This paper will focus on the software design.This article introduces the composition and architecture of Qt.It also describes architecture of the client/server mode and Qt's core signal slot mechanism.This paper discusses the test protocol of network in different chapter,including BER testing and RFC2544.This paper shows the flow chat of program.Finally,the article descripts a new test protocol Y.1564 and give test method. |
