本文主要介绍万兆以太网的核心技术以及在新领域中的研究。相对于传统以太网,万 兆以太网自身有其独特的特点,而且更是突破了传统以太网的应用领域,已扩展到城域网甚至广域网中。本文最后还讨论了利用LAPS 技术使城域网和广域网完全融合的可行性。 关键字: 万兆以太网;LAN; WAN; LAPS; XGMII Abstract: This paper presents the key technical of 10 gigabit Ethernet and it’s application in new ields. In Comparison with 10M/100M/1000M Ethernet, the 10G Ethernet has some outstanding haracteristics. And 10G Ethernet has begun to move Ethernet from the Local Area Network to etro/Wide Area Network. At last, we discuss the interlinkage between LAN and WAN use by APS technical. Key words: 10G_Ethernet; LAN; WAN; LAPS; XGMII
