ATM技术的发展并非一帆风顺。从一开始,其他技术就联合起来向ATM挑战,首先是LAN交换,然后是IP交换,接着是千兆以太网。现在,ATM技术不仅成功地立足,而且逐渐繁荣起来。 当用户发现某些应用必须使用ATM所具有的一些特性时,ATM成功地打破了有些人关于ATM即将衰落的预言。 用户普遍认为,ATM技术是最具升 The development of ATM technology is not easy. From the very beginning, other technologies have joined forces to challenge ATM, starting with LAN switching, then IP switching, followed by Gigabit Ethernet. Now, not only has the ATM technology successfully gained a foothold, it has also boomed. When users find that certain applications must use some of the features of ATM, ATM has successfully broken some people’s prediction that ATM is about to decline. Users generally believe that ATM technology is the most upgraded
