ATM加速了全球数据、语音和视频传输。它应用在各个领域,从专有网络、电信网络到Internet。尽管ATM可传输多媒体应用,但ATM交换机厂商仍不得不考虑其它技术,如IP和千兆以太网技术。业界应尽快统一在ATM交换机中增加JP功能的标准。人们已公认IP网络效率高且价格低,而多数专家认为ATM是扩展性强且灵活的技术,ATM网络的扩展无需替换骨干网系统。ATM和IP网络并不适干各种网络环境,因而大多数交换机厂商希望在ATM交换机中加入IP ATM accelerates global data, voice and video transmission. It is used in various fields, from proprietary networks, telecommunications networks to the Internet. Although ATM can transmit multimedia applications, ATM switch manufacturers still have to consider other technologies, such as IP and Gigabit Ethernet technology. The industry should unify the standard that adds JP function in ATM switchboard as soon as possible. It has been recognized that IP networks are highly efficient and inexpensive, and most experts consider ATM as an extensible and flexible technology that does not require the replacement of a backbone network for ATM network expansion. ATM and IP network is not suitable for a variety of network environments, so most switch manufacturers want to add IP in the ATM switch
