所谓热门技术是指一二年内能进入电信系统成为主流的技术,而且现在已经投入足够的开发资金,并受到业界的支持。最近美国《Telecommunications》杂志评出了2001年十大热门技术,它们是:超密集波分复用、先进FEC、甚高速DSL(VDSL)、自由空间光系统、弹性分组环、H.248/Megaco、基于查询薄的管理、自适应调制、喇曼放大器、流控制传输协议(SCTP)。在此,笔者根据自己对这十大热门技术的理解把它们介绍给读者。超密集波分复用(UltraDWDM)
The so-called hot technology refers to one or two years to enter the telecommunications system into the mainstream technology, and now has invested enough development funds, and by the industry’s support. Recently, the United States named “Top Ten Popular Technologies in 2001” by Telecommunications magazine. They are: ultra-dense wavelength division multiplexing, advanced FEC, very high speed DSL (VDSL), free space optical system, flexible packet ring, H.248 / Megaco , Query-based Management, Adaptive Modulation, Raman Amplifier, Stream Control Transmission Protocol (SCTP). Here, the author based on their understanding of these top ten popular technology to introduce them to readers. Ultra Dense Wavelength Division Multiplexing (UltraDWDM)
