什么是ＤＰＴ ＤＰＴ是新一代的，采用优化的动态分给（或称包）的传送技术。ＤＰＴ吸收当前ＳＯＮＥＴ（同步光纤网）／ＳＤＨ的优点，克服其缺点，把充分利用带宽，ＩＰ的丰富功能，以及光环自愈等有效地集合起来，在现有的光纤网络上提供最经济与有效的服务。 采用分组环解决方案充分利用带宽复用功能，如在大的传输信道上的统计复用，以及空间再利用技术等。带宽可由１５５Ｍｂ／ｓ扩展到１０Ｇｂ／ｓ以上。 比ＴＤＭ的ＳＯＮＥＴ／ＳＤＨ设备和分／插队复用器（ＡＤＭ）等组网络经济便宜。 新的即插即用的综合网络管理功能，大大节省了传统的交换和传输网络管配置及管理费用，并大大提高了效率。
What is DPT? DPT is the next generation of transmission technology optimized for dynamic distribution (or packet). DPT absorbs the advantages of current SONET (Synchronous Optical Network) / SDH and overcame its shortcomings by effectively bringing together bandwidth-rich features of IP and optical ring self-healing to provide the most cost-effective and efficient over existing fiber optic networks Service The use of packet ring solution to take full advantage of bandwidth multiplexing functions, such as statistics on the large transmission channel multiplexing, as well as space reuse technology. The bandwidth can be expanded from 155Mb / s to above 10Gb / s. Networking is cheaper than TDM’s SONET / SDH equipment and branch / tandem multiplexers (ADMs). The new plug-and-play integrated network management features greatly save the traditional switching and transmission network configuration and management costs, and greatly improve the efficiency.
