多波长光标记交换中一种新的多波长-时间编码法(英文)

A Novel Multiwavelength-time Label-coding Scheme in Multiwavelength Label Switching

首先介绍了多波长光标记分组交换的基本原理 ,并针对多波长光标记分组交换中的标记头编码法 ,提出了一种新的多波长 时间编码法 ,这种编码法充分利用了波长和时间两种自由度 ,大大增加了编码数量 ,提高了编码效率 .最后 ,设计了实现这种编码的发射机和接受装置 .

In multi-wavelength label switching, a case of using K bit-long label and W different wavelengths can obtain WK unique labels at most. Here a novel label-coding scheme was put forward, which can produce more labels than before, for an example, if using 2 bit-long label and 2 different wavelengths, it can get 9 different labels, instead of 4 different labels using the old coding method proposed before. At last, the design of the transmitter and receiver are given in detail.
