光分组交换机提供了未来计算机通信和基于信元的电信网络所需的高速、数据速率和格式透明性以及灵活性。本文综述了目前最先进的光子分组交换的实验研究进展，重点介绍了全光导波系统。术语全光意味着从源到目的地的分组的数据部分保持光学格式。虽然数据仍然是全光的，但已经使用光学和光电子技术来处理基于极其简单的路由协议的分组路由功能。概述了全光光子分组交换的设计问题，并与电子分组交换的实现进行了对比。已经实验实现的低级别功能包括路由、争用解决、同步和报头重新生成。将回顾系统级演示，包括集中式光子交换和分布式全光多跳网络。>；
Photonic packet switches offer high speed, data rate and format transparency, and flexibility required by future computer communications and cell-based telecommunications networks. In this paper, we review experimental progress in state-of-the-art photonic packet switches with an emphasis on all-optical guided-wave systems. The term all-optical implies that the data portion of a packet remains in optical format from the source to the destination. While the data remain all-optical, both optical and optoelectronic techniques have been used to process packet routing functions based on extremely simple routing protocols. An overview of the design issues for all-optical photonic packet switching is given and contrasted with electronic packet switch implementations. Low-level functions that have been experimentally implemented include routing, contention resolution, synchronization, and header regeneration. System level demonstrations, including centralized photonic switching and distributed all-optical multihop networks, will be reviewed. >
