摘要：Optical burst switching (OBS) is an emerging solution to achieve all-optical WDM networks. It combines the advantages of optical circuit switching and optical packet switching. In this paper, we discussed the OBS network node structure and characteristics. In OBS networks, the basic switching entity is a burst. prior to transmitting a burst, a control packet is created and immediately sent toward the destination in order to set up a buffer-less optical path for its corresponding burst. After an offset delay time, the data burst is transmitted without waiting for an acknowledgement from the destination node. The optical path exists only for the duration of a burst.
