TANG Jian jun, JI Yue feng. Study on optical burst switching based on next-generation optical Internet[J]. 2003,(1):5-8. DOI: 10.13756/j.gtxyj.2003.01.002.
This article discusses design issues related to a new switching paradigm called optical burst switching (OBS). And then it describes how OBS can be applied to the next generation optical Internet
and in particular how offset times and delayed reservation(DR) can help avoiding the use of optical buffer
and support quality of service (QoS) at the WDM layer.
