光突发交换网络中的突发分组组装策略

Burst Packet Assembly Policies for Optical Burst Switching Network

光突发交换(OBS)技术集成光电路交换和光分组交换的优势,能满足现有大容量、高速率的多媒体信息交换与传输,将成为下一代光IP骨干网的核心技术。本文详细论述了OBS网络中的关键技术———突发分组的组装技术的各种策略与实现方式,指出具有良好QoS保证又可降低可操控性的突发组装策略将成为最佳选择。

Optical burst switching (OBS) technology integrates the advantages of optical circuit switching and optical packet switching into one which can satisfy the need of switching and transmitting of multimedia information with large volume and high rate, it will be the core technology of next IP backbone network. This paper describes some key technologies of OBS network, namely some assembly policies and realization methods of burst packets at OBS network edge, in conclusion the burst assembly policy with better QoS and easy practicability will be the best one.
