着重探讨了解决光突发交换网中突发数据包之间争夺链路资源引起数据丢失的丢失恢复机制,主要包括突发克隆、前向冗余、重传等机制,对这些技术的优缺点进行了比较分析,并提出了一种改进方案。
In this paper, we mainly introduce the issue of how to resolve the loss of bursts due to contending for link resource among data bursts in OBS networks, and discuss some loss recovery strategies in OBS such as burst cloning, forward redundancy and retransmission. Then, we compare their characteristics, and present an improved loss recovery mechanism.
