【摘要】 未来网络的业务存在较大的不确定性,并且预计流量增长迅速,因此需要更高效地疏导流量。近几年已经研究出以OTN集群的方式实现OTN站点资源池,解决单节点大容量、多方向和快速调度的问题。本文对OTN集群系统的交叉技术进行了分析,并从硬件设计方面,介绍了一种能够满足OTN集群需求的交叉盘板卡设计方案。该方案共包含两种交叉盘,分别用于业务框和交换框,能够实现2+8模式的OTN集群。通过测试发现,板卡在配置跨框业务时能够正常工作,满足OTN集群需求。更多还原

【Abstract】 As network traffic is expected to grow rapidly in the future, it is necessary to channel traffic more efficiently. In recent years, it has been studied to implement OTN site resource pools in the form of OTN clusters to solve the problems of single node large capacity, multiple directions and fast scheduling. This article analyzes the crossover technology of the OTN cluster system, and from the aspect of hardware design, introduces a cross-disk board design that can meet the needs of the OTN cluster. The solution includes two types of cross disks, which are used for the service frame and the switch frame respectively, and can realize the 2+8 mode OTN cluster. Through testing, it is found that the board can work normally when configuring cross-frame services to meet the needs of OTN clusters.更多还原
