中文摘要:

在最近的年里,因为它的高带宽能力, 10 个 Gbit/s 以太网被动光网络(10G EPON ) 一直在获得可观的兴趣。从 1 Gbit/s 保证光滑的转变到 10 Gbit/s 设备并且避免一项重要一次性的投资进如此的一个费用敏感的市场, gigabit 以太网被动光网络(GEPON ) 的共存和 10G EPON 系统是必要的。在这篇文章,共存系统建筑学和一个新奇带宽分配算法为共存 EPON (WOCE-DBA ) 把优化重量的动态带宽称为分配因为系统被建议。这个算法能保证在不同光网络联合起来之中分享的公平带宽(ONU ) 得到的模拟结果表演组织,没有忽略 inter-ONU 和 intra-ONU 公平。最重要地,它能灵活地适应系统作文变化并且保存需要修改从 GEPON 在移植进程期间安排机制到 10G EPON 的带宽的努力。

英文摘要:

In recent years, 10 Gbit/s Ethemet passive optical networks (10G EPON) have been gaining considerable interests because of its high bandwidth capability. To ensure smooth transition from 1 Gbit/s to 10 Gbit/s equipment and to avoid a significant one-time investment into such a cost-sensitive market, coexistence of gigabit Ethernet passive optical networks (GEPON) and 10G EPON system are necessary. In this article, coexistence system architecture and a novel bandwidth allocation algorithm called weight-optimized dynamic bandwidth allocation for coexistence EPON (WOCE-DBA) for the system is proposed. The simulation results show that this algorithm can guarantee fair bandwidth sharing among different optical network unit (ONU) groups, without ignoring the inter-ONU and intra-ONU fairness. Most importantly, it can flexibly adapt to the system composition variations and save efforts needed to modify the bandwidth scheduling mechanism during the migration process from GEPON to 10G EPON.
