摘要

面对巨大的P2P流量挑战,网络编码在提高系统效率方面显示出巨大的优势。本文提出了一种将网络编码集成到无源光网络中并与现有以太网无源光网络兼容的解决方案NC-PON。为了提高效率,将软件定义技术与网络编码相结合,提出了一种基于网络编码的软件定义无源光网络(snc - pon),以优化不同olt下的P2P流量。snc - pon的核心思想是灵活改变olt和onu之间的owner-member关系,实现最大的流量效益。实验平台和仿真结果表明,该体系结构高效、具有网络灵活性。

Experimental evaluation of software defined passive optical network with network coding
Facing with the huge P2P traffic challenge, network coding shows great advantages in improving system efficiency. This paper proposed a solution to integrate network coding into passive optical networks and compatible with the existing Ethernet passive optical network named NC-PON. To increase more efficiency, a software defined passive optical networks with network coding (SDNC-PON), which combines the software defined technology and network coding, was proposed to optimize the P2P traffic under different OLTs. The core idea of SDNC-PON is to change the owner-member relationship between OLTs and ONUs flexibly to achieve the maximum traffic benefit. The results of experimental platform and the simulations indicated that the proposed architecture is efficient and with network flexibility.
