Abstract

We propose a novel Internet Exchange (IX) architecture, namely OSN-IX, which adopts an overlaid-star network (OSN) as an IX. OSN can be considered as a "distributed" switch, which combines the advantages of the network and switch. Compared to other IX architectures, e.g., LAN-based IX, MPLS IX, Photonic IX, etc., OSN-IX has good properties of scalability, resilience, and widely distributed access points. Particularly, for the first time, OSN-IX introduces traffic engineering (TE) into the IX world. Based on the TE framework we developed for OSN-IX, OSN-IX can provide optimized dynamic inter-ISP (Internet Service Provider) routing while requiring no change, hardware or software, on existing traditional IP/MPLS routers. We have shown by simulation that our TE framework outperforms several existing inter-AS TE schemes.
OSN-IX:一种新的基于重叠星型网络的互联网交换(IX)架构
我们提出了一种新的互联网交换(IX)架构,即OSN-IX,它采用重叠星型网络(OSN)作为IX。OSN可以看作是一个“分布式”交换机,它结合了网络和交换机的优点。与基于lan的IX、MPLS IX、Photonic IX等其他IX架构相比,OSN-IX具有良好的可扩展性、弹性和广泛分布的接入点。特别是,OSN-IX首次将流量工程(traffic engineering, TE)引入了IX世界。基于我们为OSN-IX开发的TE框架,OSN-IX可以提供优化的动态isp间(互联网服务提供商)路由,而无需对现有的传统IP/MPLS路由器进行硬件或软件更改。我们通过仿真表明,我们的TE框架优于几种现有的as间TE方案。
