多层异构软件定义光网络协同互联方法

Method of collaborative interconnection in multi-layer heterogeneous SDON

针对融合网络技术快速发展导致网络环境异构化趋势明显这一现象,在软件定义光网络(SDON)的基础上,提出了一种多层异构网络协同互联架构,基于该架构对域内域间建路进行了具体说明,并对OpenFlow协议进行了相应的扩展,以实现多层异构SDON协同互联。

With the rapid development of converged network technology, environment of Internet network shows an obvious trend to be heterogeneous, in order to solve this problem, this paper proposes a cooperative interconnection architecture including multi-layer heterogeneous network and multi-controller based on the software defined optical network （SDON）, and describes the intra-domain road construction process and the inter-domain road construction process, further more, the OpenFlow protocol has been extended based on this architecture to achieve cooperative interconnection in multi-layer heterogeneous SDON.
