基于HCM的可扩展路由器体系结构MER

本文提出了基于层次化协同模型的多维可扩展路由器MER。参考Open Router路由器模型,利用层次化协同模型实现了独立于数据层的控制平台CSP,奠定了开放控制的基础;基于功能插件和抽象插件构造了基于插件的路由器抽象层PRA,分离了控制与转发平面,支持路由器转发平面功能的动态扩展;并举例说明了MER中高效的网络应用控制路由选择机制,体现了直接控制原理,有助于设计更为复杂的控制策略。模拟结果表明,MER具有良好的扩展性,支持网络应用直接控制,为控制平面智能化奠定基础。

Multidimensional Extensible Router; coordination service point; router adapter

A Multidimensional Extensible Router based on hierarchical coordination model is proposed. Referring to OpenRouter model, we implement coordination service point by applying the hierarchical coordination model to the transceiver of messages, which facilitates open control. We build plugins-based router adapters based on symbol plugins and functional plugins, which separates control plane from the data plane and supports the dynamical extensibility of router functions. We evaluate MER’s responsiveness and extensibility when it is applied to an enterprise network and the CERNET topologies. The experiments show that MER is resilient to component failures, and its responsiveness for intra-domain routing control is sufficiently scalable to handling a thousand nodes, and enables direct control, which helps to realize intelligent control.
