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.
