Multi-stage software router architectures permit to overcome several limitations of single-stage software routers, allowing to expand the number of available interfaces and to increase the overall throughput. However, a multi-stage software router, despite being composed by several internal elements, must externally appear as a single device. A control protocol called DIST was defined to solve this problem from the control plane point of view for a previously proposed multi-stage architecture. In this paper, the authors tackle the same problem from the network management point of view.
