Edge-Reconfigurable Optical Networks (ERONs): Rationale, Network Design, and Evaluation

To bridge the gap between the current practice of setting up expensive, dedicated, lightpath connections (i.e., Static topologies), and the distant future vision of inexpensive access to dynamically switched end-to-end lightpaths, the authors propose a medium term solution in the form of Edge-Reconfigurable Optical Networks (ERONs). An ERON is an overlay-control network created by installing readily available MEMS optical switches, and implementing a GMPLS control plane at sites interconnected by static lightpaths. The switches and control software are deployed at the edge of the network and operated by the organization-user (i.e., outside the network provider's control), hence the term "Edge-reconfigurable".
