RESUMO
The transport layer structure of the Internet is moving towards a model of highspeed routers interconnected by intelligent optical core networks. A consensus has been reached on wavelength division multiplexing (WDM) as the way to increase the transmission capacity. However there are few proposals for distributed control planes under dynamic Quality of Service (QoS) constraints for large networks. In this context, resources availability must be frequently distributed and updated across the network; and flooding may no longer be the best strategy for information dissemination. This work proposes and assesses an overlay structure based on distributed hash tables (DHT) for information indexing over bi-dimensional virtual coordinated spaces. By adding long-distance interconnections to Content-Addressable Networks (CAN), the resulting small-world effect can reduce the number of hops per resource search. Analytical results indicate significant reduction in management traffic over the physical layer of large networks without penalizing to much the inserted delay
