Recent work such as Tapestry, Pastry, Chord and CAN provide efficient location
utilities in the form of overlay infrastructures. These systems treat nodes
as if they possessed uniform resources, such as network bandwidth and connectivity.
In this paper, we propose a systemic design for a secondaryoverlay of super-nodes
which can be used to deliver messages directly to the destination's local
network, thus improving route efficiency. We demonstrate the potential performance
benefits by proposing a name mapping scheme for a Tapestry-Tapestry secondary
overlay, and show preliminary simulation results demonstrating significant
routing performance improvement.
