The OceanStore Project Paper Abstract Brocade: Landmark Routing on Overlay Networks Ben Y. Zhao, Yitao Duan, Ling Huang, Anthony Joseph and John Kubiatowicz. Appears in Proceedings of the First International Workshop on Peer-to-Peer Systems (IPTPS 2002),

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 secondary overlay 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.
