DINPeer: An Optimized P2P Communication Network for Advanced Collaborative Environments

In this paper, we propose DINPeer to support both collaborative visualization and collaborative computing by overcoming limitations in current collaborative tools and peer-to-peer (P2P) overlay systems. DINPeer exploits a spiral-ring method to discover an inner ring with relative largest bandwidth to form a DINloop (Data-In-Network loop). DINPeer further integrates DINloop with P2P overlay network. The key features of DINPeer include using DINloop to replace a multicast rendezvous point and turning DINloop into a cache to achieve application data persistency. DINPeer improves current collaborative tools by providing application-level multicast, facilitating synchronous and asynchronous collaborations, and supporting the new strategy for divisible load computing. Simulations show that DINPeer improves synchronous and asynchronous collaborations. Furthermore, DINPeer reduces load completion time in divisible load computing scenario in collaborative computing.
