Dermi (Decentralized Event Remote Method Invocation) is a peer-to-peer (P2P), decentralized event-based object middleware framework built on top of a structured Distributed HashTable based overlay network.
Jupp is a Distributed HashTable focusing on high throughput. It's main characteristics are:
1. Mechanisms for congestion control
2. O(log n) routing for arbitrary peer distributions in the ID space.
