A Gossip-based Hybrid Overlay for Content-based Publish/Subscribe

Fatemeh Rahimian Šarūnas Girdzijauskas Amir H. Payberah Seif Haridi

Performance evaluations:

 Skype churn trace: obtained from monitoring nodes: 4,000, Duration of monitoring: 1month, beginning September 12, 2005  Random subscriptions over one attribute

Current State-of-the-art Solutions:

High delivery latency

High relay overhead No delivery guarantees Unbalanced load on the nodes High subscription maintenance cost

The Key Design Principles of Vinifera

The use of order preserving hashing to enable routing towards ranges.

The utilization of a showering technique for routing towards ranges for subscription installation. Each node sends its subscription along the path towards the rendezvous nodes for one attribute.

The aggregation of the subscription requests along the routing path, and exploitation of a

clusterization technique that connects together nodes that exhibit similar subscriptions.

The events are delivered to the subscribers along the reverse routing paths.

The use of a novel load balancing technique, in order to deal with non-uniform subscriptions.
