STUBcast - efficient support for concurrency control in broadcast-based asymmetric communication environment
Yan Qun Huang, Yann-Hang Lee · 2002
Observing that it is impractical to use traditional methods to control concurrency in a broadcast-based asymmetric communication environment, we introduce a concurrency control protocol designed for broadcast-based transaction processing called STUBcast (Server Timestamp and Update Broadcast Supported Concurrency). STUBcast supports two new correctness criteria proposed - single serializability and local serializability. These criteria are weaker than global serializability but are practical and easier to achieve in a broadcast environment. This article also shows some simulation results. These results suggest that STUBcast could be very efficient in a realistic application environment.
