It executes read downs on an old database snapshot; transactions accessing objects at their own level manipulate the most recently committed database, and are synchronized using weak and strong locks, somewhat like strict 2PL. At regular intervals, known as the version period, the old snapshot

Future: Integrated International Policiesem in database systems is our motivation. We introduce a new queueing theoretic model, the MIMO model, that incorporates burstiness in the sending side and busy periods in the receiving side. Based on simulation results derived from this model, we show that the buffer requirements from M/M/1/N queues are too optimistic.
