“…Most work in the multidatabase systems (MDBSs) area has focused on the issues of transaction management and concurrency control (e.g., [3,4,7,16]). It is difficult to implement traditional transaction management techniques in an MDBS due to the heterogeneity and autonomy of the connected local sites.…”

Cataloged from PDF version of article.In this paper, we present a new transaction execution model that captures the\ud formalism and semantics of various extended transaction models and adopts them to a\ud multidatabase system (MDBS) environment. The proposed model covers nested transactions,\ud various dependency types among transactions, and commit independent transactions.\ud The formulation of complex MDBS transaction types can be accomplished easily\ud with the extended semantics captured in the model. A detailed performance model of\ud an MDBS is employed in investigating the performance implications of the proposed\ud transaction model. © Elsevier Science Inc. 1997

“…In the nested transaction model, a parent transaction may contain multiple sub-transactions [8] [10], and some sub-transactions may have the same function. The sub- transaction set composed of transactions with the same function is called a functional alternative set [11]. When to prepare a functional alternative set is depends, so in this paper, we divide the nested transaction model into the following three categories:…”

Open reconfigurable network (ORN) is proposed to meet users’ diversified and dynamic requirements. Path deployment is a typical service in the ORN, and can be executed in the way of open nested transaction for high efficiency. In this transaction, each operation on network nodes (NNs) is a sub-transaction, which costs CPU resources. In this paper, first we build the cost model of the path deployment of three kinds of sub-transactions execution—prepare in advance, implement concurrently and prepare dynamically. Secondly, we analyze two main approaches of path deployment in the ORN—unicast and multicast, and we concluded that multicast costs more than unicast when we ignore the time. Finally, based on the comprehensive consideration of cost and time, we propose the optimal way to execute nested transaction in the ORN.
