A computing power allocation model in distributed database systems

The system under study consists of nodes connected to each other by virtual circuits within a communication network, such as a packet switching network. Each node (a host computer or a set of host computers) consisting of input and output M/M/1 processes has a unique database. The nodes and communication network form a product-form queuing network. The Lagrangian method is used for solving our model which allocates the processing capacity to M/M/1 processes.
