Abstract
The performance of multiple-bus networks with full bus-memory connection, single bus-memory connection, and partial bus-memory connection are presented. A type of multiple-bus network, called a partial bus network with K classes, is proposed. Under a nonuniform requesting model called a hierarchical requesting model, the performance of the above multiple-bus networks is analyzed. The costs and fault-tolerant capabilities of each are evaluated and compared with one another. It is shown that the proposed networks are useful in applications requiring high performance and degree of fault tolerance with moderate cost.
