Improved Bounds for Flow Shop Scheduling
We resolve an open question raised by Feige & Scheideler by showing that the best known approximation algorithm for flow shops is essentially tight with respect to the used low...

Minimizing Stall Time in Single and Parallel Disk Systems Using Multicommodity Network Flows
We study integrated prefetching and caching in single and parallel disk systems. A recent approach used linear programming to solve the problem. We show that integrated prefetching...

Efficient resource management for hard real-time communication over differentiated services architectures
We propose an efficient strategy for resource management for scalable QoS guaranteed real-time communication services. This strategy is based on sink trees, and is particularly we...

A Per-Flow Based Node Architecture for Integrated Services Packet Networks
As the Internet transforms from the traditional best-effort service network into QoS-capable multi-service network, it is essential to have new architectural design and appropriate...

Hardness of Directed Routing with Congestion
Given a graph G and a collection of source-sink pairs in G, what is the least integer c such that each source can be connected by a path to its sink, with at most c paths going th...
