In the 1-rate(f) network, each link can carry up to f messages for some integer f . The classical model is the special case when f = 1. We show that a network is strictly nonblocking under the 1-rate(f) model if and only if it is strictly nonblocking under the classical model.

We study local structure of time-optimal controls and trajectories for a 3dimensional control-affine system with a 2-dimensional control parameter with values in the disk. In particular, we give sufficient conditions, in terms of Lie bracket relations, for optimal controls to be smooth or to have only isolated jump discontinuities.

We study the dynamics of the switching process in a magnetic tunnel junction composed of 5 layers with the magnetization of the two side layers fixed. The magnetization of the middle free layer can be switched between the two stable configurations by passing the current through the tunnel junction in a certain direction. The dependence of the switching time on the parameters of the penta-layer ...

Based on measurements of a prototype, we identify hardware requirements for improving the performance of hybrid electrical-packet-switched/optical-circuit-switched data center networks. OCIS codes: (200.4650) Optical interconnects; (200.6715) Switching; (060.4253) Networks, circuit-switched

In this paper we compare characteristics of different FIFO packet switch types. In accordance with our expectations, the best results are obtained by using the output-queued packet switches. The main drawback of these switches is the need for a fast switching fabric. This can be avoided by using the input-queued packet switches, whose performance depends upon individual packet sizes. Characteri...

This paper proposes a novel dataflow architecture called DFNET (DataFlow architecture on the interNET), which realizes a scalable dynamic dataflow computer on a packet switching network. A vast amount of research on dataflow computers has been extensively performed during, in particular, 1970s and 1980s as a promising approach for realizing very high-speed computers. In spite of the large amoun...
