An experimental multihop packet radio network, SOFTNET, is described. The concept of "soft? protocols for experimental packet switched networks is introduced. Using this scheme, network nodes can be easily reprogrammed to provide new user services during normal operation. The SOFTNET Network programming language is described. Further, the hardware and software implementation of the network is o...

Contention of communications across a switched network that connects multiple compute nodes in a distributed-memory cluster may seriously degrade performance of parallel code. The InfiniBand network is the most popular interconnect for compute clusters. While one may correctly assume that increased resource contention leads to decreased application performance, alternate methods such as virtual...

The recent emergence of multimedia applications has led to the deployment of various telecommunication technologies (e.g. IP, wireless) in addition to traditional PSTN (Public Switched Telephone Network) circuit switched networks. In this heterogeneous telecommunication world, users make calls without regard to the fact that the originating network may differ from the terminating network, and t...

In this paper, we propose a feasibility analysis of periodic hard real-time traffic in packet-switched networks using First Come First Served (FCFS) queuing but no traffic shapers. Our work constitutes a framework that can be adopted for realtime analysis of switched low-cost networks like Ethernet without modification of the standard network components. Our analysis is based on a flexible netw...

The demand of integration of many heterogeneous semiconductor intellectual property (IP) blocks has been introducing a new chip design paradigm so called on chip network. This paradigm promisingly offers a packet switched network among IPs to reduce the main problems in the very deep sub micron technologies that arise from non-scalable global wire delay, failure to achieve global synchronizatio...

The Gemini interconnect is a dual technology (optical and electrical) interconnection network designed for use in tightlycoupled multicomputer systems. It consists of a circuit-switched optical data path in parallel with a packet-switched electrical control/ data path. The optical path is used for transmission of long data messages and the electrical path is used for switch control and transmis...
