William M. Mellette, Rajdeep Das, Yibo Guo, Rob McGuinness, Alex C. Snoeren, George Porter
2019 arXiv   pre-print
The key to Opera's design is the rapid and deterministic reconfiguration of the network, piece-by-piece, such that at any moment in time the network implements an expander graph, yet, integrated across  ...  time, the network provides bandwidth-efficient single-hop paths between all racks.  ...  Consider an all-to-all shuffle operation, where a large number of hosts simultaneously need to exchange a small amount of data with one another.  ...

Routing in multihop packet switching networks: Gb/s challenge

C. Baransel, W. Dobosiewicz, P. Gburzynski
1995 IEEE Network  
Perhaps the cost of using fixed routing tables describing exactly the network topology will be paid off by the real simplicity of the routing rules and the flexibility of the network structure.  ...  Using these solutions as examples, they identify the specific problems resulting from very high transmission rates and explain how these problems influence the design of high-speed networks and protocols  ...  Figures 1-3 depict three shuffle-like networks with p = 2. Shuffle-like networks based on de Bruijn graphs are defined when N is a power of the connectivity degree p.  ...

LightFDG: An Integrated Approach to Flow Detection and Grooming in Optical Wireless DCNs [article]

Amer AlGhadhban, Abdulkadir Celik, Basem Shihada, Mohamed-Slim Alouini
2019 arXiv   pre-print
The proposed FD scheme has the flexibility of being implemented as in-network or centralized to classify flows of modifiable and unmodifiable hosts, respectively.  ...  Therefore, a fast-lightweight-and-accurate flow detection framework is developed by leveraging the transmission control protocol (TCP) behaviors.  ...  ) policy is designed to handle the two main flow classes (i.e., MFs and EFs) by separately routing them over disjoint virtual topologies.  ...

Channel Exchanging Networks for Multimodal and Multitask Dense Image Prediction [article]

Yikai Wang, Wenbing Huang, Fuchun Sun, Fengxiang He, Dacheng Tao
2021 arXiv   pre-print
Specifically, the channel exchanging process is self-guided by individual channel importance that is measured by the magnitude of Batch-Normalization (BN) scaling factor during training.  ...  In this paper, we propose Channel-Exchanging-Network (CEN) which is self-adaptive, parameter-free, and more importantly, applicable for both multimodal fusion and multitask learning.  ...  These scaling factors further guide the then each time of channel exchanging by Eq. 4 (assumed channel exchanging process that exchanges a portion of no crossmodal  ...

Neural network design of a banyan network controller

T.X. Brown, K.-H. Liu
1990 IEEE Journal on Selected Areas in Communications  
All my experiences at Caltech are intimately intertwined with her. iv Abstract A neural network is a highly interconnected set of simple processors.  ...  The many connections allow information to travel rapidly through the network, and due to their simplicity, many processors in one network are feasible.  ...  Although the non-blocking switches outperform the Banyan network, this better performance should be viewed in light of the extra complexity of a non-blocking switch.  ...
