On cross-bandwidth

J. Kahn, D.J. Kleitman
1981 Discrete Mathematics  
The notion of cross-bandwidth is introduced, and it is contractible to a k-connected graph has cross-bandwidth shown that any graph that is suitably at least k.  ...  The contracted edges mtst induce in the original graph a subgraph of maximum degree at most one. This is used to reso! de a conjecture of Erd& and Chinn on the bandwidth of certain graphs.  ...  In this note we introduce the concept of cross-bandwidth, and show that the cross-bandwidth of a graph that can be contracted in a certain way to one that is "k-connected" is at least k.  ...

Fbufs: a high-bandwidth cross-domain transfer facility

Peter Druschel, Larry L. Peterson
1993 Proceedings of the fourteenth ACM symposium on Operating systems principles - SOSP '93  
As network bandwidth approaches memory bandwidth, copying data from one domain to another simply cannot keep up with improved network performance [15, 7] .  ...  For the most part, this earlier work focuses on lowering control transfer latency-it assumes that the arguments transferred by the cross-domain call are small enough to be copied from one domain to another  ...  This case serves as a baseline for evaluating the impact of domain boundary crossings on throughput. The user-user case involves a kernel/user boundary crossing on each host.  ...

Lingzhen Zeng, Charles L Bennett, David T Chuss, Edward J Wollack

Corrugated feed horns offer excellent beam symmetry, main beam efficiency, and cross-polar response overwide bandwidths, but can be challenging to fabricate.  ...  The feed was demonstrated to have low cross polarization (<-30 dB) across the frequency range 33-45 GHz (30% fractional bandwidth). A power reflection below -28 dB was measured across the band.  ...  Using this flexible approach, we have demonstrtted a design having za 30`-t bandwidth with cross-polar response below -30 dB.  ...

Javier Salido, Loukas Lazos, Radha Poovendran
2007 IEEE/ACM Transactions on Networking  
We propose a cross-layer heuristic algorithm called VP3 that bounds member key storage, and GC transmissions, while significantly reducing the energy and bandwidth consumption of the network.  ...  Finally, we propose On-line VP3 which dynamically updates the key assignment structure according to the dynamics of the communication group in a resource-efficient way.  ...  Since energy is, in most cases, a more scarce resource than bandwidth, we focus on finding an energy-efficient solution and show that our scheme is also bandwidth-efficient.  ...
