Wang et al (2010) c-Through: Part-time Optics in Data Centers (SIGCOMM)

August 2, 2010 paper

This paper proposed a term, HyPaC network, for hybrid of packet and circuit switched network. The packet switched network are commodity electrical ethernet switch and the circuit switched network is optical connections. This paper built a HyPaC testbed, c-through. [more]

Doyle et al (2010) An Experimental Evaluation of Distributed Rate Limiting for Cloud Computing Applications (ANCS)

July 17, 2010 paper

Assuming there are \(N\) different data centers together worked as a computation cloud. User submit job to one of the \(N\) data center but the SLA upperbounded the total throughput over all \(N\) data centers. [more]

Abu-Libdeh et al (2010) Symbiotic Routing in Future Data Centers (SIGCOMM)

July 17, 2010 paper

A paper from Microsoft Research UK. The focus is on a topology named CamCube, which is a 3D torus with no switch node. All nodes in the topology is connected to 6 other nodes to form a 3D lattice. Nodes are addressed by a 3D coordinate, \((x,y,z)\). Routing is done... [more]

Kamp (2010) You're doing it wrong (CACM)

July 17, 2010 paper

This is written by a FreeBSD kernel developer. It discussed the effect of OS-level caching to algorithm performance. The story is that, one has to do store/retrieve operation on a heap. If the heap is made of a balanced binary tree, usually it is implemented as an array such that... [more]

Clévenot et al (2005) Stochastic fluid models for cache clusters (PE)

June 25, 2010 paper

This paper models the hit rate of a cluster of cache servers. [more]
