Kandula et al (2009) Flyways To De-Congest Data Center Networks (HotNets)

April 12, 2010 paper

This paper says, if we require a network to be not oversubscribed, the cost is high. For example, if we use fat-tree topology, the networking cost is 2-3x of a tree topology. Using VL2 is even 4-5x. However, it is not necessary to prevent oversubscription because in most of the... [more]

Mosko et al (2005) Multipath Routing in Wireless Mesh Networks (WiMesh)

April 11, 2010 paper

This paper proposes an algorithm for performing multipath routing in wireless mesh network. The authors argue that, in case of multipath routing, requiring different paths to be link disjoint is not as good as allowing partially shared paths from the reliability perspective. [more]
