A Policy Aware Switching Layer for Data Centers. UC Berkeley Technical Report No. UCB/EECS-2008-82. The authors deal with the problem of configuring middleboxes in datacenters. Current architectures call for middleboxes to be placed on the physical network path, which leads to a number of ... http://blogs.sanmathi.org/nalanda/2008/11/25/a-policy-aware-switching-layer-for-data-centers/ Zaharia, M., Konwinski, A., Joseph, A.
