Hi, I'm wondering if there's a reliable and public survey, statistics about the distribution of datacenter (or cloud, if you wish) traffic, according to protocols or traffic types? E.g. the share of iscsi/fcoe/etc in storage, or the share of TCP/UDP, and so on. For general, Internet traffic, i've found several, for example: - Cisco Visual Networking Index, http://www.cisco.com/en/US/solutions/collateral/ns341/ns525/ns537/ns705 /ns827/white_paper_c11-481360_ns827_Networking_Solutions_White_Paper.ht ml - Arbor Networks survey, http://www.arbornetworks.com/en/arbor-networks-the-university-of-michig an-and-merit-network-to-present-two-year-study-of-global-int-2.html I'd be interested in seeing something similar for datacenter traffic, for research purposes. Thanks for you help in advance, Gergely -- Gergely Paljak
