Data Center Networks (DCNs) constitute the communication backbone for the cloud computing paradigm. Recently, network connectivity analysis in terms of reliability has received attention from the network research community. The traditional network features are useful; however, they are insufficient to determine how well-connected or well-designed a DCN is against the node or link removals. In this paper, the authors present a connectivity analysis of three well-known DCN architectures, namely: ThreeTier, FatTree and DCell. Their analysis reveals that the classic connectivity measures are inadequate for evaluating DCN connectivity.
