A Survey of Network Topology of Data Center
Xin He, Mingshu He, Zhijie Han · 2018
Data center is used as a network infrastructure for carrying, transmitting, storing and processing big data, which plays an important role in the application of cloud computing, CDN distribution, etc. The network topology is the theoretical foundation and deployment basis of fault-tolerant redundancy and elastic scaling in the data center. The state-of-the-art server-centric network topologies such as DCell were firstly emphatically analyzed, systematical summaries and theoretical analyses were made for their structure definition and generation model. And on this basis, the comparison and evaluation were conducted finally from the dimensions such as coverage diameter, connectivity and equal width etc.
