Characterizing Network Traffic in a Cluster-based, Multi-tier Data Center

Deniz Ersoz, Mazin S. Yousif, Chita R. Das
2007 27th International Conference on Distributed Computing Systems (ICDCS '07)  
In view of this, there has been a significant amount of work to characterize the workloads of Web-based services.  ...  However, all of the previous studies focus on a high level view of these servers, and analyze request-based or session-based characteristics of the workloads.  ...  Therefore, most of the data centers consist of several tiers of servers in order to simplify the design and monitoring of large-scale systems ( Figure 1 ).  ...
