Simplex Queues for Hot-Data Download

Mehmet Fatih Aktas, Elie Najm, Emina Soljanin
2017 Performance Evaluation Review  
Data download from these systems involves multiple fork-join queues operating in-parallel, making the analysis of access time a very challenging problem.  ...  Speci cally, using a queueing theoretic approach, we derive bounds and approximations on the average response time for two di erent Poisson request arrival models.  ...  EXPECTED HOT-DATA DOWNLOAD TIME We are interested in analyzing how the availability provided by the simplex setup a ects the download time of hot-data.  ...
