queueing applications

• applications
  
  
  • after-the-fact analysis based on actual values
    
    
  • make simple projection by scaling up from existing data
    
    
  • develop analytic model based on queueing theory
    
    
  • run simulation based on queueing model
    
    
• limitations
  
  
  • Poisson inputs often assumed
    
    
    • under-estimation for bursty inputs
      
      
      • e.g., 1st generation ATM switch with small buffer
