Course Overview

The objective of this lecture is to introduce performance modeling of complex distributed systems.

  • Server dimensioning of planned systems
  • Quality of service guarantees in distributed systems
  • Resource management in distributed systems

The focus will be on different analytical methods for performance modeling, namely stochastic network calculus (SNC) with

  • Moment generating functions (MGFs)
  • Tail bounds
