The primary purpose of this presentation is to list and analyze the currently available Global Server Load Balancing (GSLB) methods. A new GSLB technique along with the testing results is presented that is shown to be the most efficient solution in some network setups. Various GSLB network scenarios are considered, ranging from a set of few GSLB'ed servers to global content delivery ASP network setups. What GSLB method should be used in what network setup is also discussed.
