Loading Data From Global Server

Components of a Global Server Load Balancing (GSLB) Setup

A typical Global Server Load Balancing (GSLB) setup consists of the following components:

Global Server Load Balancing Domain: The Global Server Load Balancing Domain is a publicly resolvable domain or zone for which the Global Server Load Balancing setup is responsible. You can set up a NetScaler appliance to be the Authoritative Server for this domain or to proxy the information to an internal DNS server.
Global Server Load Balancing Site: The Global Server Load Balancing Site is the top-level entity for the Global Server Load Balancing communications. The information used when configuring the site is used for linking LOCAL sites to REMOTE sites and sharing monitoring data by using the Metric Exchange Protocol (MEP). The IP address used must be owned by the NetScaler appliance, such as subnet IP (SNIP), and must use TCP port 3011.
Global Server Load Balancing VServer: The Global Server Load Balancing VServer is used as the decision intermediary for directing client requests to the Load Balancing VServers of one of the GSLB site. The Global Server Load Balancing VServer is bound to a Global Server Load Balancing service.
Global Server Load Balancing Service: The Global Server Load Balancing Service is basically a monitoring link to the Load Balancing VServer. The Global Server Load Balancing Service monitors the link to the Load Balancing VServer that is created on the NetScaler appliance. The state of the local Global Server Load Balancing Service depends on the corresponding local virtual server state.
