Global Availability is a static load balancing mode that bases connection
distribution on a particular server order, always sending a connection to the
first available server in the list. This mode differs from Round Robin mode
in that it searches for an available server always starting with the first server
in the list, while Round Robin mode searches for an available server starting
with the next server in the list (with respect to the server selected for the
previous connection request).
A hops factory is a type of factory run by the big3d agent that collects hops
data about network paths.
A host is a network server that manages one or more virtual servers that the
3-DNS Controller uses for load balancing.
ICMP is an Internet communications protocol used to determine information
about routes to destination addresses, such as virtual servers managed by
3-DNS Controllers and BIG-IP systems.
An internal interface is a network interface that can be accessed from a
local-area network (LAN). See also external interface.
The iQuery protocol is used to exchange information between 3-DNS
Controllers, BIG-IP systems, EDGE-FX Caches, and GLOBAL-SITE
Controllers. The iQuery protocol is officially registered with IANA for
port 4353, and works on UDP and TCP connections.
The Kilobytes/Second mode is a dynamic load balancing mode that
distributes connections based on which available server currently processes
the fewest kilobytes per second.
The Least Connections mode is a dynamic load balancing mode that bases
connection distribution on which server currently manages the fewest open
connections.
Load balancing methods are the settings that specify the hierarchical order
in which the 3-DNS Controller uses three load balancing modes. The
preferred method specifies the first load balancing mode that the 3-DNS
Controller tries, the alternate method specifies the next load balancing mode
