• Set up load balancing among BIG-IP systems, EDGE-FX Caches, and
other load-balancing hosts
• Monitor real-time network conditions
The 3-DNS Controller supports both the standard DNS protocol and the
3-DNS iQuery protocol (a protocol used for collecting dynamic load
balancing information). The 3-DNS Controller also supports administrative
protocols, such as Simple Network Management Protocol (SNMP), and
Simple Mail Transfer Protocol (SMTP) (outbound only), for performance
monitoring and notification of system events. For administrative purposes,
you can use SSH, RSH, Telnet, and FTP. The Configuration utility supports
HTTPS, for secure web browser connections using SSL, as well as standard
HTTP connections.
The proprietary 3-DNS SNMP agent allows you to monitor status and
current traffic flow using popular network management tools. The 3-DNS
SNMP agent provides detailed data such as current connections being
handled by each virtual server.
The 3-DNS Controller offers a variety of security features that can help
prevent hostile attacks on your site or equipment.
◆
Secure administrative connections
The 3-DNS Controller supports Secure Shell (SSH) administrative
connections using the Mindterm SSH Client, for browser-based remote
administration, and SSH for remote administration from the command
line. The 3-DNS web server, which hosts the web-based Configuration
utility, supports SSL connections as well as user authentication.
◆
Secure iQuery communications
Crypto versions of the 3-DNS Controller also support Blowfish
encryption for iQuery communications between the 3-DNS Controller
and other systems running the big3d agent.
TCP wrappers
◆
TCP wrappers provide an extra layer of security for network connections.
The 3-DNS Controller is a highly scalable and versatile solution. You can
configure the 3-DNS Controller to manage up to several hundred domain
names, including full support of domain name aliases. The 3-DNS
