Flash Response Mode A solution to DNS site balancing based on network latency. Rather
than attempt to actual measure network latency to a client DNS
server, Flash DNS broadcasts separate responses simultaneously
from each of the balanced sites. The response from the site with the
least network latency to the client DNS server arrives first to be used.
All other responses are discarded by the client DNS server as part of
normal DNS protocol.
Flash Peer Broadcaster of a Flash DNS answer.
Flash Source A Flash Source is the Flash Peer that is responsible for referring VIPs
associated with an Agent or Pseudo-Agent when Flash DNS site
balancing is used. The Flash Source generally must be on the same
network as the Agent/Pseudo-Agent or at least behind the same
router. When Flash DNS support is enabled on a load balancer, both
the Flash Source and Agent have the same address (the online outside
IP address of the load balancer).
Global Sync The process of automatically transferring (copying) the primary 7190
configuration to a secondary 7190.
HTTP Hypertext Transfer Protocol: the protocol used between a web
browser and a server to request a document and transfer its contents.
HTTPS HTTP exchanged over an SSL-encrypted session.
IP Internet Protocol
IP Address A unique identifier for a node on an IP network. Expressed in “dotted
decimal” notation. For example: 10.0.0.1.
IP Service A network-accessible, IP-accessible Application Protocol. For
example: HTTP, FTP, and the like. For administration purposes of
the Intel Netstructure products, services are identified by Virtual
IP:Port.
ISV Intelligent Site Verification. Intelligent Site Verification is used to
determine the availability of a third-party load balancer site. Methods
of verification include a site ping, TCP connect, and HTTP probe.
ITM (Internet Traffic
Manager)
Intel® NetStructure™ 7140 and 7170 Traffic Director products, used
for load balancing.
Least Connections This algorithm sends requests to the site with the lowest number of
connections. Least connections offers more effective management
for long sessions, such as FTP.
