LiveLink
LiveLink is a feature of ASP that is available for the Smart Load Balancing (SLB)
and SLB (Auto-Fallback Disable) types of teaming. The purpose of LiveLink is to
detect link loss beyond the switch and to route traffic only through team members
that have a live link. This function is accomplished though the teaming software.
The teaming software periodically probes (issues a link packet from each team
member) one or more specified target network device(s). The probe target(s)
responds when it receives the link packet. If a team member does not detect the
response within a specified amount of time, this indicates that the link has been
lost, and the teaming software discontinues passing traffic through that team
member. Later, if that team member begins to detect a response from a probe
target, this indicates that the link has been restored, and the teaming software
automatically resumes passing traffic through that team member. LiveLink works
only with TCP/IP.
LiveLink is supported in both 32-bit and 64-bit Windows operating systems. For
similar capabilities in Linux operating systems, see the Channel Bonding
information in your Red Hat documentation.
