LiveLink
LiveLink is a feature of QLASP 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.
