Task Remarks
Configuring the Best Performing Link
Function
Optional
Allows you to configure dynamic best performing link parameters and
static best performing link entries.
For outbound link load balancing, the best performing link function
allows you to forward packets whose destination address matches the
best performing link entry over the link in the entry. If no matched entry
is found, best performing link detection is performed, that is, the device
selects the best link to the destination segment from among multiple
links according to the network delay, router hops, bandwidth, cost and
weight of the links, and generates a dynamic best performing link
entry, where:
•
Network delay and router hops are obtained through health
monitoring.
•
Bandwidth is the available bandwidth of the links.
•
Cost is specified in the configuration of the physical links.
You can also manually add a static best performing link entry, which is
of a higher priority than a dynamic best performing link entry.
By default, each dynamic best performing link entry has its default
value, and there is no static best performing link entry in the system.
IMPORTANT:
For outbound link load balancing, this function is available only when
enabling of best performing link is configured in a virtual service.
Required
Allows you to create a logical link group and configure parameters of
the logical link group.
By default, no logical link group exists in the system.
Required
Allows you to create a logical link and add it to the corresponding
logical link group.
By default, no logical link exists in the system.
Required
Allows you to create a virtual service and reference the corresponding
logical link group.
By default, no virtual service exists in the system.

Optional
Optional
To remove the physical link corresponding to a logical link from a
cluster, you can enable slow-offline for the logical link. After
slow-offline is enabled, the LB device will not assign new services to the
logical link and you can remove the physical link from the cluster after
the original services of the logical link are processed.
The slow-offline function can avoid the service interruption caused by
sudden removal of a physical link.
