Downlink BandWidth Busy Rate
When the percentage of the actual downlink bandwidth of a physical link
to maximum downlink bandwidth reaches this busy rate, the physical link
is busy.
Cost Cost of the physical link.
ISP
ISP to which the physical link belongs.
If no ISP is specified, the physical link does not participate in ISP routing.
IMPORTANT:
Support for the ISP option and the available ISPs depends on the device
model.
205BConfiguring the best performing link function
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. 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.
Network delay, router hops, bandwidth, and cost refer to the following:
• 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 has a higher priority than a
dynamic best performing link entry.
379BConfiguring dynamic best performing link parameters
1. Select High Reliability > Load Balance > Link Load Balance > Best-Performing Link from the
navigation tree.
The Parameters of Dynamic Best-Performing Link configuration page appears.
