Chapter 16. Platform Dependent Features
16.1 High Availability (HA) (WHG321, WHG325,
WHG405, WHG515, WHG525, WHG707,
WHG711, WHG801)
The 4ipnet HA design principle is to use redundancy in achieving higher availability
with minimum impact during service transition. The 4ipnet HA approach implements
a dedicated message link between ACs (Access Controller) to create an N + 1
redundancy system where N is ≤ 3. Once the HA link has been established, the
Active ACs will be servicing all network traffic while the Standby AC will be in hot-
standby ready to take over network service in case an Active AC can no longer
provide service.
