Presented are methods and apparatus for protecting a plurality of High Availability (HA) Service Instances (Sls) with a plurality of Service Units (SUs) with an Nway redundancy model. Any of the SUs associated with the Nway redundancy model can simultaneously be assigned an active HA state for some of the Sls and a standby HA state for other Sls. However, only one SU can have the active state for any given Sl. The Nway redundancy model is a configured prior to runtime operation. |
