SDN-R Geo-Redundancy

Levels of Redundancies

Level 0: no redundancy
Level 1: support manual failure detection & rerouting or recovery within a single site; expectations to complete in 30 minutes
Level 2: support automated failure detection & rerouting
- within a single geographic site
- stateless components: establish baseline measure of failed requests for a component failure within a site
- stateful components: establish baseline of data loss for a component failure within a site
Level 3: support automated failover detection & rerouting
- across multiple sites
- stateless components
  - improve on # of failed requests for component failure within a site
  - establish baseline for failed requests for site failure
- stateful components
  - improve on data loss metrics for component failure within a site
  - establish baseline for data loss for site failure
