Abstract
The paper presents a tutorial on multilayer recovery methods. Emphasis is
laid not on their procedural operation, but rather on their quality
assessment and differentiation based on reliability parameters (e.g.,
availability, recovery time) and other relevant features (e.g., affected
traffic, state overhead).A brief outline of terminology related to multilayer networks is given.
Then, an overview of recovery methods is presented, with focus on multilayer
recovery. Next, quality features enabling assessment of multilayer recovery
are given along with general approaches to service differentiation based on
resilience.
