Abstract
A method of providing path protection includes setting a working path and a protection path by identifying, as a single path, a set of a control-purpose virtual network identifier and at least one virtual network identifier that are assigned to one or more users at a section defined as a point-to-point connection in a virtual network, and switching between the working path and the protection path.
