ABSTRACT:
Disclosed techniques include a method and apparatus that allow traffic to be switched between a working copy and a protected copy hitlessly. The control method simplifies implementation by advantageously distinguishing points within the apparatus wherein the working and protect streams should be virtually identical and aligned and points where the streams need only be identical but are tolerant of skew.
