Abstract

A method and system for providing protection of multiple communication sessions using the bandwidth resources on the order of those required to protect a single communication session. This is facilitated through the use of network coding on a protection cycle. Transmissions from all connections are coded together using network coding and transmitted in two different directions on a cycle, so that the signal can be recovered by the receiver in two ways: on the working path, and on the protection (cycle) path.
